Method for low NOx combustion with low pressure drop - U.S. Patent 20090293446
U.S. Patent 20090293446, issued 2009.
Abstract
The present invention provides a method for the reduction of pressure drop in low NOx combustion of fuel and air, maximizing energy efficiency. A supply of fuel and a supply of air form a fuel rich mixture that is reacted to produce partial reaction products and heat. A portion of the heat is transferred to a second supply of air. The partial reaction products are mixed with heated air and with a third supply of air to form a fuel lean admixture that is passed to a combustion zone for low NOx combustion.
