Abstract

Abstract-

Laws of heat radiation from spherical gas volumes. Part II. Modeling of heat radiation from volume bodies by radiation from spherical and cylindrical gas volumes

“…Thus, gas volume in the form of parallelepiped can be modeled by cylindrical gas volume, one-two hundred spherical gas volumes and obtain the results from calculations with high accuracy. The torch is used in heating furnaces, fire boxes, steam boiler boxes and combustion chambers of gas -turbine power plants [1][2][3][4]. Torch, created by a single burner, is an ellipsoid of revolution, which burns the fuel, supplied to the burner [1][2][3][4].…”

“…The torch is used in heating furnaces, fire boxes, steam boiler boxes and combustion chambers of gas -turbine power plants [1][2][3][4]. Torch, created by a single burner, is an ellipsoid of revolution, which burns the fuel, supplied to the burner [1][2][3][4]. Torch length is the distance from the burner, at which at least 98% of the fuel is burnt.…”

“…To calculate heat radiation from torch on the heating surfaces , it is necessary to solve triple integral equations , describing volume radiation from torch. In the 20th century the solution for triple integral equations in the form of analytical expressions, formulas was not found [1]. However, the disclosure in the late 20th century of the laws for heat radiation from cylindrical and spherical gas volumes, laws of Makarov and the methods for calculation, developed on their basis , allow to simulate the torch by a set of cylindrical and spherical gas volumes and calculate the fluxes of the heat radiation incident on the heating surface from the torch [1][2][3][4].…”

The developed method of heat transfer in torch furnaces allows to calculate the rational fuel consumption, the location of the burners and the rational parameters of the torch: length, power and its distribution over the length , the spatial position in the furnace, the angle of torch.…”
