Dual-fuel air vortex combustor

Abstract

The invention provides a dual-fuel air vortex combustor. The dual-fuel air vortex combustor comprises an air inlet cavity, a spinning disk device, a combustion chamber, a fuel gas spray gun and an oilgun, wherein the spinning disk device is arranged in the air inlet cavity and used for generating air vortex; the spinning disk device comprises a plurality of spinning disks arranged in an annular array mode; the combustion chamber and the spinning disk device are coaxially arranged in parallel, and the combustion chamber communicates with an air outlet port of the spinning disk device; the fuelgas spray gun is arranged in an inner cavity of the spinning disk device in a penetration mode; a spray nozzle of the fuel gas spray gun is located at an inner port of the combustion chamber; and theoil gun is arranged in the inner cavity of the fuel gas spray gun in a penetration mode, and the head of the oil gun is arranged at the inner port of the combustion chamber. Compared with the prior art, the dual-fuel air vortex combustor has the advantages that combustion air goes into the spinning disk device to spin inwards and goes into the combustion chamber along the fuel gas spray gun; thecombustion air rotates under the action of high-speed vortex, has high kinetic energy and can be quickly mixed with fuel gas and fuel oil to be sufficiently combusted so as to provide relatively stable and short flame, and the power of the combustor is greatly increased.

Description

technical field [0001] The invention relates to the technical field of combustion, in particular to a dual-fuel air vortex burner for gas and fuel oil. Background technique [0002] Most of the existing air burners are of simple nozzle design, do not have a wide adjustment ratio, and the input power is not large. Simultaneously, under the situation of excess gas or excess air, the stability of combustion is not good. The biggest problem is that the length of the flame is extended with the flow of gas and fuel oil, which depends on the length of the combustion chamber and has high requirements on the pressure of the combustion air. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a dual-fuel air swirl burner. [0004] In order to achieve the above object, the technical solution adopted by the present invention to solve the technical problems is: a dual-fuel air swir...
