    摘要： Methods and apparatus for monitoring and controlling pH, phosphate, and sodium to phosphate ratio in boiler systems operating with captive alkalinity chemistry are described. The methods for monitoring and controlling these parameters include the steps of determining the phosphate concentration via FIA, determining the pH, and using these values to determine the sodium to phosphate ratio. These values are then compared to the optimum values for the boiler system being treated; on the basis of this comparison, adjustments to the feed rate of water treatment chemicals being added to the system are then made. The apparatus includes a device for determining phosphate concentration via FIA, a device for determining pH, a means for determining sodium to phosphate ratio and a device for adjusting the feed rate of water treatment chemicals being added to the system. The device for adjusting the chemical feed rate is computer controlled.
