U can be high, medium and low voltage output, reduce the initial investment and operating costs

300燃氣發電機組可以定制10500V、6300V、400V高、中、低壓輸出，滿足用戶各種不同需求，可避免購買變壓器的初始投資，減少銅損，降低運行成本；既可并網又可直接帶負荷使用，大大提高了機組的經濟效益。

The 300 gas-fired generator set can be customized with 10500v, 6300v, 400V high, medium and low voltage output to meet various needs of users, avoid initial investment in purchasing transformer, reduce copper loss and reduce operation cost; it can be connected to the grid and directly used with load, greatly improving the economic benefits of the unit.

u大缸徑、長行程保證機組輸出功率持續穩定

U large cylinder diameter and long stroke ensure the continuous and stable output power of the unit

300系列燃氣發電機組的原動機是缸徑為300mm的300型柴油機改型而來的，具有缸徑大、行程長、轉速低、功率儲備大的特點，比高速機組更適合燃氣壓力低的特點，是燃氣發電機組的原動機，機組輸出功率持續穩定。

The prime mover of 300 series gas generator set is a modified 300 type diesel engine with a cylinder diameter of 300 mm. It has the characteristics of large cylinder diameter, long stroke, low speed and large power reserve. It is more suitable for the characteristics of low gas pressure than high-speed unit. It is the best prime mover of gas generator set, and the output power of the unit is continuously stable.

u低轉速保證機組使用壽命

U low speed to ensure the service life of the unit

機組轉速以500r/min、600r/min為主，低轉速降低發動機零部件摩擦副的磨損，延長機件的使用壽命，減少備件的儲備，提高用戶的經濟效益。

The rotation speed of the unit is mainly 500r / min and 600r / min. low rotation speed can reduce the wear of friction pairs of engine parts, prolong the service life of parts, reduce the reserve of spare parts, and improve the economic benefits of users.

u非增壓機組自然吸氣，對燃氣適用范圍廣，故障率低

U non supercharged unit is naturally aspirated, which has wide application range for gas and low failure rate

300發動機單缸排放量大，可使低壓的燃氣和空氣被原動機自然吸入（氣源的壓力只需要大于2kPa即可），使燃氣機組的使用范圍更廣，氣源低壓輸送更安全。自吸式進氣，氣體混合后直接進入燃燒室，不需要渦輪增壓器、中冷器等進氣環節，部件少，自然減少了故障率。

The single cylinder emission of 300 engine is large, so that the low-pressure gas and air can be naturally inhaled by the prime mover (the pressure of the gas source only needs to be greater than 2KPa), so that the gas unit can be used more widely and the low-pressure transmission of the gas source is safer. Self suction intake, gas mixture directly into the combustion chamber, do not need turbocharger, intercooler and other intake links, fewer components, naturally reduce the failure rate.

u直列正置式結構簡化發動機布局，結構簡潔、維護方便

The structure is simple and easy to maintain

300系列燃氣發動機為直列機，維護操作空間大；特別是曲軸正置式結構，不管是機組大修還是軸系維護，只要在現場就可解決，大大節省維護時間和維護成本。而國內V型高速機曲軸倒掛式結構，若沒有翻轉工裝的輔助，無法現場大修，必須返回制造廠進行維護。

The 300 series gas engine is an in-line engine, which has a large space for maintenance and operation. In particular, the crankshaft upright structure can be solved on site, which can greatly save maintenance time and cost. The domestic V-type high-speed machine crankshaft upside down structure, if there is no professional turnover tooling assistance, can not be overhauled on site, must return to the manufacturer for maintenance.

u多道防線確保燃氣安全利用

U multiple defense lines to ensure safe and efficient use of gas

先進的空燃比控制技術保證發動機以比較理想的混合氣比例進氣；發動機進氣管設置防爆閥，一旦回火自動泄壓；安裝在管道上的阻火器對火焰有淬熄作用能阻止火焰的傳播蔓延；電磁閥會迅速切斷燃氣氣源，確保機組安全。

Advanced air-fuel ratio control technology ensures that the engine is fed with ideal mixture ratio; explosion proof valve is set in the intake pipe of the engine to automatically relieve pressure once tempering; flame arrester installed on the pipe has quenching effect on the flame, which can prevent the spread of the flame; solenoid valve will quickly cut off the gas source to ensure the safety of the unit.

u余熱回收利用、實現燃氣熱電聯產綜合利用

U waste heat recovery and utilization to realize comprehensive utilization of gas cogeneration

機組的廢氣直接余熱鍋爐，產生熱水或蒸汽，機組循環冷卻產生熱水，均可提供取暖洗浴及其他用熱，通過綜合利用實現燃氣綜合熱效率達到70%以上，提高了經濟效益。

The waste gas direct waste heat boiler of the unit produces hot water or steam, and the circulating cooling of the unit produces hot water, which can provide heating, bathing and other heat. Through comprehensive utilization, the comprehensive thermal efficiency of gas can reach more than 70%, and the economic benefit is improved.

u計算機監控管理系統，可實現在線監測與自動控制

U computer monitoring and management system can realize online monitoring and automatic control

通過計算機監控系統，實現運行數據在線監測實時控制，并實現自動合閘并網、故障診斷、空燃比自動調節等功能，可實現遠程管理。

Through the computer monitoring system, the online monitoring and real-time control of operation data are realized, and the functions of automatic switch on and grid connection, fault diagnosis and automatic adjustment of air-fuel ratio are realized, which can realize remote management.
