今天我们济南燃气发电机组厂家小编给大家介绍的是燃气发电机应该如何选型?
Today, we Ji'nan gas turbine manufacturers to introduce a small series of gas generators should be how to type?
一、沼气发电机组选型参考建议
A reference for the selection of biogas generating units
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、道依茨、德国曼等。国产机组虽然性能方面存在一定差距,但价格低廉。
At present domestic biogas power generation project, dominated by imported brands, mainly Waukesha, jenbacher, DEUTZ, Germany's man. Although there is a certain gap between the performance of domestic units, but the price is low.
二、选型和系统配置参考建议
Two, type selection and system configuration reference recommendations
1、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、保养费用比较低;
1000KW about the market share of biogas generating units is the highest, price is also the highest, maintenance, repair, maintenance costs are relatively low;
2、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;
when more than one unit, it is appropriate to use the same specifications of the 1000KW, to reduce operating costs and spare parts storage. The number of small, choose a smaller power. For example, a 1000KW plus a 500KW, easy to adjust the output power in a large amount of gas change, to ensure that the units in more than 70% of the output power;
3、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;
according to the appropriate selection of gas production capacity, to avoid idle equipment or waste of methane;
4、沼气发电机组发电效率高意味着在消耗相同的燃气时能发出更多的电,燃气发电机组在线率高意味着停机时间少,浪费的沼气少发电量多;
the high efficiency of biogas generating units means that in the same gas consumption can send more electricity, gas generating units online rate means less downtime, less waste gas power generation;
5、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。但有些机组只达10000~20000小时;
gas purity, or gas treatment was at the time, a major overhaul period of up to 50000 ~ 60000 hours, generally up to 40000 ~ 30000 hours. But some units only reach 20000 ~ 10000 hours;
6、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。而不同机组的机油耗量差异较大;
biogas containing trace of corrosive components, oil pollution, the consumption will be greater than the use of natural gas, oil is a kind of main consumables, in operation cost occupies a share. But the difference of oil consumption of different brand units is great;
7、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,齐全的零配件储备可大大缩短停机时间,增加发电量。
the price of spare parts have many times the difference, pay special attention to supplies, such as spark plug price. Directly related to the operating costs, complete spare parts reserves can greatly shorten the downtime, increase the power generation.
