In this paper, numerical research of fluidizauon between the tubes in low-power boiler, are presented. In presented flow system, fields of velocity, pressure and concentration was calculated, with assumption steady gas velocity on inlet sections. Calculations was performed with the Euler's method for multiphase flow, on the three-dimensional geometry. Numerical calculation were performed with the Fluent program, where momentum exchange between gas and dispersed phase was taken into consideration. From the considerations it appears that the applied calculation method allows to reproduce a flow of a fluidized bet in the space between the tubes.
