Chemical Equilibrium Prediction of release inorganic species during high temperature combustion and gasification of biomass, hard and soft Chinese coal by FactSage

摘要

The lack of fossil fuel resources and huge demand of Energy next 30 years is required to installation of additional power plant to meet the crises of power generation, recently coal based combined power generation system are under development with aim to increase the efficiency of coal combustion and gasification but it requires a reliable gas cleaning to provide the gas turbines and prevent them to hot corrosion caused by Na-,CI- and S-containing species, unfortunately these species are released during thermal conversion process but major depends on the condition of thermal utilization process and the composition of minor elements of coal moreover these species are highly volatile and lead to several problem of fouling, slagging and corrosion when they reach the colder part of plant. Therefore the comprehensive knowledge is required prior to carry out experiment.
