There are several reasons stacks don’t get much attention from operators on their rounds—among them: They’re static and there’s nothing much to see externally except perhaps peeling paint. Forgetting the switchyard, they’re likely a longer walk from the control room base than any other plant component. Internal access is not possible with the plant in

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

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
