Design Of Solar Lime Kiln Omicsonlineorg

Lime kilns can be classified into three general groups; the vertical kiln, rotary kiln and the miscellaneous kiln. In this work, a rotary kiln was designed. Rotary kiln Rotary kilns are an advanced thermal processing tool used for processing solid materials at extremely high temperatures in order to cause chemical reaction or physical change.

Operations Strategies For Vertical Shaft Lime

primary advantage of vertical kilns over rotary kilns is the higher fuel efficiency. The primary disadvantages of vertical kilns are their relatively low production rates and the fact that coal cannot be used without degrading the quality of the lime produced. Other much less common kiln types include rotary hearth and fluidized bed kilns.

22 Lime Kiln Principles And Operations

8 Slide 15 Lime Kiln Heat Rate • Heat rate is a measure of energy efficiency – Units are MM Btu/ton CaO or GJ/tonne CaO – Often stated as MM Btu/ton “product” • Typical range – 5 to 9 MM Btu/ton CaO – 5.8 to 10.5 GJ/tonne CaO – Lower is better Slide 16 Lime Kiln Energy Balance Components • Drying • Calcining : CaCO3 + heat CaO + CO2 • Losses – Heat loss through shell
