Abstract
Primary air entrainment for an atmospheric gas burner has been theoretically correlated with design and operation parameters, taking the temperature effect into consideration. The theoretical entrainment correlation has been compared with experimental data obtained from a fish-tail burner (in which errors in temperature measurement could be eliminated).
The results calculated from the correlation equation showed practically satisfactory agreement with the experiments, including the influences of gas-air mixture temperature, burner port area, gas density, gas flow rate and gas pressure.
