The hot water heating system consists of a heat supply network heater, a heat supply network circulating water pump, a drain pump of the heat supply network heater, a heat supply network water replenishing pump and other equipment and connecting pipelines thereof.
The general heat supply network heater adopts two series connection modes to realize multistage heating so as to fully utilize low-pressure extraction steam and improve the economy of cogeneration. The heater with lower steam extraction pressure is a basic heater, and is always put into operation in the heat supply period, and the water temperature at the outlet of the heater can meet the requirements of the heat supply network under most conditions. The higher pressure of the heating steam is the peak heater, and in a few times of the heating period, the higher pressure steam is added when the outlet water temperature of the basic heater cannot meet the requirement, so that the water temperature is further increased.
And the steam source of the peak heater adopts the higher-pressure extraction steam of a steam turbine or main steam for temperature and pressure reduction and then supply according to the optimal thermalization coefficient and the model selection of the unit. Sometimes spike hot water boilers are provided to meet the demand of spike heat loads, depending on the situation.
The heat source for heating in power plant is extracted from the intermediate pressure cylinder of steam turbine. When the heating season comes, a power plant opens a valve of a heat supply steam extraction pipeline of a generator set, high-quality steam at 230 ℃ is directly conveyed to a heat supply initial station, and heating is started. Therefore, the temperature of the heating steam is much higher than the actual heating hot water temperature, and the large temperature difference is not fully utilized.
