Boiler Water Quality Requirements and Associated Steam Quality. Boiler Water Quality Requirements and Associated Steam Quality for Industrial and Commercial and Institutional Boilers by ABMA (American Boiler Manufacturers Association). The purpose of this manual is to acquaint engineers, purchasers, and operators of industrial, commercial and institutional (ICI) boilers with ABMA’s judgment as to the relationship between boiler water quality and boiler …View More
Water Hardness is the primary source of scale in boiler equipment. Always use a softener to ensure good Boiler Water Quality. Chemicals are designed to polish away small amounts of hardness that by-passes the softener. Silica in boiler feedwater can be a problem in larger steam boiler systems. You must maintain a Total OH alkalinity ratio of 3:1 in high pressure boilers to prevent plating of silica.View More

The task of any steam boiler is to provide the correct amount of high quality steam: safely, efficiently, and at the correct pressure. Steam is generated by heat from the combustion of fuel in a furnace, or by waste heat from a process. The heat is transferred to water in the boiler shell, which then evaporates to produce steam under pressure.View More
Steam quality is a measurement of the amount of water entrained in the steam. It depends not on the efficiency of the boiler but on the ability of the steam to separate from boiling water, without carrying liquid water particles with it throughout the entire range of boiler operations.View More
Poor water quality was the cause. Water treatment is especially important when matching a new condensing boiler to old gravity systems with massive cast iron radiators and large steel mains. Iron oxide, sludge, sediment and other dissolved contaminants in the system water come out of solution at the hottest part of the system: the heat exchanger.View More
Water Quality is important to the proper operation of the boiler. The following information on water quality provided in this document must be followed. Damage caused by failure to follow these requirements may not be covered by the manufacturer’s warranty. During installation and yearly maintenance, the water quality must be checked.View More
Since water impurities cause boiler problems, careful consideration must be given to the quality of the water used for generating steam. The composition of boiler feed water must be such that the impurities in it can be concentrated a reasonable number of times inside the boiler, without exceeding the tolerance limits of the particular boiler design.View More
Whether caused by low water or poor boiler water quality, potentially dangerous steam explosions can occur when overheated pressure parts suddenly fail under high pressure. A steam explosion in a boiler house can, in seconds, produce ambient conditions of intolerable heat and reduced oxygen levels below survivable limits.View More
Steam purity can be measured with the use of a sodium ion analyzer. It measures the sodium ion content in a cooled steam sample that will correspond to the amount of boiler water solids contaminating the steam. The sodium ion analyzer can detect carryover down to 1 …View More
Water treatment recommendations vary depending on the operating pressure of the boiler, the application (steam or hot water), and other parameters. General guidelines to prevent corrosion and scaling in low pressure boilers are as follows: Total Hardness 1 PPM Maximum Total Alkalinity 600 PPM MaximumView More
Boiler water quality has long been an important factor in the operation of boilers. As the power plant operating pressures increase, water quality requirements also become stricter. With the current units operating at Supercritical pressures, the requirements are tough. Continuous improvements and changes in the methods of maintaining water quality, understanding the corrosion mechanisms, and the …View More
in boilers and feedwater tanks, the water should be thoroughly mixed with an adequate amount of oxygen scavenger and heated to boiling while being vented to drive off oxygen at the start of storage. 3.3 Acid Corrosion 3.3.1 Raw water, as received through the city mains or …View More

Boiler water is liquid water within a boiler, or in associated piping, pumps and other equipment, that is intended for evaporation into steam. The term may also be applied to raw water intended for use in boilers, treated boiler feedwater, steam condensate being returned to a boiler, or boiler blowdown being removed from a boiler.
