The use of an installation for feeding a mixture of coal dust and nitrogen made it possible to partially replace coke in the blast furnace process. This solution, introduced for economic reasons, contributed to reducing the costs of pig iron smelting by reducing coke consumption.
What did we do in the project?
We designed, performed calculations and developed construction documentation for the installation of pipelines for feeding a mixture of coal dust and nitrogen. The pipeline system included a technological line starting at a tank placed on the unloading vehicle, from where the mixture was transported by pipelines to a storage tank. There, after unloading, it was mixed with nitrogen again and then transferred to the burners of the blast furnace. The route of the installation was planned in a way that would allow for bypassing existing steel structures and other elements of the plant’s infrastructure, while maintaining optimal technical and operational parameters of the system.
Additionally, the project services included:
- classification of pipeline systems according to the directive,
- conducting calculations of pipelines and their supports,
- determining fixed and movable support points for pipelines.
