Water chemistry is known to be a key factor in determining the risk of FAC; it can be modified if required during operation to potentially affect wear rates. Another key factor, determined at the design stage, is the chrome content of the steel.Grade 91 Steel - How Did We Get Here? Part 1 BechtJan 10, 2019This blog is the first part of a 3-blog series.

Unfortunately, a large number of these plants are minimally staffed, often with few, if any, employees that have a strong background in water and steam chemistry.
In particular, Grade 91 materials were viewed by the booming combined-cycle power plant industry as a panacea for the thermal fatigue that plagued large HRSGs operating in cycling duty.

Jul 20, 20205. You mentioned a pH range of 8.0-8.5 for OT systems. Is there a problem with running at a slightly higher pH, say around 9? No. The OT programs can run at lower pH, but there's no concern with operating at higher pH. We have experience with some plants using OT that operate with a feedwater pH in the 9.6-10.0 range.Tracy Peaker Plant : Performance MechanicalPMI performed BOP and electrical for the 315 MW GWF Tracy combined cycle power plant.

Welding chrome-moly tube and pipe conventionally is done with shielded metal arc welding (SMAW) or submerged arc welding (SAW). Flux-cored arc welding (FCAW) has been tried, but the wires had some drawbacks that prevented widespread acceptance. Recent developments have reduced some of these disadvantages, so GMAW deserves a fresh look. The switch might lead to improvements in the weld's Handling Nine Chrome Steel in HRSGs Power Engineeringdiagram of babcock wilcox boiler in power plant Steam Handling Nine Chrome Steel in HRSGs Power Engineeringh. mqore. jr 3,561,216 . thermal stress controlled loading 0f steam turbine-generators filed march 19, 1969 4 sheets-sheet his attorney.Handling Nine-Chrome Steel in HRSGs Power Steam-Plant Industry Wrestles with Increased Use of P91/T91 and Other welding stainless steel tubes for nuclear power generation wHandling Nine-Chrome Steel in HRSGs Power Engineering 2/1/2006 In a fossil boiler's superheater and reheater tubes, in contrast, hot furnace gas is the source of heat, and thermal energy flows in the opposite direction from the tube"s outside wall toward Handling Nine Chrome Steel in HRSGs Power Engineering
