Abstract

In this paper we have analysed
the impact of pet-kok on the increase of the quality of the calcine and the
reduction of the cost of Fe-Ni production in the new ferronickel foundry in
Drenas. The experimental and industrial research have
been analysed during the years 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016
and 2017, where it was analysed the decrease in the amount of heavy oil since
2011 where pet-kok begins to be used. Industrial and experimental researches of
attachments during 2009 and 2013, during the research we have proved the amount
of pet-kok used reduces the cost by 30-40% compared to the amount of heavy oil.
Growth of remelting
temperature over the analysed years, reduction of attachments in rotary kilns,
stability of fire-proof material in kilns in the case of reduction of the
attachment, reduction of cost associated with reduction of the gasses which
have a cost during their recycling process, including decommissioning channels,
termination process and transportation are some of the advantages of using oil
pet-kok as fuel in rotary kilns. The advantages in the metallurgical process
achieved with the growth of pet-kok fuel have influenced every year that its
quantity increases in relation to the heavy oil, both of which are used as fuel
in a rotary kiln to increase the temperature, which is one of the major factors
in increasing the quality of the calcination in the rotary kiln.
