Abstract

The invention relates to a coal-firewood combustion furnace with double flue pipes. The coal-firewood combustion furnace is characterized in that the bottom of the hearth (4) is connected at the center of a hollow bottom plate (8), a furnace bridge (7) for providing air for the furnace is arranged at the joint of the inner furnace core (5) and the bottom plate (8), the furnace bridge (7) is mounted at the bottom plate (8) which is provided with a hollow hole for providing air for combustion of the furnace, and an ash hopper (15) for storing ash is arranged below the furnace bridge (7). The interlayer space between the inner furnace core (5) and an outer furnace barrel (6) is communicated with the interlayer space of the bottom plate (8) at the lower part, and the interlayer space between the inner furnace core (5) and the outer furnace barrel (6) is communicated with an interlayer space of a tempering box (3) at the upper part. The top of the side face of the tempering box (3) is connected on a transverse smoke pipe (10), and the transverse smoke pipe (10) is connected on a chimney (11) for exhausting waste gas outwards. The coal-firewood combustion furnace with the double flue pipes has the advantages of being simple in structure, convenient to operate and high in heat efficiency.

Description

technical field [0001] The invention relates to a coal wood burning stove with double flue pipes. Background technique [0002] At present, there are many styles of coal-fired stoves on the market, most of which use chimneys to discharge upwards from the side of the coal-fired stove. The coal-fired stove has incomplete combustion, which is not conducive to heating. Now we have innovatively designed a coal wood burning stove with double flue pipes. The hot gas of the coal wood burning stove can enter the bottom and then be discharged out of the room through the smoke pipe. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a coal wood burning stove with double flue pipes. [0004] The technical scheme of the present invention is: a coal wood burning furnace with double flue pipes, which is characterized in that a pot body is provided on the furnace panel for easy removal, and a tempering box is provided under the po...
