An Investigation of Radiant Heat Exchange in Boiler

Abstract

There has been no satisfactory method to obtain the distribution of radiant heat on water-cooled surfaces of a boiler furnace. This distribution may depend heavily upon the flow pattern of burning gas. From this point of view, the present paper relates to a method of defining the distribution of gas temperature and radiant heat by estimating the flow pattern in a furnace, leaving aside a number of unknown factors of combustion and thermal characters of burned gas. Result of the present calculation for a gas burning boiler whose distribution of radiant heat was measured by Mumford and Corey gives a good qualitative agreement with their measurement.
