Quick Reference to Installation and Testing
1. Install the burner (with an air cylinder of 114 mm). Connect the oil piping and air
piping.
2. Fill around 1.5 liter waste engine oil into the smaller oil tank until the heater is
submerged.
3. Fill the fuel oil into the bigger oil tank fully. (It should be done like this everyday
so as to prevent the oil-pumping system from exhausting the tank. And some
priming oils may be filled at the outlet pipe of the oil pump if the oil-pumping
system exhausts the tank unintentionally).
4. Connect to the power conductor (220 V/5 A) at the lower bigger oil tank. The oil
temperature in the bigger oil tank may maintain automatically the constant
temperature at about 40℃.
5. The power plug (220 V/10 A) on the right side of the burner should be connected
to the outlet line of control power supply on the electric control box of either the
baking varnish workshop or the boiler, while we ensure contacts of the controller
may have efficient capacity. If the capacity is inefficient, we should install an
additional relay (220 V/10 A).
6. After the power supply is connected, the oil service pump should be functioning,
and it won’t stop working automatically until the oil is transmitted into place. The
fuel oil starts heating when the heating indicator light gets on. The oil temperature
of the waste engine oil is determined at around 95℃. After 6-8 minutes when the
temperature is reached, the burner may function by firing. We should try to find
reasons (such as the waste engine oil has high water content, and the compressed
air can’t work normally) when we can’t fire the burner for the first and the second
times and we will go on firing after these problems are solved.
7. The size of the flame may be adjusted to the proper length by slightly adjusting
the pressure knob in accordance with the actual conditions (the capacity and size
of the thermal exchanger, and the blast volume), and we will press the button after
adjusting.
8. Observe the combustion situation of the flame through the observation window,
and loosen the set screws of the air shutter knob, and adjust the air shutter until it
has efficient combustion and complete emission. And fix the set screws of the air
shutter knob.
9. The testing is completed. But remember that don’t blend gasoline, antifreeze and
water into the fuel oil.
10. The unit should have a regular cleaning every other month. Loosen the hanging
nuts and pull out the burner to clear the carbon deposits on the air plate and the
fire stick. And re-assemble them as they had before cleaning. Look to the relative
position of the fire stick (as shown in the figure above).

I. Main Features
Qingdao Kingwei Energy Saving Equipment Co.,ltd specializes in producing Multi-Fuels Fired
Fully-Automatic Burner of Kingwei Brand. Having scientific design and using quality
components and having precision installation and testing, the equipment possesses the functions of
energy conservation and friendly-environment, as well uses multiple fuels especially the waste
fuel oils (waste engine oil and waste vegetable oil), and realizes the fully-automatic control over
the combustion process by adopting computerized control with the state patent (the state patent No.
200520000333.0) and the unique combustion technology. Widely used in the equipment integrated
with the heat exchanger, such as large and small-sized industrial and utility boilers, coating
machines and auto baking varnish workshops. Exhaust gas emission reaches the standards and the
unit is approved by the environment protection authorities. The unit has the following features
thanks largely to some measures on its design and construction:
Good fuel atomization, less energy consumption and low noises
The burner uses a special nozzle to burn and inject evenly fuels by using the compressed air as the
primary air. The fuel oil may obtain satisfactory atomization effect when the air pressure is ≥0.05
MPa. Therefore the unit has less energy consumption and low noises, because it needs no
atomization medium.
Good fuel-air proportioning, stable flame, high combustion efficiency and
friendly-environment
The burner uses cyclone and straight-through flow simultaneously, and may obtain relatively
satisfactory fuel concentration field by enabling the fuel and the combustion air to mix completely,
while the cyclone may cause the reflow of the hot flue gas, improving greatly the stability of the
flame. Therefore the unit may have an efficient and complete combustion and a thorough emission,
and has less pollution to environment, complying with the strictest regulations on air management
in the world.
Safe and reliable with fully-automatic control
The burner uses the world-class flame supervision and combustion safety controllers, realizing the
fully-automatic control including the air supply, firing, fuel injection, combustion, stop and re-start
according to the requirements for operation safety, and it may satisfy the technological
requirements of boilers and kilns. And it may stop automatically when there is trouble in any
process of the control.
Easy installation
Each burner is equipped with a sliding flange nested on the short blast pipe located at the rear of
the burner head. It may be operated only after the burner head will be placed in the correct
location by fixing the flange on the furnace and adjusting the position of the flange on the short
blast pipe, and after the power supply, the compressed air pipe and the oil-feeding pipe are
connected.
Convenient maintenance
Routine maintenance is taken into account in the design of the product. It is very convenient for
the key elements to dismantle, clean and change. And the unit adopts peculiar physical
phenomenon, and there are no wear parts and consumables during the routine operation, which
may lower costs considerably.

