Description

Technical Field

[0001] The present invention relates to the technical field of heating equipment, and in particular to a biomass fuel heating stove and heating equipment thereof for improving heat absorption efficiency. Background Art

[0002] Biomass pellet heating stove is a new generation of environmentally friendly heating equipment. It can replace the traditional coal-fired heating method. Compared with traditional fuels, its biomass pellet fuel has both environmental advantages and economic benefits.

[0003] The current biomass pellet heating stove adopts a negative pressure combustion method. The combustion chamber and the air supply heating chamber are separated. The exhaust gas and dust from the combustion are discharged to the outside through the pipe, and the heating heat is blown into the room by the fan through the heating chamber, thereby realizing the separation of combustion and heating, increasing safety, and being more environmentally friendly and efficient. The furnace core of the combustion chamber of the traditional heating stove is a square furnace box that holds pellet fuel and ignites and burns. It is similar to the bottom of a traditional stove. Due to the excessively fast combustion efficiency of the furnace, the heat is not fully utilized and is discharged along with the exhaust air, resulting in more fuel use, increased costs, and low heating efficiency.

[0004] Patent CN 208418810 U discloses a biomass pellet heating stove, comprising a furnace body, wherein a furnace chamber is arranged in the furnace body, and the characteristic is that a combustion device is arranged in the furnace chamber, a feeding device, a smoke exhaust device and an air inlet connected to the furnace chamber are arranged on the furnace body, a warm air channel is formed between the furnace body and the furnace chamber, a blower driven by a motor is fixedly arranged at the lower end of the furnace body, the blower is connected to the warm air channel, and a warm air outlet is arranged at the upper end of the furnace body.

[0005] The above patent has the advantages of complete combustion, high thermal efficiency, no black smoke generation, good heating effect, safe use, low investment cost, simple structure, reasonable setting, low production cost, etc. However, the above patent cannot solve the problem that the combustion efficiency of the furnace is too fast, resulting in incomplete utilization of heat, which is discharged along with the exhaust air, thereby causing excessive fuel use and increased costs. Summary of the invention

[0006] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to overcome the problems of the current biomass fuel heating stoves, which have too large flames and too fast combustion efficiency during fuel combustion, resulting in rapid heat loss, and thus high fuel usage, increased usage costs and low heating efficiency, and to improve the heat absorption efficiency of the biomass fuel heating stoves and heating equipment.

[0007] The technical solution adopted by the present invention to achieve the above-mentioned purpose is: a biomass fuel heating stove with improved heat absorption efficiency, including a furnace body, a furnace door, a furnace, a combustion device, a smoke exhaust device, an air supply device, and an intelligent control panel, characterized in that: the combustion device includes a furnace core arranged at the bottom of the furnace and a flame arrester placed above the furnace core, the flame arrester is surrounded by side walls, a top plate and a partition, the partition divides the flame arrester into a lower flame arrester chamber and an upper flame arrester chamber, the partition is provided with a plurality of lower flame outlets passing through the partition, the top plate is provided with a plurality of upper flame outlets passing through the top plate, and the lower flame outlets and the upper flame outlets are staggered.

[0008] Furthermore, a plurality of oxygen inlets are evenly arranged on the side wall of the lower flame-blocking chamber, and the oxygen inlets are rectangular, strip-shaped or irregular in shape, and the lower flame outlet and the upper flame outlet are circular, rectangular or irregular in shape.

[0009] Furthermore, the side walls, top plate and partition plate are steel plates and are fixedly connected by welding.

[0010] Furthermore, a supporting device for supporting the flame arrester above the furnace core is fixed to the lower end of the flame arrester, and the supporting device is a cylindrical leg welded to the bottom of the side wall of the flame arrester.

[0011] Furthermore, the air supply device includes a warm air outlet for delivering the warm air in the furnace into the room.

[0012] The present invention also discloses a biomass fuel heating device with improved heat absorption efficiency, including the above-mentioned biomass fuel heating stove with improved heat absorption efficiency, a water tank, a heat dissipation device for dissipating heat to the room, and a connecting device connecting the heat dissipation device and the water tank.

[0013] Furthermore, the heat dissipation device is a radiator, and the radiator includes a heat sink and a heating water circulation pipe.

[0014] Furthermore, the heat dissipation device is a heater, which includes a ventilation motor, a fan and a warm air water circulation pipe.

[0015] Furthermore, the water tank has a double-layer structure, the inner layer is a water cavity, and the outer layer is a warm air cavity, the warm air cavity is connected to the warm air outlet, the connecting device includes a water inlet pipe and a water outlet pipe connected to the water tank, the other ends of the water inlet pipe and the water outlet pipe are respectively connected to the two ends of the heating water circulation pipe and the warm air water circulation pipe, and a water filling port is provided at the upper end of the water tank.

[0016] Furthermore, a water pump for water circulation is provided on the water outlet pipe.

[0017] The beneficial effects of the biomass fuel heating stove and heating equipment for improving heat absorption efficiency of the present invention are:

[0018] The combustion flame in the furnace core enters the flame arrester hood through the lower end of the lower flame arrester chamber. Through the oxygen inlet, the flame arrester hood and the combustion chamber can exchange air, and oxygen flows into the flame arrester hood, thereby making the fuel burn more fully.

[0019] The flame in the lower flame barrier chamber can only enter the upper flame barrier chamber through the lower flame outlet, and then emerge through the upper flame outlet. Since the lower flame outlet and the upper flame outlet are staggered, they will increase the resistance to the diffusion of the flame to the surroundings, limit the shape of the flame, and allow the flame to stay more in the flame barrier hood. At the same time, since the flame barrier hood is made of steel plate, the heat generated by the flame can be absorbed more by the flame barrier hood, thereby making the heat stay in the heating stove longer, slowing down the heat loss and increasing the heating effect of the heating stove.

[0020] The ash particles after fuel combustion are discharged through the lower flame outlet and the upper flame outlet. The two layers of staggered flame outlets increase the collision between the dust particles and the flame hood, making the dust particles evenly broken and smaller, thereby improving the smoke emission effect of the heating furnace.

[0021] The water storage tank is a double-layer structure, the inner layer is a water cavity, and the outer layer is a warm air cavity. The warm air cavity is connected to the warm air outlet. The hot air blown out of the warm air outlet can enter the warm air cavity, thereby heating the water in the water cavity, and then circulate the water in the heating water circulation pipe or the warm air water circulation pipe through the water inlet pipe, the water outlet pipe and the water pump. The radiator dissipates the heat into the room through the heat sink, and the ventilation motor of the heater drives the fan to blow air to the warm air water circulation pipe, thereby dissipating the heat into the room. By connecting a heat sink to the heating furnace, the heat generated by the heating furnace can be dissipated through the heat sink, and the heating furnace and the heat sink are placed in different spaces respectively, thereby separating combustion and heating, and increasing heating safety.

[0022] The present invention has a simple structure, low production cost, high heating efficiency, economy and environmental protection. By adding a flame-blocking cover above the furnace core, the rapid loss of heat caused by excessive flame when the fuel is burned can be avoided, thereby delaying the heating of the heating furnace. At the same time, the ash particles are small and broken evenly, thereby improving the heating effect and smoke emission effect of the heating furnace. BRIEF DESCRIPTION OF THE DRAWINGS
