單燃料沼氣發電機組工作原理及優點：將“空氣沼氣”的混合物在氣缸內壓縮，用火花塞使其燃燒，通過活塞的往復運動得到動力，然后連接發電機發電。

　　Working principle and advantages of single fuel biogas generator set: The mixture of "air biogas" is compressed in the cylinder, burned with spark plugs, and powered by the reciprocating motion of the piston, and then connected to the generator to generate electricity.

　　不需要輔助燃料油及其供給設備。

　　No need for auxiliary fuel oil and its supply equipment.

　　燃料為一個系統，在控制方面比可燒兩種燃料的發電機組簡單。

　　Fuel is a system that is simpler to control than a generator set that can burn two different fuels.

　　發電機組價格較低。

　　The price of generator sets is relatively low.

　　雙燃料沼氣-柴油發電機組工作原理及優點：將“空氣燃燒氣體”的混合物在氣缸內壓縮，用點火燃料使其燃燒，通過活塞的往復運動得到動力，然后連接發電機發電。

　　Working principle and advantages of dual fuel biogas diesel generator set: The mixture of "air combustion gas" is compressed in the cylinder, ignited with fuel, and powered by the reciprocating motion of the piston, and then connected to the generator to generate electricity.

　　用液體燃料或氣體燃料都可工作。

　　It can work with liquid fuel or gas fuel.

　　對沼氣的產量和甲烷濃度的變化能夠適應。

　　Can adapt to changes in biogas production and methane concentration.

　　如由用氣體燃料轉為用柴油燃料在停止工作，發電機組內不殘留未燃燒的氣體，因為耐腐蝕性好。

　　If gas fuel is switched to diesel fuel during shutdown, there will be no unburned gas left in the generator set due to its good corrosion resistance.

　　兩種沼氣發電機組缺點:工作受到供給的沼氣的數量和質量的影響

　　Disadvantages of two types of biogas generators: their operation is affected by the quantity and quality of biogas supplied

　　用氣體燃料工作時也需要液體輔助燃料。

　　When working with gas fuel, liquid auxiliary fuel is also required.

　　需要液體燃料供給設備。

　　Liquid fuel supply equipment is required.

　　控制機構稍復雜。

　　The control mechanism is slightly more complex.

　　價格較單燃料式發電機組稍高。

　　The price is slightly higher than that of single fuel generator sets.

　　阻火器在沼氣發電機組的安裝

　　Installation of flame arrester in biogas generator set

　　沼氣發電是集環保和節能于一體的能源綜合利用新技術，沼氣發電機組要安裝管道阻火器，防止發動起回火給沼氣儲運管道帶來危險。

　　Biogas power generation is a new technology for comprehensive energy utilization that integrates environmental protection and energy conservation. Biogas generator units should be equipped with pipeline flame arresters to prevent the risk of backfire during operation, which could pose a danger to the biogas storage and transportation pipelines.
