1）根據沼氣產量選擇合適的裝機容量，避免設備閑置或沼氣浪費；

1) Select appropriate installed capacity based on biogas production to avoid equipment idle or biogas waste;

2）1000KW左右的機組市場占有率最高，性價比也是最高的，維護、維修、保養費用比較低；

2) The unit with a market share of around 1000KW has the highest cost-effectiveness, and the maintenance, repair, and upkeep costs are relatively low;

3）多臺機組時，宜選用1000KW左右的同一規格，以降低運行費用和備件儲存。在臺數較少時，選擇一臺功率較小的。比如一臺1000KW加一臺500KW，便于在氣量變化較大時調節輸出功率，保證機組在70%以上的功率下輸出；

3) When multiple units are used, it is advisable to choose the same specification of around 1000KW to reduce operating costs and spare parts storage. When the number of units is small, choose one with lower power. For example, adding one 1000KW and one 500KW makes it easy to adjust the output power when there is a significant change in gas volume, ensuring that the unit outputs at more than 70% power;

4）發電效率高意味著在消耗相同的燃氣時能發出更多的電；

4) High power generation efficiency means that more electricity can be generated when consuming the same amount of gas;

5）在線率高意味著停機時間少，浪費的沼氣少，發電量多；

5) A high online rate means less downtime, less waste of biogas, and more power generation;

6）氣體純凈時，或者氣體處理得當時，機組一個大修期可達50000～60000小時，一般可達30000～40000小時。但有些機組只達10000～20000小時；

6) When the gas is pure or the gas is processed properly, a major overhaul period of the unit can reach 50000 to 60000 hours, generally up to 30000 to 40000 hours. But some units only reach 10000 to 20000 hours;

7）沼氣中含有微量的腐蝕性成分，對機油造成污染，其消耗量比使用天然氣時要大，機油是一種主要的消耗品，在運行成本中占有一定份額。而不同品牌機組的機油耗量差異較大；

7) Biogas contains trace amounts of corrosive components, causing pollution to engine oil. Its consumption is greater than when using natural gas. Engine oil is a major consumable and accounts for a certain share of operating costs. The oil consumption of different brand units varies greatly;

8）零配件價格有數倍之差，特別注意耗材，比如火花塞價格。直接關系到運行費用；

8) The price of spare parts varies by several times, so pay special attention to the price of consumables, such as spark plugs. Directly related to operating costs;

9）齊全的零配件儲備可大大縮短停機時間，增加發電量；

9) A complete reserve of spare parts can greatly shorten downtime and increase power generation;

10）維修隊伍能否短時間到達現場，對保證運行時間至關重要；

10) Whether the maintenance team can arrive at the site in a short period of time is crucial to ensuring operational time;

11）機組是一種大型貴重設備，應著重于長遠的綜合評估。綜合性價比比價格更重要。

11) The unit is a large and valuable equipment, and should focus on long-term comprehensive evaluation. Comprehensive cost-effectiveness is more important than price.

12）燃氣的種類決定選擇燃氣發電機組的種類。天然氣發電機組并不一定能夠燒沼氣或者瓦斯。

12) The type of gas determines the choice of gas generator set. Natural gas generators may not necessarily be able to burn biogas or gas.

13）要了解氣體的成份以及氣體里的甲烷濃度。以便作下一步的燃氣發電機組選型，特別是油田伴生氣，瓦斯氣。

13) To understand the composition of the gas and the concentration of methane in the gas. In order to make the next step in selecting gas generator sets, especially oilfield associated gas and gas.
