Abstract
The research was to model the geometry and flow conditions of the Shawnee Unit 10 Boiler during the dry limestone injection process. The basic goal was to determine the penetration and dispersion characteristics of the limestone injection. A cold-gas model was selected with a geometric scale factor of 12.5 to 1. The combustion gases and the solid-gas injection flow conditions in the boiler were simulated by keeping the values of the relevant dimensionless parameters for the model as close as possible to those of the full scale Shawnee unit. The degree of dispersion of the limestone was characterized by a percent coverage value which in effect is the fraction of complete mixing of the limestone and SO2. Percent coverage values were calculated for the Shawnee boiler for each of the three injection levels. The same was done for the model at one turbulence level and then additional tests were conducted at a fixed injection level under various turbulence conditions.
