All power plants are faced with the challenge to fulfill the high expectations of maintaining peak operating performance while meeting environmental, legal and safety requirements. Operating reliability and a long service life of expansion joints are therefore crucial as unexpected plant shut-downs can be disruptive and costly.

A power plant is divided into a "hot" and a "cold" area. In the "hot" area, the temperature load and the loading of the flue gas with fly ash is decisive. In the "cold" area the
expansion joint is affected by the formation of aggressive condensate, due to the temperature falling below the dew point.

KE® Fabric Expansion Joints are installed in coal-fired power plants, including the coal mill inlet and outlet:

• Coal dust lines
• Secondary lines
• Return suction ducts

Coal dust lines and the expansion joints installed here require a special design to prevent the coal dust from settling and possibly igniting within the lines.

EagleBurgmann Expansion Joint Solutions has proved that the high quality standard for maintaining reliable expansion joints is dependent on selecting the right design and the best materials for the existing operating conditions.
