Description

Technical Field

[0001] The utility model relates to the technical field of biomass boilers, in particular to a combustion chamber structure of a biomass boiler. Background Art

[0002] Biomass boiler is a type of boiler. Its notable feature is that it uses biomass energy as fuel. This boiler can effectively convert biomass into thermal energy to meet various industrial and living needs. There are many types of biomass boilers, including biomass steam boilers, biomass hot water boilers, biomass hot air furnaces, etc., which are suitable for different application scenarios;

[0003] When the combustion chamber of a biomass boiler burns biomass fuel, the properties of the biomass fuel itself will affect the heat conduction efficiency. Different types of biomass fuel have different combustion characteristics and calorific values, which directly affect the heat generation and conduction in the combustion chamber. In addition, factors such as the air ratio and fuel input during the combustion process need to be precisely controlled, otherwise it will affect the combustion effect and thus the heat conduction. Since the heat cannot be fully conducted to the furnace and directly discharged with the flue gas, part of the heat energy may be lost in the combustion chamber, resulting in the failure to completely convert the biomass fuel into heat energy.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-Figure 5 As shown, the utility model provides a biomass boiler combustion chamber structure, including two partitions 1, a plurality of heat-conducting tubes 2 are fixedly connected between the two partitions 1, a combustion chamber 3 is arranged between the two partitions 1 located below the heat-conducting tubes 2, the combustion chamber 3 includes three smooth furnace shells 4, and two adjacent smooth furnace shells 4 are fixedly connected by a corrugated furnace shell 5, wherein one side of the two smooth furnace shells 4 are respectively inserted and installed in the corresponding partitions 1, a spiral guide plate 6 is arranged in the corrugated furnace shell 5, and the spiral guide plate 6 is fixedly installed in the corrugated furnace shell 5 through a mounting rod 7, and a heat-conducting sleeve 8 is also movably installed on the outside of the plurality of heat-conducting tubes 2.

[0022] like Figure 3-Figure 4 As shown, a plurality of air holes 9 are provided in the spiral guide plate 6. The plurality of air holes 9 are provided in the spiral guide plate 6 to ensure that the biomass fuel and the flame are guided and the air passage of the entire combustion chamber 3 is unobstructed. A plurality of fixing rods 10 are fixedly installed on the top of the spiral guide plate 6, and a fixing seat 11 is fixedly installed on the bottom of the fixing rod 10. A slot 12 is provided in the fixing seat 11, and a card slot 13 is provided in the slot 12. The mounting rod 7 is in a U-shaped structure, and a plurality of plug rods 14 are fixedly installed on the mounting rod 7. A fixing ring 15 is fixedly installed on the outer side of the plug rod 14. Connecting plates 16 are also fixedly installed at both ends of the mounting rod 7. The plug rods 14 are inserted and installed in the corresponding slots 12 through the fixing rings 15. The tops of the two connecting plates 16 are fixedly installed in the corresponding smooth furnace 4 by welding. By setting the mounting rods 7, the plug rods 14 and the fixing rods 10, the fixed installation of the spiral guide plate 6 can be realized, and the disassembly and assembly and maintenance of the spiral guide plate 6 in the later stage are convenient.

[0023] like Figure 3 As shown, a plurality of heat-conducting sleeves 8 are fixedly connected to each other through a first heat-conducting plate 17, and a plurality of heat-conducting sleeves 8 are also fixedly connected to the outer surface of one of the smooth furnace 4 through a second heat-conducting plate 18.

[0024] It should be noted that the utility model is a combustion chamber structure of a biomass boiler.

Therefore, the biomass fuel will burn on the inner wall of the smooth furnace 4 and the corrugated furnace 5, so that the smooth furnace 4 and the corrugated furnace 5 will heat up more quickly, so that higher heat can be transferred to the heat medium water in the boiler. At the same time, through the arrangement of multiple heat-conducting sleeves 8 and the first heat-conducting plate 17 and the second heat-conducting plate 18, part of the heat can be directly transferred to the heat-conducting pipe 2, so that the heat conduction efficiency can be further improved, and the heating efficiency of the unit fuel can be improved;

[0025] When the spiral guide plate 6 is disassembled for maintenance at a later stage, it is only necessary to desolder the two spiral guide plates 6 from the smooth furnace 4 at both ends, so that the spiral guide plate 6 can be taken out from the corrugated furnace 5 through the mounting rod 7, and the fixing seat 11 can be separated from the corresponding insertion rod 14, so that the spiral guide plate 6 and the mounting rod 7 can be disassembled, and then, different parts can be maintained according to actual maintenance needs.
