A fuel nozzle of a low-pollution combustion chamber belongs to the technical field of heavy duty gas turbines. The invention provides a fuel nozzle of a combustion chamber capable of realizing low pollution combustion, comprising an outer casing, wherein, a gas way nozzle is fixed in the outer casing by a first convex plate arranged in a gas way pipeline; the gas way nozzle is internally providedwith a water way nozzle with a third convex plate corresponding to the first convex plate in the gas way pipeline; the water way nozzle is fixed in the gas way nozzle by the third convex plate and the first convex plate in the gas way pipeline; the water way nozzle is internally provided with an oil way nozzle with a fourth convex plate corresponding to a second convex plate in a water way pipeline; the oil way nozzle is fixed in the water way nozzle by the fourth convex plate and the second convex plate in the water way pipeline; the oil way nozzle is internally provided with a swirler with tangential holes; the rear end of the oil way nozzle is connected with an oil way pipeline by a connecting piece.
Description
Technical field: [0001] The invention belongs to the technical field of heavy-duty gas turbines, in particular to a fuel nozzle for a low-pollution combustion chamber, which is applied to the combustion chamber of a heavy-duty gas turbine. Background technique: [0002] With the development of society and economy, people gradually foresee the long-term threats to human beings due to the limited earth resources and energy sources and the aggravated destruction of the ecological environment. Electricity is a symbol of modern civilization, but the consumption of power generation energy and the pollution of the environment have become a problem of sustainable development. Obviously, improving energy efficiency is the first choice to control greenhouse gas emissions, and gas turbines pay great attention to low NO X emissions from combustion technology. Inject a certain proportion of water or steam into the combustion zone to reduce the temperature of the combustion flame, which...
