WebASME blowdown tanks for boilers are used as an alternative system for cooling the bottom boiler blowdown. These large tanks retain the blowdown water volume from one blow after the flash steam has been vented to the atmosphere and allow the water to cool down by natural convection over a 6-12 hour period. WebThe selection of a blowdown vessel depends on the flowrate and the proportion of flash steam released. The following factors affect the selection: The blowdown line size. The length of blowdown line between the boiler and the blowdown vessel. For example the sizing below assumes the blowdown line has an 'equivalent straight length' of at least 7 m.
