Boiler Carryover – Cause, Effect and Prevention |

Mechanisms. Carryover also known as priming is any solid, liquid or vaporous contaminant that leaves a boiler with the steam. In low/medium pressure boilers (<100 bar) entrained boiler water is the most common cause of steam contamination. Both mechanical factors such as boiler design, high water levels, load characteristics and chemical factors such as high solids concentration, excessive

Auxiliary Boiler - an overview | ScienceDirect Topics

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