II. Range of Operation
As the heating object and its service situations of the burner differ, the pressure of the furnace
hearth varies. When the backpressure (pressure of the furnace hearth) of the burner increases, the
outlet airflow of the fan decreases, and then the injection pressure must be lowered or the injection
volume must be decreased by changing a smaller nozzle so that the flow of the fuel oil can be
matched with the airflow. The higher the backpressure is, the smaller the airflow of the fan is, the
smaller the combustion capacity of the burner. Therefore the burner may function within certain
range, when the backpressure is lifted to certain values, the airflow drops sharply, and firing and
combustion situations deteriorate greatly even the burner gets quenched, no matter how we
decrease the injection volume, we can’t ensure the burner may have a normal combustion.
III. Oil Supply System
They maintain good sealing when the filter, the coupling block and the oil-resistant hose are
installed at the outlet end of the fuel oil pump. The filter can’t be damaged, and change it if it is
damaged otherwise some foreign substances will enter the oil pump and block the precision oil
pump. The outlet hose is connected to the one-way valve, and the fuel oil is transmitted into
high-temperature fuel oil supply station through the copper tubing. The oil level of
high-temperature fuel oil supply consists of a level control float ball and a computer-controlled
switch. The oil level may be adjusted by adjusting the computer program.
IV. Main Construction
Photo Resistance
Photo resistance is a device that supervises the flame. Photo resistance may enable the controller
to stop working within 10 seconds and whilst on the controller fault indicator light (red) gets on,
because photo resistance can’t sense the luminosity of the flame if the flame can’t be fired or
flame is quenched during the operation when the burner initiates. On the contrary, under the
circumstances that there is a strong ambient light illumination, photo resistance may sense the
ambient lighting, and thinks the flame is burning, enabling the controller to have improper
operation, that is, the controller will not inject oil when starting while it will not stop injecting
when operating. Therefore we should dispel the interference of ambient lighting to the photo
resistance.
Fault Indicator Light (Red)
The controller will stop working within 10 seconds and the fault indicator light (red) gets on when
the burner can’t start or operate normally due to some reasons. Facing this we should try to find
the reasons possible to cause the troubles, and dispel the trouble, and then press the button of the
fault indicator light (red), the burner will function again.
According to the requirements users may install a fault warning device that will give a fault
alarming when the burner is in trouble. Once the red light gets on, the button of the fault indicator
light (red) can be pressed after around 1 minute. And the burner should be started again with the
manual reset.
Computer Program Controller
A computer program controller is a device controlling the normal and safe operation of the burner.
A series of program operating time has been preset to ensure the reliable and safe operation of the
burner for the sake of safety except that burner is started and operated with the prescribed
program.

between the compressor and the air piping to avoid the shutoff trouble caused by the water in the
air piping.
Special Parts
1. Oil Tank
2. Oils in the oil pre-heater/heating oil-storage tank. The power line in the plastic box mounted
at the bottom of the oil tank should be connected to the power supply directly.
3. Oil-pumping device should be mounted on the oil storage tank or the auxiliary oil storage
container connecting to the oil piping, which transmits automatically the fuel oil with a
preheating temperature of 40℃ into the smaller oil tank.
4. A floating sucker should be connected to the bottom of the oil piping and inserted into the oil
storage tank or the auxiliary oil storage container.
Preparations before Starting
If the unit is used for the first time, fill manually into the smaller tank of the burner to the half of
its charge.
Warning
When the oil level is too high, the float switch will turn off automatically; while the oil level is too
low, the heating pipe will be damaged.
The burner will function automatically when the fuel oil is heated to the prescribed temperature.
Rules
Establish the oil consumption by adjusting the primary air regulator.
Establish the emission of the exhaust gases by adjusting the second air regulator.

Safe and reliable with fully-automatic control The burner uses the world-class flame supervision and combustion safety controllers, realizing the fully-automatic control including the air supply, firing, fuel injection, combustion, stop and re-start according to the requirements for operation safety, and it may satisfy the technological requirements of boilers and kilns. And it may stop automatically when there is trouble in any process of the control.
  • 6. Easy installation Each burner is equipped with a sliding flange nested on the short blast pipe located at the rear of the burner head. It may be operated only after the burner head will be placed in the correct location by fixing the flange on the furnace and adjusting the position of the flange on the short blast pipe, and after the power supply, the compressed air pipe and the oil-feeding pipe are connected. Convenient maintenance Routine maintenance is taken into account in the design of the product. It is very convenient for the key elements to dismantle, clean and change. And the unit adopts peculiar physical phenomenon, and there are no wear parts and consumables during the routine operation, which may lower costs considerably. Fig 1 1. Oil Storage Tank 2.

