WebUses & Applications of Phosphates in Boiler Water Treatment Boiler water treatment systems are used to handle many adverse conditions due to the extreme temperatures and related pressures of boiler systems. Some of these conditions include scale/deposits that form on the inside walls of piping and corrosive boiler feedwater. These WebBoiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser. From the condenser it is then pumped to the deaerated feed tank.
WebBlowdown control. Boiler blowdown is the removal of water from a boiler. Its purpose is to control boiler water parameters within prescribed limits to minimize scale, corrosion, carryover, and other specific problems. Blowdown is also used to remove suspended solids present in the system. Webadditions to the boiler. Figure 1 — Normal congruent phosphate-pH boiler chemistry. Figure 2 — Phosphate hideout caused by lower combustion zone. The best way to recognize phos-phate hideout is to graph load changes, pH, and phosphate over a period of time. The variations of the graphs will clearly indicate that the phosphate increases with
