Coal quality analysis and thermogravimetric analysis of No.6 boiler of Fengcheng Phase Ⅱ Power Plant were researched

and 12 different sub-warehouses blending programs for the representative coal were selected

and the boiler thermal efficiency tests were carried out.The impacts of the boiler fly ash combustible

the slag combustible

smoke damage in the trial to the boilers efficiency were analyzed

the optimum co-firing of coal blending were advanced

and the scientific basis for the boiler combustion optimization adjustment were provided.
