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.

Why Every Component of a Cement Mill Counts in the Production Process

By Björn Schumacher on Jan 18, 2017

Operators of cement plants worldwide face the challenge to create their systems more efficient and reliable. Even though the production and consumption of this material is quite stable in Europe, there is a continuously growing demand in Africa, North America and Asia. For this reason, production needs to be optimized and therefore all components which are part of the drive to guarantee constant operation, minimal downtimes and low maintenance costs.

Couplings for the safe operation of piston engine-powered CHPs: not too soft, not too stiff

By Sophie Keil on Oct 12, 2016

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.

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.
