Abstract

Oxygen-blown ICC is one of the power generation technologies that can achieve both power generation and CO₂ capture with high efficiency. In order to improve this operability, we have developed a thermal and material balance model that can predict the gasification characteristics of coal and biomass suitable for oxygen-blown gasifiers. The accuracy of the char generation prediction formula was confirmed by applying three types of char generation prediction formulas to this model and comparing them with the operation data of a small gasifier (10t/day) and a large gasifier (150t/day).
