Base Water-Quality Specs on Reality, Not the GT OEM
Even if you don’t have a steam cycle, chances are your gas-turbine plant uses plenty of treated water—for evaporative cooling or inlet fogging, water/steam injection for NOx control and/or power augmentation. The quality of this water is critical to minimize deposition and corrosion problems.

William Livoti of WEB recommended that power plants assess their pump requirements and consider variable speed drives to reduce energy consumption. He cited the advantages when handling off peak loads. A specific example was given for the VFD saving with cooling water makeup pumps. The number of pumps and potential savings is substantial.

Ion Exchange and Reverse Osmosis
The water treatment plant at a coal and biomass-fired power plant in the Netherlands was 35 years old and needed to be replaced. Ovivo provided an ion exchange and reverse osmosis system which upgraded the boiler feedwater quality to the new standards without replacing the condensate polishing plant.

Improved Reliability of High-AVT (High-pH Water Treatment) Application to Combined Cycle Plants
Generally in the water treatment of combined cycle plants, ammonia and hydrazine are used in the feedwater system and phosphates are used in the boiler system. However, in Mexico, the Tuxpan No. 2 and No. 5 power plants have adopted “High-AVT (high-pH water treatment),” in which ammonia is used to set the pH of feedwater higher than the conventional level, requiring no phosphates in the boiler system. In response to such good operational results, MhI introduced high-AVT as an option for the water treatment of combined cycle plants.

Case study of a GE sodium hypochorite system water treatment installed at Entegra's Union Power Stateion. After the system was installed, the plant steadily reduced chlorine addition to the point it was finally stopped. A follow-up project was done to install a permanent hypochlorite injection system on it as well. Overall chemical cost has decreased by over 10%, a significant dollar amount for a facility of this size.
