The boiler steam production efficiency at China’s Guohua Ninghai Power Plant is controlled by adjusting a precise flow of blended primary ambient air and pre-heated air which flow from separate ducts. Each of the duct air flows are controlled by louvered dampers located inside the ducts. The preheated air is blended with the primary ambient air and flows into the coal mills, and afterwards the boiler. Accurate, responsive and reliable air flow measurement is critical to the automated control of the dampers and the efficiency of the boiler, which also ensures safe operation of the boiler and reduces plant operation energy costs.
