Abstract

The invention relates to a multi-head dual fuel combined nozzle. The multi-head dual fuel combined nozzle is characterized by comprising a head nozzle 1, a center nozzle group 2, a nozzle mounting side 3, a center liquid fuel nozzle mounting side 4 and a nozzle casing body 5; the nozzle casing body 5 comprises a head nozzle casing body 6 and a center nozzle casing body 7; the center nozzle group 2comprises a gas fuel nozzle, a pilot nozzle 9 and a center liquid fuel nozzle10; the multi-head dual fuel combined nozzle has the advantages that the traditional mechanical structure is improved, thecombustion efficiency of the combustion chamber is enhanced, and the annihilation performance of the combustion chamber is improved. The multi-head dual fuel combined nozzle can be applied to the combustion turbine combustion chambers which are operated by adopting liquid fuel and gas fuel.

Description

technical field [0001] The invention relates to the mechanical field, and in particular provides a multi-head dual-fuel combined nozzle. Background technique [0002] When the gas turbine combustor uses gas fuel, such as natural gas, coke oven gas, etc., it generally needs to use liquid fuel, such as diesel, as a backup fuel to ensure that the gas turbine can still work normally when the gas fuel is lacking or suddenly interrupted, and the utilization rate of the gas turbine can be improved. Therefore, the nozzles installed on the gas turbine combustors are generally dual-fuel nozzles that can use both gaseous fuel and liquid fuel. At present, the installation of the nozzle and the flame tube of the gas turbine combustor mainly has the following two structural forms. The first structural form is that one flame tube corresponds to one dual-fuel nozzle, and the second structural form is that one flame tube corresponds to multiple dual-fuel nozzles. The nozzles are connected t...
