Howden and Chart equipment supports the decarbonization of the metals industry with our Green Steel solutions. Our products remain integral to traditional processes such as coking and sintering, furnaces, pelletization and steelmaking as well as non-ferrous metals processing.
Whether pursuing low carbon production or maintaining existing processes our fans, blowers and compressors can all be tailored to your application. Our heaters contribute to efficient emission controls and Chart solutions provide wider access to hydrogen related production and carbon capture.
As the steel industry aims at decarbonization, green steelmaking processes by using low carbon technologies and renewable energy will accelerate.
Howden and Chart are uniquely positioned to equip the steel industry’s decarbonization having a comprehensive suite of engineered products across the whole green steel value chain, particularly when the Direct Reduced Iron (DRI) process is used.
We are actively working with industry pioneers to develop greener solutions with our projects supplying compression into green steel DRI process plants, the hydrogen plants feeding steel production as well as hydrogen storage systems.
The DRI approach removed the need for fossil fuel coke processes and can replace natural gas with renewable hydrogen as a fuel source.
Howden's single stage and multistage integrally geared compressors are used in various DRI applications to handle process gas as well as main air. Our screw compressors provide oil free compression for pneumatic transfer and our fans can be found moving gas and air for a wide variety of applications throughout the central process and supporting emissions treatment and service plants.
Applicable products:
As Green Steel takes advantage of lower carbon gas sources or hydrogen within the process, storage systems are critical. Chart Vacuum Technology® is at the core of Chart’s position as the premier supplier of cryogenic equipment combining with Chart’s regasification systems for a full end-to-end solution.
If the plant is integrated with the hydrogen production, Chart's technology covers feed water treatment to electrolysers to liquefaction, complimented by Howden's hydrogen compressors to feed the plant directly or as part of the regasification process.
Applicable products:The conventional steel making process uses a blast furnace to convert iron ore into pig iron, a precursor to steel. Howden equipment is used throughout the process from raw material processing and the blast furnace section to steel making, handling necessary air supply and gases.
PelletisingThe pelletizing of iron ore is an initial point in the whole process. 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.
CokingTo fuel the furnace, coke is produced in oven batteries. Our fans provide the combustion air to the furnace. They also draw waste gas through the FGD plant, where our rotary heaters assist the performance efficiency by transferring heat from the gas.
The coke-oven gases containing hydrogen, methane and carbon monoxide, are removed from the plant by exhausters - centrifugal blowers/compressors supplied by Howden. This gas mixture has a value and can be processed further. Firstly cooled, where our screw compressors are integral to mechanical refrigeration systems and then boosted by our compressors to users or storage.
SinteringIn 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. Waste gas is treated at the tail end of the process in an SCR, where our rotary heaters boost the efficiency of the system by transferring heat from the gas to the process stream.
Blast FurnaceThe 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.
Steel MakingHowden 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.
Applicable products/services:
Non-ferrous metals, such as Copper, Aluminium, Zinc and Nickel, are a key component in many industrial and technology based manufactured products currently see rising demand. The production processes are energy intensive and so production equipment must contribute to goals to lessen environmental impact and increase efficiencies.
Howden products are there at the start, used within underground mines for ventilation (see mining). When it comes to the processing stages, multiple methods are used, which involve Howden's air and gas handling technology.
AluminiumPrimary aluminium manufacture is accomplished involves refining bauxite ore to obtain aluminium oxide (Bayer process) and smelting the aluminium oxide to release pure aluminium (Hall-Heroult process).
Our MVR compression expertise is supporting efficiency within Alumina refining. Our fans are deployed within the calcination process for primary air and flue gas exhaust as well as in smelting as part of the fluidization system.
CopperHowden equipment is found mainly in the pyrometallurgical process based on sulfide ores.
Our centrifugal blowers/compressors supply air or oxygen to assist combustion within the smelter. Sulphuric acid is a by-product of the smelting process. After the waste gas is cleaned in the Sulphuric Acid Plant (SAP), the SO2 is dried in a Drying Tower, which is then typically followed by the SO2 main blower. Centrifugal compressors/blowers are the typical design choice and can be supplied with electric motor or steam turbine driven.
During the conversion process, our blowers provide blast air to be blown through the tuyeres, into the molten bath. Sometime these are steam turbine driven, which we can supply separately or as an integrated unit.
Within the hydrometallurgical process, our centrifugal fans can be found providing aeration within heap leaching pads.
Nickel/Zinc/LeadAcross the various processes, Howden compressors, blowers, and fans play a role providing combustion air for smelting, air for calcination and sintering, and for flotation. Where Sulphuric Acid production is present, our blowers are relied upon to handle SO2.
