沼气发电机组选型需思索的问题

Consideration on Selection of Biogas Generator Sets

一、沼气发电机组选型参考建议

1. Reference Suggestions on Type Selection of Biogas Generators

目前国际沼气发电项目中,以出口品牌爲主,次要有瓦克夏、颜巴赫、卡特比勒、高斯科尔、道依茨、德国曼等。国产机组虽然功能方面存在一定差距,但价钱昂贵。

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、选型和零碎配置参考建议

II. Reference Suggestions for Type Selection and Fragmentary Configuration

1.依据沼气产量选择适宜的装机容量,防止设备闲置或沼气糜费;

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

2.1000KW左右的沼气发电机组市场占有率高,性价比也是高的,维护、维修、颐养费用比拟低;

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.多台机组时,宜选用1000KW左右的同一规格,以降低运转费用和备件贮存。在台数较少时,选择一台功率较小的。比方一台1000KW加一台500KW,便于在气质变化较大时调理输入功率,保证机组在70%以上的功率下输入;

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.

4.沼气发电机组发电效率高意味着在耗费相反的燃气时能收回更多的电;

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

5.燃气发电机组在线率高意味着停机工夫少,糜费的沼气少,发电量多;

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

6.气体纯洁时,或许气体处置妥当时,机组一个大修期可达50000~60000小时,普通可达30000~40000小时。但有些机组只达10000~20000小时;

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.沼气中含有微量的腐蚀性成分,对机油形成净化,其耗费量比运用自然气时要大,机油是一种次要的耗费品,在运转本钱中占有一定份额。而不同品牌机组的机油耗量差别较大;

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.

8.零配件价钱无数倍之差,特别留意耗材,比方火花塞价钱。间接关系到运转费用;

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.完全的零配件储藏可大大延长停机工夫,添加发电量;

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

10.维修队伍能否短工夫抵达现场,对保证运转工夫至关重要;

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

11.燃气发电机组是一种大型宝贵设备,应着重于久远的综合评价。综合性价比比价钱更重要。

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.
