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(fā)電過(guò)程包括三個(gè)方面，一是生物質(zhì)氣化，把固體生物質(zhì)轉化為氣體燃料;二是氣體凈化，氣化出來(lái)的燃氣都帶有一定的雜質(zhì)，包括灰份、焦炭和焦油等，需經(jīng)過(guò)凈化系統把雜質(zhì)除去，以保證燃氣發(fā)電設備的正常運行;三是燃氣發(fā)電，利用燃氣輪機或燃氣內燃機進(jìn)行發(fā)電，有的工藝為了提高發(fā)電效率，發(fā)電過(guò)程可以增加余熱鍋爐和蒸汽輪機。

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(zhì)氣化發(fā)電技術(shù)是生物質(zhì)能利用中有別于其他可再生能源的獨特方式，具有三個(gè)方面特點(diǎn)：

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

1、是技術(shù)有充分的靈活性，由于生物質(zhì)氣化發(fā)電可以采用內燃機，也可以采用燃氣輪機，甚至結合余熱鍋爐和蒸汽發(fā)電系統，所以生物質(zhì)氣化發(fā)電可以根據規模的大小選用合適的發(fā)電設備，保證在任何規模下都有合理的發(fā)電效率。這一技術(shù)的靈活性能很好地滿(mǎn)足生物質(zhì)分散利用的特點(diǎn);

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、是具有較好的潔凈性，生物質(zhì)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(guò)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、是經(jīng)濟性，生物質(zhì)氣化發(fā)電技術(shù)的靈活性，可以保證該技術(shù)在小規模下有效好的經(jīng)濟性，同時(shí)燃氣發(fā)電過(guò)程簡(jiǎn)單，設備緊湊，也使生物質(zhì)氣化發(fā)電技術(shù)比其他可再生能源發(fā)電技術(shù)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,
