本实施例提供的基于超临界二氧化碳闭式循环的热电联产系统使用时具体包括如下步骤：The combined heat and power system based on the supercritical carbon dioxide closed cycle provided by this embodiment specifically includes the following steps when used:
二氧化碳工质首先进入压缩机1升至高压，经回热器2吸收透平4排出工质的热量，再经加热器3从热源吸收热量达到最高温度，然后进入透平4做功推动发电机5工作，透平4排出的工质经回热器2释放部分热量，最后经余热回收器6和预冷器7冷却后进入下一个循环过程。透平4与发电机5之间可通过齿轮变速箱减速，小功率发电机也可直接选用高速发电机，再通过变频装置将发电机输出电能转换成工频。余热回收器6吸收透平4排气的热量送往热用户9，预冷器7的热量释放至冷却塔10，透平4出口设旁路，打开旁路阀8将二氧化碳工质直接进入余热回收器6用于供热。锅炉13的高温排烟的热量通过空气预热器12传递给经空气入口11送入的新空气，从而降低烟气出口15的排烟温度，减少热损失。锅炉13的燃料可采用化石燃料或生物质燃料，由燃料入口14送入。The carbon dioxide working medium first enters the compressor 1 to rise to high pressure, absorbs the heat discharged from the turbine 4 through the regenerator 2, and then absorbs heat from the heat source through the heater 3 to reach the highest temperature, and then enters the turbine 4 to do work to drive the generator 5 Working, the working fluid discharged from the turbine 4 releases part of the heat through the regenerator 2, and finally enters the next cycle process after being cooled by the waste heat recovery device 6 and the precooler 7. The gear box can be used to reduce the speed between the turbine 4 and the generator 5, and the low-power generator can also directly use a high-speed generator, and then convert the output power of the generator into power frequency through a frequency conversion device. Waste heat recoverer 6 absorbs the heat exhausted by turbine 4 and sends it to heat user 9, the heat from pre-cooler 7 is released to cooling tower 10, a bypass is installed at the outlet of turbine 4, and the bypass valve 8 is opened to direct carbon dioxide working medium into the waste heat Recycler 6 is used for heating. The heat of the high-temperature exhaust gas from the boiler 13 is transferred to the fresh air sent through the air inlet 11 through the air preheater 12, thereby reducing the temperature of the exhaust gas at the flue gas outlet 15 and reducing heat loss. The fuel of the boiler 13 can be fossil fuel or biomass fuel, which is sent in through the fuel inlet 14 .
当供电需求下降但供热需求提高时，可以降低预冷器7冷却水流量，从而提高压缩机1入口温度，这样预冷器7入口温度也提高，在工质流量不变的情况下，加热器3总热功率下降，供电功率下降、供热功率提高，能量利用率提高。若供电功率不变，提高供热功率，则可通过旁路将透平4排出的部分工质直接送往余热回收器6，此时加热器3输入热功率上升。When the demand for power supply decreases but the demand for heat supply increases, the cooling water flow rate of the precooler 7 can be reduced, thereby increasing the inlet temperature of the compressor 1, so that the inlet temperature of the precooler 7 is also increased. The total heating power of the device 3 decreases, the power supply power decreases, the heating power increases, and the energy utilization rate increases. If the power supply remains unchanged and the heating power is increased, part of the working fluid discharged from the turbine 4 can be directly sent to the waste heat recovery device 6 through a bypass, and the input heating power of the heater 3 increases at this time.
本热电联产系统的容量为1MWe～100MWe，其循环排放的余热可用于供热、供暖或生活热水，所以非常适合工业区或居民区的供电、供热。The capacity of this combined heat and power system is 1MWe～100MWe, and the waste heat discharged by circulation can be used for heating, heating or domestic hot water, so it is very suitable for power supply and heating in industrial areas or residential areas.
