Engine Power Plants, also known as Internal-combustion Engine Power Plants, refer to the energy station which operate using combustible liquid or gas as fuel, with Internal combustion engine as prime mover to drive the alternator, and convert mechanical energy into electrical energy and thermal energy. Most of them are small and medium power plant under 250 MW, with small investment, short construction term, high reliability and easy maintenance.
Classification of Engine Power Plants：
1. According to the different fuels used, they can be divided into three categories:
■ Liquid fuel Engine Power Plant: refers to an energy station that uses combustible liquids as fuel and with internal combustion engines as the prime mover to drive alternator, converting mechanical energy into electrical and thermal energy.
■ Gas Engine Power Plant: refers to an energy station that uses combustible gas as fuel, and with internal combustion engine as the prime mover to drive alternator, converting mechanical energy into electrical and thermal energy.
■ Dual fuel Engine Power Plant: refers to an energy station that uses both gas and fuel oil as fuels, with the internal combustion engine as the prime mover to drive the alternator and convert mechanical energy into electrical and thermal energy. It can use a mixture of gas (natural gas, synthetic ammonia, or methanol) and fuel oil (diesel or heavy fuel oil) as fuels, or operate solely on fuel in the absence of gas. Dual fuel power plant are suitable for locations with insufficient or unstable gas supply.
2. According to the installation form of Power plants, they can be divided into three categories:
■ Stationary Engine Power Plants, it can be further divided into Factory-style power plants and Containerized power plants.
■ Mobile Engine Power Plants, Including Vehicle-mounted power plants and Trailer type power plants.
■ Marine Engine Power Plants, including Offshore platform power plants and Floating power plants (i.e. Power barges). We can provide classification society certificates according to user requirements.
3. Classified by the speed of the internal combustion engine, it can be divided into three categories:
■ High Speed Engine Power Plant, with engine speed above 1000 r/min, Four stroke.
■ Medium Speed Engine Power Plant, with engine speed 300-1000 r/min, Four stroke.
■ Low Speed Engine Power Plant, with engine speed below 300 r/min, Two-stroke.
Medium-Speed Liquid Fuel Power Plant Benefits:
● High efficiency: Mechanical efficiencies up to 49.0% over.
● Low emissions, fulfillment of worldwide environmental regulations; below World Bank limits.
● High reliability.
● Long lifetime.
● Ease of maintenance, longest safe interval between major overhauls and minimal daily maintenance.
● High operational flexibility, from standby to base load.
● Reliable power supply under all conditions – insensitivity to hot and high-altitude locations.
● Power range from 0.4 MW to 21 MW/unit.
● Power plants with an output of more than 200 MWe.
● Modular concept for flexible capacity extension.
