Pulverization induced charge: In-line dry coal cleaning. Technical progress report {number_sign}6, October 1--December 31, 1995

PDF Version Also Available for Download.

Description

Direct firing coal pulverization systems, both pressurized and suction types, are the predominate design for utility pulverized coal (PC) boilers. Pressurized systems incorporate a fan prior to the pulverizer, which blows prepared coal after pulverization through a classifier and into burner pipes. Suction systems utilize an exhauster fan to pull prepared coal after pulverization through a classifier and blows the coal into the burner pipes. On-site measurements on a pressurized system at the Spurlock Station of East Kentucky Power in Maysville, KY have already been performed, the results from which were presented in previous reports. During this quarter, a second ... continued below

Suction systems utilize an exhauster fan to pull prepared coal after pulverization through a classifier and blows the coal into the burner pipes. On-site measurements on a pressurized system at the Spurlock Station of East Kentucky Power in Maysville, KY have already been performed, the results from which were presented in previous reports. During this quarter, a second series of on-site tests were performed on a suction pulverizer system at the Widows Creek Plant of the Tennessee Valley Authority (TVA) in Stevenson, AL. The report presents data on these tests and discusses accomplishments under each task: pilot scale test rig development; coal separation determinations; and full-scale separator design. No work has commenced as yet on the economic evaluation.
