Replacement of a part of the shell of the FMS shaft furnace

We have completed the project of replacing a part of the furnace shell at Vápenka Čertovy schody a. s. (Lhoist) in Tman near Beroun! The main objective of the project was the replacement of the unsatisfactory part of the furnace shell, to reinforce it and to install new combustion chambers.

The project included complete preparation of technical documentation, production and delivery of new shell parts and stiffening elements, as well as their subsequent dismantling and assembly. As the structural elements of the furnace structure were involved, all steps were planned and approved in advance by the structural engineer. Each step was coordinated with the utmost attention to stability, repeated measurements and comparisons with the original condition. Great emphasis was placed on completing the work in the shortest possible time and in compliance with health and safety regulations.

The preparatory work for the project was carried out over a period of ¾ year. The replacement itself took 4 weeks, with 16 workers on site working 24/7.
