METHOD AND PLANT TO BURN IN LOOP REACTOR WITH INDEPENDENT CONTROL OF SOLID SUBSTANCES CIRCULATION Russian patent published in 2014 - IPC F23C10/10 F23C99/00 

FIELD: heating.

SUBSTANCE: invention relates to burning in a loop reactor. The method to burn in a loop reactor at least one type of hydrocarbon raw materials in at least one reaction recovery zone (i) and at least in one oxidation zone (i+1), representing separate fluidised layers, in which circulation of solid particles of active mass between each reaction zone or a part of reaction zones is controlled with the help of one or several non-mechanical valves, each comprising a substantially vertical section of a channel, a substantially horizontal section of a channel and an elbow connecting both sections, with transportation of solid particles between two serial reaction zones by means of the following operations: introduction of solid particles arriving from the reaction zone (i) or (i+1) via an upper end of the substantially vertical section of the channel of the specified valve; injection of control gas with the specified aeration flow at the inlet of the elbow of the specified valve; control of conditions of differential pressure at the borders of non-mechanical valve (valves) for adjustment of the flow of solid particles in the substantially horizontal section of the channel of the specified valve depending on the aeration flow, supply of the serial reaction zone (i+1) or (i) of the loop with solid particles that leave the non-mechanical valve or non-mechanical valves.

EFFECT: invention makes it possible to control circulation of solid substances in a loop reactor regardless of gas flow values.
