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

300燃气发电机组可以定制10500V、6300V、400V高、中、低压输出，满足用户各种不同需求，可避免购买变压器的初始投资，减少铜损，降低运行成本；既可并网又可直接带负荷使用，大大提高了机组的经济效益。

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大缸径、长行程保证机组输出功率持续稳定

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

300系列燃气发电机组的原动机是缸径为300mm的300型柴油机改型而来的，具有缸径大、行程长、转速低、功率储备大的特点，比高速机组更适合燃气压力低的特点，是燃气发电机组的原动机，机组输出功率持续稳定。

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低转速保证机组使用寿命

U low speed to ensure the service life of the unit

机组转速以500r/min、600r/min为主，低转速降低发动机零部件摩擦副的磨损，延长机件的使用寿命，减少备件的储备，提高用户的经济效益。

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非增压机组自然吸气，对燃气适用范围广，故障率低

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

300发动机单缸排放量大，可使低压的燃气和空气被原动机自然吸入（气源的压力只需要大于2kPa即可），使燃气机组的使用范围更广，气源低压输送更安全。自吸式进气，气体混合后直接进入燃烧室，不需要涡轮增压器、中冷器等进气环节，部件少，自然减少了故障率。

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直列正置式结构简化发动机布局，结构简洁、维护方便

The structure is simple and easy to maintain

300系列燃气发动机为直列机，维护操作空间大；特别是曲轴正置式结构，不管是机组大修还是轴系维护，只要在现场就可解决，大大节省维护时间和维护成本。而国内V型高速机曲轴倒挂式结构，若没有翻转工装的辅助，无法现场大修，必须返回制造厂进行维护。

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多道防线确保燃气安全利用

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

先进的空燃比控制技术保证发动机以比较理想的混合气比例进气；发动机进气管设置防爆阀，一旦回火自动泄压；安装在管道上的阻火器对火焰有淬熄作用能阻止火焰的传播蔓延；电磁阀会迅速切断燃气气源，确保机组安全。

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余热回收利用、实现燃气热电联产综合利用

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

机组的废气直接余热锅炉，产生热水或蒸汽，机组循环冷却产生热水，均可提供取暖洗浴及其他用热，通过综合利用实现燃气综合热效率达到70%以上，提高了经济效益。

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计算机监控管理系统，可实现在线监测与自动控制

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

通过计算机监控系统，实现运行数据在线监测实时控制，并实现自动合闸并网、故障诊断、空燃比自动调节等功能，可实现远程管理。

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.
