Abstract: An original method the geometric modeling of the thermal balance between the combustion and convective parts of a low-power heat-tube unit is proposed, which allows to perform a thermal calculation by adjusting the location of the burner in the combustion part of the boiler to achieve the required power and maximum efficiency when using fuels with different degrees of heat combustion. The basis on this calculation is the allocation of 4-h volumes (zones) of the combustion products in the combustion part of the heat unit. In the first (main) and second (end) zones in the dead-end furnace is always accumulated half of the total heat of combustion (geometrically it is a heat trap). The third zone provides the optimal coefficient of integral transfer (adjustment) in the combustion part, as well as the power and efficiency of the heat unit. The fourth zone determines the residual power and efficiency achieved in the convective part of the heat unit.

Keywords: the integrated transfer coefficient, thermal balance, fire-tube heat unit, convective portion, furnace, the core of the torch, the heat combustion of fuel, area of heat transfer.
