Steam Tip 23: Automatic Blowdown-Control System | Campbell

Steam Tip 23: Automatic Blowdown-Control System. To reduce the levels of suspended and total dissolved solids in a boiler, water is periodically discharged or blown down. High dissolved solids concentrations can lead to foaming and carryover of boiler water into the steam. This could lead to water hammer, which may damage piping, steam traps
