Abstract

Abstract:

The project of environmental protection reconstruction for ultra-low emission of flue gas from active lime rotary kiln adopts the technology of desulfurization with baking soda powder.The baking soda powder (NaHCO3) is decomposed into sodium carbonate (Na2CO3) in flue gas.Because Na2CO3 is very active, it will react with acid substance in flue gas to remove SO2 and other acid substance. After the project was put into operation, the SO2 emission was nearly zero.

Key words:

"> Rotary Kiln, Baking soda powder, Ultra-fine grinding, Desulphurization, , Ultra-low emission

CLC Number:

TQ175.9
