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...
