EMISSIONS CONTROL: The importance of perforated-plate design in simple-cycle SCR systems

By Vaughn Watson, Vector Systems Inc The performance of an SCR system depends on the robustness and efficiency of the sum of its parts. The flow-distribution devices placed into the exhaust stream are no exception. Each of the critical parts of the system must be designed and built to effectively provide the proper distribution and […]

GROOME BOOM: Clean HRSG tubes save fuel, improve plant’s bottom line

The headline should not surprise any reader of the COMBINED CYCLE Journal. It’s a “given.” The challenge is how to maximize the saving at the least cost. Until relatively recently, the widely preferred method for cleaning tubes in heat-recovery steam generators serving cogeneration and combined-cycle plants was dry-ice blasting. It effectively dislodges iron oxides, ammonia

SCR SYSTEM PERFORMANCE: Ammonia-system maintenance considerations

By Vaughn Watson, Vector Systems Inc The long-term performance of an SCR system depends on the efficiency of its critical components (Fig 1). While the catalyst often gets all the credit, and all the blame when performance declines, proper maintenance and routine inspection of the ammonia system can alleviate and prevent many factors that contribute

HRSG maintenance: normal, major, preventive

Sponsored content from Bremco, an SVI Industrial company. The complex steam/water circuitry of heat-recovery steam generators, especially that in the multi-pressure HRSGs typically used in large-power applications, often requires special considerations when scheduling and performing maintenance and repairs. Many combined cycles go through multiple load changes daily—including on/off operation—which put intense thermal, mechanical, and water-chemistry
