FIELD: construction, pipeline.
SUBSTANCE: invention pertains to power field. Operational method of a reactor with fluidised bed contains furnace with outlet opening for exhaust gas and separator for separation of solid particles from exhaust gas, having inlet opening connected with the gas outlet opening by means of exhaust gas pipeline, gas outlet opening connected with the exhaust gas pipeline and outlet opening for solid particles connected with return pipeline for recirculation of solid particles back into the furnace. Method consists of the following stages: cross-over pipeline is arranged around the separator for separation of particles and throughput of the partial flow of the exhaust gas and carried away solid particles through cross-over pipeline from the upper part of the furnace into the pipeline for exhaust gas for increasing solid particles content in the exhaust gas after the separator for particles separation. Method additionally includes a stage of adjustment of the exhaust gas flow in the cross-over pipeline for regulation of the number of solid particles sent by-passing the solid particles separator. Exhaust gas flow in the cross-over pipeline is adjusted by supply of excess gas into the cross-over pipeline. Exhaust gas flow in the cross-over pipeline is adjusted by control valve set inside the cross-over pipeline.
EFFECT: reduced hazardous emissions in to the atmosphere and decreased capital costs.
