Abstract
Remarkable suppression of the formation of pollutants: NO.sub.x, CO and UHC, in the flameless combustion of gaseous fuel with excess air is achieved by passing the fuel and air through a porous surface combustor directly into an adiabatic zone, and by controlling the amount of excess air to be greater than about 50% but not greater than about 150% in excess of the stoichiometric requirement. The furnace with the adiabatic zone for the suppression of pollutants will preferably have a refractory body as part of the adiabatic zone.
