System and method for carbon capture after combustion of coal-fired power plant
The invention relates to the technical field of coal-fired power generation, and discloses a system and a method for carbon capture after combustion of a coal-fired power plant. The system comprises a boiler, a decarburization reactor, a calcium carbonate storage device, a solar auxiliary regeneration reactor, a calcium oxide storage device, a steam turbine, a condenser and a condensed water heater, flue gas from the boiler enters the decarburization reactor for decarburization; the decarburization reactor, the calcium carbonate storage device, the solar auxiliary regeneration reactor and the calcium oxide storage device are sequentially connected end to end; steam exhausted by the steam turbine after expansion acting enters the condenser to be condensed into water, part of condensed water exchanges heat with decarburized flue gas from the decarburization reactor in the condensed water heater, and the heated condensed water enters the high-temperature heating surface to be heated into steam for expansion acting on the steam turbine. According to the system, efficient utilization of solar energy and CaO chemical energy can be achieved, fossil energy consumption is reduced, and the system is simple.
