Sustainable and efficient
The great energy efficiency of the cogeneration plants is due to the use of the heat generated as a by-product of electricity generation, saving the primary energy of the system. By producing electricity and consuming it in the same facility, energy loss is avoided, achieving greater overall energy efficiency.
One genset for various types of energy
Cogeneration refers to the simultaneous production of two or more types of energy in a single integrated process. Typically, electricity and heat are produced, although it could also be mechanical energy, heat and/or cooling. Cogeneration is used in industry for heat-intensive and electro-intensive processes, as well as in large buildings where heat can be used for heating systems, for cooling through absorption systems, and for domestic hot water in large shopping centres, hospitals, etc.
In a cogeneration process using a reciprocating internal combustion engine, fuel efficiencies rise sharply to over 80% compared to 35% of the purely mechanical energy (which can then be converted into electrical energy).
These types of smaller systems compared to large combined cycles (gas and steam turbine with 65% efficiency) are becoming more widespread, given their high efficiency and response to basic energy needs (electricity, heat and cold), close to the point of consumption, in turn avoiding large installations and, more importantly, power transmission losses, further increasing efficiency whenever possible.
We have the solution for each case, from complex emergency systems for a network service to a simple generator set to install in a small restaurant or shop. We always study your needs, design personalized products and respond with a highly prepared after-sales service.
Development of a cogeneration set
In line with the energy needs of the client’s installations, each and every one of the main components of the equipment is calculated and sized: engine, alternator, heat exchanger for engine cooling, heat exchanger for engine exhaust gases, pumping systems, operation and handling controller, all with a view to maximising the energy efficiency of the fuel used.
Depending on the energy requirements, priority is given to electricity generation via the alternator, low-temperature heat generation from the engine or high-temperature heat generation from the exhaust gases.
Standard components of a cogeneration set:
- Internal combustion engine (diesel, natural gas, LPG, biogas, biomethane, syngas, etc.)
- Alternator to generate electric current
- Liquid/liquid plate heat exchanger for energy utilisation of engine heat (low temperature)
- Gas/liquid heat exchanger for energy recovery from exhaust gas heat (high temperature)
- Control panel with integrated controller
- Electric starter batteries
- Fuel tank or mains-fed system
- Supporting base of the set
- Anti-vibration mounts
