Inexplicable pH drop in boiler blowdown water

Inexplicable pH drop in boiler blowdown water. A discussion started in 2004 but continuing through 2019. 2004. Q. This question pertains to drop in pH of blowdown water of a low pressure steam boiler. In one of the waste heat recovery boilers, (operates at 180 °C), pH of the blow down water drops to 5 and even 4.

What is the reason for keeping a boiler feed water pH

Chemical reactions happen very fast at elevated temperatures. Because of this we try to operate the boiler at the lowest possible corrosivity relative to pH (Note: this is only for boiler operating without high purity feedwater). That point is aro

pH Treatment. Introduction. A pH less than 7 is acidic, and a pH greater than 7 is basic (alkaline). Each whole pH value below 7 is ten times more acidic than the next higher value. For example, a pH of 4 is ten times more acidic than a pH of 5 and 100 times (10 times 10) more acidic than a pH of 6. Boiler Efficiency; Steam Basics;
