在使用沼气发电机组的时候，难免会遇到很多问题。在此小编为您总结了沼气发电机组九大实用问题，希望能给用户带来参考。

When using biogas generator sets, it is inevitable to encounter many problems. Here we summarize nine practical problems of biogas generator sets, hoping to give users a reference.

1.为什么要沼气发电？沼气发电机组有什么优点？

1. Why biogas power generation? What are the advantages of biogas generator sets?

沼气发电机组它利用工业、农业或城镇生活中的大量农业生产体系废弃物（例如：酒糟液、禽畜粪、城市垃圾和污水等）经厌氧发酵处理产生的沼气，驱动沼气发电机组发电，并可利用发电机组的余热用于沼气生产，使综合热效率达80％左右，大大高于一般30~40%的发电效率，用户的经济效益好。

The biogas generator unit uses the biogas produced by anaerobic fermentation treatment of a large number of agricultural production system wastes (such as distiller's grains, livestock manure, urban garbage and sewage) in industry, agriculture or urban life to drive the biogas generator unit to generate electricity, and can use the waste heat of the generator unit for biogas production, so that the comprehensive thermal efficiency can reach about 80%, which is much higher than the general power generation efficiency of 30-40%. The economic benefit of users is good.

2.沼气发电机组对沼气有什么要求？

2. What are the requirements for biogas generator set?

沼气中杂质含量如Si、HS等应控制在某范围内，沼气的温度为10~60℃，压力为0~5kpa，具体见沼气的气质要求，一般禽畜粪厌氧处理的沼气能满足发电的气质要求，污水处理沼气需要脱硫等处理，垃圾填埋沼气需要脱水等处理。

The content of impurities in the biogas, such as Si and HS, should be controlled within a certain range. The temperature of the biogas is 10~60 ℃, and the pressure is 0~5kpa. See the biogas quality requirements for details. Generally, the biogas for anaerobic treatment of livestock manure can meet the quality requirements for power generation. The biogas for sewage treatment needs desulfurization and other treatment, and the landfill biogas needs dehydration and other treatment.

3.发出来的电能否与电网6300V或10000V变压器相联？电网允许吗？

3. Can the power generated be connected with 6300V or 10000V transformers of the power grid? Is the grid allowed?

沼气发电机组的输出电压为400V，可以与6300V或10000V变压器低压端相联，若低压线路长，400V可以升压到6300V与供电局进线相连；若不上网送发电，为防止向网上倒送电加逆功率继电器保护，对电网运行没有影响。这种发电方式供电局不会责疑。

The output voltage of biogas generator set is 400V, which can be connected to the low-voltage terminal of 6300V or 10000V transformer. If the low-voltage line is long, 400V can be boosted to 6300V and connected to the incoming line of power supply bureau; If power generation is not transmitted to the network, reverse power relay protection is added to prevent reverse power transmission to the network, which has no impact on the grid operation. The power supply bureau will not be responsible for this power generation mode.

4.沼气浓度变化时，能否发电？

4. Can power be generated when biogas concentration changes?

发电机组照常可以运行，机组调整后可正常发电或降低发电量。

The generator set can operate normally, and can generate electricity normally or reduce the output after adjustment.

5.发电设备所需厂房条件怎么样？

5. What are the plant conditions required for power generation equipment?

两台沼气发电机组上网发电1000KW，厂房所需面积（含压缩机房、控制室、值班室）200平方米左右，厂房为普通厂房就可以。

Two biogas generator sets generate 1000KW of electricity on the grid. The required area of the plant (including compressor room, control room and duty room) is about 200 square meters, and the plant can be an ordinary plant.

6.沼气发电设备投资回收期多长？

6. How long is the investment recovery period of biogas power generation equipment?

包括发电机组在内的附属设备投资，若电费每千瓦时为0.6元，回收期为8个月，每千瓦时为0.5元，回收期为10个月左右，每千瓦时为0.4元，回收期为12个月。

For the investment in auxiliary equipment including generator set, if the electricity charge is 0.6 yuan per kilowatt hour, the payback period is 8 months, 0.5 yuan per kilowatt hour, about 10 months, 0.4 yuan per kilowatt hour, and 12 months.

7.沼气发电一方气发多少电？

7. How much electricity does biogas generate?

一度电运行成本（大修费用，财务费用，设备折旧）多少？一台设备一年运行多长时间？500KW发电机组，每月上网电量多少？一台设备运行多长时间大修？大修需多少时间？费用多少？

How much is the operating cost of one kilowatt hour power supply (overhaul cost, financial cost, equipment depreciation)? How long does a device run in a year? How much is the monthly on grid power of 500KW generator set? How long does an equipment run for overhaul? How long does the overhaul take? How much is it?

一方气发1.7KW.hr左右（沼气中甲烷浓度按照50%计算）。每千瓦时（含大修费，财务费用，折旧费用）运行费用为0.04—0.05元。

Yifang Gas Generator 1.7KW Hr (methane concentration in biogas is calculated as 50%). The operating cost per kilowatt hour (including overhaul cost, financial cost and depreciation cost) is 0.04-0.05 yuan.

8.设备运行人员需多少？

8. How many equipment operators are needed?

1~3台设备每班需要人员1~2人，维修人员1人。

Each shift of 1~3 sets of equipment requires 1~2 personnel and 1 maintenance personnel.

9.沼气发电机组使用寿命为多长时间？

9. How long is the service life of biogas generator set?

使用年限在20年以上，一年实际上网发电时间在7200小以上。

The service life is more than 20 years, and the actual power generation time in one year is more than 7200 hours.
