在使用沼氣發電機組的時候，難免會遇到很多問題。在此小編為您總結了沼氣發電機組九大實用問題，希望能給用戶帶來參考。

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.為什么要沼氣發電？沼氣發電機組有什么優點？

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

沼氣發電機組它利用工業、農業或城鎮生活中的大量農業生產體系廢棄物（例如：酒糟液、禽畜糞、城市垃圾和污水等）經厭氧發酵處理產生的沼氣，驅動沼氣發電機組發電，并可利用發電機組的余熱用于沼氣生產，使綜合熱效率達80％左右，大大高于一般30~40%的發電效率，用戶的經濟效益好。

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.沼氣發電機組對沼氣有什么要求？

2. What are the requirements for biogas generator set?

沼氣中雜質含量如Si、HS等應控制在某范圍內，沼氣的溫度為10~60℃，壓力為0~5kpa，具體見沼氣的氣質要求，一般禽畜糞厭氧處理的沼氣能滿足發電的氣質要求，污水處理沼氣需要脫硫等處理，垃圾填埋沼氣需要脫水等處理。

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.發出來的電能否與電網6300V或10000V變壓器相聯？電網允許嗎？

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

沼氣發電機組的輸出電壓為400V，可以與6300V或10000V變壓器低壓端相聯，若低壓線路長，400V可以升壓到6300V與供電局進線相連；若不上網送發電，為防止向網上倒送電加逆功率繼電器保護，對電網運行沒有影響。這種發電方式供電局不會責疑。

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.沼氣濃度變化時，能否發電？

4. Can power be generated when biogas concentration changes?

發電機組照常可以運行，機組調整后可正常發電或降低發電量。

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

5.發電設備所需廠房條件怎么樣？

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

兩臺沼氣發電機組上網發電1000KW，廠房所需面積（含壓縮機房、控制室、值班室）200平方米左右，廠房為普通廠房就可以。

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.沼氣發電設備投資回收期多長？

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

包括發電機組在內的附屬設備投資，若電費每千瓦時為0.6元，回收期為8個月，每千瓦時為0.5元，回收期為10個月左右，每千瓦時為0.4元，回收期為12個月。

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.沼氣發電一方氣發多少電？

7. How much electricity does biogas generate?

一度電運行成本（大修費用，財務費用，設備折舊）多少？一臺設備一年運行多長時間？500KW發電機組，每月上網電量多少？一臺設備運行多長時間大修？大修需多少時間？費用多少？

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?

一方氣發1.7KW.hr左右（沼氣中甲烷濃度按照50%計算）。每千瓦時（含大修費，財務費用，折舊費用）運行費用為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.設備運行人員需多少？

8. How many equipment operators are needed?

1~3臺設備每班需要人員1~2人，維修人員1人。

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

9.沼氣發電機組使用壽命為多長時間？

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

使用年限在20年以上，一年實際上網發電時間在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.
