Auxiliary Boiler - an overview | ScienceDirect Topi

Common auxiliary steam pressure control: Here the steam header pressure is measured in one of two modes and compared with a fixed set point. The deviation this creates is used to drive a PI controller. The output of the controller, through two sets of A/M stations and I/P converters, can regulate the pressure-reducing valves in MS and CRH lines to maintain constant pressure at the common
