Regular boiler water tests are crucial to ensure that the entire steam system is protected and fully functioning. When possible, the water treater should be testing the make-up water, the softener and/or RO pretreatment systems, the deaerator, the feedwater, the boiler water and the condensate systems. Boiler water tests are based on the program selected by the chemist.

Caused by the presence of calcium and magnesium. Hard water consumes soap before a lather will form and creates scale in boilers, water heaters, and pipes. 0 - 60 mg/L soft 61-120 mg/L moderate 121-180 mg/L hard >181 mg/L very hard Water Softener Calcium and Magnesium
intercrystal1ine cracking of the boiler metal. 1.3 Tests In control of water treatment, certain tests or water analyses are necessary. The specific test procedures are described in Section 8. The significance, meaning, and purpose of the tests in reference to water treatment are discussed briefly below.
Jun 09, 2017 · hydrazine test: this test is carried out to find out reserve hydrazine in boiler water which is an oxygen scavenger. reserve should be between 0.1-1 ppm. test procedure:-a)take 250 ml of cooler boiler water sample, 15 ml of n/2 hcl and 2 nesslers cylinders. b) in 1st cylinder add 25 ml sample and then add 4-dimethylaminobenzaldehyde.
BOILER WATER P Alkalinity Range : 50 2400mg/l (as CaCO 3) Take sample according to expected range. (See table below) Add drops of KS135 PA1/ALK1 colourless (Phenolphthalein Indicator) to give a Pink colour. If sample remains, report the P Alkalinity as zero. Count drops of: KS139 - TA3 or KS136 - PA2/TA2 until colourless.

Boiler firing problems and/or non-ideal fuel characteristics can result in increased emissions. Accordingly, inspections should involve an evaluation of fuel quality and the exterior integrity of boiler.
