The article presents the results of a computational and theoretical analysis of the performance of the solid fuel boiler unit intended for wood chips combustion, the input fuel moisture content being of 10% to 50%. The authors consider the main design features of the solid fuel boiler unit equipped with a shielded furnace and fire-tube two-pass convective heating surfaces without turbulent movement intensifiers of combustion products. The influence of changes in the moisture content and the operating modes of the boiler unit on the main balance and operating values responsible for the thermal efficiency and economy of the boiler is analyzed.
