Abstract:
1. A method for suppressing adhesion of ash in a boiler, comprising: a step of determining a mix ratio of a plurality of types of fixed fuels, based on a composition of an ash constituent preliminarily measured for each of the plurality of types of solid fuels, and based on a slag ratio that is calculated for each of the plurality of types of solid fuels, and indicates a ratio of a part of a specific amount of an ash constituent which becomes slag under a predetermined ambient temperature and a predetermined ambient gas composition, so that slag ratios in the boiler are not more than reference values; and a step of mixing the plurality of types of solid fuels based on the mix ratio of the plurality of types of fixed fuels, and supplying the mixture as a fuel to the boiler.
