What is CHP unit? 


 

TEDOM CHP units are highly sophisticated process units designed for combined production of power and heat.
It is a combination of a combustion engine, a generator, a set of heat exchangers, and a control system by means of local, PC-assisted remote, and even cell-phone control of CHP units.

The small, gas-engine based CHP units are part of the decentralized energy sources. This means that power and heat are produced close to the site of consumption, so that there no longer are losses caused by power transmission and distribution.
The power from CHP unit is either used for internal consumption of the building where a CHP unit is installed or supplied into the grid. The heat from CHP units is utilized to heat buildings, prepare hot service water or process heat. CHP units also serve as backup electric energy sources where this energy must be supplied around-the-clock.
With an absorption cooler, the heat generated in the cogeneration process can be used for the production of cold for technological purposes or air conditioning. In such cases, we speak of trigeneration, i.e.,  combined production of power, heat, and cold.

 

Fuel for CHP units

The dominant fuel used in powering CHP units is natural gas.  

However, the number of facilities that use biogas, landfill gas, sewage gas or other alternative fuels as, for example, mine gas, expands abruptly in recent years.

Distributed power plant

As for other alternative power production methods that make use of such  renewable energy sources as, for example, sun or wind, the greatest benefit of cogeneration is that it is capable of creating precisely the desired amount of energy for any desired time. For this reason, cogeneration is sometimes referred to as controllable energy source. The dispatching control of larger number of CHP units makes it possible to create so-called distributed power plants(sometimes referred to as virtual power plants), i.e., systems composed of numerous smaller power sources in several localities that, from external point of view, function as one single unit with a higher power output. These power plants are capable of providing certain system services, thus compensating for the imbalances in the power supplied by the photovoltaic or wind-based systems, etc.
