Cost Information: Capital costs are significantly higher than other types of NOx controls due to the large volume of catalyst that is required. The cost of ca talyst is approximately 10,000 $/m 3 (283 $/ft 3). A 350 MMBtu/hr natural gas-fired boiler operating at 85% capacity requires approximately 17 m 3 ( 600 ft 3). For the same sized coal

Read MoreAn electric generating technology in which electricity is produced from otherwise lost waste heat exiting from one or more gas (combustion) turbines. The heat is routed to a conventional boiler or to a heat recovery steam generator for use by a steam turbine in the production of electricity.

Read MoreHigh-dust arrangement (HD): The SCR unit is positioned immediately after the boiler. This configuration is used mostly in coal-fired applications, because the gas flue temperature at this location (300 - 400°C) is optimal for the catalyst activity. Dust removal is typically accomplished in cold electrostatic precipitators downstream of the SCR
