Definition of Clinker. Clinker is a hard, black, or dark grey substance created when coal is burned. It's made of ash, soot, and minerals that fuse together at high temperatures. Clinkers can form on the fire grate, inside combustion chambers, or in flue pipes. These lumps can damage furnace components and reduce efficiency if not …
Clinker enters the cooler at 1400°C and exits at 100-200°C. Cooler efficiency is calculated as the heat removed from clinker divided by the total heat input. The efficiency depends on factors like intimate contact between clinker and cooling air, air quantity, and clinker granulometry. As a rough guideline, 68% of heat is lost in secondary ...

The clinker production phase at issue processes about 899000 tons per year of raw meal, using 59100 tons per year of fuel (coal); about 584000 tons per year of clinker are produced. Figure 1 depicts the process at issue. Initially, raw meal is entered into a suspension pre-heater (Fig. 1, left side), composed by four cyclones stages.
In this study the clinker cooler performance development is intended from the viewpoint of capacity increase and energy consumption using cement production plant actual figures. According to this analysis, the standard and actual cooler losses have been calculated as 519.16 kJ/kg.cl and 595.86 kJ/kg.cl, respectively.
Clinker formation is a serious problem in boilers of thermal power plants which results in forced outage and generation loss. Removal of clinkers from the water wall is difficult thus requires pneumatic hammering. Low quality coal having less gross calorific value, high mineral content, high ash content, and the over-firing of molten slag are causes of …
Subsequently, clinker is grinded and combined with other components, such as calcium sulfate or pozzuolan, obtaining the desired type of cement. The clinker production phase at issue processes about 899000 tons per year of raw meal, using 59100 tons per year of fuel (coal); about 584000 tons per year of clinker are produced.
