The combined heat and power generation system can meet requirements of industrial heat users

The utility model discloses a combined heat and power generation system capable of meeting the requirements of industrial heat users. The system comprises a high-pressure cylinder, a medium-pressure cylinder and a low-pressure cylinder of a boiler and a steam turbine, high-pressure bypasses are arranged between the two high-pressure cylinder steam input pipelines and the two high-pressure cylindersteam output pipelines; a reheater outlet of the boiler is connected with an upper steam inlet and a lower steam inlet of the medium-pressure cylinder through two medium-pressure cylinder steam inputpipelines. A steam outlet of the medium-pressure cylinder is connected with a steam inlet of the low-pressure cylinder through a medium-pressure cylinder steam output pipeline; a steam exhaust port of the low-pressure cylinder is connected with an inlet of the condenser through a pipeline, a steam extraction port of the medium-pressure cylinder is connected with an industrial steam extraction pipeline, and low-pressure by
