Biomass gasification direct-fired multifunctional energy-saving furnace

technical field

The utility model relates to an energy-saving furnace, in particular to a biomass gasification direct-fired multifunctional energy-saving furnace, which belongs to household stoves.

Background technique

At present, rural areas in the suburbs of Beijing, especially farmers in remote mountainous areas, basically use coal, liquefied petroleum gas, and firewood as the main fuels for their daily life. In view of the rising coal price and liquefied gas price in the current market, farmers are overburdened. Moreover, the current fuel and traditional combustion methods not only consume a lot, but also cause heavy smoke billowing during combustion, which seriously pollutes the air and causes great harm to environmental sanitation.

Utility model content

The purpose of this utility model is to provide a kind of natural agricultural and forestry waste materials such as firewood, mountain firewood, branches and stalks to burn, and at the same time, generate gasification and carry out secondary combustion, so that the fuel and smoke can be fully burned, and the burning time can be reduced. It can be used for cooking, cooking, boiling water, heating, heating, and other cooking and heating dual-purpose biomass gasification direct-fired multifunctional energy-saving stoves.

The purpose of this utility model is achieved by the following technical solutions, which include a furnace body, a furnace cover, a furnace door, a chimney outlet, and a water jacket. A honeycomb coal furnace tile is arranged in the water jacket at the upper half of the furnace body, and a burner is arranged in the furnace tile. , The lower part of the furnace body is provided with a generator and an air distribution master, and the generator and the air distribution master cooperate up and down.

The combustion aid is a double-cylinder type whose upper edge is fixed, the outer cylinder is short, the inner cylinder is long, and the walls of the inner cylinder are provided with small holes arranged in an orderly manner.

The generator is an open drum type, two circles of air inlet holes are arranged at the bottom of the drum, and a square upper cover with a round hole in the middle is placed on the top of the drum, and the burned firewood is placed in the drum.

The air distribution system is in the shape of a square box, with inner and outer circular air inlet pipe walls in the middle, the gap in the inner air inlet pipe wall is connected to an air inlet pipe, and the gap in the outer air inlet pipe wall is connected to another air inlet pipe wall. The pipes are connected; a plurality of air outlet holes are arranged along the upper panel inside the inner air inlet pipe wall, and a plurality of air outlet holes are evenly distributed along the circumference along the upper panel inside the outer air inlet pipe wall; The damper damper controls which intake duct the air enters. The air outlet hole on the air distribution master communicates with the air inlet hole of the generator.

The outlet of the chimney is connected with a T-shaped smoke exhaust chimney, and the T-shaped smoke exhaust chimney has two outlets, one is connected to the hanging kang, and the heat in the furnace is introduced into the cavity of the hanging kang, and the other is connected to the outside, and the remaining CO is discharged outside; A flue ram handle is respectively provided at two adjacent outlets outside the T-shaped smoke exhaust chimney, which are respectively connected with the gate plates in the smoke exhaust chimney.

The left, right, and rear middle parts of the furnace body are respectively provided with a row of air supply holes, which are set for the secondary air supply of the burner, which is practical and does not affect the overall appearance of the furnace shell; A pullable fire-sealing board is used for night-time fire-sealing when burning briquettes.

The furnace body is composed of double-layer iron plates filled with thermal insulation, heat-resistant and flame-retardant mineral wool in the middle.

The principle of use is as follows:

After the upper end of the firewood in the generator is ignited, until the firewood is burned out, an appropriate amount of wind must be distributed in the generator. When distributing air, by moving the position of the damper baffle in the air distributing process left and right, that is, first supply air to the middle of the generator, and then supply air to the surroundings of the generator, so as to ensure a successful ignition until the fuel is completely burned; The size of the burner flame can be regulated by controlling the air supply. A row of air supply holes are respectively arranged in the left, right and rear middle of the furnace body, which are set for the secondary air supply of the burner.

When burning the Kang Kang in winter, the shutter leading to the Kang Kang cavity is opened by the flue shutter handle, and the shutter of the other flue shutter handle is closed (leading to the outdoor flue) simultaneously. When the kang is not burned in summer, the shutter leading to the hanging kang is closed, and the shutter leading to the outdoor flue is opened simultaneously.

In order to ensure the cleanliness and sanitation of the steam used in the steamer, it cannot be mixed with heating water. Therefore, when using the steamer, the cut-off door for entering and leaving the heating must be closed, and the water in the water jacket of the furnace chamber must be drained through the drain cut-off door. , and then inject clean new water (approximately: 3.5Kg) from the tray to use the steamer.

Such as burning briquettes, just take out the burner.

The utility model has the advantages of:

1. It is easy to get firewood and the fuel cost is low.

It mainly uses natural materials such as chopping wood, mountain firewood, stalks, corn cobs and other natural materials as fuel, which has remarkable energy-saving effect and is economical.

2. Strong firepower, long burning time and full combustion.

With the same amount of firewood, the burning time of this energy-saving stove is nearly three times longer than that of ordinary stoves.

3. Good environmental protection effect.

Due to the good gasification, all the smoke is re-combusted by the burner, the firepower is more intense, and there is basically no external smoke during the combustion process, which has no pollution to the atmosphere and meets the requirements of the Beijing DB11/139-2002 emission standard.

4. Simple operation.

Just fill in the firewood once and light it. After adjusting the damper, you can sit on the pot and sit on the pot. Stir-frying can be carried out while steaming steamed buns and steaming rice. If the firewood filled at one time is not enough, you can add firewood again.

5. Safety.

The absolute temperature of the surface around the furnace body is not more than 25°C. Because the chimney is installed outdoors, the harm of carbon monoxide to the human body can be prevented.

6. This energy-saving furnace mainly burns firewood, and can also burn honeycomb coal.
