For low-calorific gas gas turbine combustor

摘要

PURPOSE: To provide a means which supplies nitrogen and continue combustion efficiently. ;CONSTITUTION: In a gas turbine combustor for low calorie gas which burns low calorie gas fuel, a low calorie gas opening 4, an air opening 5, and a nitrogen opening 6 are provided in a fuel injection nozzle 2 to dilute low calorie gas and air to be supplied with nitrogen so that heating value of gas is reduced, oxygen concentration of air is reduced, temperature of flame at the time of combustion is kept low, and producing amount of NOx is reduced.;COPYRIGHT: (C)1996,JPO
