1）根据沼气产量选择合适的装机容量，避免设备闲置或沼气浪费；

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

2）1000KW左右的机组市场占有率最高，性价比也是最高的，维护、维修、保养费用比较低；

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）多台机组时，宜选用1000KW左右的同一规格，以降低运行费用和备件储存。在台数较少时，选择一台功率较小的。比如一台1000KW加一台500KW，便于在气量变化较大时调节输出功率，保证机组在70%以上的功率下输出；

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）发电效率高意味着在消耗相同的燃气时能发出更多的电；

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

5）在线率高意味着停机时间少，浪费的沼气少，发电量多；

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

6）气体纯净时，或者气体处理得当时，机组一个大修期可达50000～60000小时，一般可达30000～40000小时。

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.

7）沼气中含有微量的腐蚀性成分，对机油造成污染，其消耗量比使用天然气时要大，机油是一种主要的消耗品，在运行成本中占有一定份额。而不同品牌机组的机油耗量差异较大；

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）零配件价格有数倍之差，特别注意耗材，比如火花塞价格。直接关系到运行费用；

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）齐全的零配件储备可大大缩短停机时间，增加发电量；

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

10）维修队伍能否短时间到达现场，对保证运行时间至关重要；

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

11）机组是一种大型贵重设备，应着重于长远的综合评估。综合性价比比价格更重要。

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）燃气的种类决定选择燃气发电机组的种类。天然气发电机组并不一定能够烧沼气或者瓦斯。

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.
