Description

High-efficiency, energy-saving and environment-friendly wood-coal dual-purpose gasifier

technical field

The utility model belongs to a stove, in particular to a stove which uses straw, firewood or coal as fuel and is used for cooking, heating and bathing in farmers' families.

Background technique

Stoves that burn straw and various types of firewood, as well as coal-fired stoves are widely used, especially in vast rural areas, where they are used by almost every household. It has the advantages of wide range of fuel, low cost, and easy operation, and has been widely used by people for a long time. However, they either only burn coal but not straw firewood, or they can only burn straw firewood but not coal, and consume more fuels such as coal or firewood, have low thermal efficiency and pollute the environment. For a long time, people have proposed many improved technologies for coal-fired stoves and straw gasification or semi-gasification combustion technologies, trying to save energy and develop and utilize renewable energy, which is more environmentally friendly, and many more effective ones have emerged. technology and products. However, it still needs continuous improvement and improvement to make it more efficient, energy-saving and environmentally friendly.

Utility model content

The purpose of the utility model is to solve the above-mentioned technical problems, and propose a high-efficiency, energy-saving and environment-friendly dual-purpose gasifier for firewood and coal. The fuel of the stove is easy to obtain, the operating cost is low, the operation is simple, the stove is more efficient, more energy-saving and more environmentally friendly.

The purpose of this utility model is solved by the following technical solutions: a high-efficiency, energy-saving and environment-friendly wood-coal dual-purpose gasifier is provided with a furnace body, a filling port, a water jacket, and a hot water pipe, and it is characterized in that: the furnace body is made of It consists of a combustion chamber, a furnace mouth, a stove mouth and a heated body. The combustion chamber, the furnace mouth, and the stove mouth are located at the lower part of the furnace body, and the lower part of the combustion chamber is provided with a fire outlet. Above the furnace mouth; the fire outlet passes through the furnace mouth and communicates with the heating body located on the upper part of the furnace body. Water jackets are provided on the walls of the combustion chamber, the fire outlet and the heating body, and are connected to each other. The hot water pipe connected with the water jacket, the middle of the heating body is the flue; the bottom of the combustion chamber is the grate; the upper part of the heating body is provided with a water outlet, and the lower part of the combustion chamber is provided with a water return port.

The supplementary scheme that the utility model further improves and implements is:

An oxygen increasing pipe A is arranged at the front of the combustion chamber, and an oxygen increasing pipe B is arranged on the side of the fire outlet.

A filling port is provided on the upper part of the combustion chamber, and a slag outlet is provided below the grate.

A flap is provided in the exhaust duct.

A baffle is provided on the upper part of the combustion chamber.

The utility model is provided with a separate combustion chamber. By setting a fire outlet at the high-heat and fully-combusted part of the lower part, combustible gases such as high-temperature flames and carbon monoxide enter the furnace mouth and the heated body, and then increase oxygen through the oxygen-increasing tube to generate High temperature flame. Because the upper part of the combustion chamber is not ventilated, the fuel is not fully burned inside, and a large amount of combustible gas is continuously produced, which is sent out from the fire outlet, thereby generating a gasification process and efficient combustion. The utility model has the advantages of reasonable structure, sufficient combustion, high thermal efficiency, less exhaust gas emission, good environmental protection effect and energy saving.
