Low-cost trapped vortex combustor

Abstract

The invention discloses a low-cost trapped vortex combustor, and belongs to the technical field of combustor structures. The low-cost trapped vortex combustor comprises an air inlet cavity, an air inlet valve, a combustion chamber front section, a glow plug, a fuel vapor inlet cavity, an exhaust flange, a fuel vapor inlet valve and a combustion chamber rear section; the combustion chamber front section is installed in the air inlet cavity in a sleeved mode; a spiral cavity is formed between the inner circumferential surface of the air inlet cavity and a spiral groove in the combustion chamberfront section, the large diameter end of the combustion chamber rear section is coaxially and fixedly connected with the open end of the combustion chamber front section in a butting mode, and the fuel vapor inlet cavity is formed in the outer part of the small diameter end of the combustion chamber rear section in a sleeved mode; the air inlet valve is installed in an air inlet of the air inlet cavity; the fuel vapor inlet valve is installed in a fuel vapor inlet port of the fuel vapor inlet cavity; the exhaust flange is installed on the end surface of the small diameter end of the combustionchamber rear section; and the glow plug is fixed to the combustion chamber rear section. The low-cost trapped vortex combustor has the characteristics of sufficient combustion, simple structure, compactness, wide stable working range, less pollution divergence and low cost.

Description

technical field [0001] The invention belongs to the technical field of combustion chamber structure, and in particular relates to a low-cost trapped vortex combustion chamber. Background technique [0002] The combustion chamber is a device in which fuel or propellant is burned to generate high-temperature fuel vapor. It is a kind of combustion equipment made of high-temperature resistant materials. With the increasingly serious energy crisis, countries around the world have begun to pay attention to the promotion of clean energy. At the same time, improving the efficiency of fossil fuel combustion can improve energy utilization efficiency and reduce harmful gas emissions. The combustion chamber is a place where fuel is burned. Domestic fuel-fired steam stoves and direct-flow combustors commonly used in the ground industry usually cannot ensure sufficient combustion of fuel, producing a large amount of harmful gas and causing a great waste of energy. Therefore, one of the im...

With the increasingly serious energy crisis, countries around the world have begun to pay attention to the promotion of clean energy. At the same time, improving the efficiency of fossil fuel combustion can improve energy utilization efficiency and reduce harmful gas emissions. The combustion chamber is a place where fuel is burned. Domestic fuel-fired steam stoves and direct-flow combustors commonly used in the ground industry usually cannot ensure sufficient combustion of fuel, producing a large amount of harmful gas and causing a great waste of energy. Therefore, one of the important ways to improve energy utilization is to increase fuel consumption. Sufficiency of combustion
