Electricity generation by gasification is an efficient means of dispersed utilization of biomass energy, more suitable for China's current economic level and development status. Chinese biomass has a good technical foundation. As long as secondary pollution is resolved, it will have the conditions to compete with other conventional power generation technologies. In order to develop and promote biomass gasification technology as soon as possible, three aspects of work should be carried out at present: firstly, research on tar processing technology to completely eliminate secondary pollution, secondly, improve gasification power generation technology and systems for overall improvement; energy efficiency and further reduce electricity production costs; The third is to formulate guarantee policies for encto explore the application of electricity production technology by biomass gasification.
Biomass refers to various organisms formed by photosynthesis, including all animals, plants and microorganisms. Biomass energy is the energy form of solar energy stored in biomass as chemical energy. It has always been one of the important energy sources for human survival.
Biomass gas purification refers to the use of rapid condensation and condensation. purification of the suspension. Technical process for adsorbing and condensing wood tar in straw gas. The key to purification of biomass straw gas lies in the agglomeration of fine tar dust particles. The developed YN01 biomass gas purifier, the prototype operation test shows that it has overcome the common defects of biomass gas purification systems.biomass straw such as large initial investment, complex equipment and low purification efficiency, and it has high practical value and promotion and application prospects. .
Biomass energy has always been one of the important energy sources for human survival. In global energy consumption, biomass energy accounts for 14% of total energy consumption. From an environmental perspective, the development of biomass energy can help reduce the greenhouse effect and reduce global environmental pollution such as acid rain, acid fog and dust. The high-quality use of biomass energy has become one of the most developed renewable energy technologies in recent years.
Biomass gasification is a major conversion technology for high-quality utilization of biomass energymass. It is an energy conversion process that burns and reduces biomass raw materials into an anoxic state. into high quality fuel gas. However, the tar produced during the pyrolysis and gasification process will cause blockage, pollution and corrosion of pipelines, stoves, gas turbines, etc. Therefore, the produced biogas needs to be properly purified, but the investment in biogas purification equipment is relatively large. The purification effect is not ideal, which makes the purification system have a short lifespan, poor economic benefits, and is not suitable for popularization and application. Therefore, biomass gas purification has become the main factor limiting the commercialization of biomass pyrolysis and gasification technology, and is an important problem that urgently needs to be solved in the field.of biomass energy science at home and abroad.
