Abstract

The invention relates to a boiler for combusting various biomass fuels so as to generate steam for steam supply and power generation. The invention adopts the following technical scheme that the biomass fuel boiler is characterized by comprising a steel frame, wherein a hearth is arranged on the steel frame, a boiler barrel is arranged above the hearth, a cross beam type chain grate is arranged atthe lower part of the hearth, the cross beam type chain grate is directly supported on the steel frame, a slag discharging and an ash discharging device is installed on the lower surface of the crossbeam type chain grate, a horizontal flue and a tail flue are arranged at the outlet of the hearth, at least one feeding device and a spraying device are uniformly arranged in the width direction of the front edge of the hearth. By adopting the scheme, the novel biomass fuel boiler has the advantages that the defects in the prior art are overcome, and the novel biomass fuel boiler is low in investment cost, short in construction period and high in combustion efficiency.

Description

technical field [0001] The invention relates to a boiler which burns various biomass fuels to generate steam for steam supply and power generation. Background technique [0002] With the continuous development of the economy and the continuous improvement of people's living standards, the energy supply is becoming increasingly tense. Through the development and utilization of biomass resources that are rich in resources, highly renewable, and conducive to improving the environment and sustainable development, it is a solution to the energy crisis and protect the environment. effective way. In recent years, biomass power generation has been developed to a certain extent. [0003] Biomass power generation mainly uses agricultural, forestry and industrial wastes as raw materials and converts them into clean energy forms such as electricity. Using biomass to incinerate in boilers, the steam produced is used for power generation or steam supply, which has both good social benef...
