The 300 series gas generator unit has the advantages of large cylinder diameter, long stroke and large displacement. For biomass gas with low calorific value, it can ensure that the output power of the unit remains constant.

系列机组采用内混式进气系统及空燃比自动控制系统，彻底避免了高氢燃气回火放炮问题。阻绝回火，确保燃气输送。

The series units adopt the internal mixing air intake system and the air fuel ratio automatic control system, which completely avoids the problem of high hydrogen gas backfire blasting. Prevent flashback and ensure the safety of gas transmission.

自然吸气，确保燃气输送，气源的压力只需大于 2kpa即可，使燃气机组的适用范围更广，对燃气中焦油的适用性强，气 源低压输送更。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。

Natural suction ensures the safety of gas transmission. The pressure of the gas source only needs to be greater than 2 kpa, which makes the gas unit more applicable to the tar in the gas, and the low pressure transmission of the gas source safer. Self-priming air intake, the gas directly enters the combustion chamber after mixing, without the need for turbocharger, intercooler and other air intake links, fewer components, naturally reducing the failure rate.

系列燃气机组点火系统采用美国或德国进口等点火系统，保证点火受控，确保获得高的点火能量和精确的点火时间，使做 功更彻底，能量更大，爆发力更强。

The ignition system of the series of gas units adopts ignition systems imported from the United States or Germany to ensure controlled ignition, high ignition energy and accurate ignition time, so as to make the work more complete, more energy and more explosive.

可拆卸进气阀箱，不需拆卸缸盖即可方便维护进气阀，方便清理生物质气中的焦油。

The detachable inlet valve box can facilitate the maintenance of the inlet valve without removing the cylinder head, and facilitate the cleaning of tar in the biomass gas.

低转速确保机组使用寿命，保证年运行 8000h, 大修周期 60000h。

The low speed ensures the service life of the unit, ensures the annual operation of 8000h, and the overhaul period of 60000 h.

机组可以手动、自动并机并网功能，亦可孤岛运行，可实现远程监控及操作等功能。

The unit can be connected to the grid manually and automatically, and can also operate in isolation, and can realize remote monitoring and operation.
