Infrared Heat Increases the Up-Time of Gas Power Plant

27.07.2010
Comprehensive and rapid de-icing of intake filters

Gas power plants, which supply electricity to meet peak demands, must work reliably and come on line rapidly, especially in the cold times of the year.

For combustion, gas turbines need air which must be free from dust and other particles and, consequently, this is always pre-filtered. Cold and moist intake air in the winter months can easily lead to icing up of the filters. This means that less air is is passed through the filters so that the turbines must be choked or switched off – just when they are most needed.

At Trianel in Hamm, infrared systems from Heraeus Noblelight complement the de-icing protection in a modern combined cycle power plant (GuD). In just two weeks in May, 24 infrared modules, including controls, were installed and commissioned.

Modern combined cycle (gas and steam turbine) power plants generate electricity at a relatively high efficiency of around 60%, significantly higher than conventional power plants at around 40%. Moreover, they can be brought on line very quickly and so are used for handling medium and peak electricity load demands.

Electricity consumption is not steady but demand is in peaks and troughs. To meet this, fast acting power plants must be used. These can provide high power output within minutes. Gas power points offer such capability and they rely on being able to take in cleaned air. If the in-line filters become iced up, this can lead to power plant shut down. An efficient de-icing system, which above all must operate quickly and reliably, has to guarantee the availability of the power plant even in the cold winter months.

Trianel GmbH is a co-operative of 47 public utilities and operates a combined cycle power plant with two block unit power stations in Hamm. A coal-fired power station is under construction in Luenen and a further one is planned for Krefeld. An offshore wind farm is also underway in front of the island of Borkum. The combined cycle plant in Hamm is already several years old. The experience of the last two relatively hard winters caused Trianel to consider enhancing its existing anti-icing systems. Any solution had to be as easy as possible to retrofit and very responsive.

Thomas Kleinwaechter, manager of technical management and maintenance in Hamm, met with Heraeus Noblelight to investigate the suitability of electrical infrared systems for this application.

As with most gas power plants, the plant in Hamm used the “waste heat” from electricity generation for filter de-icing. This hot air is blown onto the pocket filters, made of fleecy material. However, there can be local cold and hot zones, especially when the hot air is not distributed sufficiently.

In contrast, infrared radiation has significant benefits. Energy is distributed without contact and generates heat within the material itself. In addition, infrared heat is rapidly available and heating is more energy-efficient than many conventional methods.

“I am convinced that infrared systems can heat the filters comprehensively and evenly without significantly impairing the cross-sectional flow of the intake air,” says Thomas Kleinwaechter. The power station operators also made the point that the de-icing enhancement system was a turnkey system which was supplied complete. “We were faced with a real challenge,” says Michael Lyhs, project manager at Heraeus Noblelight, “in the end, there was a window of just three weeks for the total electrical and mechanical installation and this work had to be carried out at heights of 11 to 25 metres.”

Altogether, surface areas of 8.8 x 4m were each fitted with 24 medium wave infrared emitters, with a total rated power of 236 kW. Every three of the 2.20m long emitters are mounted in a frame and these modules can be easily switched on and off and controlled by a switchboard or from the main control room. “The co-operation and collaboration between the power station staff and Heraeus worked so well that the system was up and running in just two weeks!” says Michael Lyhs, delightedly, “I am convinced that the de-icing system will meet the challenges of next winter perfectly.”

Trianel

The liberalised energy market offers public utilities a wide range of opportunities. As the largest European Public Utility Co-operative with 47 members in Germany and the rest of Europe, Trianel has maximised this potential by means of innovative concepts along the total value and supply chain. At the same time, the network of utilities has made possible what would not have been possible for the individual utilities alone – from energy generation in highly efficient power stations through energy trading in our own trading floor up to the development of a broad palette of procurement and marketing solutions.

Trianel also sees future fields of activity for utilities in the areas of re-municipalisation and the use of electric-powered vehicles and is working to develop appropriate solutions with its partners. With its various activities, Trianel represents over 5 million customers.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
