Calculation analysis of zonal and local resulting heat transfer in combustion chamber of tube furnaces

A numerical method of calculation of the local resulting characteristics of radiative-convective heat transfer in the framework of the zoning approach is developed for application to the analysis of combustion chambers with water walls of technological tube furnaces. On this basis, a methodology for calculating local heat fluxes along the perimeter of water wall tubes is developed. Approbation of the calculation technique was carried out.
