Determination of coefficients of heat output of hot-blast stove checkers with horizontal passages
Journal Title: Metallurgical and Mining Industry - Year 2017, Vol 9, Issue 3
Abstract
The benefits and results of physical modeling of new design of block checkers with horizontal passages are shown in the paper. They are developed by fellows of department of Ecology, Heat- Transfer and Labour Protection of National Metallurgical Academy of Ukraine in cooperation with Zaporozhogneupor PJSC. The main objective of experimental study was to determine the convection heat transfer coefficient and gasdynamic resistance of checker, as its main thermal characteristics. Dependences for determination of coefficients of convection heat transfer were defined from the obtained ratios of similarity criteria Nu = f (Re) for the rough continuous channel, vertical channels with two and three horizontal passages, and also the checker block with horizontal passages.
