Determining the range of variation of convective heat transfer coefficient during the combustion of alternative kinds of gaseous fuels

Abstract

The article highlights the reason of complication of usage of alternative fuel gases on the installed equipment — the organization of effective process of their combustion. As one of the parameters affecting the dynamic characteristics of the control object, the coefficient of convective heat transfer is considered. The effect of changes of physical characteristics of heat and rate of combustion products arising from the use of various combustible gases on it is determined. It is found that the main cause of the change of heat transfer coefficient is the presence of flammable gases of carbon monoxide and hydrogen in the mixture.
