Consideration on Selection of Biogas Generator Sets
1. Reference Suggestions on Type Selection of Biogas Generators
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.
II. Reference Suggestions for Type Selection and Fragmentary Configuration
1. Choose the appropriate installed capacity according to the output of biogas to prevent equipment idle or waste of biogas.
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. 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. High power generation efficiency of biogas generating units means that more electricity can be recovered when gas is consumed in the opposite direction.
5. High on-line rate of gas-fired generating units means less downtime, less methane waste and more power generation.
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. 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. 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. Complete spare parts storage can greatly prolong downtime and add power generation.
10. Whether the maintenance team can arrive at the site in a short time is very important to ensure the operation time.
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.
