The overall coal property evaluation is discussed in dynamical system, which linksclosely with the parameters of coal burning quality, slag-bonding characteristic and operating characteristic. The singal coall property index is avaluble resolution factor in showing coal propertybut it cannot overall reflect the coal property extinctly in dynamical system. In the modern engineeting application, the intrinsic property of coal always combines with concrete facilitics and operating conditions, which exposes the vulncrability of tile singal discriminant parameter. In orderto improve the resolving a...
