沼气发电机组的机型怎么选择?

一,沼气发电机组选型参考倡议

1. Reference Initiative for Type Selection of Biogas Generators

目前国内沼气发电项目中,以进口为主,主要有瓦克夏、颜巴赫、卡特比勒、高斯科尔、道依茨、德国曼等。国产机组固然性能方面存在一定差距,但价钱低廉。

At present, the main domestic biogas power generation projects are imported brands, mainly Wakshire, Yanbach, Caterpillar, Gauss Cole, Dowitz, German Mann and so on. Although there is a certain gap in the performance of domestic units, the price is low.

二,选型和系统配置参考倡议

II. Selection and System Configuration Reference Initiative

(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) Select the appropriate installed capacity according to the output of biogas to prevent idle equipment 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;

(2) About 1000KW biogas generating units have a high market share and a high 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出功率,保证机组在70%以上的功率下输出;

(3) When there are many units, the same specification of 1000KW should be selected to reduce operation cost 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 output power when the temperament changes greatly, and ensure the output of the unit 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同的燃气时能发出更多的电;

(4) High power generation efficiency of biogas generating units means that more power can be generated when the same gas is consumed;

(5)燃气发电机组在线率高意味着停机时间少,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,或者气体处置得当时,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, or when the gas is disposed of properly, the overhaul period of the unit can reach 50,000-60,000 hours, and that of the general unit 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,对机油形成污染,其耗费量比运用自然气时要大,机油是一种主要的耗费品,在运转本钱中占有一定份额。而不同机组的机油耗量差别较大;

(7) Biogas contains a small amount of corrosive components, which pollutes the oil. The consumption of biogas is larger than that of natural gas. Oil is one of the main consumables and occupies a certain share of the operating cost. The oil consumption of different brand units is quite different.

(8)零配件价钱有数倍之差,特别留意耗材,比方火花塞价钱。直接关系到运转费用;

(8) The price of spare parts varies by several times. Special attention should be paid to consumables, such as spark plugs. It is directly related to the operation cost.

(9)齐全的零配件储藏可大大缩短停机时间,增加发电量;

(9) Complete storage of spare parts can greatly shorten downtime and increase power generation;

(10)维修队伍能否短时间抵达现场,对保证运转时间至关重要;

(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贵重设备,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.
