Cleaner heat without the burn, for buildings and industries worldwide

02.03.2007
The hazardous manual cleaning of heavily clogged boiler pipes can become a thing of the past, thanks to a computer controlled pipe cleaning attachment developed by EUREKA project E! 3237 APCS. But as well as boosting boiler efficiency, it also offers industry far lower cost boiler solutions for heavy duty applications that were until now, unavailable.

Dutch firm Optimum Technologies and French company Maguin, partners in the project, developed a heat resistant mechanical arm to monitor boilers and systematically insert a brush into each pipe, cleaning the boiler while it is still in operation. Typical working temperatures are in the region of 200 degrees centigrade. Computer control enables it to be accurately programmed for each boiler. The system has already been granted a European patent, and a worldwide patent is pending.

Non-stop cleaning

Until this development, the only alternative has been to install water tube boilers, which produce far less fouling. However, they cost 3 to 5 times more than fire tube boilers and only operate at high pressures, of over 35 bars.

Steam is still one of the best ways to transfer heat at a constant temperature, and fire tube steam boilers are widely used in industrial applications, all over the world. The concept is simple, hot gases travel through tubes or pipes placed in water, and their heat is transferred to the water surrounding the pipes. However, using heavy or solid fuels such as coal or biomass to heat the gases causes boiler pipes to clog up and become dirty. This continuously reduces the boiler’s efficiency and in the worst cases, can bring it to a standstill. Cleaning fire tube boilers is an arduous and intensive task considering there are generally over 100 pipes to clean. It involves a loss in production, as the boiler has to be taken out of operation. A long brush is used to scrape each pipe out by hand, exposing the cleaner to the residue of noxious gases in the tubes.

According to Enno Nuy, director of Dutch partner Optimum Environmental Technologies B.V, the innovation is being purchased by industrial plants already using fire tube boilers and by new industries which had no option than to use the more expensive water tube boilers in the past. “Tar production plants and recycling plants in the Netherlands have already installed our system,” he says. Nuy believes the partners will be set to exploit ‘the enormous USA and Chinese markets’ with a worldwide patent.

However, “Without EUREKA funding it wouldn’t have happened,” says Nuy. “All those involved were small companies, EUREKA was vital for the research and development of our system.”

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
