Problems solved by technology
[0002] Generally, the flue gas produced by boiler combustion contains a certain amount of ash, especially for boilers burning coal, domestic waste, RDF, RPF and biomass fuels, etc., more ash is brought to the rear heating surface. When the boiler needs to set up a bypass In the case of pipelines, the structural layout wastes space, and often encounters the problems of dust accumulation, dust blocking and narrow adjustment range of the flow section, which eventually leads to a reduction in the heat absorption capacity of the heating surface

Embodiment Construction
[0010] See figure 1 , figure 2 , which includes an upper ash hopper 1, an ash falling pipe 2, and a lower smoke chamber 3. The ash falling pipe 2 is connected to the bottom of the upper ash hopper 1 and the lower smoke chamber 3. The upper ash hopper 1 is connected to the lower smoke chamber 3 through the ash falling pipe 2. The side part of the ash hopper 1 and the lower smoke chamber 3 are communicated through a bypass duct 4, and the upper entrance of the bypass duct 4 is provided with a plug-in door 5, and the lower end of the plug-in door 5 when closed is in close contact with the inner wall 6 of the ash hopper wall, The running track of the plug-in door 5 is inclined to the horizontal plane and is installed inside the bypass duct 4;
[0011] The two sides of the upper ash hopper 1 are symmetrically arranged with bypass pipes 4; the inclination angle between the running track of the plug-in door 5 and the horizontal plane is 50°~90°; the top 7 of the bypass pipe 4 horiz...

The invention relates to a boiler by-pass flue which has compact and rational structure, saves space and has wide adjustment range, so as to lead ash to be discharged smoothly and ensure heat adsorption ability of a heating surface; the boiler by-pass flue comprises an upper ash bucket, an ash pipe and a lower ash chamber; the ash pipe is communicated with the bottom part of the upper ash bucket and the lower ash chamber, and the upper ash bucket is communicated with the lower ash chamber by the ash pipe; the boiler by-pass flue is characterized in that: the side part of the upper ash bucket and the lower ash chamber are communicated by a by-pass pipeline, and an inserted slab door is arranged at the inlet position at the upper part of the by-pass pipeline, when the inserted slab door is closed, the lower end of the inserted slab door is closely attached to the inner wall of the ash bucket wall, and an operation rail of the inserted slab door is inclined to the water plane and is arranged in the by-pass pipeline.
Description
technical field [0001] The invention relates to the field of boiler flue structures, in particular to a boiler bypass flue. Background technique [0002] Generally, the flue gas produced by the combustion of boilers contains a certain amount of ash, especially the boilers burning coal, household waste, RDF, RPF and biomass fuel, etc., bring more ash to the rear heating surface. When the boiler needs to be set with a bypass When pipelines are used, the structural arrangement wastes space, and often encounters the problems of fouling, fouling, and narrow adjustment range of the flow cross section, which eventually leads to the reduction of the heat absorption capacity of the heating surface. SUMMARY OF THE INVENTION [0003] In view of the above problems, the present invention provides a boiler bypass flue, which has a compact and reasonable structure, saves space, and has a wide adjustment range, thereby enabling the smooth discharge of ash and ensuring the heat absorption ...
