Based on an analysis of Deitsh’s formula, which relates the velocity of a gas in an electrostatic precipitator to the magnitude of the overshooting through the apparatus, it is established that the optimal velocity of the flow in an electrostatic precipitator corresponds to the minimum of the second derivative, i.e., 50–60% above the velocity corresponding to the inflection point. It is shown that, depending on the length of the active zone of an electrostatic precipitator, the nonuniformity of the flow may lead to a decrease in the overshooting of 10% and more. On the basis of the results obtained, a gas-distributing lattice mounted in a converging tube that creates nonuniformity in the active zone of the terminal field of the electrostatic precipitator is developed.
