一、技术原理

1、 Technical principles

生物质气发电机组的核心在于生物质气的产生与发电过程的完美结合。生物质气的制备主要通过气化和发酵两种技术路径。气化技术是在高温缺氧或微氧条件下，使生物质发生热化学反应，分解成一氧化碳、氢气、甲烷等可燃气体，这些气体组成的混合气体被称为生物质合成气。以木屑为例，经过气化炉的高温处理，能够产出热值可观的合成气。发酵技术则主要用于处理富含有机物的生物质，如畜禽粪便、污水污泥等，在厌氧环境下，微生物将有机物分解，产生以甲烷为主要成分的沼气。​

The core of biomass gas power generation unit lies in the perfect combination of biomass gas generation and power generation process. The preparation of biomass gas mainly involves two technical pathways: gasification and fermentation. Gasification technology is a thermal chemical reaction that occurs under high temperature, oxygen deficient or micro oxygen conditions to decompose biomass into combustible gases such as carbon monoxide, hydrogen, methane, etc. The mixed gas composed of these gases is called biomass synthesis gas. Taking sawdust as an example, after high-temperature treatment in a gasifier, it can produce synthetic gas with considerable calorific value. Fermentation technology is mainly used to treat biomass rich in organic matter, such as livestock manure, sewage sludge, etc. In anaerobic environments, microorganisms decompose organic matter to produce biogas mainly composed of methane. ​

产生的生物质气进入发电机组后，与传统燃气发电机组的工作原理相似。在燃气内燃机或燃气轮机中，生物质气与空气混合后被点燃，燃烧产生的高温高压气体推动活塞或涡轮转动，进而带动发电机发电。部分先进的生物质气发电机组还配备了余热回收系统，将燃烧过程中产生的余热用于预热生物质原料、加热水或驱动吸收式制冷机，大大提高了能源的综合利用效率，使整个系统的能源利用率可提升至 80% 以上。

After entering the power generation unit, the generated biomass gas works similarly to the working principle of traditional gas-fired power generation units. In gas internal combustion engines or gas turbines, biomass gas is mixed with air and ignited. The high-temperature and high-pressure gas produced by combustion drives the piston or turbine to rotate, thereby driving the generator to generate electricity. Some advanced biomass gas power generation units are also equipped with waste heat recovery systems, which use the waste heat generated during the combustion process to preheat biomass raw materials, heat water, or drive absorption refrigeration machines, greatly improving the comprehensive utilization efficiency of energy and increasing the energy utilization rate of the entire system to over 80%.

二、有发展什么优势

2、 What are the advantages of development

1、环保效益显著​

1. Significant environmental benefits

生物质气发电机组从源头上减少了废弃物的堆积和污染排放。以秸秆为例，每利用 1 吨秸秆发电，可减少约 1.2 吨二氧化碳当量的温室气体排放，相当于植树造林 66 平方米。同时，避免了秸秆焚烧产生的大量烟尘、二氧化硫等污染物，改善了空气质量。处理有机垃圾和废水时，也能有效降低水体富营养化风险，保护生态环境。​

Biomass gas power generation units reduce the accumulation of waste and pollution emissions from the source. Taking straw as an example, for every ton of straw used for power generation, about 1.2 tons of carbon dioxide equivalent greenhouse gas emissions can be reduced, equivalent to planting 66 square meters of trees. At the same time, it avoids the large amount of pollutants such as smoke and sulfur dioxide generated by straw burning, and improves air quality. When dealing with organic waste and wastewater, it can also effectively reduce the risk of eutrophication in water bodies and protect the ecological environment. ​

2、能源供应多元化​

2. Diversified energy supply

生物质气作为一种可再生能源，丰富了能源供应体系。它不受地域、季节限制，在不同地区都能找到合适的生物质原料进行发电。在一些偏远地区，电网覆盖不足，生物质气发电机组可作为独立的供电系统，保障居民和企业用电，提高能源供应的稳定性和可靠性。​

Biomass gas, as a renewable energy source, enriches the energy supply system. It is not limited by geography or season, and suitable biomass materials can be found for power generation in different regions. In some remote areas where the power grid coverage is insufficient, biomass gas generators can serve as an independent power supply system to ensure the electricity supply for residents and businesses, and improve the stability and reliability of energy supply. ​

3、经济效益可观​

3. Significant economic benefits

生物质气发电项目不仅能产生电力收益，还能通过销售沼渣、沼液等副产品增加收入。同时，企业利用自身产生的生物质资源发电，可降低用电成本，减少对外部能源的依赖。此外，国家和地方政府对生物质能产业出台了一系列补贴政策，进一步提高了项目的盈利能力，吸引了更多社会资本投入，推动产业快速发展。

Biomass gas power generation projects can not only generate electricity revenue, but also increase income through the sale of by-products such as sludge and slurry. At the same time, enterprises can use their own biomass resources to generate electricity, which can reduce electricity costs and decrease dependence on external energy sources. In addition, the national and local governments have introduced a series of subsidy policies for the biomass energy industry, further improving the profitability of projects, attracting more social capital investment, and promoting the rapid development of the industry.
