Computer modeling of a convective steam superheater
Computer modelling of a convective steam superheater 127 hand – from the fouling of heating surfaces by slag and ash [6–9]. Slag and ash deposition processes are hard to evaluate, at the design phase as well as during the boiler operation. For that reason, the

How to Destroy a Boiler -- Part 2 - NBBI
Conversely, operating the steam generator continuously above MCR may cause long-term maintenance problems resulting in associated costs that are not easily detectable during the short term. In situations where the production demand warrants overfiring the steam generating equipment, it may be a good business decision to suffer the short- and long-term increased …
