Orlando Utility Commission – HRSG Blowdown Pump Station

Project Assets

Project Description

Romtec Utilities designed, engineered, and supplied two pump stations for a power plant in Orlando, Florida. These pumping systems are used to recirculate extremely hot water as part of a combined-cycle power process that makes use of an HRSG, or heat recovery steam generator. Romtec Utilities used Goulds 10hp turbine pumps in a duplex configuration for one of the pump stations, while the other less powerful system uses duplex Goulds turbine pumps with a 5 stage bowl assembly. Using turbine pumps mount above the sump was an engineering decision due to the near boiling temperatures of the water that is being pumped. This also allowed the pumps to utilize effective and economical air cooling on the motors. Between pumping cycles, blowdown water is stored inside a stainless steel tank with an interior & exterior coating of Thermaline 450 for increased protection against the hot water temperatures. A Vega pulse radar was selected for this industrial application for continuous level measurement for liquids inside the sump and is not affected by the presence of steam.

Why They Chose Romtec Utilities

The Curtis H. Stanton Energy Center is a large power plant that is managed by the Orlando Utility Commission, the 2nd largest municipal utility in Florida. Romtec Utilities was hired to design and supply pump stations to support a combined-cycle power generation process that requires significant amounts of recirculated water to function. After supplying several of these facilities for the private sector, Romtec Utilities began work on an HRSG pumping system designed to handle hot water, steam, and potentially corrosive water due to distillation. The design of the system was completed using information provided by Worley Parsons, OUC’s engineering firm. This project took place over several years and was delivered in multiple phases over this timeline. Once the system was delivered, it was installed by Irwin Industries, a contractor working for OUC. Romtec Utilities sent a field technician to Florida when each pump station was ready for start-up. While on-site our technician tested and performed the initial configuring of the system and trained operating personnel from the Orlando Utility Commission.
