Accordingly, in this
paper the effect of co-combustion of coal and some chosen
renewable fuels of biomass and agromass origin is investigated
with particular attention put to the assessment of the effect of
biomass or agromass type on solids accumulation on P91 steel tube
samples. The P91 or X10CrMoVNb9-1 steel ([17]) is martensitic
quenched and tempered alloy steel used in modern power boilers
to manufacture the tubes of steam final superheaters. Due to special
