Reducing the rate of corrosion and scale formation in heating mains and circulating cooling systems

  • Published:
Power Technology and Engineering Aims and scope

Measures to reduce the rate of internal corrosion of piping in heating networks are described, including: raising the mains water pH, reducing the oxygen content in feed and mains water to established norms, introducing direct monitoring of the oxygen content in heating systems, using corrosion inhibitors, and installing corrosion indicators. A test stand is constructed for determining the antiscaling efficiency of various complexones. Based on the test results, a method for antiscaling treatment of mains water and the water in circulating cooling systems is developed and introduced in a number of installations.
