Limestone Attrition and Product Layer Development during Fluidized Bed Sulfation

Limestone is widely used as a sorbent in fluidized bed combustors. The study of limestone attrition characteristics is significant for mass balance and desulfurization efficiency. The present study investigates the sulfation and attrition behavior of limestone in a bubbling fluidized bed reactor. The product distribution and development of the product layer are analyzed by scanning electron microscopy. The experimental results show the attrition...
