The plant is fuelled by blast furnace gas (BFG) and coke oven gas (COG) from the Algoma Steel plant operations, and it generates both electricity and process steam. The plant consists of two 371,300 lb/hr BFG/COG fuel-fired boilers and one 100 MW condensing steam turbine generator installed in an existing steel mill building.
The ignition temperature of coke oven gas is higher, once ignited, they burn quickly, the gas explosion limit is low, and easy to explode after mixing into air, thus the boiler furnace is designed as square form and the burners are arranged at the corners.
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.
Blast furnace gas is a by-product of blast furnaces where iron ore is reduced with coke into metallic (pig) iron. The gas has a very low heating value of around 0.9kWh/Nm 3 , which on its own is typically not high enough for combustion in a gas engine.

Coke is an essential input to the steel-making process and is produced by heating coal in coke ovens. To make coke, coal is heated in the absence of oxygen to drive volatile matter from it. Coke oven gas, a low-BTU gas, is produced as a by-product of the process. Approximately 40% of the COG is used as a fuel in the coke oven.
