一、生物質氣發(fā)電機組發(fā)電方式：生物質氣化發(fā)電可通過三種途徑實現(xiàn)：生物質氣化產生燃氣作為燃料直接進入燃氣鍋爐生產蒸汽，再驅動蒸汽輪機發(fā)電；也可將凈化后的燃氣送給燃氣輪機燃燒發(fā)電；還可以將凈化后的燃氣送入內燃機直接發(fā)電。在發(fā)電和投資規(guī)模上，它們分別對應于大規(guī)模、中等規(guī)模和小規(guī)模的發(fā)電。

　　1、 The power generation method of biomass gas generator set: Biomass gasification power generation can be achieved through three ways: biomass gasification produces gas as fuel, which directly enters the gas boiler to produce steam, and then drives the steam turbine to generate electricity; The purified gas can also be sent to a gas turbine for combustion and power generation; The purified gas can also be sent to the internal combustion engine for direct power generation. In terms of power generation and investment scale, they correspond to large-scale, medium scale, and small-scale power generation, respectively.

　　在商業(yè)上最為成功的生物質氣化內燃發(fā)電技術，由于具有裝機容量小、布置靈活、投資少、結構緊湊、技術可靠、運行費用低廉、經濟效益顯著、操作維護簡單和對燃氣質量要求較低等特點，而得到廣泛的推廣與應用。

　　The most successful biomass gasification internal combustion power generation technology in business has been widely promoted and applied due to its small installed capacity, flexible layout, low investment, compact structure, reliable technology, low operating costs, significant economic benefits, simple operation and maintenance, and low requirements for gas quality.

　　二、生物質氣發(fā)電機組成成分：生物質氣化內燃發(fā)電系統(tǒng)主要由氣化爐、燃氣凈化系統(tǒng)和內燃發(fā)電機等組成：氣化爐是將生物質能由固態(tài)轉化為燃氣的裝置。生物質在氣化爐內通過控制空氣供應量，而進行不完全燃燒，實現(xiàn)低值生物質能由固體向氣態(tài)的轉化，生成包含氫氣（H2）、一氧化碳（CO）、甲烷（CH4）、多碳烴（CnHm）等可燃成分的燃氣，完成生物質的氣化過程。

　　2、 Composition of biomass gas generator: The biomass gasification internal combustion power generation system mainly consists of a gasifier, a gas purification system, and an internal combustion generator. The gasifier is a device that converts biomass energy from solid state to gas. Biomass undergoes incomplete combustion in a gasifier by controlling the air supply, achieving the conversion of low value biomass energy from solid to gas, generating combustible gases including hydrogen (H2), carbon monoxide (CO), methane (CH4), and hydrocarbons (CnHm), completing the gasification process of biomass.

　　氣化產生的燃氣出口溫度隨氣化爐型式的不同，在350℃～650℃之間，并且燃氣中含有未完全裂解的焦油及灰塵等雜質，為滿足內燃機長期可靠工作的要求，需要對燃氣進行冷卻和凈化處理，使燃氣溫度降到40℃以下、焦油灰塵含量控制在50mg/Nm3以內，燃氣經過凈化后，再進入內燃機發(fā)電。

　　The outlet temperature of the gas generated by gasification varies depending on the type of gasifier, ranging from 350 ℃ to 650 ℃. The gas also contains impurities such as incompletely cracked tar and dust. In order to meet the long-term reliable operation requirements of internal combustion engines, it is necessary to cool and purify the gas to reduce the temperature to below 40 ℃ and control the tar and dust content within 50mg/Nm3. After purification, the gas enters the internal combustion engine for power generation.

　　在內燃機內，燃氣混合空氣燃燒做功，驅動主軸高速轉動，主軸再帶動發(fā)電機進行發(fā)電。

　　In an internal combustion engine, the mixture of gas and air burns to do work, driving the main shaft to rotate at high speed, which in turn drives the generator to generate electricity.

　　生物質氣化內燃發(fā)電就是通過以上過程，將各種廢棄物化廢為寶，轉化為優(yōu)質電能，解決廢棄物的污染和能源的合理利用問題。

　　Biomass gasification internal combustion power generation is the process of turning various waste materials into treasure, converting them into high-quality electricity, and solving the problems of waste pollution and rational energy utilization.
