Abstract

The mixture fraction/probability density function (PDF) model and eddy break up (EBU) model were used to simulate the combustion in a 200MW foursquare tangential circle boiler, calculating the flue gas velocity field, temperature field and combustion product concentration distribution in the furnace. The calculated outlet oxygen concentration and coal burning rate via EBU model were 2.7% and 98.38%, and were 3.0% and 98.82% for PDF model; the convergence time of EBU model is half of PDF model.
