Modelling of Effects of Operating Conditions and Coal Reactivity on Temperature of Burning Particles in Fluidized Bed Combustion
Original language description
Two simplified models for estimation of temperatures of smaller, low ash char particles and bigger high ash char particles burning in fluidized bed (FB) have been formulated and solved in our study. For smaller, low ash char particles constant temperature across char particles and for bigger particles radial temperature profile was assumed. Results of the model solutions have shown that the temperature of burning char particles increases with increasing oxygen concentration in flue gas, with increasingoperating pressure, decreasing char particle size and increasing reactivity of the char.
