Abstract

In this paper, Hesi Wulai lignite, Shaltala lignite and Shanxi Gepu bituminous coal were selected to participate in experimental study in a 350MW supercritical boiler, the design coal of which is lignite. This study investigates the pyrolysis behavior of ten kinds of blended coal using thermogravimetric analysis at a heating rate of 20 /min to determine mass loss rates and firing temperature as a function of blend composition. This study also investigates the optimal blending ratio using the multi-objective fuzzy decision-making model with the coal price and sulfur content of blended coal being taken as objective functions. It was proposed that the optimal blending ratio of the Hesheger Ula lignite, Salta pull lignite and Shanxi Gepu bituminous coal was (4: 4: 3).
