Abstract: Numerical modeling of large sieam boilers by means of modularization concept is investigated in the present paper. The 300 MWt (420t/h steam) drum type, natural circulation, coalfired steam boiler is divided into fifteen modules, each one containing basic configurations of heat exchangers. The goal of numerical research accomplished in this paper is to predict steam boiler behavior (by means of live steam parameters and overall efficiency) when the low heating value of coal fuel fluctuate in a range of 15% from mean value.
