Electro Magnetic

The effects of anti-scale, anti-corrosion and disinfection of circulating cooling water with electro-magnetic treatment and chemical treatment in the laboratory are compared. The applications of electro-magnetic treatment in power plants are summarized and discussed. The results of both experiments and applications in power plants show that the electro-magnetic treatment can be used in particular conditions, but the development of electro-magnetic treatment technology is immature. This technology used in circulating cooling water system in power plants should be further proved by more experiments and field applications.

Cooling Water

With today’s growing restrictions in sources and chemical treatment, cooling water that has low corrosive potential is difficult to find. Today’s sources are more aggressive (corrosive) creating a greater challenge to the survival of tubing materials. Pitting and crevice corrosion have become much more common. This paper identifies and summarizes those changes, concerns, and provides suggestions on how a utility can prevent long-term problems. It will cover the water factors to consider and monitor, proper lay-up practices, and material selections based on cooling water chemistry and practices.

Pressure Switch

High vacuum systems with oil diffusion pumps usually have a pressure switch to protect against Insufficient cooling water; however, If left unattended for long periods of time, failure of the mechanical fore pump can occur with equally serious results. The device shown schematically in Fig. 1 has been found to give effective protection against both these failures, yet it is inexpensive and relatively simple to build and operate.With this system, pressure in the fore pump line is measured by thermocouple vacuum gage TVG (CVC G.TC-004) whose output is monitored by meter relay MRy (Weston 1092 Sensitrol) which is set to close if the pressure rises above about 0.2 torr. This energizes control relay CRy (Potter & Brumfield KA5Y 120VAC SPDT) cutting off power to solenoid-operated fore line valve Vf (Cenco 94280-4 Norm. Closed) which closes to prevent further leakage of air into the diffusion pump
