Cogeneration units are modular plants for producing heat as well as electrical energy, making use of the principle of the power-heat coupling for this purpose. Essentially, they are based on a combustion engine driven with gas, diesel, wood, or other fuels. In simple terms, the motor powers a generator which converts the kinetic energy of the rotational movement into electrical energy. The heat generated during the combustion process is usually used for heating. In the precise application of a plant with a power of several ten megawatts, elastic jaw couplings of the RINGFEDER® TNM series are ideal for establishing the connection between the gas motor and the generator. They effectively and reliably ensure the torque transmission and, due to their universal flexibility, effectively compensate for both shaft displacements and unintentional torsional vibrations. Furthermore, the TNM couplings are extremely temperature-resistant, require very low-maintenance and are installation-friendly.
