Blowoff Tanks

Penn Blowoff tanks come standard ASME Code Sec. VIII, Div.1 designed and stamped for 50 psig at 450 deg. F. and are of a welded construction from 3/8" thick carbon steel materials. A blowdown tangential inlet with stainless steel wear plate, water overflow outlet which extends to within 6" of the bottom of the tank, a 3/4" siphon shall be located in the top portion of the outlet pipe and atmospheric steam vent. The tank would be supported by a set of four angle legs with floor pads. 36" diameter and smaller tanks include couplings for inspection ports and larger tanks include a manway. A level gauge, thermometer, and pressure gauge can also be supplied as an option.

The blowdown from a boiler(s) that enters a sanitary sewer or discharges in an area which could be hazardous to life or property should be controlled. The control should be through some form of blowoff equipment which will reduce the pressure and temperature to acceptable safe levels.
