Reconstruction works on chimneys of Hot Water Boilers 1, 2 and 3, disassembling and replacement of insulation with corrosion protection works

PROJECT DESCRIPTION:

The chimney reconstruction project included the disassembling of old and the installation of new cylindrical chimney parts, with suitable climbers, platforms, fences and complete insulation of said elements. The replacement of the chimney was done from the elevation of + 36.50 m, and the insulation replacement was done from the base starting at the elevation of + 28.50 m, up to the elevation of + 80 m, which is the height of each chimney.

The cylinder-shaped shield of the chimney was manufactured in three segments of equal length in our factory in Pančevo. Transport from the workshop to the place of installation was carried out by special vehicles, due to the length of segments of 14.50m, and due to the diameter of the cylinder 3.80m (internal diameter). All segments were formed by welding on the construction site, and then lifted using 600t and 200t lifting cranes.

Boiler specifications:

  • Individual boiler power HWB1, HWB2 and HWB3 (utility boiler 105): 105 MW
  • Manufacturer of hot water boilers: SGP (Simmering Graz Pauker AG)
  • Fuel: low or medium heating oil (Mazut)

Boilers HWB1, HWB2 and HWB3 are utility boilers and are part of a gas turbine block. Utility boilers can operate independently while using crude oil as fuel. The boilers operate at a constant output temperature of 180°C.
