Pulverization induced charge: In-line dry coal cleaning. Technical progress report No. 7, January 1, 1996--March 31, 1996

PDF Version Also Available for Download.

Description

Task 1 on charge determinations has been completed with additional measurements taken at the TVA Widows Creek plant. The probe which was designed and constructed for the field charge measurements proved to be effective in determining the average charge of pulverized coal particles. The charge measurements conducted at EKP`s Spurlock Station power plant and TVA`s Widows Creek plant have both yielded results which are in the same order of magnitude as those determined in controlled laboratory experiments. Under Task 3, coal separation determinations, separation tests performed on-site, combined with the charge measurements, showed that the charge generated by coal pulverization ... continued below

Description

Task 1 on charge determinations has been completed with additional measurements taken at the TVA Widows Creek plant. The probe which was designed and constructed for the field charge measurements proved to be effective in determining the average charge of pulverized coal particles. The charge measurements conducted at EKP`s Spurlock Station power plant and TVA`s Widows Creek plant have both yielded results which are in the same order of magnitude as those determined in controlled laboratory experiments. Under Task 3, coal separation determinations, separation tests performed on-site, combined with the charge measurements, showed that the charge generated by coal pulverization was sufficient for electrostatic separation of coal from mineral matter. These tests were conducted using a separation probe with different electric field strengths, i.e., different voltages were used across the two copper plates to generate the electric field. The results under four conditions were consistent and similar in terms of separation.
