handbook of burner technology for rotary kilns and flash dryers

2-2 Lime Kiln Principles and Operations8 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 ÄCaO + CO2 • Losses – Heat loss through shellHemp Dryers - Vulcan® Drying SystemsChopped hemp is fed into the rotary dryer by a feed conveyor. The dryer dries at low temperature by mounting a burner to a long combustion chamber to prevent direct contact with the burner flame. The burner flame is also cooled by a manifold of forced ambient air that passes through the combustion chamber as well.
