Introduction:

Boiler is a vessel wherein water is heated to convert into steam, with the application of heat of a burning fuel and/or the hot exhaust gas from some process. Continuous supply of pure water is one of the essential requirements for steam generation.

Water is abundantly available, but the problem is, pure water simply does not exist in nature.

Natural Water specifically contains suspended solids, dissolved solids and dissolved gases. These impurities reduce efficiency and damage plant equipment.The goal of boiler water treatment is the prevention of water related problems in steam generating systems and associated equipment. Those problems include corrosion, scale formation and carry -over. Depending upon the working pressure and temperature of boiler, the quality of Feed Water for the boiler is to be maintained.

Role of an O&M Engineer:

Quite often it is seen that the water chemistry control responsibilities lie with the DM plant personnel, or in a power plant, with the Chemists. Whereas, in almost every plant, regular water analysis is being done at varied frequency (sometimes every two hours!) and the results are given to the shift-in-charge, who in turn fill the log sheet and then, more often than not, file it without giving any further consideration to the results. The decisions for any corrective measures to control the water chemistry regime are taken either by the chemist or by the DM plant personnel.

Very few O&M engineers know what are all the chemical parameters being checked regularly and most of them are having no or little idea about the significance and effect of these parameters on O&M.

The role of water chemistry is influenced quite a lot by operating conditions of a boiler and vice versa. On a number of occasions, when they interface, there are some grey areas, where the chemists think the responsibilities lie with the O&M guys, whereas, the O&M personnel feels that water is the exclusively the chemist’s responsibilities. But when something goes wrong as a result of that, who suffers?

An O&M engineer therefore should at least know what could be the consequences of faulty water chemistry. They should know the significance of each chemical parameter analyzed in water and should be able to identify when things start going wrong.

This programme offers the essential knowledge in a simple and logical manner, so that any one, who is not from a chemistry background, can also easily understand them.
