APPLICATION OF PULSE CORONA INDUCES PLASMAS FOR CONTROL OF NOx FROM JET ENGINE TEST CELLS

Jet engine test cells are faced with meeting regulations related to NOx emissions and opacity. Based upon reported research results, it appears that the Pulse Induced Plasma Chemical Process (PPCP) could be effectively applied to jet engine test cells for the control of NOx. The process provides high efficiency NOx removal at relatively low temperature without the need for NH3 injection. PPCP can be designed for a flow-through configuration which could be installed in a test cell with minimal pressure drop. In addition, VOCs present in the exhaust stream would be destroyed and particles would be collected by this system. The primary objective of the Phases I program is to determine the technical feasibility of developing PPCP for jet engine test cells. This requires the design and testing of components that can be incorporated into a control system that will fit the specific geometric constraints of size, flow rate, and pressure drop necessary for use in the existing test cells. The Phases I effort will involve a laboratory study to evaluate several key subsystems of the proposed technique and develop data required for designing a prototype full-scale test system.
