Within the scope of the specialist laboratory test
"Function and application possibilities of a gas engine driven combined heat and power unit (CHP)", knowledge about the basic function of a CHP unit, its application possibilities as well as its energetic investigation shall be imparted. To this end, experiments will be carried out on a mini cogeneration unit of the ecoPOWER 4.7 type and evaluated by the students. The CHP is to be placed in the overall context of the energy industry with the help of the basic knowledge acquired and evaluated from an economic and ecological point of view using two example objects. CHP is defined as the simultaneous extraction of mechanical, electrical and thermal useful energy from other forms of energy by means of a thermodynamic process in a technical plant. This process can be implemented both in large-scale power plants with thermal outputs of up to several hundred megawatts and in compact mini cogeneration units with a few kilowatts. The products after the energy conversion of the fuel in the technical plant are electricity and heat. A CHP plant works most efficiently if electricity and heat are used directly on site without large transmission paths, but the use of CHP depends on the heat requirement, since electricity can be transmitted more efficiently and cheaper than heat due to the existing infrastructure of the public electricity grid. Excess electricity fed into the grid is remunerated by the grid operator in accordance with the Combined Heat and Power Act (KWKG).
