How does a blowdown tank work?

Purpose: The blowdown tank is designed to prevent high pressure steam and water from entering into drains and possibly scalding someone. Therefore, it is provided with a chamber that will allow the blowdown water to cool before discharging and allow the steam flashed from the blowdown water to vent to atmosphere.Click to see full answer. Regarding this, how does a blowdown valve work?The main function of blowdown valve is mainly to control a continuous flow of steam /fluid under high differential pressure. The outstanding feature of this type of valve is that it can maintain fluid tightness and it is easily operated without the help of any wedging action.Furthermore, what is the purpose of a blowdown separator? A boiler blowdown separator is designed to take water from the boiler during blowdown and reduce it to atmospheric pressure for disposal. As the blowdown enters the vessel, it is forced into a centrifugal pattern by means of a striking plate. The steam is vented to the atmosphere through a top connection. Subsequently, question is, what is blowdown process? From Wikipedia, the free encyclopedia. Boiler blowdown is water intentionally wasted from a boiler to avoid concentration of impurities during continuing evaporation of steam. The water is blown out of the boiler with some force by steam pressure within the boiler.What is blowdown pressure?Blowdown. Blowdown is the difference between the set pressure and the reseating pressure of a safety or relief valve, expressed as a percentage of a set pressure or pounds per square inch.
