pitting can result with possible rupture of boiler condensate piping or boiler tubes. 3.3.4 Rusty water in the boiler gage glass is a sure sign of acid corrosion in the boiler feedwater/condesate system or in the boiler itself. 3.3.5 Make-up water is the major source of carbon dioxide. The first priority is to minimize the amount of make-up water.

Dissolved Oxygen Test Kits – Boiler Feedwat

Maintaining Water Quality in High-Pressure Boilers Dissolved oxygen, or DO, is one of the most important water quality parameters to control in a boiler system. It is the primary corrosive agent of steam-generating systems. Even low concentrations of DO can be highly destructive, causing localized corrosion and pitting of metal system components.

Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica, phosphates etc, in relation to working pressure. The actual …

Boiler Efficiency and Steam Quality: The Challenge of .

But it can also affect steam quality. Increased TDS in the boiler water causes increased foam production on top of the water. This low-density, two-phase system's foam is produced and easily entrained by the steam rising out of the water. As rapid drops in steam pressure caused by demand increases, this foam can be drawn into the steam system ...

better results in boiler water treatment (i.e., cleaner boilers). The important key to success is to use the same care in selecting, applying, and controlling the treatment program. Chelating programs are another variation of water treatment. The word chelate derives from the Greek word chele, meaning claw. This was probably chosen because of the
