Programmed Management of Circulating Fluidized Bed Boiler Fuel and Precise Blending Analysis of Coal Burning
In view of the problem caused by the diversity of coal types existing during fuel operation process such as low blending accuracy of coal as fired,inability to adapt to load changes in the electricity spot market,unit price of standard coal for coal as fired is too high,and low combustion economy,data analysis is carried out through informatization means to perfect process management.Multi process integrated management and multi link data sharing are implemented to achieve programmatic analysis and comparison,comprehensively improving the processing accuracy of coal blending data for precise blending of coal as fired.This study provides data support for the decision-making of coal blending and blending firing,achieving precise control of coal as fired and dynamic optimization of coal storage structure in the coal yard.It enables timely response of daily load response and adjustment at each time period and changes in coal storage structure in the coal yard,and improves the blending level of the unit to economical coal type(inferior coal);Realize the expansion of blended coal type boundary,expand the scope of coal burning procurement,reduce the unit price of standard coal for coal as fired,obtain the optimal unit price of standard coal for coal as received,and achieve over 470 000 tons of blended economic coal type throughout the year.
