Chemiluminescence-Based Feedback Control of Equivalence Ratio for a Continuous Combustor

摘要: Recent pollution requirements and stringent operating conditions for gas-turbine engines have prompted the need real-time feedback control of combustion processes power production propulsion. NO CO pollutants from been focus many researchers some time. By accurate equivalence ratio (EQR), fluctuations caused by low-frequency air flow rate disturbances may be avoided to maintain desired levels CO. In this paper, we develop a technique based on CH chemiluminescence EQR in processes. We continuous combustor experimental modeling implementation. An in-depth presentation is given model development digital controller design. Experimental step responses an oxidizer disturbance test are provided validation controller. The designed successful providing settling times less than 4.0 s with maximum overshoot 11.5 %, while simultaneously compensating within ∼1%. With control, 153% increase x emissions prevented response 9% reduction at global near 0.75.
