Mill inlet temperature should not exceed 315°C and coal should not be dried to below 1% surface moisture. Mill discharge temperature is lim- ited to 65°C for indirect systems and 80°C for direct. Carrying air veloc- ity must be maintained above 20M/sec to avoid dust settlement (Recommended Guidelines for Coal System Safety; PCA; May 1983).

Heat loss distribution across different elements can be established through heat balance and process audit of pyro section. Fuels used commonly to provide heat for the conversion processes are coal, fuel oil, and natural gas. Alternative fuels like petcoke, rubber tyres, wood chips, etc. have been introduced to economize cement making process.

Heat transfer from this flame and the hot combustion gases that flow up the kiln dries, heats, and calcines the counter-flowing lime solids. Rotary lime kilns in the pulp and paper industry range in size from 7 ft (2.1 m) in diameter by 175 ft (53 m) long to 13.5 ft (4 m) in diameter by

First is the KILN, this provides the heat, The BURNER is inside this portion. The fuel for the burner is usually diesel although heavy crude oil could be used in some cases. To be able to generate enough heat to dry the concentrate air must be added by way of a BLOWER. In front of the kiln is the point that the wet concentrate enters the drier.

By using a HRSG for recovering the waste heat from the exhaust of a 60-MW gas turbine, an additional power of 35.14 MW can be generated, thus increasing the overall plant efficiency from 33% to 52%. The heat transfer coefficients of gas are weak; therefore, the designed HRSG has a large area to produce steam at high pressure and temperature.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Heat transfer processes are classified into three types. The first is conduction, which is defined as transfer of heat occurring through intervening matter without bulk motion of the matter. Figure 1.1 shows the process pictorially. A solid (a block of metal, say) has one surface at a high temperature and one at a lower temperature.
