In a coal-based synthetic gas production facility, 40% of the fuel follows the generator gas cycle and the rest, 60%, is used in the water gas cycle.

The coal consists of 90% carbon and 10% ash. Assume negligible carbon losses in the ash. In the generator gas cycle, half of the carbon produces CO and the other half produces CO2. The oxygen is completely consumed. Dry air is used. The water gas cycle operates at 1000K and 1.09 atm. Assume that the carbon is completely consumed and the steam is fed in 50% excess.

Determine:

Composition of the gas generator and water gas.

Operating temperature of the gas generator cycle.

Heating values for the two gases per kg of carbon fed.

The H2-to-CO ratio of the mixed gases.
