Abstract

The role of thermal efficiency of the calciner is very important because it describes the performance of the calciner,  whether or not the performance of the calciner can be seen from the efficiency of the thermal calciner. The thermal efficiency of  the calciner obtained  based on the calculation of the Mass Balance and Heat Balance ranges from 75,59%-79,74% with an average  actual thermal efficiency of 77,26% while for the average heat loss of 22,74%. The results of efficiency calculations show that the performance  of the calciner tool in terms of thermal efficiency of the calciner unit  is quite efficient and still good for use, because it is characterized by the efficiency of the thermal calciner unit is still included in the range of  thermal calciner efficiency by design. From the average amount of CO2 produced from calcination of 100.033,7376 kg/hour and fuel combustion of 43.201,24151 kg/hour, will have an adverse impact on the quality of the surrounding air. So it must be minimized in the use of coal and maximize efficiency in the kiln system.

Abstract

Grate cooler adalah alat pendingin yang letaknya setelah rotary kiln.Udara pendingin cooler didapatkan dari hembusan dari 13 unit fan. Udara ini akanmendinginkan klinker yang keluar dari kiln dengan metode pendinginan secara cepat atau disebut juga metode quenching. Grate cooler merupakan pendingin yang paling modern. Pada awal perkembangan pemakaian grate cooler dimaksudkan untuk mendapatkan laju pendinginan yang cepat dengan tujuan mengurangi pengaruh kristal periclase, sehingga diperoleh kualitas klinker yang baik, perpindahan panas yang baik sangat mempengharui cooler jenis ini agar dapat menerima klinker dengan temperatur ± 1400 – 1200 ?. Perpindahan yang terjadi di alat ini adalalah pada kondisi cross current dan counter current. Peralatan grate cooler tidak bisa dipisahkan letaknya dari kiln karena terpasang langsung menyambung pada outlet kiln.
