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.
