With biomass (crop straw, plant straw, wood waste, etc.) as the carrier, the energy generated by biomass is biomass energy. Biomass energy is an energy form in which solar energy is stored in organisms in the form of chemical energy. It is an energy carried by biomass. It comes directly or indirectly from the photosynthesis of plants. Among various renewable energy sources, biomass is unique. It is stored solar energy, and it is the only renewable carbon source, which can be converted into conventional solid, liquid and gaseous fuels.

According to the energy news on March 12, 2007, the title is "biomass boilers will replace coal-fired boilers", and the full text is as follows: "on March 12, it was learned from Shenyang Environmental Protection Bureau that an environmental friendly and energy-saving biomass boiler using straw as raw material will replace 200 coal-fired boilers in the city.

On the same day, the reporter saw in a villa in Qipanshan scenic spot that a boiler, such as a small container, had a high flame in the furnace. According to the staff responsible for tracking the technology of this project, since the trial operation of the boiler on the fifth day of the first month, the effect has been very good. The fuel is wood, there is no pollution, and the calorific value is equal to that of burning coal.

According to reports, biomass boilers have a wide range of raw materials, as long as they are wooden idle materials through photosynthesis, such as rice husks, sunflower seed husks, sorghum stalks, corn stalks, bean stalks, etc. after being pressed into columnar granular fuel by a special molding machine at high temperature and high pressure, they can generate sufficient heat into a specially made boiler, and the slag they produce can still be used as potassium fertilizer to supplement crops. According to the relevant person in charge of Shenyang Environmental Protection Bureau, biomass energy raw materials can achieve "0" emissions of sulfur dioxide and carbon dioxide. It is understood that from this year, Shenyang will vigorously promote biomass boilers and strive to complete the transformation of 200 boilers throughout the year. We will also carry out desulfurization and dust removal projects for several major power plants and nearly 10 units in the city. The existing boilers of less than 10 tons will also be demolished, and water source heat pumps and biomass energy will be used for heating. "

China is rich in biomass energy resources, with theoretical biomass energy resources of about 5 billion tons.

The relevant departments of our government attach great importance to the utilization of biomass energy, and have listed the research and application of biomass energy utilization technology as a key scientific and technological research project in four national five-year plans, and carried out the research and development of biomass energy utilization technology.

application area

Biomass energy boilers use biological solidified body as fuel (such as using sawdust, straw, hemp stalk, wood waste, fruit shell, etc.), which is clean and environment-friendly. Compared with coal-fired boilers, biomass fuel costs are low, significantly reducing operating costs. The boiler adopts a number of new technologies, which have the characteristics of atmospheric pressure, smoke-free and fast temperature rise. It is a new type of environmental protection boiler.

Biomass boilers are widely used in petroleum, chemical, pharmaceutical, textile printing and dyeing, light industry, building materials, hospitals, leather goods production enterprises, large hotels, schools and service enterprises in areas with sufficient biomass energy
