ABSTRACT
The higher amount of flue gases means a lower tem-
perature in the boiler, as reflected in the adiabatic
combustion temperature.
In the case of 65% moisture content, the adiabatic
combustion temperature is so low that preheating of
the combustion air would be necessary to ensure
complete combustion. The combined influence of
increased flue-gas volumes and decreased temperature
level means that a larger and more expensive boiler
is required when firing a fuel with higher moisture
content.
