Problems solved by technology

[0002] The flue design of the existing air return furnace is not reasonable, either it is not easy to ignite, or the heat is not evenly distributed on the furnace body when the fuel is burning, and the part of the furnace body near the flue burns very hot while the other side is very hot. It is very low, the table is very hot and the temperature of the base is not enough, which affects heating; in addition, the use of fuel is very limited, and the combustion of coal is not sufficient. It only burns in the middle of the furnace, and the circle near the furnace is not completely burned; The gap between the furnace bridges is not smooth, and the high-temperature ashes after combustion are accumulated on the furnace bridges, which makes the furnace easily deformed due to high temperature, and also hinders the air intake channel of the furnace

Abstract

The invention discloses a durable return air warming furnace, relates to a civilian use furnace and designs an optimal flue. A semi ring-shaped smoke deflector is arranged between a hearth and a furnace body, high temperature air-returning smoke can enter a return air flue after bypassing the semi ring-shaped smoke deflector, thus the furnace can be heated fully. The boiler furnace is extended; a flame bridge is arranged on the middle lower part of the boiler furnace; the latus rectum of the flame bridge is larger; high temperature ash generated by combustion falls on a rotating ash door so as to avoid the deformation of the hearth caused by the accumulation of the high temperature ash, heat a base and be convenient to warm. The furnace is also provided with an inner chamber made of a fireproof material, so the peripheral temperature of burning coal is maintained and the coal can be fully combusted. The durable return air warming furnace provided by the invention has high latitude to fuel, can make full use of fuel heat, can heat water quickly, make various fuels fully combusted, simplify the method of application, and has convenient use. The integral furnace is integrally formed by a casting mode, and is firm and durable.

Description

technical field [0001] The invention relates to a civil stove, in particular to a durable return air heating stove. Background technique [0002] The flue design of the existing air return furnace is not reasonable, either it is not easy to ignite, or the heat is not evenly distributed on the furnace body when the fuel is burning, and the part of the furnace body near the flue burns very hot while the other side is very hot. It is very low, the table is very hot and the temperature of the base is not enough, which affects heating; in addition, the use of fuel is very limited, and the combustion of coal is not sufficient. It only burns in the middle of the furnace, and the circle near the furnace is not completely burned; The gap between the furnace bridges is not smooth, and the high-temperature ashes after combustion are accumulated on the furnace bridges, which makes the furnace easily deformed due to high temperature, and also hinders the air intake channel of the furnace...
