The surface heat and mass balance
WebFeb 2, 2011 · 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 … http://ocean.stanford.edu/courses/bomc/chem/lecture_06.pdf
