The secondary optimization was implemented by adjusting the outputs of different mills, then the blend was changed to accurate ratio. Furthermore, since the existence of coal bunker, it made a time lag from coal discharge to combustion, meanwhile, the realtime load was unpredictable and the coal utilization rate was inconsistent of each bunker.
This is all controlled by the coal mill or pulveriser, and its associated feeder equipment. Operation of the coal mill can affect the ramp rate of the power station and its ability to handle rapid changes in output. For coalfired power plants, the response time of the coal mills is critical for the overall reaction time to changing demand.
The paper presents a novel concept and method of coal combustion process analysis using flame scanners supervision system. The combustion process analysis and diagnostic has a crucial influence on boiler effectiveness, especially in high variance of load demand, which is nowadays a top challenge for coalfired power plants.

CCE has been awarded blanket contracts from multiple large utilities located in the Midwest. These contracts include boiler performance testing, pulverizer testing with coal flow balancing, air flow testing, combustion tuning, and SCR AIG tuning.
include maintenance status of the combustion equipment (burners, mills, and dampers), degree of process automation, operating practices, and limitations imposed by environmental regulations. Therefore, each combustion optimization project is very much sitespecific.
(3) As applicable, observe the damper operations as a function of mill and/or cyclone loadings, cyclone and pulverizer coal feeder loadings, or other pulverizer and coal mill performance parameters, making adjustments and effecting repair to dampers, controls, mills, pulverizers, cyclones, and sensors;
Minimum fly ash carbon content is achievable by implementing a comprehensive approach to combustion optimization. Actual values of carbon in ash or (Loss on Ignition) can vary widely, dependent on coal ash content, coal reactivity, coal volatile matter, boiler residence time and numerous boiler, as well as fuel burning equipment specifics.
