    Abstract: PROBLEM TO BE SOLVED: To suppress deposition of ash by precisely predicting ash deposition in a heating furnace in which the fuel is a mixture of a metal compound or a metal-containing compound added to a variety of types of solid fuels including bony coal thereby finding an appropriate mixture ratio.SOLUTION: A method for suppressing deposition of ash in a heating furnace comprises: a step (S1) of measuring the composition of the ash component of a plurality of types of solid fuels scheduled for use in a heating furnace and the inorganic composition of a metal compound or a metal-containing compound; a step (S2) of determining a predetermined mixing ratio that provides a composition of an ash component having a slag ratio equal to or less than a standard value, the determination being made on the basis of the composition of the ash component of solid fuel obtained by adding and mixing the metal compound or the metal-containing compound at a plurality of mixture ratios, and on the basis of a slag ratio representing the ratio when a predetermined amount of an ash component precalculated for solid fuel obtained by mixing at the plurality of mixture ratios becomes slag at a predetermined atmospheric temperature and in a predetermined atmospheric gas composition; and a step (S3) of feeding a mixture obtained by adding and mixing the metal compound or the metal-containing compound at a predetermined mixture ratio to the heating furnace as fuel.

    Abstract translation: 要解决的问题：通过精确预测加热炉中的灰分沉积来抑制灰分沉积，其中燃料是添加到各种类型的固体燃料（包括骨骼）的金属化合物或含金属化合物的混合物 从而得到合适的混合比例。 解决方案：一种用于抑制加热炉中灰分沉积的方法，包括：测量计划用于加热炉中的多种类型固体燃料的灰分组成的步骤（S1）和无机组合物 的金属化合物或含金属的化合物; 确定提供炉渣比等于或小于标准值的灰分的组成的预定混合比的步骤（S2），所述确定是基于获得的固体燃料的灰成分的组成 通过以多个混合比例添加和混合金属化合物或含金属化合物，并且基于当比率表示当通过在多个混合物中混合获得的固体燃料预先计算的预定量的灰分成分 混合比在预定的大气温度和预定的气氛气体组成中成为炉渣; 以及将以预定的混合比例将金属化合物或含金属化合物加入并混合得到的混合物作为燃料的步骤（S3）。 版权所有（C）2012，JPO＆INPIT
