Evaluation of Rocket Research Company's Plasma Torch for NOx Reduction Studies CRADA PC93-001, Final Report

PDF Version Also Available for Download.

Description

Combustion and Environmental Research Facility (CERF) formerly known as The Fuel Evaluation Facility was used from March 29 to April 17, 1993 for the sole purpose of evaluating the Rocket Research (RR) plasma torch and testing its effectiveness in reducing NO{sub x} emissions from coal flames. Two spare facility convective sections were modified to accept the torch and to allow for effective mixing in the convective section chambers. The torch was placed into the fourth convective section and a 1-inch fused silica bluff body was placed immediately upstream of the torch to further enhance the mixing at the torch injection ... continued below

Description

Combustion and Environmental Research Facility (CERF) formerly known as The Fuel Evaluation Facility was used from March 29 to April 17, 1993 for the sole purpose of evaluating the Rocket Research (RR) plasma torch and testing its effectiveness in reducing NO{sub x} emissions from coal flames. Two spare facility convective sections were modified to accept the torch and to allow for effective mixing in the convective section chambers. The torch was placed into the fourth convective section and a 1-inch fused silica bluff body was placed immediately upstream of the torch to further enhance the mixing at the torch injection location. The gases anticipated for use during testing included ammonia (NH{sub 3}) , hydrogen (H{sub 2}) , carbon monoxide (CO), and methane (CH{sub 4}). Ammonia and hydrogen were planned as the gases which would be introduced through the torch directly while CO and CH{sub 4} would be used only in the torch secondary injection ring. The intent was to minimize any potential fouling problems with the carbon containing gases. Actual test conditions did not allow evaluation of the CO or the CH{sub 4} due to continued intermittent operation of the Rocket Research plasma torch. The torch had not been previously tested under conditions similar to the high temperature condition of the CERF and consequently it was found that the torch would not operate effectively under the test conditions. The torch using NH{sub 3} and H{sub 2} as primary and secondary gases has evaluated for short periods of time.
