Fuels Engineering Chemistry Quiz

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.
