There is a large amount of heat energy in the condensate that is discharged into the drain or released into the atmosphere as flash steam. Likewise, blowdown lines containing high temperature unusable water are a recyclable source of heat energy. VCH-3, VCH-5 and VCH-8 are atmospheric and indirect heat exchangers that recover waste water (blowdown water) or flash steam as hot water that can be used in many different applications. The hot water produced by the VCH series is suitable for production processes, post-production cleaning applications, heating and many other applications. VCH Series waste heat recovery units do not require an additional heat exchanger and operate at atmospheric pressure. It provides energy recovery in steam boiler blowdown, flash steam applications, condensate tank breather and autoclave applications.
Flash Steam Heat Recovery
When steam encounters a cooler surface, it loses some of its heat. This heat loss experienced by the steam causes the formation of small water droplets that occur with the condensation of the steam called condensate. Increasing the feedwater temperature of the steam boiler every 6 ° C can provide an energy saving of approximately 1%. Therefore, the recovery of condensate as hot water is of great importance in terms of energy saving. Flash steam that occurs on the suction side of electric pumps at high condensate temperatures will cause cavitation, so condensate pumps are used unlike ordinary pumps. Vira Condensate Pump does not contain mechanical parts that can be damaged. Level control is carried out electrically by means of electrodes, not with floats. If desired, it can be supplied as a system with globe valve, strainer, solenoid valves and check valves or just as the condensate pump itself and the level measurement system.
