Question

The amount of heat energy produced by one gram of a fuel on complete combustion
in air or oxygen is called the calorific value of the fuel.​

Answer 1

Explanation:

2.1.3 Calorific Value/Heating Value

The calorific value of LFG can be defined as the amount of heat produced on combusting a unit volume of gas and can be expressed in kcal/m3, kJ/m3, or BTU/ft3. Calorific value depends directly on the methane content of LFG, i.e., the higher the methane content, the greater the calorific value. As defined in previous sections, the composition of LFG varies with the age of the landfill, therefore calorific value also varies along with its composition. It has been reported that under good conditions, the calorific value of LFG can be expected to be approximately 7124 kcal/m3 during the methanogenic stage [29]
