LOW NOx PULVERIZED SOLID FUEL COMBUSTION PROCESS AND APPARATUS

摘要

A method and apparatus for low-NOx combustion of a pulverized solid fuel in which combustion products from a partial oxidation combustor (11) are mixed with a pulverized solid fuel, thereby preheating the pulverized solid fuel and resulting in devolatilization of at least a portion of the pulverized solid fuel. The preheated pulverized solid fuel and the devolatilization products are then burned in a burner (5) firing directly into a combustion chamber (14).
