Description

The limestone-SO/sub 2/ reactivity as determined on a thermogravimetric analyzer was used to estimate the quantity of limestone required to meet the SO/sub 2/ emission standard in atmospheric fluidized-bed coal combustors. Comparison of laboratory TGA calcium utilization with pilot plant experimental results were made. Estimates of SO/sub 2/ retention in a carbon burnup cell were made for various limestone feed options. From this information, estimates of limestone requirements for an AFBC-CBC system were made for Tymochtee dolomite and for Greer and Germany Valley limestones. The results indicate that dolomites may require smaller quantities to meet the SO/sub 2/ standard than … continued below
