Nonequilibrium sulfur capture and retention in an air cooled slagging coal combustor. First quarterly technical progress report, September 14--December 31, 1995
The objective of this 24 month project is to determine the degree of sulfur retention in slag in a full scale cyclone coal combustor. This effort will consist of a series of up to 20 parametric tests in a 20 MMBtu/hr slagging, air cooled, cyclone combustor. During the present reporting period, this combustor was in the final stages of re-installation in a new facility in Philadelphia, PA following its relocation from a test facility in Williamsport, PA. Initial shakedown test on this new combustor facility began in December 1995, at the end of the present quarterly reporting period. The shakedown tests will continue through the next quarterly reporting period in the first three months of calendar year 1996. SO{sub 2} is controlled by injecting calcium oxide based sorbents into the combustor to react with sulfur emitted during combustion. The spent sorbent is dissolved in the slag and removed with it, thereby encapsulating the sulfur in slag. Part of the sorbent exits the combustor with the combustion products into the boiler where it can react with the sulfur. The primary objective of the present tests is to maximize the degree of sulfur retention in the slag. All spent sorbent not reporting to the slag is either deposited in the boiler or it is removed in the stack particle scrubber.
