Abstract

The invention relates to a bauxite shaft kiln combustion device which comprises a fuel channel, a hot air channel and a combustion plate. One end of the fuel channel is sealed through a cover plate, a maintenance hole is formed in the cover plate, the other end of the fuel channel is communicated with the hot air channel through a flange, a fuel inlet is formed in the fuel channel, the hot air channel is a double-layer casing pipe, the double-layer casing pipe comprises an inner pipe and an outer pipe, the annular space between the inlet end of the inner pipe and the inlet end of the outer pipe is sealed through a steel board, the inner pipe and the outlet end of the outer pipe are fixed together through the combustion plate, a hot air inlet is formed in the outer pipe, and a plurality of baffle boards which are obliquely arranged along the outer surface of the inner layer of the casing pipe are arranged on the outer surface of the inlet end of the inner pipe. The bauxite shaft kiln combustion device can improve combustion efficiency, energy is saved by more than 30%, consumption is reduced by more than 30%, carbon emissions are reduced, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to a combustion device, in particular to a bauxite shaft kiln combustion device. Background technique [0002] Industrial heating furnace occupies an important position in industry and is widely used in the field of industrial heating. Regarding the combustion efficiency and safety control of industrial heating furnaces, it has always been a hot spot for continuous exploration and progress in the industrial field. Because the fuel resources needed for combustion are non-renewable resources, such as coal, oil, gas, etc., the level of combustion efficiency directly affects the utilization rate of resources, and is also directly related to the control of production costs of enterprises, and the safety of production is the key to the production of enterprises. The country and enterprises are widely concerned. Therefore, the combustion efficiency and safety control of industrial furnaces have always been the subject that the industry ...
