　　4關(guān)于《中大功率沼氣發(fā)電機(jī)組》《大功率沼氣發(fā)電機(jī)組》(GB/T 29488-2013)是由中國(guó)石油集團(tuán)濟(jì)柴動(dòng)力總廠負(fù)責(zé)起草，國(guó)家質(zhì)量監(jiān)督檢驗(yàn)檢疫總局和標(biāo)準(zhǔn)化管理委員會(huì)發(fā)布實(shí)施的，適用于“額定頻率為50Hz或60Hz，功率不小于250kW，以沼氣（甲烷含量不低于30%）為主要燃料的往復(fù)式內(nèi)燃機(jī)驅(qū)動(dòng)的交流工頻發(fā)電機(jī)組”。該標(biāo)準(zhǔn)規(guī)定“機(jī)組在額定工況時(shí)排出的NOx污染物排放限值為3.48g/kWh”，相近于《車用點(diǎn)燃式發(fā)動(dòng)機(jī)及裝用點(diǎn)燃式發(fā)動(dòng)機(jī)汽車排放污染物排放限值及測(cè)量方法》，同前述相同，SO2的排放與氣源有關(guān)，也無(wú)從規(guī)定。

　　Regarding the "Medium and High Power Biogas Generator Sets" and "High Power Biogas Generator Sets" (GB/T 29488-2013), they were drafted by China Petroleum Group Jichai Power Plant and implemented by the General Administration of Quality Supervision, Inspection and Quarantine and the Standardization Management Committee. They are applicable to "AC power frequency generator sets driven by reciprocating internal combustion engines with rated frequency of 50Hz or 60Hz, power not less than 250kW, and mainly fueled by biogas (methane content not less than 30%)". This standard stipulates that the emission limit of NOx pollutants emitted by the unit under rated operating conditions is 3.48g/kWh, which is similar to the "Emission Limits and Measurement Methods for Vehicles with Spark Ignition Engines and Vehicles Equipped with Spark Ignition Engines". Similarly, the emission of SO2 is related to the gas source and cannot be regulated.
