STEAM SEPARATORS

Size Range: 1,000 lbs/hr to 50,000lbs/hr nominal steam rate

These horizontal steam separators were designed specifically for use with Maxim heat recovery equipment and usage on reciprocating engines and gas turbines.

Functions

• Separates liquid and vapor entering the HSS• Serves as a liquid reservoir and liquid level control point for the system• Serves as a trap and blow down point for sludge and other contaminants circulated in the system• Mounts safety valves, level alarm switches, pressure gauges and other devices for protection of the system

First stage separation is accomplished by an impact plate which provides constant steam quality regardless of water velocity and allows major nozzles to be located on the centerline of the vessel. Additional baffling and surface control plates minimize frothing and liquid carryover. Standard configurations give a minimum steam quality of 98%. With optional mesh type mist eliminators, solids carry over is limited to 1 part per million from liquid concentrations as high as 2,000 parts per million.

Standard Trim Components

• Liquid level controller• Safety valve• Visual liquid level gauge• Surface blow-off valve• Automatic air venting• Liquid drain valve• Pressure indicator• High liquid level indicator• Low liquid level indicator
