Experimental calculation of the main characteristics of thermoelectric EMF source for the cathodic protection station of heat supply system pipelines

Abstract

The scientific paper considers the design of an experimental thermoelectric power source for cathodic protection station of heat network pipelines from electrochemical corrosion; It allows you to utilize lower-grade heat with subsequent direct conversion into electricity in thermoelectric converters which are made of two metals with different thermionic properties using the effect of thermoelectricity. In this case, the generated electric current can be used as an autonomous power supply for the cathodic protection station. The experimental technique has been developed, as well as experimental studies have been performed with the subsequent analysis of the main characteristics of thermoelectric generator.
