Representative of the Swedish company Sumab Energy - invites you to familiarize yourself with the equipment for generating electricity and heat - cogeneration.
Sumab Energy actively cooperates with European equipment suppliers - MWM, Caterpillar, GE Jenbacher.
Sumab Energy uses in its projects the used MWM, Caterpillar, GE Jenbacher installations with a small amount of work, usually 30-40 000 moto-hours (about 4-5 years), which makes it possible to reduce the cost of the project by 2 times! , compared with the use of new equipment. In this case, all installations are complete. maintenance by qualified personnel and are in perfect working order.
Gas-piston power plants produce electricity from various types of gas fuel. Power plants are functioning:
on natural gas,
biogas,
associated gas,
mine gas.
gas sewage treatment plants,
landfill gas,
blast furnace gas,
coke oven gas, etc.
Gas piston power plants have a simple and reliable design, verified by decades of operation in a variety of climatic conditions. The electric efficiency of gas-piston power stations is considered high, in contrast, for example, from turbines and microturbines, and when working on high-quality natural gas is ~ 39-44%.
This means that to produce the same amount of electricity, in comparison with turbines, gas-piston power plants consume one third (!) Of natural gas less.
Gas-piston power plants are represented in a wide range of single electric power from 800 kW to 4 MW. This power range is basic. That is, in the small and medium range for consumers, you can get almost any value of the electrical power of an autonomous gas-piston power plant.
Almost all models and brands of gas-piston power plants in an expanded configuration are able to operate in cogeneration mode, that is, as thermal power plants. The exhaust gas temperature at the output of the power machine of the gas-piston power plant is ~ 390 ± 10 ° C. This temperature makes it possible to obtain practically free heat energy in the cogeneration mode.
The ratio of electricity and heat energy is 1: 1, that is, 1 MW of installed electric power can receive 1 MW of thermal energy.
The production ratio of saturated steam at a gas piston power plant is 0.5-0.7. Steam can be used for production purposes.
