Since 1993 the annual exhibition and conference for the European energy industry presents new developments on the topics such as renewable energies, power plant technology as well as distributed energy generation. Since then the Power-Gen is deemed to be the leading trade fair for the power technology and energy industry in Europe, which takes place at changing locations every year. For the 25^th issue of this trade visitor fair with its accompanying internationally oriented congress, organisers PennWell (UK) selected Cologne (Germany).

Gas turbines are available in many different designs and the power output of the individual models varies considerably – from 200 kW to more than 400 MW. The performance of gas turbines for industrial applications typically ranges from 5 to 40 MW. Dependent on the power, the speeds vary from 3,000 rpm to 15,000 rpm. Please see below which couplings are typically used and which are the selection criteria.

The demands made on the components in combined heat and power plants (CHP) are increasing. They have to be efficient, long-lasting and, in case of an emergency, must at least fulfill the safety requirements set forth by the Medium Voltage Guideline. Thomas Marterer, Product Manager at RINGFEDER POWER TRANSMISSION, explains how operators of CHPs can find the correct coupling for their plant: The coupling should withstand high temperatures and be neither torsionally too stiff nor too soft.
