Steam Separators

Penn Separator

Blowdown Separators

Intermittent Boiler Blowoff, Hydronic S.R.V’s, and other Process Blowdown

PROVEN PERFORMANCE The modern and efficient way of handling boiler intermittent blowdown. Separators have also been used for hydronic safety relief valve discharges, deaerator overflows, autoclave draining, and other high flow pressurized condensate to drain applications. The smaller diameter takes up less space then a traditional blowoff tank while providing an efficient separation of flash steam and condensate.

PROVEN DESIGN FEATURES Penn has been a leading supplier of Blow-down Separators for over forty years. This experience goes into every separator we build. Standard features like stainless steel internals and self drying design assure years of trouble free service.

CYCLONE SPINNING ACTION The tangential entry and small diameter creates a cyclone action to efficiently separate steam and condensate. The clean steam flows up through the vortex to the vent discharging quitely to atmosphere.

CONTROLS THERMAL POLLUTION Most Separators come packaged as shown with accessories for automatic cooling of condensate to drain which meets local sewer temperature requirements. The package shown includes a A34B Separator with A100L Angle Legs, A18DF Aftercooler, Self Actuating Temperature Regulator Valve, Strainer and Bimetal Thermometer. Other package options are available.

Flash Separators

Flash Tanks for Handling Condensate and Flash Steam Recovery

Penn Flash Separators use a tangential inlet and cyclonic action to instantly separate steam and condensate. Our Flash separators are smaller in size and more efficient then traditional flash tanks. Because of the unique smaller size they are less expensive then traditional flash tanks. The clean steam can be returned to a lower pressure saving valuable BTU’s and makeup water. Return on investment can be in a matter of weeks. Easy to use flash steam and selector charts assure proper sizing of a Flash Separator for your condensate requirements. Special tank designs are also available. Penn Separator has over forty years of experience building pressure vessels to ASME Code. All Penn Flash Separators are constructed to the ASME Code Sec. VIII.

  • SMALLER SIZE. Replaces Larger Flash Tanks
  • SAVES MONEY. Returns Valuable BTU’s in Flash Seam
  • PRE-ENGINEERED DESIGN. Convenient Charts for Easy Selection
  • QUALITY CONSTRUCTION. Built to the ASME Code Sec. VIII. Div. 1

Exhaust Silencers

When steam air and other gases are vented to atmosphere at high velocities noise is created. Typically the higher the velocity the louder the noise level. Penn makes two models of exhaust silencers to reduce noise levels.

The SP Silencer The SP Exhaust Silencer is a single pass silencer designed to give maximum attenuation of both low and high frequency noise for air, steam, or gas exhausting to atmosphere.

The SP-S Silencer The SP-S Exhaust Silencer is an economical approach to silencing where the noise level reduction does not have to be as great as the SP model. The SP-S Silencer has the same physical configurations as the SP Silencer except that it is two-thirds the length of an SP Silencer.

The gas enters the inlet of the silencer where the flow is disbursed through the inlet diffuser tube into hundreds of small jet flows. This provides for quite flow of the gas into the silencer and the first stage silencing chamber. The diffuser also directs the flow toward the outer walls of the silencer body. The gas then repeats the same process contracting and expanding into the second stage chamber. The second chamber reacts with the noise the same way as the first chamber dissipating and absorbing the noise that is left over. The second chamber also has an important function as a reflow area. It allows for an even flow of gas to the outlet. This assures the quiet release of gases to the atmosphere trough an adequately sized outlet.

Each silencer reduces noise differently. The larger the size, the higher the reduction. These reductions range from 24 to 46dB (A) depending on the model. The following page gives these combined reductions as well as sizing information, and suggested specificaions, and dimensions.

The SP and SP-S Exhaust Silencers have the same quality of workmanship that has gone into all Penn Products
for so many years and is guaranteed for a year against defects in materials or workmanship.
