APPLICATION OF NUMBER SIMULATION STUDY ON COAL COMBUSTION PROCESS IN BOILERS OF THERMAL POWER PLANT

Abstract

The research to improve the efficiency of using Vietnam's non-combustible
anthracite coal is an urgent need. The purpose of the paper is to apply CFD
software to research and evaluate coal powder combustion in coal-fired boilers.
Research results show that the maximum burning temperature in the case of
Hon Gai coal is 16150C. The burning temperature of imported coal is the smallest
but has a large amount of volatile in the coal, which makes for a good flame
ignition. From this result, we can research to find out an appropriate mixing ratio
to efficientlly use domestic coal resources in the country, ensuring improved
reliability in operation.
