Abstract

The invention relates to a boiler which can combust all kinds of biomass fuel to generate steam and is used for supplying steam and generating electricity. The invention adopts the following technical scheme that: a biomass fuel boiler is characterized by comprising a steel frame and a hearth; wherein the hearth is arranged on the steel frame; a boiler barrel is arranged over the hearth; a crossbeam-type chain grate stoker is arranged on the lower part of the hearth and is directly supported on the steel frame; a slag-out and ash-out device is arranged below the crossbeam-type chain grate stoker; an outlet of the hearth is provided with a horizontal flue and a tail flue; and the at least one set of feed device and a spray seeding device are arranged in front of the hearth along the width direction uniformly. Due to the adoption of the technical scheme, the defect in the prior art is overcome; and a novel biomass fuel boiler is provided and has the advantages of low investment cost, short construction cycle and high 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...
