Secondary air intake type energy-saving kitchen range core

Abstract

The invention provides a secondary air intake type energy-saving kitchen range core. The secondary air intake type energy-saving kitchen range core is composed of the combination of a seat (1), an inner tank (3) and a flame bridge (3); the seat (1) is of a structural shape that a barrel body (5) of which one end is equipped with an external opening (4) is fixedly connected to a bottom plate (6), a kitchen range hole (7) is formed in the inner middle of the circumference of the barrel body, and an annular secondary air intake hole (8) is formed between the barrel body and the kitchen range hole; the inner tank is of a structural shape of a tapered barrel body; an annular skirt plate (10) is connected to the top end of the tapered barrel body; an inner opening (9) is formed in one side of the whole barrel body, and one to four rows of air return holes (11) are formed in the upper section of the tapered barrel body; the seat, the inner tank and the flame bridge are in fit joint by a manner that the inner tank is positioned in the barrel body of the seat, and the flame bridge is positioned on the kitchen range hole in the seat. The secondary air intake type energy-saving kitchen range core is simple in structure, easy to be manufactured and mounted, and obvious in secondary air intake effect, and enables sufficient burning of firewood and coal, and the thermal efficiency is up to 40 to 50%.

Description

technical field [0001] The invention belongs to the technical field of stove core structure of household coal-burning and wood-burning stoves. Background technique [0002] Existing domestic coal-fired and wood-fired stoves are usually connected directly to the furnace body by the stove core, and the air is only taken in from the stove mouth and the furnace door. The thermal efficiency of the stove with this old structure is extremely low, and a large amount of firewood and coal is wasted; Recently, a kind of wood-coal stove with secondary air intake has also appeared. It mainly uses an additional air return ring on the furnace, and at the same time is equipped with a vaporization device on the furnace door to form a secondary air intake to accelerate the combustion of firewood and coal. Full combustion, but the disadvantage of this structure is that it is not conducive to the transformation and utilization of the current household stoves. It is necessary to purchase a new s...

[0002] Existing domestic coal-fired and wood-fired stoves are usually connected directly to the furnace body by the stove core, and the air is only taken in from the stove mouth and the furnace door. The thermal efficiency of the stove with this old structure is extremely low, and a lot of firewood and coal are wasted; Recently, a kind of wood-coal stove with secondary air intake has also appeared. It mainly uses a return air ring on the furnace, and at the same time, a vaporization device is installed on the furnace door to form a secondary air intake to accelerate the combustion of firewood and coal. Full combustion, but the disadvantage of this structure is that it is not conducive to the transformation and utilization of the current household stoves. It is necessary to purchase a new stove and discard the old stove. Moreover, the device and structure of the return air are not very reasonable, so that the secondary air intake is not suitable. Sufficiently, the thermal efficiency of wood stoves can only reach 10-30% usually, and there is still a waste of fuel resources
