Energy-saving heating furnace with power supply air

Abstract

The invention provides a powering-air-feeding energy-saving heating stove. The powering-air-feeding energy-saving heating stove comprises a stove body. A furnace is arranged in the stove body, a stove bridge is arranged in the furnace, a smoke channel is formed between the furnace and the stove body, an air inlet in the furnace and the smoke channel are partitioned, the smoke channel is connected with a smoke discharging pipe, the smoke discharging pipe is connected with an air feeding pipe of a first air feeding device, and an air discharging pipe of the first air feeding device is connected with a chimney. Preferably, a secondary air feeding device is arranged at the top of the furnace and comprises an annular cavity, a plurality of spraying holes are formed in the inner wall of the cavity, the cavity is connected with an air discharging pipe of a second air feeding device, and an air feeding pipe of the second air feeding device is directly communicated with air. As the air feeding devices are arranged, the negative pressure in the furnace is improved, the air feeding amount, participating in combustion, in the furnace is further increased, the requirement for the chimney of the heating stove is reduced accordingly, and a smoke discharging channel of a building can be used as the chimney. By means of the powering-air-feeding energy-saving heating stove, the structure of the secondary air feeding device is also simplified, and the combustion assisting effect of the secondary air feeding device is improved.

Description

technical field [0001] The invention relates to the field of household heating furnaces, in particular to a dynamic air-supply energy-saving heating furnace. Background technique [0002] In rural areas, there are a lot of straw and wood, if burned at a low level, it will lead to more serious smog weather. These straws and wood are better fuels for domestic heating stoves. Compared with air conditioning, electric heating and gas heating, domestic heating stoves fueled by straw and wood are cheaper and have a better user experience. [0003] At present, there are two main structures of household heating furnaces. One is called the return air furnace, which includes a furnace body. The furnace body is equipped with a furnace. , and then the high-temperature flue gas is discharged into the chimney after passing through the flue. Due to a heat exchange process, it can make full use of the waste heat and save fuel. For example, Chinese patent document CN 201339969 discloses a c...

AI Technical Summary

Problems solved by technology

However, the existing gasifiers all have the problems of complex structure and high production cost, and the effect of the secondary air intake depends on the degree of negative pressure in the furnace, so a higher chimney height and a larger Chimney diameter

[0005] In the prior art, there are requirements for the height and diameter of the chimney, for example, the height must not be less than 2.2 meters, the diameter must be greater than 12 cm, and the number of bending parts cannot be more than 2, otherwise it will cause difficulty in starting a fire, insufficient fuel combustion and after-burning. The problem of smoke entering the room

[0006] The heating furnaces of the above two structures all need to use a chimney for exhausting smoke, and have corresponding requirements for the specifications of the chimney, such as fewer bending parts, sufficient height, and sufficiently thick diameter, otherwise the negative pressure in the furnace will Insufficient, the smoke is easy to flow back into the room, and the combustion is not sufficient

Therefore, in the process of urbanization, these two kinds of heating stoves are not suitable for use in buildings.
