① 不需要輔助燃料油及其供給設(shè)備

① Auxiliary fuel oil and its supply equipment are not required

② 燃料為一個(gè)系統(tǒng)，在控制方面比可燒兩種燃料的發(fā)電機(jī)組簡單

② The fuel is a system, which is simpler in control than a generator set that can burn two fuels

③ 發(fā)電機(jī)組價(jià)格較低

③ The price of generator set is low

雙燃料沼氣發(fā)電機(jī)組工作原理及優(yōu)點(diǎn)：將“空氣燃燒氣體”的混合物在氣缸內(nèi)壓縮，用點(diǎn)火燃料使其燃燒，通過活塞的往復(fù)運(yùn)動(dòng)得到動(dòng)力，然后連接發(fā)電機(jī)發(fā)電。

Working principle and advantages of dual fuel biogas generator set: compress the mixture of "air combustion gas" in the cylinder, burn it with ignition fuel, obtain power through the reciprocating motion of the piston, and then connect the generator to generate electricity.

① 用液體燃料或氣體燃料都可工作

① It can work with liquid fuel or gas fuel

② 對沼氣的產(chǎn)量和甲烷濃度的變化能夠適應(yīng)

② It can adapt to the changes of biogas output and methane concentration

③ 如由用氣體燃料轉(zhuǎn)為用柴油燃料在停止工作，發(fā)電機(jī)組內(nèi)不殘留未燃燒的氣體，因?yàn)轲I耐腐蝕性好

③ In case of switching from gas fuel to diesel fuel and stopping working, there will be no unburned gas left in the generator set because of its good corrosion resistance

兩種沼氣發(fā)電機(jī)組缺點(diǎn):工作受到供給的沼氣的數(shù)量和質(zhì)量的影響

Disadvantages of two kinds of biogas generating units: the work is affected by the quantity and quality of biogas supplied

① 用氣體燃料工作時(shí)也需要液體輔助燃料

① Liquid auxiliary fuel is also required when working with gaseous fuel

② 需要液體燃料供給設(shè)備

② Liquid fuel supply equipment is required

③ 控制機(jī)構(gòu)稍復(fù)雜

③ The control mechanism is slightly complex

④ 借個(gè)較單燃料式發(fā)電機(jī)組稍高

④ Borrow a slightly higher than the single fuel generator set
