Description:
The report describes a program to develop design criteria for injecting dry sorbents into tangentially fired coal furnaces for the control of SOx emissions. The program included aerodynamic cold-flow testing and mathematical modeling of sorbent injection, demonstration testing of SOx emissions control in a 14.7 MW thermal (50 million Btu/hr) tangentially fired Boiler Simulation Facility (BSF), and development of recommendations for sorbent injection in a tangentially fired boiler demonstration of the process. The isothermal flow modeling led to development of sorbent injection systems for tangentially fired furnaces which provide high levels of sorbent dispersion. A sorbent dispersion mathematical modeling technique was developed to support flow modeling in identifying and optimizing sorbent injection locations and methods. A procedure was developed for specifying sorbent injection locations and methods for a full-scale demonstration of the sorbent injection process in a tangentially fired utility boiler.
