Development and application of thermal calculation software for boiler furnace

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.
