Furnace Gas for Power Production - clarke-energy

Coke Gas. Coke gas is a by-product of industrial coke production from coal created by high-temperature pyrolytic distillation of coking coal.The gas mainly consists of hydrogen (50-60%), methane (15-50%), a small percentage of carbon monoxide, carbon and nitrogen. With a calorific value of 5 kWh/Nm 3, coke gas constitutes a high-value fuel for effective power generation with Jenbacher gas engines.
