Determine Material and heat balance of a gasifier and calculate efficiencies. The analysis of various inputs and outputs are given.
Temperatures of input and outputs are also given.

Basis 1 Kg coal.

Volume of producer gas (fuel gas)

Let Y Kg mole producer gas

Volume of air (moist)
Let X Kg mole moist air
Since the air is moist, we have to calculate composition of air.
