1、 Requirements for the use of gas in gas generator sets

燃?xì)獍l(fā)電機(jī)組的燃料以沼氣為主，也可以使用油田伴生氣、液化石油氣、天然氣等可燃性氣體。所用的氣體應(yīng)通過(guò)干燥脫水，達(dá)到無(wú)游離水、原油和輕質(zhì)油，其低熱值不應(yīng)低于31.4mj/m3,總硫含量不大于480mg/m3,硫化氫含量不大于20mg/m3.此外天然氣輸送壓力在0.08－0.30MAP范圍內(nèi)。

The fuel of gas generator set is mainly biogas, and it can also use the associated gas of oil field, liquefied petroleum gas, natural gas and other combustible gases. The gas used shall be dried and dehydrated to be free of free water, crude oil and light oil. Its low calorific value shall not be less than 31.4mj/m3, total sulfur content shall not be more than 480mg/m3, and hydrogen sulfide content shall not be more than 20mg/m3. In addition, the transmission pressure of natural gas shall be within 0.08-0.30MAP.

二．燃?xì)獍l(fā)電機(jī)組使用冷卻液

2、 Coolant for gas generator set

用于冷卻系統(tǒng)的直接冷卻發(fā)動(dòng)機(jī)的冷卻液通常使用清潔的淡水，雨水或經(jīng)澄清的河水為宜。當(dāng)燃?xì)獍l(fā)電機(jī)組在低于0度的環(huán)境條件使用時(shí)，應(yīng)嚴(yán)防冷卻液凍結(jié)，致使零件凍裂。可根據(jù)溫度來(lái)配用適當(dāng)凝點(diǎn)的防凍液或在起動(dòng)前加注熱水，但停車后應(yīng)立即放水。

The coolant of direct cooling engine used for cooling system usually uses clean fresh water, rainwater or clarified river water. When the gas generator set is used under the environmental conditions lower than 0 ℃, the cooling liquid shall be strictly prevented from freezing, which may cause the parts to freeze and crack. Antifreeze with proper freezing point can be prepared according to temperature or hot water can be added before starting, but water shall be drained immediately after shutdown.

三．燃?xì)獍l(fā)電機(jī)組所用的機(jī)油

3、 Oil for gas generator set

燃?xì)獍l(fā)電機(jī)組的運(yùn)動(dòng)件并對(duì)這些運(yùn)動(dòng)件起到冷卻散熱、帶走雜質(zhì)和防止銹的作用。其品質(zhì)的好壞除對(duì)燃?xì)獍l(fā)電機(jī)組的性能和使用壽命有影

The moving parts of gas generator set can cool and dissipate heat, take away impurities and prevent rust. Its quality will not only affect the performance and service life of the gas generator set

響外，對(duì)機(jī)油的使用期限有一定的影響。為此，應(yīng)根據(jù)燃?xì)獍l(fā)電機(jī)組的使用環(huán)境溫度來(lái)選適當(dāng)?shù)臋C(jī)油。

It has certain influence on the service life of the engine oil. To this end, the appropriate engine oil should be selected according to the operating ambient temperature of the gas generator set.
