At Turow, Poland Derakane replaces borosilicate glass
The FGD (Flue gas desulfurization) unit operates at a temperature of 160 F (70C) under normal conditions. However, during the construction period, two of the four units were not operative and ran in the bypass mode. During the by-pass operation one of the units ran for two years at temperatures up to 320F (160 C). The previous chimney liners were constructed of borosilicate blocks which needed to be replaced due to the wet circumstances and the huge swings in temperature 70 – 320 F (20 – 160 C). Each of the four units consisted of a chimney liner 17 feet (5.3 m) in diameter and 395 feet (120 m) tall. In addition, there was a total of 1100 feet (330 m) of ductwork with the same diameter. FRP fabricated with Derakane 470HT was selected for this project due to its chemical resistance to the wet flue gas and its ability to manage the huge swings in temperature up to and beyond 320F (160 C).

Don Kelley, Senior Scientist at Ashland Performance Materials, provided lots of examples to demonstrate that FRP made from Epoxy Vinyl Ester Resin compares favorably to acid brick-lined carbon steel, stainless steel and high alloy clad carbon steel for stack and duct applications. There has also been widespread use in scrubber vessel design. A new generation of resins provided clarity and therefore easy inspection. Derakane 510B-400 epoxy vinyl ester resin is good for 227°F and ideal for FGD. For constant operation to 275°F there is Hetron® FR998-35.

Corrosion Issues in and Materials for Power Plant APC Systems Webinar - Part 2 - January 7, 2011.
Three speakers discussed the latest developments in materials for corrosion prevention or reduction for the various APC equipment in a typical coal-fired power plant based on plant specific site conditions, capital cost, maintenance and life time and provided an update of the current developments, on-going testing or performance of installations of corrosion resistant materials or new technology being developed at their respective companies.
