In a coke oven plant our oven fans extract the raw Coke Oven Gas (COG), a by-product of the coke production, and provides a very important source of high calorific gas which is then used as a fuel gas in other parts of the steelmaking process.

Whether using the straight grate process or adding a rotary kiln to make the grate-kiln process, our products play a key role. To dry and heat the ore pellets, a number of fans are used to recycle heat from the kiln. After indurating in the kiln, cooling fans are used to cool the pellets for handling downstream, and fans are used to facilitate dust handling. Our Tail End SCR rotary gas-gas heaters are being used in the emissions reduction systems of pelletising plants to efficiently transfer heat between the treated and untreated gases.

Shaft furnace: Rotary blowers and centrifugal compressors are used in the process to supply combustion air into the reformers and a process gas compressor, seal gas compressor, and a cooling gas compressor are required to help circulate the process gas.

Rotary kiln furnace: Combustion air is supplied into the combustion chamber by a forced draught fan. The waste gases are utilised to heat a boiler, and a waste gas induced draught fan draws the hot gases through the waste gas boiler and electrostatic participator before releasing them to the atmosphere.

Howden products are used in numerous other applications:
