CALCULATIONS OF HEAT TRANSFER IN TORCH FURNACES
Anatoliy Makarov
|
Abstract: Heat transfer by radiation is the main type of heat transfer in electric arc steelmaking and torch furnaces, fire boxes, combustion chambers and is 90-98 % of the total heat transfer in furnaces, fire boxes, and combustion chambers. The geometrical, physical model of electric arcs and torches of furnaces, fire boxes, combustion chambers are developed. The results of calculation of heat transfer in furnaces using the developed model of the torch are presented. The error of calculations does not exceed 10%. The performed calculations using the developed model of the torch allowed to reveal uneven heating of products and to develop innovative torch furnaces, in which the heat flows are aligned on the heating surfaces, the heating time and fuel consumption are reduced. |
Keywords and phrases: heat transfer, torch, gas radiating volume, furnace, heating, scientific discovery.
