Engine Generator Sets refer to the device which uses internal combustion engines (i.e. engine generator sets) as prime mover to drive alternators to generate electrical energy. It is a power generation equipment that converts heat energy into mechanical energy, which is then converted into electrical energy and heat energy, and has the advantage of small size, high thermal efficiency, and good start-up performance. It can burn Liquid fuels, gas and dual fuel. For more Fuels information, please vist here: Fuels .
Classification of Engine Generator Sets:
1. According to the different fuels used, the engine generator sets can be divided into three categories: Liquid fuel generator sets, Gas generator sets, and Dual fuel generator sets.
■ Liquid Fuel Generator Sets, It can be classified into Diesel generator sets, Heavy fuel oil generator sets, Crude oil generator sets, Liquid biofuel generator sets, etc.
■ Gas Generator Sets, It can be classified into Natural gas generator sets, Coal mine gas generator sets, Gaseous biofuel generator sets, Coal gas generator sets, Industrial off-gas generator sets, etc.
■ Dual Fuel Generator Sets, including Natural gas dual fuel generator sets, Ammonia dual fuel generator sets, Methanol dual fuel generator sets, etc.
2. According to the different engine speeds, the engine generator sets can be divided into three categories: High-speed generator sets (n > 1000 r/min), Medium-speed generator sets (300 < n ≤ 1000 r/min), and Low-speed generator sets (n ≤ 300 r/min).
3. According to their usage, the engine generator sets can be classified into Land-based generator sets, Marine generator sets, and Special generator sets. wherein the Land-based generator sets including Stationary generator sets and Mobile generator sets；wherein the Special generator sets can be further classified into Enclosed generator sets, Mobile generator sets, and Emergency generator sets.
Characteristics of Medium Speed Engine Generator Sets:
1. Compared with high-speed Engine gensets, the advantages of medium speed Engine generator sets:
■ Durability (Low component wear, overhaul time of 60000 to 80000 hours);
■ Reliability (Low failure rate, suitable for continuous operation);
■ Economy (Fuel consumption as low as 185 g/kW.h, Low maintenance costs);
■ High efficiency (Generation efficiency of over 45%).
2. The disadvantages are relatively Large volume and heavy weight, relatively high one-time investment cost.
Engine generator sets are widely used in industrial, mining, power plant, oil field, traffic, communication, construction and other fields. There are all kind of internal combustion engine gensets in our business scope. Such as high speed four stroke internal combustion engine gensets, which power range from 7.6 kW to 3,000 kW. Medium speed four stroke gas internal combustion engines gensets, which power range from 0.4 MW to 21 MW. Low speed two stroke generator set, which power range from 4.0 MW to 77 MW.
