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.

氣化發電過程包括三個方麵，一是生物質氣化，把固體生物質轉化為氣體燃料;二是氣體淨化，氣化出來的燃氣都帶有一定的雜質，包括灰份、焦炭和焦油等，需經過淨化係統把雜質除去，以保證燃氣發電設備的正常運行;三是燃氣發電，利用燃氣輪機或燃氣內燃機進行發電，有的工藝為了提高發電效率，發電過程可以增加餘熱鍋爐和蒸汽輪機。

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.

生物質氣化發電技術是生物質能利用中有別於其他可再生能源的獨特方式，具有三個方麵特點：

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

1、是技術有充分的靈活性，由於生物質氣化發電可以采用內燃機，也可以采用燃氣輪機，甚至結合餘熱鍋爐和蒸汽發電係統，所以生物質氣化發電可以根據規模的大小選用合適的發電設備，保證在任何規模下都有合理的發電效率。這一技術的靈活性能很好地滿足生物質分散利用的特點;

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、是具有較好的潔淨性，生物質本身屬可再生能源，可以有效地減少CO2、SO2等有害氣體的排放。而氣化過程一般溫度較低(大約在700-900攝氏度)，NOx的生成量很少，所以能有效控製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、是經濟性，生物質氣化發電技術的靈活性，可以保證該技術在小規模下有效好的經濟性，同時燃氣發電過程簡單，設備緊湊，也使生物質氣化發電技術比其他可再生能源發電技術投資更小，

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,
