Question

What are producer and water gas? Are they both he same? How is it made?

Answer 1

Producer Gas :
A gas mixture containing carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2) and nitrogen (N2). In the USA, producer gas is a generic term referring to wood gas, town gas, synthesis gas, syngas or raw gas. In the UK, producer gas, also known as suction gas, means a fuel gas made from coke or other carbonaceous material. Air is passed over the red-hot fuel and carbon monoxide is produced in an exothermic reaction which reads 2C + O2 → 2CO. The nitrogen in the air remains unchanged and dilutes the gas, so it has a low calorific value. The gas may be used to power gas turbines which are suited to fuels of low calorific value.

Water Gas:
A mixture of carbon monoxide (CO) and hydrogen (H2) produced by passing steam over red-hot coke using the endothermic reaction C + H2O → CO + H2. This product had a lower calorific value than coal gas so the gas was often passed through a heated retort into which oil was sprayed; the resulting mixed gas was called carburetted water gas.
