Double-cylinder-shaped combustion furnace

Abstract

The invention relates to a double-cylinder-shaped combustion furnace. The double-cylinder-shaped combustion furnace is characterized in that a flue cylinder body (5) which supports a table top (2) andencircles the smoke to enable the smoke to descend is arranged at the bottom of the table top (2), and the bottom of the flue cylinder body (5) is connected to a smoke interlayer (11). A furnace core(4) and an air inlet cylinder body (14) are arranged in the center of the interior of the flue cylinder body (5). The furnace core (4) is arranged in the center of the air inlet cylinder body (14). Afurnace bridge (9) is arranged at the bottom of the furnace core (4), and an ash and residue hopper (10) which stores ash and residues and can be drawn outwards is arranged below the furnace bridge (9). A furnace door (13) which communicates with the interior of the furnace core (4) and can be opened outwards is arranged on the lower portion of the flue cylinder body (5). A smoke pipe (7) which communicates with a chimney (8) is arranged on the smoke interlayer (11). The double-cylinder-shaped combustion furnace is novel in design and reasonable in structure, the heat of the gas can be fullytransmitted to the smoke interlayer, the heat exchange rate is substantially improved, and the quality of life is improved.

Description

technical field [0001] The invention relates to a double cylinder burner. Background technique [0002] At present, there are still many households using burning stoves among the majority of urban and rural residents. The firewood burning stoves widely used in rural areas have low thermal efficiency and their design is not reasonable. Oxygen supply to fuel combustion is also not sufficient. Ordinary firewood burning stoves are built with bricks and mud and other materials. In addition to being large in size and unable to be moved, most of them also have insufficient combustion, weak firepower, high consumption of firewood, low heat utilization rate, serious smoke production, and environmental pollution. Large and other disadvantages, especially the serious pollution of smoke and dust.

Problems solved by technology

Ordinary firewood burning stoves are built with bricks and mud and other materials. In addition to being large in size and unable to be moved, most of them also have insufficient combustion, weak firepower, high consumption of firewood, low heat utilization rate, serious smoke production, and environmental pollution. Large and other disadvantages, especially the serious pollution of smoke and dust. The traditional way of ventilation and intake of firewood burning stoves is passive and purely from the bottom of the stove. Insufficient ventilation and intake will easily affect the efficiency of firewood combustion. The way of adding is generally from the upper or lower part, which is troublesome. At the same time, the temperature of the flue gas in the chimney is high, and it is directly discharged, which is easy to burn people, and there is a problem of low heat utilization of direct gas discharge.
