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.

Scaling in boilers - Lenntech

Causes, and prevention of scaling in boilers, type of scaling. Boiler scale is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent. Evaporation in a boiler causes impurities to concentrate. This interferes with heat transfers and may cause hot spots.

2011-1-22·pH measurement The pH value is a measure of the alkalinity or acidity of an aqueous solution. The scale reaches from 0 (highly acid) to 14 (highly alkaline). On the basis of this scale, liquids are referred to as acidic (e.g. hydrochlo-ric acid), neutral (e.g. distilled water) and alkaline (e.g. sodium hydroxide). The pH value can be measured by

Alkalinity - Whitman College

2012-6-13·To determine the alkalinity, a known volume of water sample is titrated with a standard solution of strong acid to a pH value in the approximate range of 4 to 5. Titrations can distinguish between three types of alkalinity; carbonate, bicarbonate, and total alkalinity. Carbonate alkalinity is determined by titration of the water sample to the
