Coal-fired power generating stations are increasingly aware of popcorn ash “plugging” their SCR catalysts, and thus, their catalyst lifecycle replacement models as well. Although experts from SCR catalyst manufacturers rarely predict significant plugging of the catalyst face from LPA or popcorn ash in the design stage of a SCR retrofit project, all too often a […]

Recently, IGS provided surface protection for a large utility with a 265 MW CE coal-fired boiler with Low Nox Burners and SOFA. The varying wastage rates in the different areas of the boiler, mix of erosion and corrosion issues, and previous poor performance of the existing thermal spray coating lent itself well to an IGS […]

IGS recently performed automated weld overlay on the nose arch of a large power utility’s Units 1 & 2, 640mw Foster Wheeler boilers. Unit 1 was accomplished in the fall. The quality of the work was at a level that we were the preferred vendor for the work on Unit 2 in the spring. The […]

Recently, IGS’s non-union Mechanical group performed a change-out of the boiler air preheater baskets and the top layer of SCR catalyst at a coal-fired power plant. The company rotated the air preheater, replaced 96 hot end baskets, 144 cold end baskets, and radial seals in a Ljungstrom 26.5 – V152 air preheater. Two 10 man crews were utilized […]
