Desludging<\/strong> is the term used to describe the Draining the boiler water incl. of the impurities,<\/strong> that have settled on the bottom of the boiler<\/strong>. Contamination<\/strong> occurs due to the introduction of the fresh water<\/strong> and return condensate<\/strong>. However, even during steam generation<\/strong>, the concentration of impurities<\/strong> in the boiler increases during the evaporation process<\/strong>. The plant control system<\/strong> monitors the boiler water<\/strong> and initiates the necessary blowdown<\/strong> process<\/strong>once or twice a day<\/strong> for approx. two seconds via the blowdown valve.<\/p>\n The 100 \u00b0C hot blowdown water<\/strong> is fed<\/strong> into the blowdown tensioner and collected there. To avoid damage<\/strong> from heat in the pipe system<\/strong>, the blowdown water<\/strong> must be cooled<\/strong> down before it can be safely discharged into the sewer system<\/strong>. For this purpose, the water temperature<\/strong> is measured in the tank<\/strong> with the help of thermostats<\/strong>. According to the preset values<\/strong>, a solenoid valve<\/strong> regulates the fresh water supply for cooling to approx. 35 \u00b0C<\/strong>. The flash steam produced in<\/strong> the flash tank by the fresh water supply is led outdoors<\/strong> through a vent pipe<\/strong> via the roof. The cooled<\/strong> blowdown water<\/strong> flows through the pipe into the sewer system<\/strong>.<\/p>\n This is how a blowdown tank or also<\/strong> called blowdown tank, blowdown cooler or mixing cooler works. No matter what you call it, our experts in<\/strong> the tank construction department<\/strong> have over 20 years of experience<\/strong> in tank construction<\/strong> and will take care of the correct design<\/strong>. We manufacture these not only for our own steam boiler plants<\/strong>. We sell standard designs from stock<\/strong> via our webshop<\/strong>. Of course, we also produce special sizes<\/strong> upon request.<\/p>\n
