Abstract
The paper analyzes the influence of humidity of combusted wood biomass on
the flue gas losses. A mathematical relation between flue gas losses of
the boiler on wood biomass humidity is presented as well as temperature of
flue gas emitted from the boiler into the atmosphere. The limits of model
application for the humidity of wood biomass falls into the interval
10–60% whereas the range of temperatures of flue gases emitted from the
boiler to the atmosphere is 120–200°C. The influence of the humidity of
wood biomass has an adverse effect on increasing the extent of the boiler
flue gas losses and thus inefficiency of the heat production. The increase
of the wood biomass humidity from the value of 10% to 60% with the outlet
temperature of flue gases from the boiler 120°C causes an increase in flue
gas loss of the boiler from the value 8.37% to 12.43%, similarly the
increase of flue gas loss by 200°C from 15.19% to 22.55%, or the increase
of the flue gas loss by 7.36%.
