Summary

Microbiological activity and deposits caused localized corrosion in a district heating system, despite water meeting strict chemical limits. Modifications and monitoring now aim to prevent future microbiologically influenced corrosion.

Area of Science:

  • Materials Science
  • Microbiology
  • Corrosion Engineering

Background:

  • Localized corrosion and microbiological activity were observed in AISI316 stainless steel heat exchangers.
  • Black deposits containing bacteria and sulfides were found on the boiler side.

Purpose of the Study:

  • To investigate the cause of localized corrosion in a district heating peak load unit.
  • To identify the role of deposits and bacterial activity in the observed corrosion.

Main Methods:

  • Inspection of heat exchangers and boiler system components.
  • Analysis of deposits for bacterial and chemical composition.
  • Investigation of corrosion sites in areas with stagnant or low water flow.

Main Results:

Related Experiment Videos

  • Significant bacterial presence was detected, particularly within deposits and near corrosion sites.
  • Corrosion incidents on low alloy steel were linked to organic matter and bacteria in stagnant water areas.
  • The combination of deposits and bacterial activity was identified as the primary cause of corrosion.

Conclusions:

  • The study suggests microbiologically influenced corrosion (MIC) was occurring.
  • System modifications were implemented to mitigate MIC risks.
  • A monitoring program for fouling and corrosion was established for ongoing management.
