The pulverization of coal is performed in the coal mill, while the hot flue gasses from PH (Hfg 4) are used for preheating and drying of the raw coal. The stream of preheated coal (Fl ph) is then transferred into the rotary kiln burner. A planetary clinker cooler (CC) is used to cool down the clinker from approximately 1400°C to 100°C.
When clinker cooler air is used for coal mill heating, the fine carryover dust can add large amounts of inert 'ash' to the ground coal. This can interfere with combustion and limit kiln output. The abrasive dust also accelerates equipment wear and makes burner pipe and snowmen buildups more likely.

A method of controlling the generation of clinker ash from exhaust gas dust comprising controlling the formation of clinker ash in a boiler, furnace or the like which employs dust coal as a fuel by adding to a fuel at a mill installed in a fuel line or at a point upstream of the mill a mixture of at least one iron compound in an amount of 2 ...
Re: why slagging in boiler. 05/21/2009 11:05 AM. Slagging is because of the minerals present in coal. the temp of the boiler in the combustion zone is the order of 1400 deg C. The minerals present in coal ash bring down the ash fusion temperature and at low temps as low as 1200 Deg C the ash melts and fuses and causes slagging/clinker.
