“…As shown in Figure , the Aspen Plus is used to construct the simulation model of the saturated flue gas waste heat recovery system. , The simulation flow medium includes lithium bromide solution, water, and flue gas in the model. As shown in the following Table , the generator in the absorption heat pump is replaced by the heater and flash modules, the condenser in the absorption heat pump is replaced by a condenser module, the throttle in the absorption heat pump is replaced by throttle1 module, the evaporator in the absorption heat pump is replaced by the HeatX module, and the absorber in the absorption heat pump is replaced by mixer and heater modules.…”
