  • Air Pollution Control Technology Fact Sheet

    boiler operating at 85% capacity requires approximately 17 m 3 ( 600 ft 3). For the same sized coal-fired boiler, the required catalyst is on the order of 42 m3 (1,500 ft3). (NESCAUM 2000). SCR is a proprietary technology and designs on large combustion units are site specific. Retrofit of SCR on an existing unit can increase costs by over 30% Get Price

  • Nitrogen Oxides: Pollution Prevention and Control

    using the flue gas from the economizer outlet, both the furnace air temperature and the furnace oxygen concentration can be reduced. However, in retrofits FGR can be very expensive. Flue gas recirculation is typically applied to oil- and gas-fired boilers and reduces NO x emissions by 20– 50%. Modifications to the boiler in the form ofGet Price

  • 1.1 Bituminous And Subbituminous Coal Combustion

    reduction varies considerably depending on boiler type, fuel, and boiler operation. Soot blowing is also a source of intermittent PM emissions in coal-fired boilers. Steam soot and air soot blowing is periodically used to dislodge ash from heat transfer surfaces in the furnace, convective section, economizer, and air preheater.Get Price

  • Steam-electric power station - Wikipedia

    The boiler transfers energy to the water by the chemical reaction of burning some type of fuel. The water enters the boiler through a section in the convection pass called the economizer. From the economizer, it passes to the steam drum, from where it goes down the downcomers to the lower inlet water wall headers.Get Price
