Sulfation of corrosive alkali chlorides by ammonium sulfate in a biomass fired CFB boiler. IntroductionHigh temperature corrosion causes expensive shutdowns and repairs for the owners of heat and power plants. Fuels with high chlorine content such as municipal solid waste or some biomass derived fuels tend to aggravate corrosion by elevating alkali chloride concentrations in the flue gas.

Corrosion in the Flue Gas Cleaning System of a Biomass

only biomass has been used in the boiler. The flue gas flow through the flue gas cleaning system (FGCS) is shown in Figure 1. The flue gas is led through the flue gas desulphurisation unit (FGD) where the majority of sulphur and chlorine species are removed. After that it is led through the gas/gas heat exchanger (GGH)

Sulfation of corrosive alkali chlorides by ammonium

01/12/2007 · IACM measures the concentrations of alkali chlorides (mainly KCl in biomass combustion) at superheater temperatures. Tests with and without spraying ammonium sulfate into the flue gases have been performed in a 96MWth /25MW e circulating fluidized bed (CFB) boiler. The boiler was fired mainly with bark and a chlorine containing waste.
