沼氣發電機組選型需思索的問題

D88尊龙Consideration on Selection of Biogas Generator Sets

D88尊龙一、沼氣發電機組選型參考建議

1. Reference Suggestions on Type Selection of Biogas Generators

目前沼氣發電項目中,以出口爲主,次要有瓦克夏、顏巴赫、卡特比勒、高斯科爾、道依茨、德國曼等。國產機組雖然功能方面存在一定差距,但價錢昂貴。

D88尊龙At present, in the international biogas power generation projects, export brands are the main ones, followed by Wakshire, Yanbach, Caterpillar, Gauss Cole, Dowitz, German Mann and so on. Although there is a certain gap in the function of domestic units, the price is expensive.

二、選型和零碎配置參考建議

D88尊龙II. Reference Suggestions for Type Selection and Fragmentary Configuration

1.依據沼氣產量選擇適宜的裝機容量,防止設備閑置或沼氣糜費;

1. Choose the appropriate installed capacity according to the output of biogas to prevent equipment idle or waste of biogas.

2.1000KW左右的沼氣發電機組市場占有率高,性價比也是高的,維護、維修、頤養費用比擬低;

D88尊龙About 2.1000KW biogas generating units have a high market share and cost-effective ratio, and the cost of maintenance, maintenance and maintenance is comparatively low.

3.多臺機組時,宜選用1000KW左右的同一規格,以降低運轉費用和備件貯存。在臺數較少時,選擇一臺功率較小的。比方一臺1000KW加一臺500KW,便于在氣質變化較大時調理輸入功率,保證機組在70%以上的功率下輸入;

3. When there are more than 1000KW units, the same specifications should be selected to reduce operating costs and spare parts storage. When the number of stations is small, choose one with smaller power. For example, a 1000KW unit plus a 500KW unit can adjust the input power when the temperament changes greatly, and ensure that the unit input at more than 70% of the power.

沼氣發電機組

D88尊龙4.沼氣發電機組發電效率高意味著在耗費相反的燃氣時能收回更多的電;

4. High power generation efficiency of biogas generating units means that more electricity can be recovered when gas is consumed in the opposite direction.

D88尊龙5.燃氣發電機組在線率高意味著停機工夫少,糜費的沼氣少,發電量多;

5. High on-line rate of gas-fired generating units means less downtime, less methane waste and more power generation.

6.氣體純潔時,或許氣體處置妥當時,機組一個大修期可達50000~60000小時,普通可達30000~40000小時。但有些機組只達10000~20000小時;

6. When the gas is pure, perhaps when the gas is properly disposed of, the overhaul period of the unit can reach 50,000-60,000 hours, and the normal period can reach 30,000-40,000 hours. But some units only have 10,000 to 20,000 hours.

7.沼氣中含有微量的腐蝕性成分,對機油形成凈化,其耗費量比運用自然氣時要大,機油是一種次要的耗費品,在運轉本錢中占有一定份額。而不同機組的機油耗量差別較大;

D88尊龙7. Biogas contains a small amount of corrosive components, which can purify the oil. The consumption of biogas is larger than that of natural gas. Oil is a minor consumable, which occupies a certain share of the operating cost. The oil consumption of different brand units is quite different.

D88尊龙8.零配件價錢無數倍之差,特別留意耗材,比方火花塞價錢。間接關系到運轉費用;

D88尊龙8. The price of spare parts varies by many times. Pay special attention to consumables, such as the price of spark plugs. Indirectly related to operating costs;

9.完全的零配件儲藏可大大延長停機工夫,添加發電量;

9. Complete spare parts storage can greatly prolong downtime and add power generation.

10.維修隊伍能否短工夫抵達現場,對保證運轉工夫至關重要;

10. Whether the maintenance team can arrive at the site in a short time is very important to ensure the operation time.

11.燃氣發電機組是一種大型寶貴設備,應著重于久遠的綜合評價。綜合性價比比價錢更重要。

11. Gas-fired generating unit is a large-scale valuable equipment, which should focus on long-term comprehensive evaluation. Comprehensive price is more important than price.
