Oil and gas compound burner

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 and gas source with unstable pressure as a combustion raw material, and can ensure the flame balance when the oil and gas are burned. Background technique [0002] my country is rich in coal resources but lack of oil and gas resources. Therefore, most users use coal as a combustion energy. However, although my country is rich in coal resources, the coal quality is variable and the distribution is extremely uneven. This is for the users. It is impossible to provide a stable coal source, so many thermal power plants use coal as the main combustion raw material, but also prepare combustion equipment that uses oil and gas. In addition, when coal is burned, it can only provide 80% of its own combustion value. The smoke after combustion contains more harmful substances. Direct emission into the atmosphere will greatly affect air quality. Starting from the...
