Embodiment 1
[0029] figure 1 It is a schematic diagram of the internal structure of the connection between the burner and the furnace provided by Embodiment 1 of the present invention.
[0030] Please refer to figure 1 , the burner includes: a burner outlet 7, a primary air channel 1, a secondary air channel 2, and an oil and gas supply gun 3.
[0031] The burner outlet 7, which contains one or more fuel outlets, is used to connect to the furnace 9 of the boiler, so as to deliver one or more fuels into the furnace 9 for combustion. Specifically, the burner outlet 7 is composed of one or more fuel outlets to form a unified outlet for flexible connection with the furnace 9, where the furnace 9 refers to the furnace of a large power plant pulverized coal boiler.
[0032] The side wall of the primary air channel 1 is provided with a primary air inlet, and the other end extends to the burner outlet 7 and is formed as a primary air outlet. Primary air channel 1 is used to convey the mixture o...
Embodiment 2
[0057] figure 2 It is a schematic diagram of the internal structure of the burner provided by Embodiment 2 of the present invention.
[0058] Please refer to figure 2 , on the basis of the first embodiment, the burner of this embodiment adds a biomass powder supply gun 4, one end of which is formed as a powder inlet, and the other end extends to the burner outlet 7 and is formed as a powder outlet for conveying biomass powdered fuel. The biomass powder in the biomass powder supply gun 4 enters the furnace 9 for combustion under the air of the primary wind speed in the primary air channel 1, so that traditional large-scale thermal power plants can burn a large amount of renewable energy such as biomass powder fuel.
[0059] Optionally, the biomass powder supply gun 4 is arranged at the center of the primary air channel 1 , that is, the axis of the biomass powder supply gun 4 coincides with the axis of the primary air channel 1 .
[0060] Optionally, the cross section of th...
Embodiment 3
[0067] The difference between the burner of this embodiment and the second embodiment is that the installation position of the biomass powder supply gun 4 is different. In this embodiment, the axis of the biomass powder supply gun 4 and the axis of the primary air channel 1 form a second angle.
[0068] Optionally, the angle range of the second included angle is 0°-30°.
[0069] The structure and connection relationship of other components of the burner in this embodiment are the same as those in Embodiment 2, and will not be repeated here.
