Performance Assessment of the Combustion Control Loop

摘要：

Ensuring the optimal state of combustion can lead to maximum energy saving and environment protection. Combustion control has become more important because boiler loads are being varied to meet needs. Although the use of more advanced digital control for automatic combustion provides improved efficiency and stability under carrying loads and eliminates the need for operator inputs during load changes, the assessment of a combustion control system is rarely discussed. This paper is focused on the assessment of a combustion control system scheme against an achievable performance standard of the flue-gas oxygen-content. A procedure is derived based on the minimum variance and the Diophantine decomposition for the feedback control system. The performance bound is computed using the minimum process variances, which depend on the controller. It can assess the performance of the current given controller. The performance of the proposed method is illustrated through a pilot scaled experiment.
