Water quality with high-efficiency boile

Aug 11, 2016· But eight out of ten hot water boilers we install are high-efficiency condensing boilers. With high-mass, cast iron hot water boilers, I never really gave any thought to the quality or treatment of the system fill water. I would drain the system, cut the old boiler Zozene, connect the new boiler, fill and purge, and be on my way.

Water Quality Program - Commercial Boilers & Water Heate

The accepted standard through the boiler industry has required a derating of the boiler, based on the percentage of glycol in the boiler water. The de-rate factor is 0.2% for each 1% of glycol in solution. For example, a 50% Propylene solution would require (0.2 x 50) a 10% derating Water Quality Program for All Patterson-Kelley Boilers

Plant Engineering | Maintaining boiler safe

Typical industrial boilers are natural circulation and do not utilize pumps to move water through the tubes. Instead, these units rely on the differential density between steam and water to provide the necessary water circulation. The water level is critical to ensure a flooded supply of water to downcomer tubes (Fig. 3).

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…

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.
