To address the controversial issue of implementing emission standards for biogas generator sets, we first need to clarify the working principle of biogas generator sets? Due to the social and economic benefits of biogas power generation projects, the use of biogas power generation units for grid connection generally adopts reciprocating gas internal combustion unit power generation technology with smaller single unit power. Through the combustion of biogas in the cylinder, the piston movement is driven to generate power, which then drives the generator to operate and generate electricity.

燃?xì)鈨?nèi)燃機(jī)組發(fā)電技術(shù)具有如下特點(diǎn)：

The gas internal combustion unit power generation technology has the following characteristics:

①單位千瓦建站投資少，2500~3500元/kW；投資回報(bào)率高：45%~80%；運(yùn)行成本低：0.1~0.12元/kWh。

① Low investment per kilowatt for station construction, ranging from 2500 to 3500 yuan/kW; High investment return rate: 45%~80%; Low operating cost: 0.1-0.12 yuan/kWh.

②燃?xì)鈨?nèi)燃機(jī)機(jī)組配套設(shè)備簡(jiǎn)單，電站可移動(dòng)性強(qiáng)。

② The supporting equipment of the gas internal combustion engine unit is simple, and the power station has strong mobility.

③機(jī)組單機(jī)功率范圍：4kW~2000kW，可以單臺(tái)工作，也可多臺(tái)并網(wǎng)，建站靈活。

③ The single unit power range of the unit is 4kW~2000kW, which can operate as a single unit or connect multiple units to the grid, making station construction flexible.

④電站自耗電少，不超過發(fā)電量的2%。

④ The self consumption of the power station is low, not exceeding 2% of the power generation.

⑤燃?xì)鈨?nèi)燃及采用熱電冷聯(lián)供，機(jī)組熱效率可達(dá)80%。

⑤ Gas internal combustion and the use of combined heat, power, and cooling can achieve a thermal efficiency of up to 80% for the unit.

⑥對(duì)沼氣氣源條件要求較低。

⑥ Low requirements for biogas source conditions.
