Description

  • Content Description: A dual-screw feeder was designed and tested for desulfurization of coal. The key parts of this reactor are two screw tubes which independently feed coal and calcined lime, the inner tube acting as a coal pyrolizer and the outer tube acting as a desulfurizer with hot calcined lime pellets or other renewable sorbent pellets. The objective of this project is to study the feasibility of this advanced concept of desulfurization using the coal feeder. In this quarter, the following tasks have been performed: (1) Analytical measurements of the organic sulfur content in the feed coal and the product char, (2) setting up the combustor which is physically attached to the feeder system and will be used to study the combustion characteristics of char and volatiles produced from the pyrolysis process. The following preliminary conclusions have been obtained: (1) A 73.1% of the organic sulfur in Ohio {number sign}8 coal was removed in the dual-screw feeder reactor at a temperature of 475{degrees}C with the residence time of 6 min. (2) The combustor works stably and the operating temperature of the combustor can be adjusted by controlling the char feed rate and the air flowrate. 2 tabs.
