Title:
COMBUSTION DEVICE
Document Type and Number:
Japanese Patent JP3189728
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To expand a ratio between a combustion amount before changing-over operation and a combustion amount after changing-over operation in a combustion device of which amount of combustion is clanged over into more than two kinds of different amounts of combustion by a method wherein there are provided at least two fuel nozzles and these fuel nozzles are selectively operated.
SOLUTION: When an amount of combustion is changed over, a fuel nozzle being operated before changing-over operation and another fuel nozzle operated after changing-over operation are operated concurrently for a specified period of time and then an amount of injection of fuel injected from at least one fuel nozzle is decreased within this specified period of time. Further, a fuel nozzle 4 is connected to a fuel supplying line 5 and return line 10, a flow rate in the return line 10 is controlled by a flow rate control means 11, thereby the amount of injection of fuel is adjusted and further the combustion device 1 is provided with at least one fixed fuel nozzle 3.
