oxy fuel fired rotary kiln for cement plant

captured from a 3000 t/d oxy-fuel cement kiln. Cost of CO 2 compression and purification ranges from about € 24/tonne to about € 27/tonne CPU is able to maintain CO 2 recovery of 90% with air intrusion rates of up to 6%. Cost increases by about € 1.50/tonne when air intrusion increases from 2% to 6%. Increasing CO

    Apr 01, 2019 To the knowledge of the authors, the present study (part of the H2020 EU project CO 2 capture from cement production - CEMCAP) is the first CFD modelling of a full scale rotary kiln in full oxy-fuel mode integrated into an entire cement plant. The study focuses on the optimization by CFD modelling of combustion in a full scale oxy-fuel retrofitted rotary kiln

    Jan 15, 2019 In contrast to the application of oxyfuel technology in power plant boilers, for the application in cement plants, changes in gas temperature and heat transfer to walls and material bed inside the rotary kiln must be considered, as they affect cement clinker formation , . A key question for retrofitting a cement plant for oxyfuel operation is whether conventional kiln burners can be used in oxyfuel
