Blowdown is the process of pulling off of the bottom of a vessel like a drum to remove contaminants. Blowdown is also a method of reducing or controlling level in a vessel such as drum level. These blowdowns could be to a contained system or to sewer and can be continous or intermittent. Blowdown Header collects blowdown fluids from all source and transport it to the related handling, treatment or disposal system.
Boiler blowdown is required to prevent corrosion by removing impurities that contribute to its formation in a steam boiler and to facilitate the generation of pure steam by preventing the carryover of impurities. Why Boiler Blowdown is Required? Proper blowdown procedures are necessary to maintain the solids content of the boiler water within specific limits and to quickly eliminate contaminants if the water becomes contaminated.
The function of the adjusting ring is to adjust the blowdown pressure of the safety valve. By ASME rules this must be adjusted to 2% of the set pressure, or a minimum of 2 psi. If the valve is set to lift at 100 psig or less then the blowdown must be set at 2 psi. If higher then it must be set at 2%. Thus, for a safety valve that lifts at 300 psig, the blowdown will be set (at 2%) such that the valve will reseat when the pressure drops to 294 psig. In many states that have adopted ASME rules, these settings cannot be changed except by an authorized safety valve repair shop holding a National Board repair or assembly "V" or "VR" stamp.
"Boeren" ("Peasants"), "Red White Army" and "Rood-witten" ("Red-whites") are nicknames for PSV Eindhoven.