Range of Operation As the heating object and its service situations of the burner differ, the pressure of the furnace hearth varies. When the backpressure (pressure of the furnace hearth) of the burner increases, the outlet airflow of the fan decreases, and then the injection pressure must be lowered or the injection volume must be decreased by changing a smaller nozzle so that the flow of the fuel oil can be matched with the airflow. The higher the backpressure is, the smaller the airflow of the fan is, the smaller the combustion capacity of the burner. Therefore the burner may function within certain range, when the backpressure is lifted to certain values, the airflow drops sharply, and firing and combustion situations deteriorate greatly even the burner gets quenched, no matter how we decrease the injection volume, we can’t ensure the burner may have a normal combustion.
  • 8. III. Oil Supply System They maintain good sealing when the filter, the coupling block and the oil-resistant hose are installed at the outlet end of the fuel oil pump. The filter can’t be damaged, and change it if it is damaged otherwise some foreign substances will enter the oil pump and block the precision oil pump. The outlet hose is connected to the one-way valve, and the fuel oil is transmitted into high-temperature fuel oil supply station through the copper tubing. The oil level of high-temperature fuel oil supply consists of a level control float ball and a computer-controlled switch. The oil level may be adjusted by adjusting the computer program. IV. Main Construction Photo Resistance Photo resistance is a device that supervises the flame. Photo resistance may enable the controller to stop working within 10 seconds and whilst on the controller fault indicator light (red) gets on, because photo resistance can’t sense the luminosity of the flame if the flame can’t be fired or flame is quenched during the operation when the burner initiates. On the contrary, under the circumstances that there is a strong ambient light illumination, photo resistance may sense the ambient lighting, and thinks the flame is burning, enabling the controller to have improper operation, that is, the controller will not inject oil when starting while it will not stop injecting when operating. Therefore we should dispel the interference of ambient lighting to the photo resistance. Fault Indicator Light (Red) The controller will stop working within 10 seconds and the fault indicator light (red) gets on when the burner can’t start or operate normally due to some reasons. Facing this we should try to find the reasons possible to cause the troubles, and dispel the trouble, and then press the button of the fault indicator light (red), the burner will function again. According to the requirements users may install a fault warning device that will give a fault alarming when the burner is in trouble. Once the red light gets on, the button of the fault indicator light (red) can be pressed after around 1 minute. And the burner should be started again with the manual reset.
  • 9. Computer Program Controller A computer program controller is a device controlling the normal and safe operation of the burner. A series of program operating time has been preset to ensure the reliable and safe operation of the burner for the sake of safety except that burner is started and operated with the prescribed program.

  • 10. V. Installation Burner and Flange Fix the flange and seal ring of the burner on the support. Oil Pipe Installation of oil pipe, oil storage tank, oil float and oil pump. If you store oil with an auxiliary oil tank outdoors, please mount the antifreeze equipment around both the pipe wall and container to prevent the water in the waste oil from freezing or prevent the waste oil from thickening Connection of Power Supply Put the plug on the burner into the socket on the boiler, and connect the power line of the thermostat on the bigger oil tank to the power supply. Connection of Compressed Air Supply Connect the air pump to the coupler of the air piping. We have installed an oil-water separator between the compressor and the air piping to avoid the shutoff trouble caused by the water in the air piping. Special Parts 1. Oil Tank 2. Oils in the oil pre-heater/heating oil-storage tank. The power line in the plastic box mounted at the bottom of the oil tank should be connected to the power supply directly. 3. Oil-pumping device should be mounted on the oil storage tank or the auxiliary oil storage container connecting to the oil piping, which transmits automatically the fuel oil with a preheating temperature of 40℃ into the smaller oil tank. 4. A floating sucker should be connected to the bottom of the oil piping and inserted into the oil storage tank or the auxiliary oil storage container. Preparations before Starting If the unit is used for the first time, fill manually into the smaller tank of the burner to the half of its charge. Warning When the oil level is too high, the float switch will turn off automatically; while the oil level is too low, the heating pipe will be damaged. The burner will function automatically when the fuel oil is heated to the prescribed temperature.
