Against five commonly used coals in Jiangxi Xinchang Power Plant

three was selected to be applied in blended coal combustion.By thermogravimetric analysis

combustion characteristics of the mixture of the above three coal were analyzed.During the field blended coal combustion experiment

four load points were selected

seven coal mixtures were prepared and fourteen ways of conveying the coal to furnace were developed.Moreover

under each coal blending scheme

the optimal oxygen content was obtained by oxygen varying test

to ascertain the optimal coal blending scheme.At last

by measuring the boiler efficiency in different operating conditions

the recommended coal conveying scheme was obtained.
