Lecture 11 | Boiler | Chemical Process Engineering

2017-2-17 · Water Treatment and Chemic. als for Boiler Water Systems Types of Boilers A boiler is used to heat water and generate required ste am or hot water. There are various types of boilers according to their uses structures, the methods of water circulation, the types of fuels, and the kinds of the materials used. In general, they are roughly classified into cylindrical bo ilers and water-tube boilers.

Water Handbook - Ion Exchange & Water

2021-1-2 · Ion exchange uses are not limited to process and boiler water makeup. Ion exchange can be used to purify, or polish, returned condensate, removing corrosion products that could cause harmful deposits in boilers. Typically, the contaminants in the condensate system are particulate iron and copper.

Understand the importance of water/steam chemistry

Like feed-water chemistry, boiler water chemistry has undergone a considerable evolution over the past two to three decades. For decades, phosphate programs have been the workhorse of many treatment programs. Tri-sodium phosphate provides alkalinity beyond that of ammonia. Na 3 PO 4 + H 2 O → NaOH + NaH 2 PO 4

Ion Exchange. Ion exchange is just what it implies: a process that exchanges one type of ion (charged particle) for another. Many troublesome impurities in supply water are ions, making this process extremely important in boiler water treatment. Ion exchange takes place in a closed vessel which is partially filled with an ion exchange resin.
