Wright-Austin exhaust heads are used at the end of pipelines to reduce droplets and particulates exhausted to the atmosphere. A common application for exhaust heads are at the end of condensate vents to reduce the visible condensate plume. In climates where freezing occurs, installation of exhaust heads reduces the hazards of dealing with ice accumulation on the roof. The advantages of installing Wright-Austin exhaust heads go beyond appearance, some of our customers recover expensive boiler chemicals that would otherwise be carried-off with the water droplets; there may be environmental factors associated with discharge of certain compounds.
Wright-Austin exhaust heads provide an inexpensive and non-mechanical method for removing 99% of all entrained moisture and particulates from the gas flow > 10 microns in size. There's no maintenance or other service required. The recovered fluid can be plumbed for reclamation/recycling or, if applicable, sent to drain.
Cast iron exhaust heads are typically in-stock and are for pipelines from 1" to 10" in size. Fabricated exhaust heads can be manufactured for any size pipeline; our website provides pricing and outline drawings for separators as large as 24", although we've fabricated them for pipelines up to 42" (a refinery application). An ASME Code Stamp and CRN are not applicable to exhaust heads because one end is opened to atmospheric pressure, thus they are not pressure vessels.
Fabricated exhaust heads, typically made from carbon steel and stainless steel can offer some advantages because we can size the exhaust head body to maintain performance/efficiency but provide a reduced flanged connection to match your existing pipe size which may help reduce overall costs.
