Recover Heat from Boiler Blowdown Water

2012-5-31 · The blowdown water heat recovery system generates flash steam due to a difference in enthalpy (total heat content of steam) at higher (blowdown) pressure and lower (flash) steam pressure. Amount of flash steam is calculated by using following equation. Where = Enthalpy or heat content of blowdown water at boiler pressure

Operation of Boiler and Conductivity in Drum Water

Water chemistry sensors for both feed water and boiler need monitoring as any impurities in this gets concentrated and gets carried over in the steam. Conductivity controls for water blowdown in the drum type boiler are a method to remove such concentrate. Conductivity is just one of many factors to monitor. Changes in conductivity readings in various area gives a good clue to operators to

Corrosionpedia - What is the Rate of Blowdown

The rate of blowdown is the intentional periodic removal of water from the cooling tower, boiler or any other heat exchangers. The primary purpose of blowdown is to maintain the solids content of boiler water within certain limits. For boiler water, a high blowdown rate is required to eliminate the contaminants as rapidly as possible.
