Project

LKAB (Luossavaara-Kiirunavaara AB) is an international company that produces 
iron ore products for the steel industry; their main product is iron ore pellets.


The aim with this research project is to numerically investigate if it is possible to use 
selective non-catalytic reduction (SNCR) technologies in grate-kiln pelletizing 
plants for NOx reduction. The technique had, to the best knowledge of the author,
never been used in this context before despite that it is commonly used in cement 
and waste incineration plants. The investigation is done in several stages:

1) Reveal if the technique is possible to use with the two most commonly reagents ammonia 
and urea.

2) Derive a chemistry model for cyanuric acid so that this reagent also can 
be scrutinized.

3) Compare the reagents urea and cyanuric acid in the grate-kiln 
pelletizing process.
