Background

The Gheco-One power plant is owned by Glow Energy. This facility is a 660mw coal fred power plant and is situated in the Map Ta Phut area of Rayong in the gulf of Thailand .The Plant’s  onstruction was completed in 2011 and in 2015 Glow Energy received the Best Public Company 2015 Resources Industry Award. With regards to the renewable energy business, Glow group has developed Glow energy solar power plant, in order to promote electricity generation from renewable energy. Glow Energy Solar is the frst solar power plant in Rayong
Province.

Operating Conditions

This new supercritical coal fred power plant is designed to be environmentally friendly, by reducing fuel consumption, whilst maximizing power generation. Supercritical boilers produce power  ore effciently than standard boilers, as they operate with start up valves and waterwall pressure controls, but because they operate at higher pressures and higher temperatures, a proven reliable lining system was specifed to withstand these constant aggressive demands.

Special Requirements

Trepax are now asked to perform installation and repair work at annual shutdowns at Gheco One, due to the excellent work that was carried out on our frst major project here in 2015.

The following works were undertaken…

We were asked to install flake lining coatings to the Absorber/GGH Duct.

FRP linings were installed to repair concrete structures and to repair leaking pipe work….Pipe wrapping with FRP.

Application of epoxy flooring to maintenance workshop and Chimney insulation work were other areas where our services were required

Corrosion Protection

Flake lining coatings were applied to the Absorber/ GGH Duct, to maintain corrosion protection to these highly aggressive and corrosive environments. FRP lining work was carried out in several areas within the plant to upgrade and protect from chemical attack.

System

1. Trowel applied, reinforced monolithic lining system for high acid resistance.

2. High build heavy duty glass flake novolac epoxy coating for high temperatures.

3. High solids epoxy intermediate coating system giving optimum adhesion for topcoats.

These systems were applied to protect against high temperatures, chemical and abrasion attack and were selected and specifed for there  erformance
