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.Keywords : humidity, pet-kok iron-nickel, rotary-kiln, heavy oil
