Abstract

PURPOSE: To provide an energy-conservative no-pollution type quick lime producing apparatus with low NOx and low SOx which can be run continuously over a long term by combining a suspension preheater equipped with a fluidized bed calcination furnace with a suspension cooler without using a rotary kiln.
CONSTITUTION: Raw material powder limestone 16 is supplied to duct 1a of suspension preheater 5', preheated by cyclones 1, 2, 3, 4, and introduced 4b into fluidized bed calcination furnace 6. In furnace 6 fuel is burned with hot air 16a to calcine material 16, and the calcined material is separated by separation cyclone 8, introduced into duct 14a, and fed to cyclone 14 while being cooled with air of about 300°C fed from cooler fan 15 through suspension cooler 13. The material is then supplied 14b to cooler 13 through inlet 18, cooled finally to a temp. below 100°C by cyclones 10, 11, 12, and taken out 17 through shoot 12b. On the other hand, hot air of about 520°C leaving cyclone 14 is supplied 6a to furnace 6 as combustion air
