In the present study the common ferritic and austenitic steels (2.25Cr1Mo, X10, X20, TP347H, AC66, Sanicro28, Esshete 1250) usually used in biomass and waste combustion processes were investigated. The multi-sample exposure tests were carried out at

Sulphidation attack of the heat transfer surfaces in boilers may be due to the presence of reduced sulphur compounds in gaseous phase, or due to the result of adverse deposit conditions. Under reducing conditions in the furnace, the safe upper temper

In order to increase the steam parameters in combustion units, several new approaches have been proposed. New materials have been tested, but they seldom have been a sufficient solution. Metallic coatings sprayed on superheater tubes have been noted
