3 DIMENSION RADIATION HEAT TRANSFER ANALYSIS METHOD IN BOILER FURNACE

摘要

In order to facilitate the three-dimensional radiant heat transfer analysis in the boiler furnace, the control volume is inputted by the combustion analysis step of calculating heat and mass balance according to the first law of thermothermal, and the average temperature and average density obtained in the combustion analysis step as inputs. Three-dimensional flow in the boiler furnace comprising a flow analysis step of dividing the area elements and space elements of the axial direction into a plurality of directions, and a radiant heat transfer analysis step of summing the results obtained in the flow analysis step in each face to use the flow rate conditions Using the radiant heat transfer analysis method, the three-dimensional radiant heat transfer phenomenon can be analyzed relatively simply.
