IMPACT OF CATALYTIC FUEL ADDITIVE ON CLINKER PRODUCTION PROCESS

Keywords: clinker, rotary kiln, catalytic additive, specific energy consumption, alite

Abstract

Industrial studies of the effect of supplying a liquid catalytic fuel additive to 4 clinker kilns operating according to the dry method on the quality characteristics of clinker, the operation of technological equipment and environmental indicators have been carried out. The supply of REDUXCO catalytic additive with a flow rate of at least 100 mg/t of fuel into the primary air channels of the furnace burner and the air supply channels to the calciner helped to reduce the specific energy consumption of fuel by 3.6–6.7% when using anthracite as fuel; for petroleum coke - by 3.4–3.6%; mixtures of coal and RDF - by 5.7%. An increase in the content of alite - the main component of clinker - by 0.46–0.9% and a decrease in the content of free calcium oxide by 0.9% as a result of an increase in temperature in the sintering zone due to the intensification of gas-phase combustion reactions. Experimental confirmations of the improvement of the stability of the clinker kiln operating modes and the reduction of the carbon monoxide content in the exhaust gases were obtained.
