The object of study in this article is presented in the form of an inertial-vacuum dust collector (IVDC). There are two types of IVDC: first generation and second generation. The first experiment was conducted in 2009, and the second in 2018. The plants consider similar principles of dust collection. The purpose of this article is to compare the results of a full-scale experiment conducted on a second-generation inertia-vacuum dust collector at the Omsk TPP-4 station and the data of a numerical experiment calculated in ANSYS CFX. After the initial calculations, adjustments were made to the boundary conditions. The data obtained in the course of a numerical experiment with specified boundary conditions are in good agreement with the full-scale experiment. Measurement schemes and graphical dependences of the degree of capture efficiency on the geometric characteristics of the ash collector are presented.
