Contamination created inside heater exchangers and the method of its removal


The decrease in heat exchanger due to contamination on the surface of the tubes and, consequently, the decrease of efficiency of condensers in steam turbines generates high losses related to the decrease of power unit’s efficiency. The only method of fast recovery to the operating parameters of such equipment is to clean the heat-exchanging surfaces.


The most effective of today’s methods for cleaning the condensers in steam turbines is hydrodynamic cleaning with high-pressurised water where the pressure reaches 300 MPa. Ecol professionals choose the optimum pressure of the cleaning agent for the specific technical conditions in the condenser, as well as the level and type of contamination.


Hydrodynamic cleaning of condensers in steam turbines


The technology in question requires the introduction tubes properly prepared nozzles installed on special wash pipes into the condenser and operating with water jet having proper parameters (pressure and efficiency). High-energy water jet splits and cuts all the deposits from inside the tubes.


For many years, we have gained experience, and gathered equipment and tools allowing us to remove contamination from any type of heat exchanger.


Advantages of hydrodynamic cleaning of condensers:


  • very high cleaning effectiveness, allowing detaching even the strongest deposits;
  • high mobility—Ecol’s mobile equipment mounted on an automobile body allows cleaning at a distance from the power source (hydraulic power unit with combustion engine) and fast relocation;
  • possibility of use also in case of completely clogged tubes;
  • possibility of use in the U-shaped heat exchangers;
  • no need for use of any chemical agents—water as the only cleaning agent;
  • fast performance.


Ecol offers hydrodynamic cleaning of heat exchangers of the following type: condensers in steam turbines, tube and plate heaters of all media, as well as all types of gas, oil, water, and other media heat exchangers.
