Abstract

A gun-type burne. fur a LPG(Liquified Petroleum Gas) boiler was utilized for hydrogen combustion. The study was performed to obtain fundamental data prior to the design of a very low NO$\_$x/, hydrogen-fueled burner. First, numerical simulations were performed to predict mixing characteristics between air and fuel flows, and temperature distributions, etc. Experimental study was then performed to find out flame lengths, temperature distributions, and NO$\_$x/ concentrations. The results showed that a gun-type burner for a LPG boiler can be successfully used for hydrogen combustion without any major retrofitting. The hydrogen flame was very stable and 75 ppm of NO$\_$x/ in average was observed for the conditions considered in this study. Hydrogen combustion could be therefore a solution to avoid the problem of green-house gas(CO$_2$) if hydrogen becomes cost-effective.
