Aiming at the thermal calculation of supercritical boiler furnace check, the article is based on the divisional calculation method in the thermal calculation standard of the Soviet Union in 1973, combined with the 1-D block flow model of pulverized coal combustion, and proposes a new divisional 1-D furnace exchange thermal calculation model, and compiled the corresponding thermal calculation software. The software is easy to use, not only can obtain the average temperature distribution of flue gas along the height of the furnace and the heat load of the section water wall, but also the carbon content of fly ash. The article takes a 600 MW supercritical boiler as an example and uses software to calculate the heat transfer in the furnace.

The relevance of the study is due to low effective utilization of heat of fuel combustion in existing heat generators, in particular, boiler units intended for heat supply to industrial enterprises and residential buildings. Another important research area of the study is the ascertaining ability of a boiler to operate on raw water, which hasn’t undergone a process of preliminary reduction of hardness. The article reveals the use of latent heat of water vapor contained in the exhaust gases in all models of existing boiler units. The authors proposed and described a method for the effective utilization of the latent heat by means of contact heating of the coolant.
