Optimizing every stage of the power generating process with efficient, reliable solutions
Howden fans, rotary heat exchangers and compressors operate at peak performance for years between planned outages.
The advanced technology and inherent reliability of our fans and rotary heat exchangers, combined with our comprehensive lifetime support, provides you with unrivalled value. Howden has supplied over 40,000 boiler draught fans, almost 5,000 rotary heat exchangers, and over 100,000 cooling fans in more then100 countries, making us the leading supplier to the industry.
Every Howden product is backed by an absolute commitment to lifetime support and service that covers all spare parts, troubleshooting, scheduled maintenance and emergency response. We are dedicated to maintaining your plant at peak performance and, above all, keeping it in continuous production.
Howden are process specialists in a range of applications whether it be conventional boilers (coal, oil or gas fired) or circulating fluidized bed boilers (CFB) utilizing fossil fuels or biomass. We offer fly ash and multi-pollutant control systems as well as dust cleaning (particulates) and air cooled condensers and cooling towers.
One of the most valuable advantages in working with Howden is that you can discuss your requirements with engineers who have a detailed understanding of the workings of power generating plants. You invest in a continuing partnership that gives you unrivalled global expertise in air and gas handling processes.
Forced draught fans move ambient air at low pressure through the air preheater to provide heated oxygen for the combustion process.
Induced draught fans are vital in maintaining furnace pressure at just below atmospheric pressure. They draw the ﬂue gases out of the boiler into the air preheater.
Primary air fans are used to move air through the air preheater in coal and biomass fuelled stations. The size and conﬁguration of the fan depends on the temperature of the primary air.
Secondary air fans feed into the boiler combustion chamber at a higher point than the primary air to promote more complete combustion.
Cooling fans are used to condense steam into water and help to increase the pressure difference over the steam turbine.
Air preheaters are used to recover heat from ﬂue gases and use it to raise the temperature of air entering the combustion chamber.
Howden’s ExVel turbo fan has been developed speciﬁcally for Mechanical Vapour Compression – an advanced and efﬁcient process to be used also in zero liquid discharge (ZLD) application to fulﬁll expectations for environmentally friendly power plant - recycling the vapour during the evaporation process to re-use the energy it contains.
Gas gas heaters are used to reheat the gas in ﬂue gas desulphurisation plants and SCR systems.
Gas recirculation fans help control furnace gas or steam temperature by re-circulating ﬂue gas through a dust collector and back into a particular area of the combustion chamber.
Flue Gas Desulphurisation (FGD) or Selective Catalytic Reduction (SCR) Booster fans help to drive the ﬂue gas through cleaning processes before it is released from the station.
Oxidation air blowers are associated with the cleaning of ﬂue gases in a Flue Gas Desulphurisation (FGD) by supplying air into absorber or spray tower.
Blowers providing ﬂuidising air within the loop seal system on a circulating ﬂuidised bed (CFB) boiler.
Our lifelong aftercare service will supply original replacement parts, support you with maintenance and installation, and even train your own engineers in maintenance techniques. We keep detailed plant records almost indefinitely, and regularly supply spare parts for machinery over 50 years old.
