Thank you for sharing this information. I deal with small low pressure electric steam generators and it can be difficult to control the mineral buildup and steam purity in these systems. I'm in east Texas and we have a diversity of water types that make it even more interesting! Thanks again, I definitely learned some things.
excellent webinar, thanks
Thanks
great learning, excellent details and coverage of topic.
We are glad to hear that this information was very helpful.
Excellent
Sorry, what is blowdown?
Blowdown is discharge of water from an evaporative heating or cooling water system such as steam boiler or cooling tower system. Blowdown helps prevent problem-causing impurities in the system water from over-concentrating by replacing a portion of the system water with unconcentrated makeup water. Blowdown can be intentional or unintentional. Bleed is the term usually associated with evaporative cooling systems, while blowdown is the term usually associated with steam boilers. The terms are used interchangeably. You can reach more in our blog The Value of Good Boiler Blowdown (www.chemaqua.com/en-us/Blogs/the-value-of-good-boiler-blowdown-control) and All About Cooling Tower Makeup and Blowdown (www.chemaqua.com/en-us/Blogs/all-about-cooling-tower-makeup-and-blowdown)
Blowdown is kind a process for purifying the water because "real" water is not pure - it has some stuff ( solids) which will not be dissolved in the process and it will remain as solids which will cause corrosion and other damages in piping which will decrease boiler efficiency. So this harmfull solids must have to be removed out of the boiler.
As water evaporates or turns to steam, it leaves behind the impurities like calcium, etc.
You then introduce new fresh water to replace the qater that left and did not return through loss.
Eventually, as you can imagine, after many cycles, you will have a large concentration of those.impurities in the boiler water.
Blow down is the process of removing some over concentrated water that has all those dissolved solids built up, and replacing it with equal parts make up water (new water that is being introduced to the system for the first time)
This helps to reduce scale, corrosion, etc.
