Abstract. This report broadens a previous review of published literature on corrosion of recovery boiler superheater tube materials to consider the performance of candidate materials at temperatures near the deposit melting temperature in advanced boilers firing coal, wood-based fuels, and waste materials as well as in gas turbine environments.
Get a QuoteBased on a distributed model for heat transfer of superheater,a simulation research on the wall temperature distribution characteristics is performed for the rear platen superheater and high-temperature superheater.The simulation results show that there are obvious

Since, the both SFCs (FY-03A and FY-03B) were not designed for dynamic compensation, so that they are not effective when the boiler load changes
Get a QuoteSuperheaters Coils are the most critical Boiler Component of the modern day Thermal Power Plant and are subject to very high metal temperatures. In fact the capacity of the Superheater to work without failure at higher Temperatures is what determines the boilers Capacity and it effects improvement in economy by reducing Steam Consumption of the
