Deposition and high temperature corrosion in a 10 MW straw fired boiler
Especially, straw fired boilers have been experiencing problems due to the inorganic metal constituents such as alkali metals and chlorine present in the straw. A demand to raise the temperature of the superheated steam to improve the electrical efficiency and to make the plants more economically feasible has been an area of discussion especially with regards to corrosion of the superheater tubes.

The corrosion of superheater tube material in straw-fired boilers was investigated in the laboratory. Metal test elements of boiler tube steel (X20CRMV121 and AISI 347FG) were covered with synthetic (KCl and/or K 2 SO 4) and real deposits, and exposed to a synthetic flue gas (6 vol % O 2, 12 vol % CO 2, 400 ppmv HCl, 60 ppmv SO 2, balance N 2) in 550 C electrically heated ovens.
