Inferred pH in Steam Plant Water Chemistry Monitoring

The x-axis is the con- centration of sodium chloride in the sample entering the cation column. The y-axis is conductivity of hydrochloric acid in the column effluent. In power plant chemistry conductivity is often called straight conductivity or specific conductivity to distinguish it from cation conductivity.

Ammonia absorption refrigeration cycle for combined cycle

Sep 17, 1996· To accomplish this the energy from the steam turbine condenser and/or other waste heat sources along with the favorable thermodynamic properties of ammonia are utilized to operate a refrigeration cycle cooling the ambient air entering the gas turbine compressor in a combined cycle power plant.:Applied Thermal Engineering · 1996:Douglas J Devault: Babcock Wilcox:Combined cycle · Power stationAmmonia-Fueled Gas Turbine Power Generationhttps://"The scale of facilities in experimental research for gas turbines is quite different from the gas turbines running in large power plants. The ammonia-fueled turbine used in our tests has an output of 50 kW maximum. This compares with turbines used in practical power plants that range from several tens to several hundred MW.
