Gas-tube boilers: Issues of classification and thermal calculation

Abstract

The characteristics of the structure of small boilers are considered. The methods of calculation of heat transfer in the furnace are analyzed. Directions for further development of heat transfer calculation during fuel combustion of are formulated and the ways to solve them are offered. The focus is on the numerical approach for the solution of known differential equations of heat transfer and hydrofluid dynamics. The results of the comparison of the calculated and literature data are presented.
