A kind of smoldering furnace and smoldering system

Abstract

The invention provides a smoldering furnace and a smoldering system, which belong to the field of combustion equipment. The smoldering furnace includes a furnace body and an upper cover. The furnace body is provided with a cavity. The upper cover is arranged on the top of the furnace body to seal the cavity. There is a stove head; the top of the side wall of the furnace body is provided with a feed inlet and a chimney, the bottom end of the side wall of the furnace body is provided with an ignition port and an air inlet, the bottom wall of the furnace body is provided with an ash discharge port, and the ignition port is provided with an igniter. The cavity is provided with a grate and an air supply mechanism. The smoldering system includes a feeding device and a smoldering furnace. The feeding device includes a storage bin and a delivery pipeline. One end of the delivery pipeline communicates with the storage bin, and the other end of the delivery pipeline communicates with the feed inlet. The structure of the smoldering furnace is simple, the oxygen can fully contact with the fuel, the operation is convenient and the combustion efficiency is higher. The smoldering system only needs to store the fuel in the storage bin in advance, and then it can automatically complete the transportation and combustion, and the operation is convenient and quick.

Description

technical field [0001] The invention relates to the field of combustion equipment, in particular to a smoldering furnace and a smoldering system. Background technique [0002] At present, there are a large number of straw burning phenomena in rural areas of our country. This phenomenon not only pollutes the environment, but also wastes biomass energy, a valuable energy source. Straw can be made into a kind of biomass pellet fuel, which is convenient to produce, simple to use and high in economy, and is suitable for the vast rural people in our country. Biomass cooking stove is a stove that uses biomass pellet fuel for cooking. Each farmer only needs 3-5 kg ​​of biomass pellet fuel per day to solve all-day living energy (cooking, heating, showering), and production Material pellet fuel can burn like liquefied petroleum gas, which can completely replace traditional firewood stoves and replace liquefied petroleum gas, thus completely changing the smoky lifestyle in rural areas...

AI Technical Summary

Problems solved by technology

[0004] (1) Low gasification efficiency

At present, the efficiency of many smoldering furnaces on the market is 20%, which does not meet the national standard, which not only causes waste of energy, but also poses a threat to the safety of users.

[0005] (2) Complex structure and inconvenient operation

One is the process of converting straw particles into flue gas, which requires an absolutely sealed space, plus a state of continuous constant temperature heating, so as to form combustible smoke. The airtightness of the space and the constant temperature of the temperature are difficult to control. Many users It is reported that 9 times out of 10 times it was used unsuccessfully, and it finally ignited, and it also made my head feel disheartened.

The second is the treatment of tar. To separate the tar, it is necessary to use a tar separator. However, the equipment is expensive and farmers cannot afford to install it. Therefore, the tar cannot be disposed of in time, and parts need to be replaced after a period of use.

[0006] (3) The durability is not high

Biomass gasifiers are mainly used in rural areas, so the structure is too complicated

The daily operation cost of maintenance and staff is relatively high, which is not conducive to the overall promotion
