Combustibility Evaluation of Heavy Fuel Oil by Modified Fuel Ignitability Analyzer

摘要

FIA (Fuel Ignitability Analyzer) from Fueltech, Norway has already achieved plenty of ignitability evaluation of many kinds of marine diesel fuels over the world. In this study, a total fuel evaluation method on FIA measurement was newly proposed through constructing electronically controlled injection systems. These systems realized near square-shaped injection rate and good repeatability. In the course of the measurement progress, the experimental conditions required to evaluate fuel combustibility became clearer than before. Indexes introduced to evaluate fuel combustibility on the heat release process in FIA successfully determined the troublemaking fuels. Supplementary indexes on simple composition analysis also succeeded in defining the boundary of troublemaking fuels. With all the examinations, combustibility analysis of bunker fuel oil on FIA system brought into reality for the first time.
