Description

Gasification wood burning hot water stove

technical field

The invention relates to a stove for cooking with wood, in particular to a gasification type hot water stove for burning wood that can generate a large amount of hot water when cooking with wood.

Background technique

At present, domestic hot water supply mainly includes gas water heaters, electric water heaters, and solar water heaters. Due to the energy crisis, gas and electricity prices have risen sharply. Although the prices of the first two types of products are not too high, they need to pay a lot of money after installation. Funds, although solar water heaters are a one-time investment, they have disadvantages such as high price, low hot water supply in winter, and inability to provide hot water in rainy weather. Due to the limited purchasing power of farmers, the above three types of products cannot be popularized in the vast rural areas. The coal fire in the water tank that uses coal as fuel can provide a certain amount of domestic hot water for cooking. However, with the rise of coal prices, most farmers use local materials to cook with plant straws and branches, and they have no access to hot water all year round. , not only cannot solve the problem of bathing, even in the winter when dripping water freezes, there is no domestic hot water for washing hands and vegetables. Farmers hope to live a well-off life, and the most basic feature of a well-off life is the supply of domestic hot water. Make a general survey of domestic and foreign markets, also do not have a kind of stove that can produce hot water while burning wood for cooking.

Contents of the invention

The object of the present invention is to provide a kind of gasification type wood burning hot water stove which is simple in structure, low in price, can be used for cooking, and can also produce a large amount of hot water.

In order to achieve the above purpose, the technical solution we adopt is: the stove has two combustion chambers up and down: the stove inner core, the fire grate, and the firewood inlet door jointly form a non-closed space as the first combustion chamber; the stove outer core and the upper part of the stove shell , the sealing plate, and the pot ring together form a non-closed space that is the second combustion chamber; the grate, the ground, the bottom of the stove shell, and the primary air inlet/slag discharge sliding door jointly form a non-closed space that is the primary air inlet distribution room. The upper part of the stove inner core, the stove outer core and the sealing plate jointly form a non-enclosed space, which is the secondary air inlet distribution room; the stove inner core, the secondary air intake pipe jointly form a non-enclosed space, which is the secondary air intake channel , the upper part of the secondary air intake channel is connected with the secondary air intake distribution chamber, and the lower part is communicated with the atmosphere through the primary air intake distribution chamber, or directly communicated with the atmosphere; the upper part of the first combustion chamber is provided with a secondary air intake hole or gap; waste heat The absorber is installed in the peripheral part of the second combustion chamber, and keeps a certain distance from the stove shell; the sealing plate is installed on the upper part of the insulation material and fixed together with the stove shell, and the lower part of the waste heat absorber is fixed on the sealing plate, and its upper and lower The two ports are respectively communicated with the insulated water tank or the holes in the wall of the water tank through pipes; a waste heat absorber is also installed on the exhaust duct.

The invention adopts the structure of primary gasification and secondary air supply, which can fully burn the firewood, not only improves the thermal efficiency of the firewood, but also reduces the black smoke pollution of the atmosphere.

The invention utilizes the multiple recovery structure of waste heat, which can not only provide a large amount of domestic hot water and heating heat, but also reduce atmospheric thermal pollution.

The present invention uses plant straw as fuel, which is the utilization of biomass energy in renewable energy and the utilization of solar energy in a broad sense. It not only prevents the air pollution caused by someone burning straw in the field, but also saves a lot of coal, gas and electricity resources. , is conducive to the sustainable development of our country and is supported by national policies.

The invention has the advantages of simple structure, low cost and complete functions, and can provide a large amount of hot water and heating heat throughout the day while cooking, and is very popular with farmers and has broad market prospects.
