Simulation of Velocity Field in a Pulverized Coal Fired Boiler

Abstract

This paper selects a 58MW pulverized coal boiler as the research object, three dimensional physical modelling and mathematical modelling are established for the boiler furnace, according to the set of reasonable hypothesis and boundary conditions, the Fluent software is used to simulate the velocity field in the furnace under six operating conditions. Through the numerical simulation results, the optimal operating conditions of this kind of boiler are discussed, which can provide data reference for improving the energy efficiency of small and medium-sized coalfired boilers.
