Abstract
The report describes an evaluation of the mixing of jets of calcium based sorbents injected into large wall-fired coal burning utility boiler furnaces for sulfur dioxide (SO2) emission control. Pilot scale combustion experiments at 1.41 and 24 MW thermal input tested the dependence of overall sulfur removal efficiency on injection parameters and sorbent type. Several computational and empirical models of jet behavior were adapted for use in sorbent injection system design. An effective injection system design methodology is based on a hierarchy of design and interpretation procedures. The methodology includes: (1) use of simple empirical jet relationships to provide preliminary estimates for injection system parameters (number, size, and velocity of jets); (2) isothermal physical flow modeling of the boiler to evaluate and optimize injection system mixing parameters; and (3) coupling of jet mixing results with experimental sorbent sulfation data, or sulfation calculations, to predict the impact of mixing on overall SO2 capture.
