HLI was requested to provide support during the reconstruction of an existing coal-fired boiler for conversion to a new fuel—biomass. Changing the combustion technology in such facilities requires extensive expertise and installation experience in extremely confined and harsh environmental conditions. For this project, the HLI team designed a unique system along with a temporary structure mounted to the internal walls of the furnace chamber. The structure was essential for installing a set of wire rope actuators, which enabled the lowering, lifting, and horizontal adjustment of the boiler hopper weighing 40 tons. Due to technological requirements, the delivered system needed the capability to make horizontal corrections to the lifted load. This was achieved through specially designed sliding bearings and additional hydraulic equipment.
Scope of Work
- Component weight: 40 tons,
- Lifting height: 15 m,
- Design of the installation concept,
- Design of temporary structures,
- Supply of Strand Jacking technology and other hydraulic systems for vertical corrections of the transported element,
- Comprehensive vertical transport services.
Step 1
Installation of temporary structures inside the furnace chamber.
Step 2
Assembly of the lower part and the hopper walls.
Step 3
Installation of the hydraulic system along with the supporting structure inside the hopper.
Step 4
Positioning of the component to avoid collisions during lifting.
Step 5
Lifting the hopper to its final height, leveling it, and performing horizontal adjustments to position it in its final location.
