Road, is also associated with the vapours output pipe after the heating of deoxygenation all the way, the vapours output pipe is by connection one plate heat exchange
A heat storage water tank is connected after device；With the plate heat exchanger and being connected to the heat accumulation water-delivery pump that valve all the way connects, led to by the heat accumulation water-delivery pump
Cross valve and Boiler High Pressure feed pump connection thermal power plant boiler.
As preferred：Inflow temperature in described normal temperature inlet pipeline is heated at 15-25 DEG C, and by high pressure deoxygenation
140-160 DEG C of steam streams are formed after device, in the plate heat exchanger, described steam stream is with being connected to normal temperature inlet pipeline
Normal-temperature water carry out heat exchange type enter heat storage water tank into the hot water for being not less than 95 DEG C；The capacity of described heat storage water tank is with peak
Period is exhausted on the basis of storage hot water.
A kind of to carry out tide heat supply method using described tide heat reservoir, described tide heat supply method is：
Low-valley interval：The high-temperature steam largely drawn from steam turbine is introduced into high pressure by valve control by steam heating pipeline to remove
Oxygen heater, the high-temperature steam hot-fluid after high pressure deaerating heater sends into heat storage water tank after plate heat exchanger and carries out heat
The storage of energy；
Peak period：Hot water in heat storage water tank is conveyed into heat by valve control and Boiler High Pressure feed pump to thermal power plant boiler
Water, now, by steam heating pipeline by the high-temperature steam largely drawn from steam turbine by valve control direct heating to user.
The invention belongs to improvements over the prior art, it has structure composition rationally, using easy to operate, can improve heat supply
The heat capacity of equipment, improves the thermal efficiency, the features such as energy-saving obvious.
