Great River Energy’s Coal Creek Station in Underwood, N.D., is fueled 100 percent by lignite coal. Because the pyrites and ash from the lignite are abrasive to the power plant’s pipe lines, Coal Creek had problems with leaking in its pulverizer reject lines. Plant personnel searched for a way to mitigate the effects of this leaking and extend the pipes’ life. They found that wear resistant basalt- and ceramic-lined piping extended the reject piping’s life and reduced maintenance requirements.
KALDETECT is a system for monitoring wear. It provides early and reliable warning of when piping or plant components are approaching their end-of-life. It therefore prevents unplanned downtime and repairs and well as any environmental or equipment damage.
One of our customers is a plant manufacturer that is among Europe’s biggest producers of boilers used in coal-fired power stations and waste incineration plants. En route to the burners, the coal dust pipelines branch into the so-called “coal dust distributors”. Their complex geometries and the high velocity of the abrasive medium subject them to extreme wear.
Coal is one common raw material for the manufacture of coke, which is used as the fuel for blast furnaces. One leading steel producer in India therefore runs its own coal mines in the country. These sites have their coal washeries which employ “dense media” cyclonic separators.
For more than 15 years, Kalenborn has been a reliable partner for wear protection solutions in the Brazilian market. Every year, we supply hundreds of kilometers of wear-resistant pipes to customers in various industries, including mining, steel and cement production.
At our Vettelschoss site, we are continuing to invest in improved laboratory facilities: Two new, high-performance furnaces will help in investigating resistance to wear and impact, resistance to temperature fluctuations and the quality of surfaces for our materials. Our objective is to optimise the properties and manufacturing processes for our products and thus to further improve their quality.
On 20.09.2017 the IHK, Germany’s industrial chamber of commerce, held its honour awards for the best in examinations at the Rhein-Mosel-Halle in Koblenz. One of around 400 former trainees, Maximilian Pischel, was given an award by the Industrie und Handelskammer (IHK) of Koblenz for excellent results in his examinations to become an industrial business specialist according to the central Rhine model.
At its factory in Ghent, one of the largest steel producers in the world makes steel products for a wide variety of applications, e.g. in the automotive and building industries. The plant has two blast furnaces, which are continuously filled with coke, sinter and pellets. The result is production of 4.8 million tonnes of pig iron every year.
Iron ore is a key raw material which is extracted as rock from ore mines. Various industrial processing steps refine the ore till it is in the form of pressed pellets. It is in this form that the ore is used for the manufacture of steel. Our customer is the world’s leading producer of iron ore pellets. Right from the founding of Kalenborn do Brasil 15 years ago, the company has been supplying the producer with wear protection solutions for various pieces of plant.
