FURNACES - A-to-Z Guide to Thermodynamics, Heat

In most process heaters, the major part of the heat transfer from the hot gases to the tubes is by radiation. To calculate the radiative component it is necessary to know the effective emissivity, ε g, of the combustion gases (typical value 0.25).This is dependent on the ratio of the partial pressures of CO 2 and H 2, the temperatures of the gas and the radiation source and the effective size
