Natural Gas Combined Cycle Power Plants and Graver

With the tremendous growth in the supply & use of natural gas there is an increased demand for gas fired plants to expand the global electrical generating capacity. With this growth comes the need for more consideration on how to best protect valuable plant assets from premature failure due to issues associated with corrosion product transport and cycling chemistry upsets. Condensate polishing provides a cost effective solution to prevent corrosion product deposition, stabilize cycle chemistry and optimize the start up, restart and operation of natural gas combined cycle (NGCC) units, thus minimizing premature degradation of valuable plant assets.

Graver, a global leader in the supply of Condensate Polishing for the power generation market for more than 60 years, has an array of cost effective technologies to provide solutions to these issues. Graver offers a full range of state-of-the art, cost-effective products designed specifically for treating return condensate in combined cycle power plants. These technologies and systems for condensate filtration and/or ion exchange polishing include; Large Diameter High Flow TurboGuard® disposable filtration systems, AFA® Backwashable filters, skid mounted Powdex® Precoat Demineralizers or deep bed ion exchange polishing systems.

Graver’s products for the natural gas combined cycle market have been designed to address the specific operating modes-, various types of condensers including –Air cooled condensers , and heat recovery steam generators (HRSG) including once through steam generators (OTSG) to mitigate the effects of corrosion product transport and cycle chemistry variances on the efficient operation of heat recovery systems. With a wide variety of cost effective technologies and pre-engineered systems, Graver can provide cost effective solutions for both new and existing plants, whether base load or peaking plants, for the optimum protection of a plant’s valuable assets.

All products are marketed by the Graver Water and Graver Technologies units of Marmon Water a segment of the Chicago based Marmon Group, a Berkshire Hathaway company. Graver has engineering & manufacturing locations in NJ, NY & DE with sales offices throughout North America, Europe and China. Graver’s products & technologies are also available globally through a network of authorized Graver licensees.
