HIGH TEMPERATURE CONDUCTIVITY PROBE FOR MONITORING CONTAMINATION LEVELS IN POWER PLANT BOILER WATER

water (Dooley et al., 2002). At higher temperatures, the ammonia associates, so that the conductivity measured at higher temperatures is almost purely due to additives other than ammonia, which, in this case, are the contaminants in the boiler water. With

Plant Engineering | Maintaining boiler safety

Low-water trips protect boiler pressure parts by shutting down the fuel combustion process, eliminating high temperatures in the furnace when the natural circulation cooling process is interrupted. Control of the boiler drum level is sophisticated, and even the best-tuned control systems cannot always prevent a low-water condition.

High conductivity or contamination of the boiler feedwater can create other problems such as drum level instability and foaming. This can result in high or low-water alarms and an increase in the carryover of moisture droplets into the steam header since the moisture separator of the drum cannot handle the resultant carryover.

The water being drained from the boiler is at saturation temperature, and there is a drop in pressure over the orifice almost equal to the whole boiler pressure. This means that a substantial proportion of the water will flash to steam, increasing its volume by a factor of over 1 000.

Inferred pH in Steam Plant Water Chemistry Monitoring

In higher-pressure boilers, a soluble, inert material may be added to the boiler water as a tracer to determine the percentage of blowdown. The formula for calculating blowdown percentage using chloride and its derivation are shown in Table 13-1.
