Premixed combustion of coke oven gas in a metallic fibre mat

Combustion characteristics of liquefied petroleum gas (LPG) and coke oven gas (COG) in a metallic fibre mat were investigated experimentally to examine the effect of fuel change on surface combustion performance. It was found that the upper limit of surface loads representing the radiant mode is increased in the case of COG combustion. Mat temperatures were slightly lowered for COG combustion at low surface loads. The surface load showing the maximum surface temperature was shifted to a higher one for COG combustion. It was concluded that the range of surface loads for radiant mode combustion and the surface load for the peak surface temperature are mainly dependent upon the flame speed of the fuel used.
