A CHP cogeneration conventional power stations that burn gas, coal or oil are usually only on an efficiency of 45%. This is because these but not use only the electrical power (force), the heat. This is quite different for power heat cogeneration plants. This uses the resulting current, as well as the heat. As a result the efficiency rises to up to 80-90%.
When a compact of the combined heat and power plant is called a block heat and power plant. An important prerequisite for meaningful operation of cogeneration is a possible continuous heat dissipation. This can be for example a swimming pool or process heat in a factory. But the heat can be used also for heating purposes perfectly. However you must be aware that heat is limited mainly to the heating and reduces the efficiency.
The power is fed normally into the public grid. Is the law for renewable energy Operators of a block CHP plant guarantees a feed-in tariff. The current can be used but of course also directly itself. The most power stations are powered with diesel, gas or biogas. There are now but also power stations on the market, that run on wood pellets and wood chips. So-called mini CHP, which can be used also in double or single family homes are the latest trend in the field of cogeneration. In the face of rising prices for energy, these systems encounter a very great interest. By significantly increasing of the efficiency of a CHP power generation provides a significant reduction of carbon dioxide emissions. This is up to 30%. Cogeneration can thus contribute to the reduction of climate change. Markus boos
