Study Notes
Fuel Classification
- Fuels are classified based on their occurrence as primary fuels and secondary fuels.
- Primary fuels are naturally occurring sources such as coal, oil, and natural gas.
- Secondary fuels are derived from the processing of primary fuels, such as refined petroleum products and biomass.
Types of Calorific Value
- The two types of calorific value are higher heating value (HHV) and lower heating value (LHV).
- HHV measures the total energy released when a fuel is burned, including the energy from condensed water vapor.
- LHV measures the energy released during combustion excluding the heat of vaporization of water.
Definition of Fuel
- A fuel is a substance that can release energy through chemical or nuclear reactions.
- Fuels are used to generate heat or power, commonly for transportation, heating, and electricity generation.
Purpose of Bomb Calorimeter
- A bomb calorimeter is used to measure the calorific value of fuels.
- It allows for accurate determination of the energy release from combustion by measuring temperature changes in a controlled environment.
Coal Analysis
- Coal is analyzed through various methods including proximate analysis, ultimate analysis, and calorific value determination.
- Proximate analysis evaluates moisture, volatile matter, fixed carbon, and ash content.
- Ultimate analysis determines the composition of carbon, hydrogen, sulfur, nitrogen, and oxygen in the coal.
