What are the factors that can reduce the service life of a metal bellows coupling?

By Thomas Marterer on Apr 18, 2018

It is generally assumed – and typical applications confirm – that metal bellows couplings reliably work over the entire service life of an installation, if the coupling is correctly designed. In the future, this can no longer be taken for granted as applications are becoming more and more dynamic. Such applications require you to consider additional criteria when selecting and designing a coupling. Read here about the most important factors which have to be taken into account.

Couplings in Aeroderivative Gas Turbines

By Thomas Marterer on Jun 07, 2017

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.

Certification According to the Medium Voltage Guidelines: the Following Applies to CHPs

By Thomas Marterer on Sep 21, 2016

Pursuant to the supplement to the Medium Voltage Guideline in 2013, the certification directives for co-generation plants have been adopted and the obligation to furnish evidence of compliance with the BDEW guidelines of 2009 is now also binding for co-generation plants. As a result, certificates have to be furnished for CHPs connected to the medium voltage grid with reference to their behavior in the event of a failure.

Combined Heat and Power Units Assist in Securing Grid Stability, which particularly Challenges their Gensets

By Thomas Marterer on Sep 14, 2016

The amendment to the obligatory certification within the medium voltage guideline in 2013 catapulted combined heat and power units into a new league: they are now also in charge of stabilizing the dynamic German power supply network. This provides excellent opportunities for the technology, but it also means new obligations.

Reciprocating Engines in Combined Heat and Power Units: Is Higher Power without Loss of Energy Efficiency Possible?

By Thomas Marterer on Aug 03, 2016

The combined heat and power technology (CHP), in particular co-generation units, have long been a part of the industrial energy transition. However, the large potential of combined heat and power units is still underutilized. The reason for this, among others, is because of the properties of the installed drive technology: for instance, the non-uniform torque of reciprocating engines. New components promise more power with consistently good energy efficiency.
