Description

Hollow ring bile multi-stage air supply advanced biomass cooking stove

technical field

The utility model relates to a multi-stage air-supply high-grade biomass cooking stove with a hollow ring gall, in particular to a cooking stove using biomass fuel for cooking.

Background technique

Because biomass (such as straw, sticks, corncobs, etc.) is cheap and widely available, it is still the fuel for cooking that is usually used by farmers in cities and towns. However, because the moisture content of straw is not easy to control, especially in rainy days and During the dog days, the straw is prone to mildew and moisture, which is not conducive to combustion. Now the straw is processed into biomass briquette fuel, but this fuel is different from coal, and its combustion value is lower than that of coal. If a coal-fired furnace is used, the biomass fuel Advantages cannot be brought into full play, and its combustion efficiency will be reduced.

Utility model content

The purpose of the utility model is to provide a high-grade biomass cooking stove with hollow ring bile multi-stage air supply, which overcomes the above-mentioned defects, and provides a simple, cheap and easy-to-operate biomass fuel cooking stove.

The utility model is a multi-stage air-supply high-grade biomass cooking stove with a hollow ring gallbladder, which comprises: a furnace shell, an insulating layer, a fire grate, a fire ring, a furnace gallbladder, a hollow ring gallbladder and a blower interface, and the heat preservation layer is closely attached to the furnace shell Setting, the hollow ring is inside the insulation layer, the furnace is concentric with the hollow ring, and there are more than a dozen air inlet holes on the furnace, which lead into the furnace. The furnace is small at the top and large at the bottom, similar to the shape of a thermos bottle. There is an air inlet connected to the outside world and a blower interface. A grate is installed in the furnace at the upper end of the air inlet. The top of the furnace is inside the furnace shell and has a longitudinal distance from the furnace shell. A fire stop is installed on the top of the furnace. Ring, a gas outlet is opened on the side wall of the furnace shell at the top of the furnace;

The utility model is a multi-stage air-supply high-grade biomass cooking stove with a hollow ring bile, wherein: the stove is equipped with a blower interface.

The utility model relates to a multi-stage air-supply high-grade biomass cooking stove with a hollow ring gall, wherein a hollow ring gall is installed inside the stove.

The utility model relates to a multi-stage air-supply high-grade biomass cooking stove with a hollow ring gallbladder, wherein: the furnace gallbladder has air inlet holes.

The biomass molding fuel cooking furnace of the utility model has the following advantages:

1. It can give full play to the advantages of biomass fuel, so that the biomass fuel can be fully burned;

2. It can be used as a cooking stove for cooking. When not in use, it can be sealed like an ordinary briquette stove, and there is no need to repeatedly ignite it when in use;

3. The fuel price of the hollow ring bile multi-stage air supply high-grade biomass cooking stove is cheap, and no sulfide is produced after combustion, which is conducive to environmental protection and is a new type of sustainable energy;

4. The fuel of the hollow ring bile multi-stage air supply advanced biomass cooking stove is processed from waste biomass (such as straw, sticks, corncobs, etc.), so even if the waste is utilized, it can obtain a clean It is a renewable fuel that benefits the country and the people.
