Description
Technical Field
The utility model belongs to the technical field of the environmental protection burning, especially, relate to a boiler burner.
Background
The boiler burner has a complex structure and high manufacturing cost. And after the installation, the inner structure is fixed, and the pipeline is difficult to adjust according to the force supply condition of the boiler. At present, the fuel of the boiler mainly comprises diesel oil, coal, petroleum, natural gas, blast furnace gas, coke oven gas and the like. Natural gas is a relatively clean energy, but the price is more expensive, and light diesel oil is relatively low in price, and there are some dual-purpose combustors of oil gas in the market at present, but the structure of combustor is fixed, when using diesel oil, because the spray gun export of natural gas exposes at the high temperature of boiler, causes the damage very easily.
SUMMERY OF THE UTILITY MODEL
Based on above defect, the utility model discloses a structure adjustable combustor, natural gas spray gun can freely advance and move back in gas passageway, can give the power condition according to the boiler, adjusts natural gas spray gun's use number, does not use the natural gas as the burning medium simultaneously, and when adopting light diesel oil as the burning medium, move back the gas spray gun inside the combustor, can effectively protect gas spray gun, extension practical life.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a boiler burner comprises a fuel oil channel, wherein a first combustion-supporting air channel is arranged around the outer circumference of the fuel oil channel, a fuel gas channel is arranged around the outer circumference of the first combustion-supporting air channel, and a second combustion-supporting air channel is arranged around the outer circumference of the fuel gas channel;
the fuel oil channel is a metal hollow round pipe positioned in the center of the boiler burner, the inlet is connected with a fuel oil source, and the outlet is positioned in the boiler; the cross sections of the first combustion-supporting air channel and the second combustion-supporting air channel are circular rings taking the central fuel channel as the circle center, the inlet of the combustion-supporting air channel is connected with a combustion-supporting air source, and the outlet is positioned in the boiler; the inlet of the gas channel is connected with a gas source, and the outlet of the gas channel is positioned in the boiler;
the gas channel is a series of parallel gas spray guns arranged around the circumferential direction of the first combustion-supporting air channel, the inlets of the gas spray guns are connected with a gas source through hoses, and each gas spray gun can freely advance and retreat in the gas channel.
Preferably, a plurality of gas spray guns are arranged in the gas channel.
Furthermore, a support groove is arranged in the gas channel and used for supporting each gas spray gun to advance and retreat in the gas channel.
Furthermore, the hose connecting the inlet of the gas spray gun and the gas source is a metal or plastic hose.
Further, the gas spray gun is also correspondingly provided with a cylinder.
Furthermore, the outlet end faces of the first and second combustion-supporting air channels are provided with mixed wind wheels for providing combustion-supporting air for fuel.
Preferably, the medium in the fuel oil channel is light diesel oil, and the medium in the fuel gas spray gun is natural gas.
The utility model has the advantages as follows:
the utility model discloses a dual-purpose combustor of oil gas, the spray gun of natural gas is connected with natural gas source with the hose, and the spray gun can freely advance and retreat in the inside gas passageway of combustor. On one hand, when natural gas is used as a combustion medium, the number of the used natural gas spray guns can be adjusted according to the force supply condition of the boiler, and the spray guns which are not used are pushed into the combustor; on the other hand, when light diesel oil is used as a combustion medium, all the gas spray guns are withdrawn into the gas channel in the combustor, so that the outlets of the spray guns can be effectively protected, and the spray guns are prevented from being exposed in the high-temperature environment of the boiler.
