Description
Summary:The proposed work is intended for operational staff and employees of project organizations. The possibility of modernization of sampling devices for superheated steam sampling in automatic chemical control systems at thermal and nuclear power plants is considered. The results of calculating the flow rate and the inlet diameter of the superheated steam sampling device are presented. A nomogram has been developed to determine the required diameter of the inlet of the sampling device. Two cases were modeled of sampling in the software package Ansys, confirming the need to modernize the design of standard devices for steam sampling.
