The basic principle of biomass gasification power generation technology is to convert biomass into gas, and then use the combustible gas to promote gas-fired power generation equipment for power generation. It can not only solve the problem that biomass is difficult to burn and disperse, but also can give full play to the advantages of gas power generation technology with compact equipment and less pollution, so it is one of the most effective and clean utilization methods of biomass energy.

气化发电过程包括三个方面，一是生物质气化，把固体生物质转化为气体燃料;二是气体净化，气化出来的燃气都带有一定的杂质，包括灰份、焦炭和焦油等，需经过净化系统把杂质除去，以保证燃气发电设备的正常运行;三是燃气发电，利用燃气轮机或燃气内燃机进行发电，有的工艺为了提高发电效率，发电过程可以增加余热锅炉和蒸汽轮机。

The gasification power generation process includes three aspects: first, biomass gasification to convert solid biomass into gas fuel; second, gas purification. The gasified gas contains certain impurities, including ash, coke and tar, which need to be removed through the purification system to ensure the normal operation of gas-fired power generation equipment; The third is gas-fired power generation, which uses gas turbine or gas internal combustion engine for power generation. In some processes, in order to improve the power generation efficiency, waste heat boiler and steam turbine can be added in the power generation process.

生物质气化发电技术是生物质能利用中有别于其他可再生能源的独特方式，具有三个方面特点：

Biomass gasification power generation technology is a unique way of biomass energy utilization, which is different from other renewable energy

1、是技术有充分的灵活性，由于生物质气化发电可以采用内燃机，也可以采用燃气轮机，甚至结合余热锅炉和蒸汽发电系统，所以生物质气化发电可以根据规模的大小选用合适的发电设备，保证在任何规模下都有合理的发电效率。这一技术的灵活性能很好地满足生物质分散利用的特点;

1. Due to the flexibility of technology, internal combustion engine, gas turbine and even waste heat boiler and steam power generation system can be used for biomass gasification power generation. Therefore, appropriate power generation equipment can be selected according to the size of biomass gasification power generation to ensure reasonable power generation efficiency under any scale. The flexible performance of this technology can well meet the characteristics of biomass decentralized utilization;

2、是具有较好的洁净性，生物质本身属可再生能源，可以有效地减少CO2、SO2等有害气体的排放。而气化过程一般温度较低(大约在700-900摄氏度)，NOx的生成量很少，所以能有效控制NOx的排放;

2. Biomass is a renewable energy, which can effectively reduce the emission of CO2, SO2 and other harmful gases. However, the gasification process generally has low temperature (about 700-900 ℃) and little NOx generation, so it can effectively control NOx emission;

3、是经济性，生物质气化发电技术的灵活性，可以保证该技术在小规模下有效好的经济性，同时燃气发电过程简单，设备紧凑，也使生物质气化发电技术比其他可再生能源发电技术投资更小，

3. The flexibility of biomass gasification power generation technology can ensure the effective and good economy of the technology in small scale. At the same time, the gas power generation process is simple and the equipment is compact, which also makes the investment of biomass gasification power generation technology smaller than other renewable energy power generation technologies,
