Flash Vessels Type VD Flash Vessels Systems Type VD 23 and VD 26 Condensate from H .P . user 142 Drain Water Condensate Flash Vessel Flash steam <strong>Technical</strong> Data Type Flash steam outlet Application downstream of a pressure-relief valve Gas balance pipe to condensate tank Pressure relief valve Hot water Boiler Service pressure [bar] Application Condensate flash vessel Condensate flash vessels can be used in all steam plants where condensate from steam processors is reduced to a lower pressure, so that flash steam is formed by revaporization . In the flash vessel the steam is separated from the water, and then fed into a lowpressure steam system . The condensate remaining in the flash vessel is discharged into a condensate tank . Blowdown flash vessel Blowdown flash vessels are used if the flash steam formed downstream of continuous blowdown valves is to be utilized . Blowdown flash-vessel system Steam boiler from feedwater tank Service temperature [°C] Feedwater-tank with deaerator Live steam supply Continuous blowdown valve Intermittent blowdown valve Blowdown flash vessel Condensate flowrate [t/h] Blowdown receiver Blowdown receiver In a blowdown receiver the sludge and water mixture withdrawn from the boiler by the intermittent blowdown valve is separated into flash steam and condensate (residual blowdown) . Pressure-relief valve When pressure-relief valves of hot water boilers blow off, flash steam is formed which is discharged to atmosphere by a blow-off line . For reasons of safety, to avoid scalding of personnel and damage to equipment by hot water discharged through the blow-off line, a flash vessel is installed between pressure-relief valve and blow-off line where steam and water are separated . Pulse from intermittent blowdown valve Volume [l] VD 0 .5 – 13 111 – 250 1 .2 – 40 50 – 1400 Cooling water Laugenkühler Material (DIN reference) S235JRG2 (RSt 37-2) / P265GH (HII) VD 23-0.3 13 200 0 .3 15 S235JRG2 (RSt 37-2) / GG 25 VD 23-1.0 13 200 1 .0 15 VD 26-0.2 32 250 0 .2 15 P265GH (H II) / GS-C 25 VD 26-0.7 32 250 0 .7 15
Blowdown Receiver (Mixing Cooler) VDM <strong>Technical</strong> Data Hot water from intermittent/ continuous blowdown, overflow etc . Drain Mixed cooled water to drain Flash steam discharge or vent Thermostat Max. service pressure Max. temperature Capacity range Material 0 .5 bar 111°C up to 15 t/h S235JRG2 (RSt 37-2) P265GH (H II) 1 .4541 1 .4541 Cooling water Mixing cooler with cooling-water control and, if requested, additional flash-steam condensation Description Mixing coolers are blowdown receivers used to cool hot waste water that can no longer be used for heat recovery and is therefore discharged into a pit or drain . Application Process plants where contaminated, hot waste water is being formed . Steam boiler plants where the blowdown is cooled with untreated water . Mixing coolers for vapours . 143 C
