Recovery Boiler SCR - Retrofit challenge and opportunity

2018-3-14·In recovery boiler retrofit cases there are three challenges for SCR: SCR reactor inlet flue gas temperature, probable SO2 in the flue gas and excess particulate concentration after the electrostatic precipitator. Flue gas temperature should be ~250 °C and SO 2 preferably below 5 mg/m3 to avoid formation of harmful ammonium bisulfate.

Practically a boilers is a set of heat exchangers, which are transferring the fuel combustion heat from the boiler furnace to a heat-transfer agent. Fuel is fired in the boiler furnace and the hot gases move through gas pass formed by special heat exchangers. The first is a superheater, where steam is heated up to 560 at a pressure of up to

Effect of wet flue gas desulfurization (WFGD) on fine

The flue gas desulfurization process could generate a large number of particulate matters (Bao et al., 2009). These aerosol particles formed during desulfurization can easily escape from the demister and enter the atmosphere. The addition of a desulfurization agent (e.g., limestone, caustic soda) could also greatly change the PM 2.5 components
