Tibetan energy-saving gasifier
Technical field
[000 1] The utility model relates to the field of civil stoves, in particular to a Tibetan energy-saving gasifier.
technical background
[0002] At present, domestic solid fuel stoves in Tibetan areas in China mainly use traditional direct-fired stoves, which have poor heat dissipation effect.
A large number of combustible materials and heat are discharged with excess air, and only a part of heat is conducted to the room through the furnace cover, resulting in most of the heat being white.
Waste in vain. There are also some heating pipes or sealed water bags in the furnace, but the structure is complex, the heat transfer efficiency is low and the production cost is high.
Energy saving is not enough.
[0003] According to the present situation of Tibetan areas in China, it is urgent to develop an efficient furnace with simple structure, convenient use, energy saving and environmental protection.
With.
Content of utility model
[0004] The technical problem to be solved by the utility model is to provide an efficient energy-saving and environment-friendly device with simple structure and convenient use.
Efficient stove.
[0005] The specific technical scheme of the utility model is as follows:
[0006] Tibetan energy-saving gasifier consists of three parts: air inlet and ash discharge area, combustion chamber and exhaust area.
[0007] The air inlet and ash outlet area is located at the bottom of the furnace body and includes a primary air inlet cavity 3, a secondary air inlet cavity 4, an ash outlet drawer 5 and a first inlet.
Secondary air inlet 1 1, secondary air inlet 12, base 14. The base 14 is arranged at the bottom of the furnace body to support the whole furnace body.
Body. The ash discharging drawer 5 is arranged in the secondary air intake cavity 4, and can be drawn out from the secondary air intake cavity 4 to facilitate ash discharging.
The ash hopper 5 is provided with a primary air inlet hole 1 1, which directly communicates with the furnace body; Paddle wheels are arranged on the ash drawer 5.
The button 15 is used to adjust the opening and closing of the primary air inlet 1 1. The secondary air inlet 12 is arranged on the air inlet cavity 3. place
A fence 13 is arranged at the upper part of the secondary air intake cavity 4 opposite to the ash discharge drawer 5, which is convenient for air to enter the combustion chamber and burn ash at the same time.
Dust falls into the ashtray 5.
The combustion chamber includes a primary combustion zone 1, a secondary combustion zone 2, a secondary air inlet device 9, a baffle 8 and a furnace door 6.
[0009] The furnace door is arranged at the front side of the combustion chamber for adding solid fuel. The primary combustion zone 1 is set at
The bottom of the combustion chamber is connected with the primary air intake cavity 3. Baffle 8 is arranged in the combustion chamber to divide the air from outside the furnace into.
Two air streams, one from the primary air inlet 1 1, enter the primary combustion zone 1 through the primary air inlet cavity 3 and participate in the combustion of solid fuel;
Another airflow from the secondary air inlet 12 directly enters the secondary combustion zone 2 through the secondary air inlet device 9 via the secondary air inlet chamber 4,
Participate in secondary combustion. Now the solid fuel is placed at the bottom of the main combustion zone 1 for combustion. Set at the top of primary combustion zone 1.
The secondary air inlet device 9 has a conical lower part and a cylindrical upper part, and the side wall is provided with a secondary passage.
Stomata 10. Primary combustion zone 1 flue gas containing combustible substances such as carbon monoxide produced by incomplete combustion of solid fuel.
After being collected by the secondary air intake device 9 and mixed with air, it enters the secondary combustion zone 2 for full combustion. Secondary combustion zone
2 is arranged at the top of the combustion chamber for burning flue gas.
[00 10] The smoke exhaust area includes chimney 7 and flue ash outlet 16. A chimney 7 is arranged at the top of the secondary combustion zone 2 for
Smoke exhaust; The flue ash outlet 16 is arranged at the bottom of the secondary combustion zone 2, opposite to the chimney 7.
[00 1 1] When the utility model is used, first open the primary air inlet 1 1 and the secondary air outlet 12, and then light it at one time.
For the solid fuel in 1 combustion zone, the primary air inlet 1 1 is closed after the furnace body is heated up, so that the solid fuel in the primary combustion zone 1 cannot be discharged.
Full combustion produces combustible smoke. Combustible flue gas is collected by the secondary air intake device 9 and mixed with air to enter the secondary air.
The combustion zone 2 is completely burned, and the flue gas is discharged through the chimney 7. The purpose of setting two combustion chambers is to ensure the full combustion of fuel.
On the premise that as little heat passes through the chimney 7 as possible.
[00 12] beneficial effects:
[00 13] The Tibetan energy-saving gasifier of the utility model has the following three beneficial effects: First, the primary combustion zone is 1.
Internal relative lack of oxygen, slow combustion of solid fuel, can save fuel; Second, the secondary combustion zone 2 has strong combustion and good heat dissipation, which can be
Ensure the effect of heating cooking; Thirdly, due to the high speed of secondary combustion, the utilization rate of introduced air can be improved and excess air can be reduced.
Heat loss during discharge. The test shows that the greenman blackness of the utility model is below the first level, and the ring is good.
Ensure the effect.
