沼氣發(fā)電機(jī)在選擇時(shí)應(yīng)該注意什么?
(1)根據(jù)沼氣產(chǎn)量選擇合適的裝機(jī)容量,避免設(shè)備閑置或沼氣浪費(fèi);
(1) According to the output of biogas, appropriate installed capacity should be selected to avoid idle equipment or waste of biogas;
(2)1000KW左右的機(jī)組市場(chǎng)占有率較高,性價(jià)比也是較高的,維護(hù)、維修、保養(yǎng)費(fèi)用比較低;
(2) About 1000 kW units have a high market share, high cost performance, and low maintenance, repair and maintenance costs;
(3)多臺(tái)機(jī)組時(shí),宜選用1000KW左右的同一規(guī)格,以降低運(yùn)行費(fèi)用和備件儲(chǔ)存。在臺(tái)數(shù)較少時(shí),選擇一臺(tái)功率較小的。比如一臺(tái)1000KW加一臺(tái)500KW,便于在氣量變化較大時(shí)調(diào)節(jié)輸出功率,確保機(jī)組在70%以上的功率下輸出;
(3) For multiple units, the same specification of about 1000kW should be selected to reduce the operation cost and spare parts storage. When the number of units is small, choose one with lower power. For example, one 1000kW plus one 500kW can adjust the output power when the gas volume changes greatly, so as to ensure that the unit can output at more than 70% power;
(4)發(fā)電效率高意味著在消耗相同的燃?xì)鈺r(shí)能發(fā)出更多的電;
(4) High power generation efficiency means that more electricity can be generated when the same gas is consumed;
(5)在線率高意味著停機(jī)時(shí)間少,浪費(fèi)的沼氣少,發(fā)電量多;
(5) High online rate means less downtime, less waste of biogas and more power generation;
(6)氣體純凈時(shí),或者氣體處理得當(dāng)時(shí),機(jī)組一個(gè)大修期可達(dá)50000~60000小時(shí),一般可達(dá)30000~40000小時(shí)。但有些機(jī)組只達(dá)10天然氣發(fā)電機(jī)發(fā)電機(jī)組000~20000小時(shí);
(6) When the gas is pure or properly treated, the overhaul period of the unit can reach 50000-60000 hours, generally 30000-40000 hours. However, some units only reach 1000-20000 hours for 10 natural gas generator units;
(7)沼氣中含有微量的腐蝕性成分,對(duì)機(jī)油造成污染,其消耗量比使用天然氣發(fā)電機(jī)時(shí)要大,機(jī)油是一種主要的消耗品,在運(yùn)行成本中占有一定份額。而不同品牌機(jī)組的機(jī)油耗量差異較大;
(7) Biogas contains a small amount of corrosive components, which pollutes the engine oil, and its consumption is larger than that when using natural gas generator. Engine oil is a major consumable and occupies a certain share in the operation cost. However, the oil consumption of different brand units is quite different;
(8)零配件價(jià)格有數(shù)倍之差,特別注意耗材,比如火花塞價(jià)格。直接關(guān)系到運(yùn)行費(fèi)用;
(8) The price of spare parts is several times different. Pay special attention to the price of consumables, such as spark plug. It is directly related to the operation cost;
(9)齊全的零配件儲(chǔ)備可大大縮短停機(jī)時(shí)間,增加發(fā)電量;
(9) Complete spare parts reserve can greatly shorten downtime and increase power generation;
(10)維修隊(duì)伍能否短時(shí)間到達(dá)現(xiàn)場(chǎng),對(duì)確保運(yùn)行時(shí)間至關(guān)重要;
(10) Whether the maintenance team can arrive at the scene in a short time is very important to ensure the operation time;
(11)沼氣發(fā)電機(jī)機(jī)組是一種大型貴重設(shè)備,應(yīng)著重于長(zhǎng)遠(yuǎn)的綜合評(píng)估。綜合比比價(jià)格更重要。
(11) Biogas generator set is a kind of large and valuable equipment, which should be focused on the long-term comprehensive evaluation. Integration is more important than price.
(12)燃?xì)獾姆N類(lèi)決定選擇燃?xì)獍l(fā)電機(jī)組的種類(lèi)。天然氣發(fā)電機(jī)發(fā)電機(jī)組并不一定能夠燒沼氣。
(12) The type of gas determines the type of gas generator set. Natural gas generator set is not necessarily able to burn biogas.
(13)要了解氣體的成份以及氣體里的濃度。以便作下一步的燃?xì)獍l(fā)電機(jī)組選型,特別是油田伴生氣。
(13) To understand the composition of the gas and the concentration in the gas. In order to make the next step selection of gas generator set, especially associated gas of oil field.
