Abstract

This study deals with, energy, exergy,
specific energy consumption (SEC) and exergoeconomic assessment of a burner
(dry-type) in a currently running cement facility in Şanlıurfa, Turkey. The
exergoeconomic analysis of the unit is evaluated. The first and second law
analysis including exergy destructions and exergetic cost allotments are
analyzed for the unit. The first and second law efficiencies and SEC of the
kiln are calculated to be 54%, 29% and 3793 kJ/kg clinker respectively. The specific
cost method (SPECO) has been used for the exergoeconomic analysis. The
exergetic cost and cost rate and of the clinker product of the rotary kiln are
found to be 77.3 $/GJ and 2608 $/h, respectively.

Keywords
