Explain the role of Eriochrome Black T and ammonia buffer

4. What are the disadvantages of using hard water in boiler? (Nov. 2010) Water used for steam generation should be free from hardness, otherwise it will cause boiler problems like scale and sludge formation, priming and foaming, boiler corrosion, etc. Hence, water is softened before feeding it to boiler…

Proper sizing of Boiler Feedwater System

One boiler horsepower = 34.5 lbs/hr of steam (or water) from and at 212o F. We also know that one-gallon of water weighs 8.37 lbs. To calculate the storage tank needed use the following formula: BHP X 34.5 ÷ 8.337 lbs ÷ 60 min. X 10 = minimum useable capacity in gallons. For example, if you have a 500 HP boiler the calculation …

Steam Calculators: Boiler Calculator

Mar 17, 2015 · Feedwater Mass Flow = Steam Mass Flow / [ 1 - Blowdown Rate ] Using the Steam Property Calculator, properties are determined using Deaerator Pressure and Quality = 0 (Saturated Liquid). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Feedwater Energy Flow = Specific Enthalpy * Mass Flow.

What is Caustic Corrosion? - Definition from Corrosionpedia

Oct 08, 2016 · The water then diffuses out of the cracks, leaving behind hydroxide salts that accumulate when more water evaporates. These remained salts of sodium hydroxide or caustic soda react and dissolve the protective magnetite layer (Fe 3 O 4), eventually causing further metal loss from inside the boiler shell and finally equipment failure.
