COMPUTATIONAL ANALYSIS OF LOCAL HEAT-RELEASE RATE OF WATER-WALL TUBE IN REACTION TUBE FURNACES

摘要

A method is proposed, and local thermal fluxes around the circumference of water-wall tubes in tube furnaces are analyzed. The method is based on the zonal approach to description of radiational and complex heat exchange and statistical modeling of radiation for the purpose of determining local generalized slopes. The method of calculation and results of analysis of the local heat-release rate of tubes in reaction furnaces with double-daylight one- and two-tier tube water walls assume scientific and practical significance for design of this type of equipment.
