Method for predicting ash deposition on heated surfaces of a fuel burning combustion vessel

摘要

Apparatus and method are provided for predicting ash deposition in combustion systems. An ash sample is obtained from a selected fuel under controlled conditions. Chemical composition characteristics of the obtained ash sample are identified by a particle-by-particle analysis of the obtained ash sample. An equilibria phase diagram is determined responsive to the identified characteristics of each particle of the obtained ash sample. Then a eutectic temperature of each the particle of the obtained ash sample is determined utilizing the identified equilibria phase diagram.
