沼气发电技术本身提供了清洁能源，不仅解决了沼气项目中的环境问题，消耗了大量废物，保护了环境，减少了温室气体排放，而且还将废物转化为财富，产生了大量的热能和电能，符合能源回收的环保理念，也带来了巨大的经济效益。

The biogas power generation technology itself provides clean energy, not only solving environmental problems in biogas projects, consuming a large amount of waste, protecting the environment, reducing greenhouse gas emissions, but also transforming waste into wealth, generating a large amount of heat and electricity, in line with the environmental protection concept of energy recovery, and bringing huge economic benefits.

使用沼气发电机组时应注意以下事项：

When using biogas generator sets, the following precautions should be taken:

1.必须做好甲烷脱硫和脱水工作，及时使用和更换高效工业脱硫剂。目前，市场上很好的氧化铁脱硫剂的硫容量约为15%。养殖场沼气处理脱硫剂的使用寿命约为1500小时，脱硫剂到期必须更换。

1. Methane desulfurization and dehydration work must be done well, and efficient industrial desulfurizers must be used and replaced in a timely manner. At present, the sulfur capacity of excellent iron oxide desulfurizers on the market is about 15%. The service life of the desulfurizer for biogas treatment in aquaculture farms is about 1500 hours, and the desulfurizer must be replaced when it expires.

2.确保使用沼气发动机专用油。专用油比普通油粘度高，能吸收沼气中的硫，能有效防止涡轮增压器轴的腐蚀。

2. Ensure the use of biogas engine specific oil. Specialized oil has a higher viscosity than regular oil and can absorb sulfur from biogas, effectively preventing corrosion of the turbocharger shaft.

3.换油周期不得超过400小时。即使未及时更换专用机油，机油的粘度也会降低并变脏，这将导致涡轮增压器的机油流动不良，加速高速时的磨损。

3. The oil change interval should not exceed 400 hours. Even if the specialized oil is not replaced in a timely manner, the viscosity of the oil will decrease and become dirty, which will lead to poor oil flow in the turbocharger and accelerated wear at high speeds.

4.每次启动后，不要立即带负荷打开沼气发生器。因为机油循环到涡轮增压器需要一些时间。当机油尚未到达增压器油管时，突然加载还会导致增压器轴、叶片等因缺乏润滑而磨损。

4. After each startup, do not immediately turn on the biogas generator with load. Because it takes some time for the oil to circulate to the turbocharger. When the oil has not yet reached the turbocharger oil pipe, sudden loading can also cause wear on the turbocharger shaft, blades, etc. due to lack of lubrication.

目前，沼气发电机组的增压器主要有几种类型，包括Hollset和Honeywell。但目前增压器主要适用于车辆，沼气发生器属于同一生产线的生产，但由于沼气本身含有一定量的硫化氢，沼气机组一般采用增压器前的预混合方式，因此在长期未完成脱硫的环境中，机组很容易聚集在增压器的压缩机端叶轮上。

At present, there are several types of boosters for biogas generators, including Hollset and Honeywell. However, currently the supercharger is mainly suitable for vehicles, and the biogas generator belongs to the same production line. However, due to the presence of a certain amount of hydrogen sulfide in the biogas itself, the biogas unit generally adopts a pre mixing method before the supercharger. Therefore, in an environment where desulfurization has not been completed for a long time, the unit is prone to accumulate on the compressor end impeller of the supercharger.

在正常工作条件下，增压器需要以每分钟数万到数十万转的速度增压，这需要非常严格的动态平衡。一旦元素硫积聚在风扇叶片上，它将不可避免地损坏增压器的动态平衡。很早的症状是大量烟雾从排气端排出。此时，需要立即修复。您可以找到安第斯新能源为增压器提供维护服务。在严重情况下，它会直接卡住，无法工作。通常，该装置的制造商建议用户直接更换增压器。然而，更换一段时间后会出现相同的症状，这大大缩短了机组的在线运行时间。

Under normal working conditions, the turbocharger needs to boost at a speed of tens to hundreds of thousands of revolutions per minute, which requires very strict dynamic balancing. Once elemental sulfur accumulates on the fan blades, it will inevitably damage the dynamic balance of the turbocharger. The early symptom is a large amount of smoke being expelled from the exhaust end. At this point, immediate repair is required. You can find Andean New Energy to provide maintenance services for the turbocharger. In severe cases, it will directly jam and fail to function. Usually, the manufacturer of the device recommends that the user directly replace the turbocharger. However, after a period of replacement, the same symptoms will appear, which greatly shortens the online operation time of the unit.
