    • In order to stably operate a boiler using several kinds of solid fuels including depleted ash as fuels, adhesion of ash is suppressed. A calculator (9) preliminarily collects properties of a solid fuel, such as the content rate of ash and the composition of an ash constituent, as data (8). The calculator (9) uses the mix ratio of solid fuels as a parameter and calculates the composition of an ash constituent of the mixed fuels on the basis of the preliminarily measured composition of the ash constituent of each solid fuel. The calculator (9) determines a reference value of the rate of slug by which the ash deposition ratio is reduced on the basis of the relationship between the preliminarily measured ash deposition ratio and the slag ratio. Further, the calculator (9) calculates the mix ratio of each solid fuel using a thermodynamic equilibrium calculation so as to obtain an ash composition in which the slag ratio is not more than the determined reference value. On the basis of the mix ratio of each solid fuel calculated by the calculator (9), the amount of solid fuel dispensed from hoppers (1, 2) is adjusted by a fuel supply amount adjusting device (3). Thus, each solid fuel, the dispensed amount of which has been adjusted, is mixed by a mixer (4) and crushed by a crusher (5) before being supplied to a boiler (7) as a fuel and burned by a burner (6).
    • 为了稳定地运行使用多种固体燃料(包括贫灰的燃料)的锅炉,可以抑制灰分附着。 计算器(9)作为数据(8)预先收集固体燃料的性质,例如灰分的含量率和灰分成分的组成。 计算器(9)使用固体燃料的混合比作为参数,并且基于每种固体燃料的灰分成分的预先测定的组成来计算混合燃料的灰份成分的组成。 计算器(9)基于初步测量的灰分沉积比率和炉渣比之间的关系确定灰分沉积比率降低的渣块的参考值。 此外,计算器(9)使用热力学平衡计算来计算每种固体燃料的混合比,以获得炉渣比不大于所确定的参考值的灰分组成。 基于由计算器(9)计算出的每个固体燃料的混合比,由燃料供给量调节装置(3)调节从料斗(1,2)分配的固体燃料的量。 因此,通过混合器(4)将每个固体燃料(其分配量已调节)通过混合器(4)混合并在被供给到作为燃料的锅炉(7)之前被破碎机(5)破碎并被燃烧器(6 )。
