Combined heat and power modules are compact energy generation units that provide a de-centralised (local) supply of heat and power with a consumer focus at an overall efficiency of around 90%. Compared with a separate energy supply with power from a condensing power plant and heat from a boiler, primary energy savings of well over 30% can be achieved. This is also linked to a corresponding reduction in pollution. Depending on the fuel comparison, this means the emission of up to 25% less nitrogen oxide (acid rain) and around 60% less carbon dioxide (greenhouse gas).
An internal combustion engine is supplied with natural gas and combustion air from the installation room. This energy is converted into mechanical energy by the engine. A synchronous generator is powered via the coupling. This generates 400 V and 50 Hz three-phase current.
