With the increasing demand for environmental protection, in order to improve the current situation of severe haze, more and more power companies will abandon thermal power generation and switch to gas power generation. At present, there are many resources that can be utilized, which are not only environmentally friendly but also meet market electricity demand. At present, the mainstream fuel for power generation is mainly natural gas, followed by coalbed methane, gas, biogas, petroleum associated gas, and shale gas in the future. So the market prospects for gas power generation are promising, but many homeowners face many problems in selecting gas power generation units. Below, I will introduce to you the selection and precautions of gas generator sets.
(1) Select appropriate installed capacity based on biogas production to avoid equipment idle or biogas waste;
(2) Units with a market share of around 1000KW have a high cost-effectiveness, and maintenance, repair, and upkeep costs are relatively low;
(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) High power generation efficiency means that more electricity can be generated when consuming the same amount of gas;
(5) A high online rate means less downtime, less waste of biogas, and more power generation;
(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. But some units only reach 10 natural gas power generation units for 000-20000 hours;
(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) 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) A complete reserve of spare parts can greatly shorten downtime and increase power generation;
(10) Whether the maintenance team can arrive at the site in a short period of time is crucial to ensuring operational time;
(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) The type of gas determines the choice of gas generator set. Natural gas generators may not necessarily be able to burn biogas or gas.
(13) To understand the composition of the gas and the concentration of methane in the gas. In order to make the next step in selecting gas generator sets, especially oilfield associated gas and gas.
