Beschreibung
Zusammenfassung:	The utility model discloses a system for fully recycling dead steam of a low-pressure cylinder during peak regulation operation of a combined heat and power generation unit in a heating period, and belongs to the field of combined heat and power generation of steam turbines. A low-temperature buffer hot water area tank, a low-temperature buffer cold water area tank and a high-temperature buffer hot water tank are arranged respectively; heat in the dead steam is exchanged into hot water in a low-temperature buffer hot water area tank through a steam-water heat exchanger, and then heat in the hot water in the low-temperature buffer hot water area tank is exchanged into hot water in a high-temperature buffer hot water tank for storage through a steam-driven lithium bromide heat pump and a water-water heat exchanger; during deep peak regulation, when heat supply network heating steam pumped out of a medium-pressure cylinder is not enough to meet the heat supply requirement of a heat supply network, heat stored in
