LOW-NOx COMBUSTOR FOR GAS TURBINE

摘要

PROBLEM TO BE SOLVED: To provide a low NOx combustor for gas turbine which can stably burn sludge digestive gas which is low in calorific value and is high in content of inert gas, and besides can reduce the quantity of occurrence of NOx.;SOLUTION: This low-NOx combustor is equipped with a pilot burner 12 arranged at the center and a plurality of main burners 14 arranged around it. The pilot burner is a diffusing burner which diffuses and combust fuel (for example, sludge digestive gas) within a combustion chamber 11, and the main burner is a premixing burner which premixes fuel and air and combust them within the combustion chamber. The premixing burner has a premixing pipe 15 which premixes fuel and air and a swirler 16 which is provided between the premixing pipe and the combustion chamber.;COPYRIGHT: (C)2002,JPO
