Abstract

The purpose of the present invention is to provide a dual-fuel gas turbine bleed air purging method, which includes dual-fuel nozzles, fuel purge pipelines and gas purge pipelines. The fuel purge pipelines are sequentially installed with throttling components, first-stage fuel purge Sweeping cut-off valve, the outlet of the first-stage fuel purge cut-off valve is connected to the first branch pipeline of fuel and the second branch pipeline of fuel, and the first branch pipeline of fuel is installed in sequence with the second-stage fuel purge shut-off valve, the second One check valve, the dual-fuel nozzle is connected behind the first check valve, the first-stage gas purge cut-off valve is installed on the gas purge pipeline, and the outlet of the first-stage gas purge cut-off valve is connected to the first branch pipeline of gas And the second branch pipeline of gas, the second-stage gas purge circuit cut-off valve and the second check valve are installed in sequence on the first branch pipeline of gas, and the dual-fuel nozzle is connected behind the second check valve. The invention can switch online, meet the requirements of different purge gas sources, and can run continuously and stably.

Description

technical field [0001] The invention relates to a gas turbine purging method, in particular to a dual-fuel gas turbine purging method. Background technique [0002] In the process of extracting crude oil, a large amount of oil-associated gas is often produced. This type of associated gas is flammable, explosive, and difficult to store and transport. For safety reasons, it will be directly burned from the beginning of extraction. , resulting in a serious waste of energy. Dual-fuel gas turbine is a kind of power equipment that can effectively solve this problem. It can not only provide power for crude oil development, but also use oil-associated gas as gaseous fuel to work, and realize the original liquid fuel and oil-associated gas without stopping the machine. The undisturbed online switching between them improves the adaptability of the gas turbine to the fuel, effectively utilizes the oil associated gas, and solves the various fuel requirements in different states during ...
