Beschreibung
Zusammenfassung:	The utility model discloses a heat storage and steam supply system of a coal-fired power generating unit, which comprises a straight condensing unit, the straight condensing unit comprises a boiler, a steam turbine, a condenser, a deaerator, a multi-stage high-pressure heater group and a multi-stage low-pressure heater group, and the steam turbine comprises a high-pressure cylinder, an intermediate-pressure cylinder and a low-pressure cylinder. The multi-stage high-pressure heater set is communicated with a first feed water outlet of the deaerator and a feed water inlet of the boiler, a drain water outlet of the multi-stage high-pressure heater set is communicated with a drain water inlet of the deaerator, and the fused salt heat storage and release system comprises a high-temperature fused salt tank, a low-temperature fused salt tank, a fused salt heat storage unit and a fused salt heat release unit. The fused salt heat storage unit is used for dividing part of steam from a steam outlet of the boiler to heat
