生物质能源是人类直接的能源，在18世纪大规模地利用煤燃料以前，人类主要依靠木材作燃料。生物质所蕴藏的能量是相当惊人的，根据生物学家估算，地球上每年生长的生物质能总量约1400-1800亿吨（干重），相当于目前世界总能耗的10倍。我国的生物质能也极为丰富，例如现在每年的秸秆量约8亿吨左右，相当于5亿吨左右标煤。柴薪和林业废弃物数量也很大，林业废弃物（不包括炭薪林），每年约达3700m3，相当于2000万吨标煤。
Biomass energy is a direct source of energy for humans. Before large-scale utilization of coal fuel in the 18th century, humans mainly relied on wood as fuel. The energy stored in biomass is quite amazing. According to biologists' estimates, the total amount of biomass energy grown on the Earth each year is about 1400-180 billion tons (dry weight), equivalent to 10 times the current world's total energy consumption. China is also extremely rich in biomass energy, for example, the annual amount of straw is about 800 million tons, equivalent to about 500 million tons of standard coal. The amount of firewood and forestry waste is also large, with forestry waste (excluding charcoal forest) reaching approximately 3700m3 per year, equivalent to 20 million tons of standard coal.
生物质燃烧是传统的利用方式，但是热效率低下，而且劳动强度大，污染严重。通过生物质能转换技术可以高效地利用生物质能源，生产各种清洁燃料，代替煤炭、石油和天然气等燃料；还可以用来生产电力，减少对矿物能源的依赖，保护国家能源资源，减轻能源消费给环境造成的污染。
Biomass combustion is a traditional utilization method, but its thermal efficiency is low, labor intensity is high, and pollution is serious. Biomass energy conversion technology can efficiently utilize biomass energy to produce various clean fuels, replacing fuels such as coal, oil, and natural gas; It can also be used to produce electricity, reduce dependence on mineral energy, protect national energy resources, and reduce environmental pollution caused by energy consumption.

生物质气化是指在无氧或缺氧的高温环境下，使生物质固体原料发生热分解或不完全燃烧而转化为生物质燃气的热化学转化过程。在农村活上，生物质燃气可以用于做饭或者冬季供暖；在工业上，生物质燃气可以直接驱动工业锅炉生产蒸汽。净化后的生物质燃气还可以带动发电机组发电，为缺乏电力的地区供电。
Biomass gasification refers to a thermochemical conversion process that converts biomass solid feedstock into biomass gas through thermal decomposition or incomplete combustion in a high temperature environment without oxygen or oxygen deficiency. In rural areas, biomass gas can be used for cooking or winter heating; In industry, biomass gas can directly drive industrial boilers to produce steam. Purified biomass gas can also drive power generation units to generate electricity for areas lacking electricity.

生物质气化技术改变了传统直接燃烧生物质来获取能量的方式，通过气化技术，将生物质转变为清洁的可燃气体，大大提高生物质能源的使用范围。生物质气化技术有以下独特优势：
Biomass gasification technology has changed the traditional way of directly burning biomass to obtain energy. Through gasification technology, biomass is transformed into clean combustible gas, greatly improving the range of use of biomass energy. Biomass gasification technology has the following unique advantages:
大量性和普遍性：生物质是一种到处都有的，普遍而廉价的能源，取材容易，生产过程简单。
Massiveness and universality: Biomass is a ubiquitous and inexpensive energy source that is easy to obtain and simple to produce.
可再生性：生物质能是一种理想的可再生能源。只要太阳辐射能存在，绿色植物的光合作用就不会停止，生物质能就永远不会枯竭。
Renewableity: Biomass energy is an ideal renewable energy source. As long as solar radiation energy exists, the photosynthesis of green plants will not stop, and biomass energy will never be exhausted.
环保性：用生物质能作为能源，可以减少对环境的污染。生物质原料主要是农林废弃物，堆放腐烂会污染环境，滋生细菌，蚊虫，产生硫化氢和甲烷等有害有臭味的气体，既占用土地资源又污染环境。
Environmental friendliness: Using biomass energy as energy can reduce environmental pollution. Biomass raw materials are mainly agricultural and forestry wastes, which can pollute the environment by piling up and rotting, breeding bacteria, mosquitoes, and producing harmful and odorous gases such as hydrogen sulfide and methane, both occupying land resources and polluting the environment.
清洁性：用生物质发电，利用的是植物体内的有机物质，系统排放的二氧化碳会被下一季的植物生长所吸收，所以并没有增加大气中二氧化碳的含量，可以实现二氧化碳的“零排放”。
Cleanliness: Using biomass for power generation utilizes organic substances in plants. The carbon dioxide emitted by the system will be absorbed by the growth of plants in the next season, so it does not increase the content of carbon dioxide in the atmosphere, and can achieve "zero emissions" of carbon dioxide.
