Coal Boiler Outlet Temperature

Outlet Temperature - an overview | ScienceDirect Topics

HRH boiler outlet temperature measurement is an important parameter so one of two redundancy is generally utilized in utility plants. For two outlet headers this is to be repeated for both sides. • For LP bypass, generally the control is with the turbine manufacturer/supplier, so while specifying the system-required redundancy at least one of two redundancy may be selected for pressure as
