Embodiment Construction

[0022] Such as figure 1 , 2 As shown, the oil-gas composite burner of the present invention includes an oil pipe 1 for supplying oil, an air pipe 2 for providing gas provided outside the oil pipe 1, and a casing 3 for providing combustion-supporting air for the oil pipe 1 is arranged between the air pipe 2 and the oil pipe 1 The oil pipe 1 is movably installed in the sleeve 3 through the oil pipe support rib 101 fixedly arranged on the outer surface, and the sleeve 3 is in sliding contact with the inner surface of the air pipe 2 through the inclined rotary piece 302 fixed on the outer surface, and the air pipe enters The gas end is provided with a gas box 4 communicating with the gas, and outside the gas pipe 2 is provided a wind box 5 including the gas pipe to provide combustion-supporting air. On the wind box 5, there is an air inlet 501 for air to enter and a gas outlet with the gas pipe. The flame nozzle 502 corresponding to the end is provided with an ignition device 9 a...

Abstract

The invention discloses an oil and gas compound burner which comprises an oil pipe and a gas pipe, wherein a casing pipe used for supplying combustion air for the oil pipe is arranged between the gas pipe and the oil pipe, the oil pipe is movably arranged in the casing pipe through oil pipe supporting rods which are fixedly arranged on the outer surface, the casing pipe is glidingly contacted with the inner surface of the gas pipe through oblique spiral slices which are fixedly arranged on the outer surface of the casing pipe, a gas box communicated with gas is arranged on the gas inlet end of the gas pipe, an air box containing the gas pipe supplying the combustion air is arranged outside the gas pipe, an air inlet through which air can enter and a flame spout corresponding to the gas outlet end of the gas pipe are formed in the air box, and an ignition device and a flame monitor used for detecting a burning state are arranged on the gas outlet end of the gas pipe. The oil and gas compound burner disclosed by the invention adopts the structure of double pipes in a sleeving manner and gas pipe in the circumferential direction, under realizing the foundational function of ignition, the oil and gas co-burning and the pure gas burning also can be realized, simultaneously, and he stable and high-efficiency burning in gas supplying in a wide-margin fluctuation manner can be realized, and energy sources can be saved maximally.

Description

technical field [0001] The invention relates to the field of energy, in particular to an oil-gas composite burner that can use an oil-gas source with unstable pressure as a combustion raw material, and can ensure the balance of the flame when the oil-gas burns. Background technique [0002] my country is rich in coal resources but scarce in oil and gas resources, so most users use coal as combustion energy. However, although my country has abundant coal resources, the quality of coal is variable and the distribution is extremely uneven. Just can not provide stable coal source, so many thermal power plants are also prepared to use oil and gas combustion equipment while using coal as the main combustion raw material. In addition, coal can only provide 80% of its own combustion value when it is burned. , in order to improve the environmental quality, the state enforces the new environmental protection standard, which requires reducing the concentration of nitrogen oxide emissio...
