ABSTRACT:
A process for combustion of the combustible material includes introducing the combustible material into the combustion chamber, advancing the combustible material through the combustion chamber, supplying combustion air to the combustion chamber for drying and partially combusting the combustible material and final ash burnout in a primary combustion zone, and removing ash products from the combustion chamber. The fuel or fuel/carrier fluid mixture is supplied into the combustion chamber to create an oxygen deficient secondary combustion zone for NO.sub.x reduction and other nitrogen bearing compounds decomposition. An oxidizing fluid is supplied into the combustion chamber above the oxygen deficient secondary combustion zone for thorough mixing with combustion products and at least partial burnout of combustibles in an oxidizing tertiary combustion zone. A furnace for combustion in accordance with this process is also disclosed wherein a combustion chamber is configured such that combustible material can be advanced from a drying zone, to a combustion zone, to a burnout zone, and then into an ash pit. An air source provides air for drying, combustion and burnout in a primary combustion zone. Fuel or a fuel/carrier fluid mixture is injected above the primary combustion zone to create an oxygen deficient secondary combustion zone, to reduce NO.sub.x and decompose other nitrogen bearing compounds entering the secondary combustion zone. An oxidizing fluid is injected into the combustion chamber above the oxygen deficient secondary combustion zone.
