More and more power plant through the nozzle to atomize chemical water, but the arrangement of the nozzles did not have a reasonable plan. In this paper based on the computational fluid dynamics of two-phase flow theory, according to the geometry of300MW unit condenser throat to built the geometric model, then use the GAMBIT software to form of the computational grid. The discrete phase model and the κ-ε turbulent model were used to construct the numerical model for the throat of a condenser. Using FLUENT software carries on the corresponding numerical calculation to the numerical model for the throat of a condenser. Analysis of the throat of a condenser on the base of the numerical model, simulation of injection pressure, nozzle diameter, jet angle, water flow and throat entrance velocity of steam and other factors on the flow field in condenser throat. Simulation and analysis the effection of the coupled heat transfer which under the different arrangement of nozzles, to get the conclusion that correctly and rigorous numerical analysis on the condenser water atomizing system has an important guiding significance, then according to the simulation results of the atomizing nozzle to layout reasonablely.
