CHAPTER 1 - STEAMC. Boiler Feed and Vacuum PumpsControl & Pipe (same as Boiler Feed & Condensate Pump)Additional Piping: Equalizing line between boiler steam header andvacuum pump. Equalizing line will prevent a possible vacuum developingin steam supply that could be greater than vacuum in the return.32
CHAPTER 1 - STEAMSizing of Vacuum PumpVacuum condensate pumps are normally sized at 2 or 3 times the systemcondensing rate. This is the same procedure for sizing standardcondensing rate. The vacuum pump must also remove air from thereturn system. The system size, the inches of vacuum desired, andtightness of the system piping must be considered. The following chart.will help.1 210Air Removal RequirementSystem Vac / In. Hg.
