DETAILED DESCRIPTION

[0023] The technical scheme in the embodiment of the utility model will be clearly and completely described below.

[0024] As Figures 1-4 shown, a full premixing gasification combustion device comprises a furnace head body 1 and a combustible gas pipe 2, the furnace head body 1 has a gasification chamber 3 and a combustion chamber 4, and the combustion chamber 4 is provided with a fire divider 5.

[0025] One end of the combustible gas pipe 2 is communicated with the gasification chamber 3, and the other end of the combustible gas pipe 2 is located in or below the combustion chamber 4; that is, the combustible gas generated in the gasification chamber 3 enters the combustible gas pipe 2 through one end of the combustible gas pipe 2 and is discharged through the other end of the combustible gas pipe 2.

[0026] The igniter 6 is arranged in the combustion chamber 4, and the combustible gas discharged through the other end of the combustible gas pipe 2 can be ignited in the combustion chamber 4 through the igniter 6, and the flame after ignition is divided by the flame divider 5. The combustible gas pipe 2 is a U-shaped pipe, which can avoid the phenomenon of oil return.

[0027] The heating device 7 is fixedly connected to the furnace head body 1 and is used for heating in the initial stage (unburning). The gasification chamber 3 is communicated with the air inlet pipe 8 and the oil inlet pipe 9, and specifically, the air inlet pipe 8 is communicated with the combustion air fan, and the oil inlet pipe 9 is communicated with the oil pump, which is used for pumping the oil in the oil tank into the oil inlet pipe 9.

[0028] The working principle of the device is as follows: first, heating is performed through the heating device 7; then, the oil pump, the combustion air fan and the igniter 6 are started at the same time. The oil pump delivers the fuel oil in the oil tank into the gasification chamber 3, the premixing combustion air fan blows the oil and air into the gasification chamber 3, and the oil and air are mixed to form combustible gas. The combustible gas is ignited by the igniter 6; the heat generated after combustion heats the gasification chamber 3, that is, in the subsequent combustion process, the heating device 7 can be closed.

[0029] Further, the oil inlet pipe 9 is located in the air inlet pipe 8, which can better blow the oil into the gasification chamber 3 and improve the gasification and mixing effect.

[0030] Further, the heating device 7 is an electric heating device 7, which can adopt an electric heating belt or any other heating device 7 with a heating function.

[0031] Further, the other end of the combustible gas pipe 2 is fixedly provided with an air outlet mesh cover 10, which can avoid the combustible gas from gushing out and causing the defects of difficult ignition and smoke during ignition. In addition, the air outlet mesh cover 10 can block the combustible gas and reduce the problems of odor during shutdown and internal combustion.

[0032] Further, the shape of the oil inlet pipe 9 is a "7" shape, which can also be an "l" shape, and the specific shape can be set according to the actual situation.

[0033] Further, the shape of the furnace head body 1 is preferably a circular ring.

[0034] Further, the igniter protection needle 11 is arranged in the combustion chamber 4.

[0035] The above only describes the preferred embodiments of the present application in detail, but the present application is not limited to the above embodiments.
