Mixing Cooler

About Mixing Cooler

Intermittent and continuous blowdown of boiler water is discharged into a combined collection and cooling vessel before disposing it to drain.  GESTRA’s blowdown vessel (mixing cooler) reliably copes with high temperatures, pressures, and effects of erosion, sludge, and precipitated solids to safely discharge flows under permissible temperature limits.

Description

Intermittent and continuous blowdown of boiler water is discharged into a combined collection and cooling vessel before disposing it to drain.  GESTRA’s blowdown vessel (mixing cooler) reliably copes with high temperatures, pressures, and effects of erosion, sludge, and precipitated solids to safely discharge flows under permissible temperature limits.

Mixing coolers (a type of blowdown receiver) cool hot effluent that can no longer be used for heat recovery and must therefore be conveyed into bodies of water, pits, or sewers. Typical applications for mixing coolers are, for example:
• Production systems in which hot, contaminated effluent is produced
• Steam plants in which intermittent or continuous blowdown has to be cooled with raw water
• Use as a blowdown receiver for flash steam

The hot waste water is discharged into the mixing cooler, which is at atmospheric pressure, and passes over the rod feeler of the thermostat. The cooling water enters via a solenoid valve, the amount depending on the temperature setting of the thermostat. Flash steam is formed if the waste water is discharged from the system under pressure with a temperature above 100 °C, as is the case for intermittent boiler blowdown. If the flash steam can neither be recovered nor discharged to the atmosphere (because of the inconvenience caused by the condensing steam), the flash steam can be condensed inside the mixing cooler. This is performed by a second cooling water spray nozzle
