Reconstruction of boiler type LMZ-90/34 Art. № 4 installed on PEVS PJSC "IC" Azovstal ", 2012

In 2012 PJSC "Interenergo" Run Project reconstruction of boiler type LMZ-90/34 Art. № 4, mounted on PEVS PJSC "IC" Azovstal" in Mariupol.

The existing boiler type LMZ-90/34 Art. № 4 is not present on the design requirements, the deteriorating quality of the source water in the Donetsk region. As a result, the boiler blowdown is unrealistically high (over 10%), leading to a significant loss of heat, the boiler water and steam underproduction.

The Project's technical solutions, the following key elements to the reconstruction of the boiler:

  • Replacement of the existing devices in the separation of the first stage of the upper front drum with new ones;
  • Replacement of the existing devices in the separation of the first stage on the upper rear drum louvre-throttle separators and install new perforated ceiling;
  • Installation of 6 cyclones in the upper rear drum (the second stage of evaporation);
  • Organization of the third stage of evaporation in two remote cyclone installed from the front of the boiler;
  • increase the degree of screening furnace by installing two additional panels side screens from the front and the increase in the ceiling of the heated surface (the front) of the screen;
  • changes in the number and trace water-supply pipes and parootvodyaschih, with reconstruction schemes circulation.

Implementation of the project will enable the production of steam boiler ratings and the quality required.
