Compined Heat-Power Plant (CHP)

Or “Blockheizkraftwerk” (BHKW)

Principle and Effect of a Compiened Heat-Power Energy Plant:

A combined heat and power unit is a total energy unit which will use the energy created in small and mid sized homes with greater efficiency.
The engine also drives a generator which generates electricity.
The heat originating from the process is transferred over to the heat exchanger for heating purposes and to the hot-water production. The electric energy is used predominantly for personal use, the rest is fed against reimbursement (that´s different from country to country} into the public net.
The concurrent production and use of electric power and heat is called a combined heat and power unit.
The efficiency lies at 90% and higher.
Compared with the consumer-distant electric power production in mainstream power stations, decentralized productions, on an average 2/3 of the energy will by lost, during change and transportation, which is a high environmental advantage for the CHP because of the strong CO reduction.

Efficiency:
A Mini CHP can be used in a building with no external connections to any energy supplying network. From a pure economic point of view 4000 operating hours should be reached.

In bigger buildings and heat groups a CHP runs optimally if more than 30% of the heat needed is not covered by the basic load, presuming that the CHP is used predominantly for heat production, and electricity production is just a by-product. At peak usage a boiler must cover the load, while the CHP keeps working.
In self sustaining operation of a CHP, a buffer memory must be used to prevent the frequent turning on and off, to reach ideal production life terms in the unit and also wear and other investment losses are avoided.

Fuel materials:
A traditional CHP is fueled by fossil based energy sources.
More ecologically friendly way to fuel is the use of grow again raw materials {resources}, like vegetable oil, biodiesel, fermentation gas, wood pellets, and also wooden chips or shreds.
If the unused electricity can be fed back against reimbursement into the public net (like in Germany), one can value this as a considerable factor at the amortization of the arrangement.
