itself to changing process situations like e. g. changes in coal qualities, mill wear, wall slagging, soot blowing etc. - ensures compliance with the limit values for NO x and ammonia slip in all load cases (10 percent - 100 percent). The combination of primary NO x reduction with advanced combustion optimization plus Online-CFD as
Minimum fly ash carbon content is achievable by implementing a comprehensive approach to combustion optimization. Actual values of carbon in ash or L.O.I. (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.
Cut out oil support at higher loads where coal flame is stable as oil preferentially deplete o. 2. in the area and reduces 'o. 2 ' for coal particles to burn. Check coal property and tune combustion. Keep boiler heat transfer surface clean so that losses can be reduced thus reducing the coal input. Methods to reduce . unburnt. carbon loss

Based on Optimized Furnace Combustion Combustion Optimization is a pre-requisite 1575 1675 1775 1875 1975 2075 2175 10 25 40 55 70 85 100 percent load(%) furnace exit gas temperature(°F) 2175 The FEGT should be on the curve PROVIDING that the mills, combustion airflows and burner belt performance is optimized.
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 real-time load was unpredictable and the coal utilization rate was inconsistent of each bunker.
