The report summarizes data obtained to date under a contract relating to the use of dry sorbents to control SO/sub 2/ emissions from pulverized-coal-fired boilers. Experimental investigations are being carried out in parallel at two scales. (1) at bench scale, a boiler simulator furnace has been designed to identify the process parameters controlling sulfur capture by sorbent injection (this furnace will also be used to identify potential problem areas associated with the application of the technology in the field; and (2) at pilot scale, tests have been carried out with large (50 million Btu/hr firing rate and above) prototype low-NOx burners with sorbent injection (these tests were added to test series whose primary function was the optimization of the burner for flame stability and low-NOx operation). Since this is a progress report, it is inappropriate to draw conclusions from a study that is in its infancy. Data has been obtained which show that calcium utilization efficiencies of 25% are possible if the thermal history of the sorbent is controlled.
