- 2. Introduction • Analyse specific trends or record data • Physical properties can be measured with the sensors • The sensors send signals to the interface box, which is linked to a computer • The interface box converts analogue signal to digital signals • Reading will be more accurate
- 3. What is this? What is combustion? What are the applications of combustion in human life? What process involves to produce this? How combustion occurs? What is the chemical reaction of reaction? This is FLAME or we called it as FIRE. COMBUSTION produces flame or fire.
- 4. Apparatus: Candle, bell jar, matches, interface, computer and temperature, light and humidity sensors. Procedure: 1. The apparatus was set up and sensors were arranged inside the bell jar. 2. The sensors were connected to the interface. 3. The candle was lighted up and covered with the bell jar. 4. The experiment was recorded for 3 minutes. 5. When the candle extinguished, the air was readmitted into the bell jar.
- 5. Discussion
- 6. IMPORTANCE OF COMBUSTION • Industrial process o Cement industry is the heavy user of heat energy delivered by combustion o Iron, steel, aluminium and other metal refining industries employ furnaces for producing raw products o Other examples of industrial devices are boiler, refinery, glass melters and also solid dryers. • Transportation system o Air craft – powered by fuel burning o Trains – diesel engines o Domestic vehicles – use gasoline • Our lives would be completely different if combustion reactions did not exist!
- 7. • Ethanol which mixed with gasoline used in internal combustion engine • Alcohol will produce low energy • Reaction pure hydrogen gas and oxygen Alcoholic Substance in Combustion
- 8. Rocket Propulsion Products of combustion (solid, liquid, gas) in rocket ejected from combustion chamber at high velocity Mixtures of low molecular weight and high heat of combustion therefore used for rockets.
- 9. Explosives Combustion and detonation are widely used in all sorts of work with mechanical action or explosion Combustion of condensed explosives occurs mostly in gas phase, which provide burning velocity, depends on temperature, pressure and parameters Will results of experimental investigations on combustion and detonation.
- 10. Combustion Turbine • The combustion turbine have three main phases. • Combustion phase : • A ring of fuel injectors inject a steady stream of fuel mixed with air into combustion chamber . • Mixture is burned at >2000 F • High temperature, high pressure • Causes the aerofoil to rotate.
- 11. Conclusion • One of the method used to handle experiment easily • Organize our result or data well by the usage of ICT • By using the sensor, the data was inter-related • Easy to present result and clearly know the fact within the sensor
