Description

Technical Field

[0001] The utility model belongs to the technical field of chimneys, and more specifically, relates to a chimney device for a combustion furnace. Background Art

[0002] A combustion furnace is a device that releases heat energy through a chemical reaction between fuel and oxygen. Furnaces are widely used in various industries, including energy, chemicals, metallurgy, and building materials. Depending on the fuel type and combustion method, furnaces can be categorized as gas, coal, oil, biomass, and fuel cell. The main components of a furnace include the combustion chamber, burner, air supply system, and exhaust system.

[0003] Coal-fired furnaces generate a large amount of dust during the combustion process, which is discharged into the flue along with the flue gas. If this dust is not treated, it will adhere to the inner wall of the flue, gradually forming a thick layer of dust. This will not only reduce the ventilation efficiency of the flue, but may also cause environmental pollution.

[0004] The existing combustion furnace chimney filters dust through a filter, but the filter needs to be frequently replaced to maintain the working effect of the filter. However, the combustion furnace chimney is large, which makes the filter also large, making replacement very inconvenient.

[0005] In summary, the present invention provides a chimney device for a combustion furnace to solve the above problems. Utility Model Content
