Comparison of the mathematical model of pulverized coal burnout with results gained from experimental tests on drop tube

Popis výsledku v původním jazyce

In connection with construction of new supercritical power plants which burn pulverized lignite coal it was started the research of kinetic parameters of coal reserves in Czech Republic. Experimental facility and methodology of pulverized coal termokinetic properties determination with use of mathematical modelling is described in the paper. Thermokinetic properties as a mean for better understanding the nature of combustion process can be determined by experiment using the Drop Tube Test Facility (DTTF) described further in the text. DTTF provides conditions occurring in pulverized coal fired boiler by emulated oxygen concentration, temperature and velocity of reaction gas. The DTTF presented in the paper was build recently at the Energy Research Center. Experimental data acquired from DTTF are planned to be used in mathematical modelling using the code Fluent. The paper describes in detail main differences between used Fluent models of particles combustible fraction and reaction rate
