KILN STARTUO FUEL REQUIREMENT & FLOWRATE ADJUSTMENT

I presume you mean diesel or gasoil by HSD? Light up burners normally supply about 5% of the normal operating thermal energy input and have a turn-down ratio of 10:1. To start up it is normal to begin with the burner at it’s minimum setting so about 0.5% of the full production heat input. The flow rate is then increased in order to follow a planned temperature rise as monitored by the kiln inlet temperature (your system is inadequate in not having this sensor). The coal firing can begin when the temperature in the burning zone is sufficiently high to ensure the ignition of the coal. You will face particular difficulties with the SLC kiln as no kiln exhaust gas is passing through the calciner. You must wait for clinker to be delivered into the cooler and the tertiary air temperature to rise sufficiently or provide light-up burners in the calciner before feed can be delivered to that preheater string.
