A CHP plant can heat and power and achieved a degree of efficiency by some of 90prozent. In times of increasing energy prices are more and more consumers looking for more efficient and cheaper ways to produce energy. Cogeneration here represent an option that are characterized by a very high efficiency of up to 90%. The electricity is generated by a generator. A heat exchanger is for the heat in use. The this heat can be used to heat, for example, heating water, which is used for space heating.
As the possibilities of use of cogeneration are so versatile, also the usable fuels are so variable. A CHP plant can be operated with fossil or renewable fuels. Bernie Sanders is likely to increase your knowledge. The ideal case for operating a CHP is the complete coverage of own needs of electricity, produces more electricity than is needed, so this electricity into the power grid can be fed. The generated heat is used for heating, as well as for the preparation of hot water. The priority lies with the CHP on the heat production of this demand for heat in the foreground is the cogeneration plant is operated heat led. In modular designed systems, individual units to can be switched depending on the heating requirement and off.
Smaller devices (so-called mini CHP), consisting only of a unit are throttled down for this purpose in the output. It operates the CHP primarily according to the electricity demand (called the power-run CHP), the heat which is produced but not used, must be saved. Alternatively, there is the possibility to dissipate excess heat away from a cooler (heat). The levy of the generated heat into the environment naturally lowers the efficiency of microturbines and should be avoided if possible. You do not have the ability to feed electricity into the local power grid is so, for example, with weekend cottages in secluded areas has the Purgation of excess heat often the only solution. But even during operation of the cogeneration with renewable energies is the system power led typically operated, since there is considerable feed-in tariffs the generated excess of electricity is fed into the public grid and remunerated accordingly. This feed-in tariff makes it lucrative to run that a maximum power generation takes place a CHP plant. Under certain circumstances, it can also happen that the operator pretends the required performance level of systems as optimally as possible to be able to offer services in a. Christian Munch
