Our equipment supports core processes such as coking and sintering, furnaces, palletization and steelmaking as well as utilities, playing an integral role in most metal processing plants including flue gas treatment, wastewater treatment, process cooling, waste heat recovery systems and more.
If air and gas need to be moved, or compressed, at any process location within a metals plant Howden have a solution for you, ranging from fans, turbo-blowers and compressors that can all be tailored to your application. Our regenerative heaters transfer energy from and to a gas flow source when air and gases need to be heated or cooled for plant efficiency or emissions reductions reasons.
Providing and recovering gas in the coke oven plant and sinter machine
In the coke oven plant our oven fans provide the combustion air to burn the coke (mostly carbon).
Howden centrifugal compressors in the coke-oven by-product plant exhausters remove the by products such as sulfur, phenol and ammonia. Our rotary Gas Gas Heaters are being used in the emissions reduction systems of sinter plants and coke plants to efficiently transfer heat between the untreated and treated gases.
In the sinter plant our forced draught combustion air fans support the combustion process before our cooling fans are used to cool the product. Hot air is recovered and returned to the process and dust is controlled using specialist Howden fans.
Directing heated and cooled air where it is needed and recycling heat to save energy
Whether using the straight grate process or adding a rotary kiln to make the grate-kiln process, our products are key to the process. 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.
Fans and blowers designed to facilitate the production of molten iron
The Blast Furnace is designed to reduce iron oxides and to separate the resulting iron from the large quantities of impurities in the ore. Blast furnace fans are essential to drive heated air into the furnace and our ID fans are then used to draw the furnace gases. Where a cooling tower exists, our cooling fans are an important way to remove heat.
Shaft furnace: 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 throughout the steelmaking process: Induced draught waste-gas fan or basic oxygen steelmaking (BOS) fan for dust control, Dust removal system and wet scrubbers for cleaning the gas, cooler exhaust fans are used to cool the off gases, main induced draught waste gas fans are used for more dust removal, and vacuum boosters are important in the vacuum degassing process.
