Novel air return furnace structure

Abstract

The invention discloses a novel air return furnace structure. The structure comprises a furnace body and an annular cavity structure arranged in a pedal base body located at the bottom of the furnace body. A smoke discharge passage is arranged between an air exhaust port of the furnace body and a chimney. The interior of the smoke discharge passage is provided with a baffle plate such that a first flow gas channel and a second flow gas channel are formed in the smoke discharge passage. A switch baffle plate is arranged between the first flow gas channel and the second flow gas channel. A first through hole is arranged between the first flow gas channel and the pedal base body. A second through hole is arranged between the second flow gas channel and the pedal base body. A first baffle plate is arranged in the annular cavity structure between the first through hole and the second through hole. The novel air return furnace structure has following beneficial effects: through design of the annular cavity structure and double flow gas channels, high-temperature gas generated by combustion of the furnace body can quickly flow into the pedal base body such that the pedal base body can be heated; fuel is saved; the effect is obvious; and the novel air return furnace structure is simple in structure, convenient in manufacture and high in practicability.

Description

technical field [0001] The invention relates to the furnace design technology, in particular to a novel return air furnace structure. Background technique [0002] When the existing furnace body is heated by burning combustible substances, generally only the upper and middle parts of the furnace body can be heated, and the high-temperature gas will be discharged from the chimney through the smoke. It is difficult to heat the base of the furnace body. If necessary To raise your temperature, you need to increase the amount of combustion to achieve a certain effect through the thermal conductivity of the steel itself. However, this method not only wastes resources, but the effect is not very obvious. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new type of air return furnace structure, which can not only realize the heating of the furnace body itself, but also heat the stepping base of the furnace body, so as t...
