Abstract—Using numerical simulation method to calculate calculation software to posite filter bag’s airflow
conditions of the inner flow field state of a 300MW hybrid electric field including the following steps, as shown in figure 1.
dust collector bag so that the design of gas flow distribution can
meet the demand of posite filter bag. Results from the A. The Numerical Simulation Model
air field test are basically consistent tendency to verify the In 300MW coal-fired boilers generating units, each
reliability of numerical simulation methods. The reliability of this equipped with two dual-chamber posite filter
method and the feasibility of the gas flow distribution design are bags. It is supposed to handle a total volume of flue gas
demonstrated in the study. 1800000m3 / h, as shown in figure 2. Numerical Simulation
is supposed to figure out the gas flow distribution in the
