Boiler using biomass bales as fuel

Abstract

The invention relates to a boiler using biomass bales as fuel. The boiler comprises a boiler body (1). A bale slideway (13) is arranged in the boiler body (1) and extends backwards from a bale inlet (12). A coke breaking grate (2) is arranged behind the bale slideway (13). A horizontal water jacket (14) located above the bale slideway and the coke breaking grate is arranged in the boiler body. Thefront portion of the horizontal water jacket is spaced from the front wall of the boiler body, so that a lower smoke outlet (17) is formed. A rotary combustion chamber (18) is arranged between the lower smoke outlet and the top wall of the boiler body. A coke combustion settling chamber (22) located behind the rotary combustion chamber is arranged in the boiler body. A plurality of multi-tube heat exchangers (3) are arranged between the coke combustion settling chamber and a boiler body smoke outlet located above the rear wall of the boiler body. According to the boiler, the biomass bales aredirectly used as fuel to achieve combustion, and coke is unlikely to be generated in the combustion process and can be treated conveniently; and the heat efficiency of the boiler is guaranteed, and normal heat supply is ensured. The boiler has a stable using effect, the fuel cost is low, and considerable economic benefits are achieved.

Description

technical field

[0001] The invention relates to a boiler, in particular to a boiler using biomass bundles as fuel. Background technique

[0002] my country is a large agricultural country. For a long time, the treatment method of straw is that part of the straw is used by farmers as fuel for fire or to feed livestock, and most of the straw is directly burned in the field and returned to the field. Although this straw treatment method is relatively simple and beneficial to increase soil fertility, it is not conducive to fire prevention, and straw burning will form serious smog and pollute the environment. In recent years, the country has strictly prohibited the burning of straw in the field. In order not to affect the planting of the next season of crops, our country is promoting the bundling of straw in the field, and then transporting the bales out of the field for other uses. Some of these straw It will be made into pellet fuel, but the cost of pellet fuel made from straw...
