Common Boiler Feedwater Treatment Issues and Ho

The higher the boiler pressures, the more severe the corrosion. When chlorides are present at an unacceptable level, chloride stress cracking can also occur. Corrosion typically occurs in the parts of the boiler that are heated the most, where high temperatures and cracking in the metals accelerate the breakdown of the materials.

Biomas co-firing in a CFB boil

The aim of present paper is to investigate the effects on gas distribution in a CFB furnace from burning varied fractions of wood fuel with coal as a base fuel. The work is based on in-situ measurements of gas concentrations at different locations in the furnace of the Chalmers 12 MWth CFB boiler. The boiler was operated at two different pressure drops over the furnace, corresponding to
