During the operation of the boiler the boiler water was analyzed for alkalinity and electrical conductivity. The alkalinity of boiler water for phenolphthalein (A ph) is 20 mg-eq/l for methyl orange (A mo) is 2.0 mg-eq/l. Total alkalinity is 22.0 mg-eq/l. The boiler water conductivity 7798 S/cm.Get price
SiO 2 0.2 to 0.5 kcal·m 2 ·h 1 per degree C. This scaling is mainly caused by the presence of calcium salts (carbonates or sulphates) in the water. These salts are less soluble when hot than when cold or when there is an excessively high level of silica in relation to the alkalinity of the water in the boiler.Get price
Apr 29 2020 · Inherent alkalinity helps maintain feed water alkalinity within parameters of 8.6 to 9.0. Used in boiler operating above 32 bar will not readily react with O 2 below 50 o C hence risk of copper corrosion occurs with the ammonia stripping off the continuously reforming copper oxides. Supplied as a 35% solution Carbohydrazide (N 2 H 3) 2 COGet price
Alkalinity Of Boiler Water - nederlandsenoodhulpclan.nl. Boiler Water Sample OH-Alkalinity: This is a calculation only. OH-Alkalinity = (2 x P-Alkalinity) M-Alkalinity Record this value. There is no specific limit for OH-Alkalinity but this value should be relatively consistent over time if the boiler water control is properly maintained.Get price
