Abstract

The invention discloses a multifunctional energy system. In the system, coal and natural gases simultaneously enter a reforming reactor, and the coal fires in the reforming reactor to drive the reforming reaction of natural gases, which generates synthetic gases of H2 and CO; the synthetic gases pass through a shift converter to convert CO into CO2, and then enter a pressure swing adsorption device(PSA) for preparing hydrogen gases; tail gases generated in the PSA device are sent to a CO2 separator to separate out a majority of CO2, and then compressed and cooled to become liquid CO2, which is convenient for transportation and storage; hydrogen rich fuel gases remained after the separation of CO2 are sent to a generating set, and high-temperature flue gases enter a waste heat recovery and a steam generation device, and the flue gases, the waste heat of which is recovered, are discharged in air; the flue gases discharged by a dual fuel reformer are also enter the waste heat recovery and steam generation device for recovering the waste heat, and then enter the CO2 separator to separate CO2 contained in flue gases; purified CO2 is compressed and liquefied, and finally the flue gases are discharged in air. The multifunctional energy system has the advantages of improving the utilization rate of the fuel and realizing the control and recovery of CO2 with zero energy consumption.
