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.
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.”

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
