關(guān)于沼氣發(fā)電機組九個(gè)實(shí)用問(wèn)題
在使用沼氣發(fā)電機組的時(shí)候,難免會(huì )遇到很多問(wèn)題。在此小編為您總結了沼氣發(fā)電機組九大實(shí)用問(wèn)題,希望能給用戶(hù)帶來(lái)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(fā)電?沼氣發(fā)電機組有什么優(yōu)點(diǎn)?
1. Why biogas power generation? What are the advantages of biogas generator sets?
沼氣發(fā)電機組它利用工業(yè)、農業(yè)或城鎮生活中的大量農業(yè)生產(chǎn)體系廢棄物(例如:酒糟液、禽畜糞、城市垃圾和污水等)經(jīng)厭氧發(fā)酵處理產(chǎn)生的沼氣,驅動(dòng)沼氣發(fā)電機組發(fā)電,并可利用發(fā)電機組的余熱用于沼氣生產(chǎn),使綜合熱效率達80%左右,大大高于一般30~40%的發(fā)電效率,用戶(hù)的經(jīng)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(fā)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(zhì)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(jiàn)沼氣的氣質(zhì)要求,一般禽畜糞厭氧處理的沼氣能滿(mǎn)足發(fā)電的氣質(zhì)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(fā)出來(lái)的電能否與電網(wǎng)6300V或10000V變壓器相聯(lián)?電網(wǎng)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(fā)電機組的輸出電壓為400V,可以與6300V或10000V變壓器低壓端相聯(lián),若低壓線(xiàn)路長(cháng),400V可以升壓到6300V與供電局進(jìn)線(xiàn)相連;若不上網(wǎng)送發(fā)電,為防止向網(wǎng)上倒送電加逆功率繼電器保護,對電網(wǎng)運行沒(méi)有影響。這種發(fā)電方式供電局不會(huì )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(shí),能否發(fā)電?
4. Can power be generated when biogas concentration changes?
發(fā)電機組照??梢赃\行,機組調整后可正常發(fā)電或降低發(fā)電量。
The generator set can operate normally, and can generate electricity normally or reduce the output after adjustment.
5.發(fā)電設備所需廠(chǎng)房條件怎么樣?
5. What are the plant conditions required for power generation equipment?
兩臺沼氣發(fā)電機組上網(wǎng)發(fā)電1000KW,廠(chǎng)房所需面積(含壓縮機房、控制室、值班室)200平方米左右,廠(chǎng)房為普通廠(chǎng)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(fā)電設備投資回收期多長(cháng)?
6. How long is the investment recovery period of biogas power generation equipment?
包括發(fā)電機組在內的附屬設備投資,若電費每千瓦時(shí)為0.6元,回收期為8個(gè)月,每千瓦時(shí)為0.5元,回收期為10個(gè)月左右,每千瓦時(shí)為0.4元,回收期為12個(gè)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(fā)電一方氣發(fā)多少電?
7. How much electricity does biogas generate?
一度電運行成本(大修費用,財務(wù)費用,設備折舊)多少?一臺設備一年運行多長(cháng)時(shí)間?500KW發(fā)電機組,每月上網(wǎng)電量多少?一臺設備運行多長(cháng)時(shí)間大修?大修需多少時(shí)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(fā)1.7KW.hr左右(沼氣中甲烷濃度按照50%計算)。每千瓦時(shí)(含大修費,財務(wù)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.
