Czech Republic (steel plant)

Arcelor Mittal

RJM recently won a major project from Czech EPC contractor CKD Group to reduce emissions at ArcelorMittal’s steel plant at Ostrava in the Czech Republic.

The steel plant burns coal and gas but the real challenge for RJM’s combustion engineers and CFD modellers was integrating the low NOx combustion of low volatile coal with the combustion of re-circulated Coke Own Gas (COG) and Blast Furnace Gas (BFG) - and yet still ensure full IED compliance.

Following an in-depth site survey and CFD modelling work, RJM devised a solution that included the installation of its own Ultra-Low NOx Burners on all three boilers, together with a fully-optimised OFA system. The objective is to ensure emissions compliance of 320 mg/Nm3 using only primary measures.
