Coke is one secondary solid fuel obtained from coal.

The calorific value of a fuel is the amount of heat energy produced when one kilogram of the fuel is completely burned in air. It indicates the efficiency and quality of the fuel.

Liquid fuels are easier to handle, transport, and store. They burn more efficiently, produce less ash, and can be used directly in internal combustion engines.

The calorific value is determined using a bomb calorimeter, which measures the heat released during the complete combustion of a known quantity of fuel.

Calorific value refers to the total amount of heat energy obtained by the complete combustion of a unit mass or volume of a fuel.

It is determined experimentally using a bomb calorimeter under controlled conditions.

Destructive distillation is the heating of coal in the absence of air to obtain useful products like coke, coal gas, and coal tar.

Pulverized coal is coal that has been ground into a fine powder to increase its surface area, ensuring better combustion in furnaces.

Efficiency depends on factors such as moisture content, impurities, ignition temperature, and the calorific value of the fuel.

Petroleum is a naturally occurring liquid mixture of hydrocarbons found beneath the Earth’s surface. It is refined to produce fuels like petrol, diesel, and kerosene.
