The invention relates to a method and a
system for combining
solar energy thermal power generation with
biomass power generation. When the method is used for generating
electricity in the
daytime (a fine day), one path of
heat transfer oil heated in a heat collection field passes through a
heat exchanger to ensure that counter-flow water is heated up into
superheated steam at the temperature of between 360 and 380 DEG C; and the other path of the
heat transfer oil heated in the heat collection field passes through the
heat exchanger to heat up a fused salt so as to perform
energy storage. The water heated in a
water cooled wall of a
biomass boiler is changed into steam which enters a steam header and a steam-water separator, then is heated to the temperature of between 535 and 545 DDEG C after being sent into a super-heater of the boiler together with the steam at the temperature of between 360 and 380 DEG C, and then is supplied to a
steam turbine to drive a generator to finish the power
generation process. During receiving electric valley adjustment, the
biomass boiler maintains the minimum stable
combustion state. The self power generation of the method and the
system can be used for supplying
electricity to an electric heater in a fused salt heat storage
system to heat the fused salt and perform
secondary energy storage for a fused salt heat tank. During the night, or when a
solar energy condition is not good, the
heat energy stored in the fused salt is released by the
heat exchanger to generate
electricity.
