  • Section 4 NO Controls x - US EPA

    SCR capital costs vary by the type of unit controlled and the fuel source. Capital costs for retrofit of coal-fired electric utility boilers range from 50 1 to 702 dollars per kilowatt ($/kW) for wall- and tangential-fired boilers and 50 1 to 80 1 $/kW for cyclone and wet bottom boilers. New utility boiler capital costs are generally less than Learn More

  • Fly ash - Wikipedia

    Fly ash or flue ash, coal ash, and also known as pulverised fuel ash in the United Kingdom, or coal combustion residuals (CCRs), is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases.Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is Learn More

    monoxide. Some boiler owners may be granted a one-year extension delaying the compliance date until January 31, 2017. Within 180 days of the compliance date, industrial boiler operators must demonstrate compliance. The EPA estimates that approximately 600 coal-fired boilers will be affected by the IB MACT in industries such as pulp and paper.Learn More

    Mar 16, 2021 · Mar 16, 2021 · Combustion technologies vary in coal-fired utility boilers. Each achieves a different level of fuel efficiency, measured as the amount of coal needed to produce the same amount of electricity. The least efficient boilers in operation today are aging subcritical units that convert less than 35% of coal energy into electricity.Learn More

  • Chapter 2 Selective Catalytic Reduction

    The procedures for estimating costs presented in this report are based on cost data for SCR retrofits on existing coal-, oil-, and gas-fired boilers for electric generating units larger than 25 MWe (approximately 250 MMBtu/hr). Thus, this report's procedure estimates costs for typical retrofits of such boilers.Learn More
