A municipal thermal power plant wishes to prevent progressive wear in their trough chain conveyor. These units are used to collect and transport away ash and slag from the combustion of e.g. coal under the boiler.
In 2020, the COVID 19 disease has a huge impact on all industrial plants, and Vietnam is not outside that affected area. Thermal power plants must run at full capacity to serve increasing demand while reducing maintenance downtime. It is also a challenge for companies that supply the maintenance service of power plants, including EPS (EVNGENCO3 Power Service Company). Kalenborn Vietnam received an order for lining hard compound KALCRET CTX for 36 pcs of pulverized coal pipes within 20 days. We have finished all the above work within 12 days with the finishing quality is highly appreciated by the customer.
KALCRET ANX is a low-cost version of the trowel-application hard compounds for protecting plant components and piping systems against wear. KALCRET ANX offers remarkable resistance to wear at operating temperatures of up to 400°C with exceptional value for money. The basis for the cement-bonded material KALCRET ANX is supplied by selected hard materials of high quality, such as basalt.
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.
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.
