• As this system itself acts as bypass system for turbine, no bypass is required for this system again. • If condensers are equipped with safety devices like rupture discs then no extra safety devices like safety valves are necessary.
• Protection of Condenser against excessive Pressure & Temperature. • Partial Bypass to maintain steady upstream pressure when Turbine runs back to house load. • Efficient matching of steam & turbine metal temperatures during cold, warm & hot start up cycles. • To prevent boiler pressure fluctuations in case of Turbine trip or load rejection. • To avoid the lifting of HP safety relief valve & condensate loss. • Cooling of final superheating in case of falling pressure application. • Controlled pressure build up during start up operation or in the event of Turbine Trip.
• Angle type Combined PRDS valves with various stages on pressure and temperature reduction. • Customized designs to accommodate complete performance needs. • Tailor made multi stage Trims for Dynamic noise control. • Cast / Forged body selection available. • End connections to meet existing piping sizes & materials. • Bolted Bonnets for easy serviceability. • Trim removable thru’ bonnet, In Line. • Installation in any orientation. • Shut off in accordance with ANSI / FCI 70.2, Class V. • Dump Tubes can be designed & supplied on request • Suitable for Feedforward as well as conventional control strategies.
