Sulfation of corrosive alkali chlorides by ammonium …

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 96MW (th)/25MW (e) circulating fluidized bed (CFB) boiler. The boiler was fired mainly with bark and a chlorine containing waste.

Fouling in coal-fired boilers: Biomass co-firing, full …

As coal-fired boilers in The Netherlands are considered to be converted to high biomass co-firing or pure biomass boilers, issues with fouling by alkali salts are expected. The behaviour of gaseous alkalis is different in converted coal boilers than in dedicated biomass boilers due to the higher firing temperature.

Typical Causes of Slagging and Fouling Problems in Boilers

Compared to boilers fired with coal and oil the biomass-fired boilers have more complications related to both fouling and corrosion on the heat transfer surfaces. After the combustion, unburned inorganic matter in state of vapour, melts and solid particles are transported in the flue gas and may form deposits on heat transfer surfaces.
