The type of air entry distribution is essential in the formation of hydrodynamic structures of fluidized bed. The present study is aimed to form a hydrodynamic structure of fluidized bed optimal for burning low-grade solids fuels. In order to determine the uniformity of the fluidized bed in the bed heat exchange rate between the bed and a heat exchange member immersed therein was measured. At a first approximation, heat exchange with the member immersed into the bed imitates heat exchange between the fluidized bed and a fuel particle. It is allowed to determine that an optimal hydrodynamic structure of the bed can be formed by using a lattice supplying the major portion of air near the furnace wall. The above conclusion was confirmed by experiments using a real furnace with a fluidized bed.
