blowdown – Water Technology Report

20/6/2016 · Blowdown rate is expressed as a percent of total feedwater demand. Thus, a 5% blowdown rate means that 5% of the boiler feedwater is lost through blowdown and the remaining 95% is converted to steam. The blowdown rate (expressed as a decimal) is calculated as the reciprocal of the number of times the feedwater is concentrated in the boiler.

What is the Rate of Blowdown? - Definition from Corrosionpedia

15/8/2017 · 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.
