Numerical Simulation on Flow Field of Coal-Fired Power Plant Flue Pipe with Inner Supports

Abstract:

The flow distribution in flue pipes has a great effect on collection efficiency.Gas pressure and velocity distribution in flue pipes upstream electrostatic precipitator were investigated using computational fluid dynamics (CFD) in this paper. The flue pipe model was established on the basis of standard straight and bended flue pipe which were widely used in engineering. And the availability of numerical simulation model was verified by comparing the empirical curve and the numerical simulation results of a common pipe bend without inner supports. In the same condition, these two flue pipes were simulated. The result shows that inner supports have great impact on flue pipe and the values of the pressure drops are closely linked to airflow directions. These results can provide theoretical basis and method guidance for design of inner support.
