Sodium Monitoring In The Water And Steam Cycle In Power Plants
Today sodium concentration has become one of the most important indexes for quality control of water and steam at power plants; however, measurement of this parameter can be difficult in practice. The use of ion selective electrodes means that analyzers are sensitive to pH shifts and constant exposure to very low concentrations of sodium ions in ultra-pure water conditions can lead to electrode desensitization. In addition, there is a need to address drift through regular calibration.
Ion Exchange Treatment Of Regulated Metals In Coal Ash Found To Be Efficient In Power Industry
Coal ash is a waste product of coal combustion used for electrical power generation. Fly ash (from smoke stacks) and bottom ash (from boilers and combustion chambers) may contain trace metals including aluminum, arsenic, cadmium, chrome, copper, mercury, nickel, lead, selenium, vanadium, and zinc. This ash is removed from the boiler using a water slurry and stored in holding basins or ash piles within the power generation facility.
