| description | The work objective is to improve the operational conductometric vapor quality control at the thermal power plants. To this end, methods identifying СО2 concentrations in the vapor under the neutral aqueous-chemical mode without ammonia addition are developed. The technique of measuring the steam condensate conductivity at the operating pressures of steam generators and at different temperatures is used. The implementation of this method with the use of a special device significantly reduces the control response rate and differentiation of impurities. The experimental data on the first apparent dissociation constants and the limiting equivalent conductance of the carbonic acid, dissociation constants, and the limiting equivalent conductance of NaCl in the liquid phase on the saturation line are analyzed. On the basis of this analysis, an error in determining СО2 concentration and the impurities in vapor in the form of NaCl by the proposed method is estimated. The approximation error for the dependencies describing the dissociation constants behavior, and the limiting equivalent conductance of the carbonic acid, which can be used in the calculation of the concentrations by the proposed methodology, as well as during the organization and management of water chemistry, is estimated. |
