Boiler Circulating Pumps, Auxiliary Cooling Water Pumps

Jul 30, 2013 · A. Auxiliary cooling water pumps (see Figure 6.15) usually operate in a closed-loop system using high-quality water. The water received from the circulating water pumps moves through the tube side of the auxiliary cooling water heat exchanger. The auxiliary cooling water circulates through the shell side and is cooled.

Chemical Treatment of water for Cooling and Heating Systems

Drift - Water lost from a water-cooling tower as liquid droplets entrained in the exhaust air, units: kg per hour or percent of circulating water flow. Feedwater - The water supplied to a boiler to make-up for losses. Floc - Any small, tufted, or flakelike mass of matter floating in a

Boiler Water Circulation Pumps - SlideShare

Boiler feed water quality is limited owing to problems of (1) scaling, (2) corrosion, and (3) foaming. In order to avoid these problems, the quality guidelines shown in Table IV have been adopted. Data in Table IV show a major difference between cooling water and boiler feed water quality constraints, in that boiler feed water has a strong relationship between water quality and the pressure of
