Title:
FUEL LANCE FOR LIQUID AND/OR GASEOUS FUEL AND METHOD FOR OPERATION THEREOF
Document Type and Number:
Japanese Patent JP3672597
Kind Code:
B2
Abstract:
PURPOSE: To enhance combustion efficiency while reducing emission of harmful components by providing an appropriate nozzle and a cooling air supply unit surrounding a lance like an outer shell and cooling the lance and fuel with cooling air thereby preventing early firing.
CONSTITUTION: A fuel lance for use in a combustion chamber defined by the casing of a gas turbine includes a liquid fuel pipe 7 surrounded by an elongated lance outer shell 11 and secured to the easing by a holding arm projecting sideways, a gas pipe 9 forming a gas passage around the liquid fuel pipe 7, and the lance outer shell 11 forming an air passage 10 around the gas pipe 9. An air/fuel nozzle 12 is provided on the side at the downstream end part of the fuel lance, a gas pipe 9 is provided with a gas nozzle 15 for ejecting gas from a gas passage 8 together with air, and the liquid fuel pipe 7 is provided with a liquid fuel nozzle 18 for ejecting liquid fuel through the air passage 10 and the air/fuel nozzle 12.
