Abstract
In this work, the emissivity charts of seven fuel gases were presented. Fuel gases had similar behaviour in general, meaning that the total emissivity of each increased until a certain temperature and then it decreased. For the studied gases, the maximum emissivities were observed between T =500K and 800K. In addition, total emissivities increased by increasing pL values due to the higher concentration of the fuel gas molecules. However, the total emissivities were independent of pL at pL > 5 atm.m.
