Abstract
Air pollution from combustion of air/gas mixtures is reduced effectively and reliably at a porous burner providing flames with a downstream reaction zone where the ignition of the air/gas mixture initiates. The porous burner is loaded with the air/gas mixture sufficiently, such as at from 1000 to 2500 kWm.sup.-2 or 2200 to 5500 Btu/sqin-hr, to locate the downstream reaction zone at a downstream surface of the porous burner, while the air/gas mixture is provided with sufficient excess air, such as more than a quarter of excess air, for the flames to burn blue. In a typical combustion of that air/gas mixture, less than 20 ppm of NO.sub.x are produced. A related method loads the porous burner with the air/gas mixture at from 1000 to 2000 kWm.sup.-2 or 2200 to 4400 Btu/sqin-hr, while providing that air/gas mixture with more than about forty-five percent of excess air for the flames to burn blue. That combustion of the air/gas mixture including its excess air produces less than 10 ppm of NO.sub.x.
