Performance Analysis of 210 Mw at NTPC Vindhyachal, Singrauli

WebThe graph represents the relation between HRH steam temp. before LPBP and mid-wall temp. of IPS. It ensures that the inlet HRH steam temp. must be higher than the IPS temp. It is usually useful for warm and hot start-up. Criteria for slow and normal mode is identical. f CRITERIA – X5 Slow Mode Normal Mode Fast Mode WebIt has the ability to prevent overpressurization of the steam source by popping up a safety valve to release excess steam. • During start-up, shutdown, and large load throw off, the HRH steam bypasses the IPT and LPT and goes to the condenser after pressure and temperature reduction with the help of the LP bypass (LPBP) system, as applicable. • mentee goal setting template

WebLiberation of cobalt-based hardfacing (oft-used Stellite™ being one of these materials) from large Grade 91 valves installed in combined-cycle main and hot-reheat (HRH) steam systems, and in steam turbines, was a hot topic in the industry about a decade ago. WebIt is named an attemperator because it tempers the high steam temperature to an accurate temperature. Functionally, a desuperheater and attemperator are the same, i.e. they … WebSteam blowing is one of the initial cleaning operations before starting any power plant or steam lines.
