Combined heat and power
What is combined heat and power (CHP) generation?
CHP is the simultaneous generation of electric power and heat in a single plant. A special case is trigeneration, i.e. the combined generation of heat, power, and cooling energy.
The advantage of combined heat and power generation is the particularly efficient use of fuel. Compared with separate heat and power generation, the efficiency factor is significantly higher.
Would combined heat and power generation be of interest for me?
CHP plants are most efficient, if the generated heat as well as the electric power is used directly on-site. The revenue of a CHP plant can be determined from the amount of heat used, the reduction of purchased electricity, and possible subsidies according to the Renewable Energy Law as well as possible funding, e.g. for heat storage, heating & cooling networks, etc.
Apart from fossil fuels, CHP plants can also be fired with alternative fuels such as bioethanol, wood chips or pellets.
Typical industrial CHP applications are:
What can we do for you?
Within the scope of an initial feasibility study, the following steps should be planned and worked out conceptually:
eta projects with CHP plants
Various energy saving options have been studied in detail. The cost-effectiveness of an existing CHP was also analyzed under the changed conditions (new legal requirements). In addition, a call for tenders for electricity and natural gas including contract documentation was carried out.
The realization of innovative steam generation with combined heat and power production consisting of a conventional steam boiler with micro gas turbine and GTA burner (gas turbine exhaust gas burner), renewal of the steam distribution with clean steam generators and a new ventilation system for the supply of high-hygiene areas were able to reduce the CO2 emissions by almost 20 %.
Pre-feasibility study Renolit
The technical feasibility and economic viability of different variants for CHP (combined heat and power) and CHP (combined heat and power) have been analysed. The following technical variants were analyzed more detailed: CHP with use of the heat for absorption refrigeration, micro gas turbine.
Stahlgruber GmbH - Sulzbach-Rosenberg
A concept has been developed that provides a reduction in the heat input through the roof windows, improvements to the air curtains and a higher cooling capacity. The heat supply is most economically by a central generation with combined heat and power. The additional costs paid off against the separate supply in 4.3 years.
