FIELD: machine engineering.
SUBSTANCE: invention relates to reactor structures comprising a circulating fluidized layer and one or more bubbling fluidized layers, and also to non-mechanical valves to selectively control the flow of solid phase particles moving between zones with a slow bubbling layer and zones with highly fluidized circulating layers. The non-mechanical valve comprises a partition wall separating the two sections, an opening in the partition wall, independently adjustable fluidizing means arranged upstream or downstream relative to the opening, connected to the fluidizing medium supplying means and configured to selectively control the flow of the particulate solid phase passing through the opening, collectors connected to independently controlled fluidizing means, enabling the collection of any solid phase particles entering the fluidizing means so that the accumulated solid phase does not interfere with the supply of the fluidizing medium to the fluidizing means, and independently controlled solid phase removal means located upstream or downstream relative to the opening, designed to remove the solid phase and agglomerates.
EFFECT: improved control of local fluidization and operation of non-mechanical valves.
