Description

Technical Field

[0001] The utility model relates to the technical field of heating stoves, in particular to a smokeless firewood heating stove. Background Art

[0002] Smokeless wood-fired heating stoves are economical and affordable. For urban-rural fringe areas and vast rural areas without central heating and without gas heating conditions, wood-fired heating stoves with low heating costs are an ideal choice.

[0003] The chimneys of existing smokeless wood-fired heating stoves are all made of stainless steel. After long-term use, the chimney pipes contain carbon particles, ash and other pollutants in the flue gas produced by combustion. These substances are deposited inside the chimney, which will cause blackening and carbon accumulation inside over time. In order to avoid blockage inside the chimney pipe, the chimney pipe needs to be disassembled and cleaned regularly. However, the disassembly process of the existing chimney pipe is relatively cumbersome and inconvenient for quick disassembly. Therefore, a smokeless wood-fired heating stove is proposed to solve the above-mentioned problems. Utility Model Content
