The invention belongs to the generating equipment scope and in particular relates to a mixed
heat power generating
system with a
paraboloid groove type
solar heat collector to assist a
coal burning boiler. A
solar heat collector field is connected with a
feed pump and a second or a third high-pressure heater; a condenser, an extraction pump, a low-pressure heater, a
deaerator, the
feed pump, the high-pressure heater, the
coal burning boiler and a
steam turbine are connected in series in turn; and the
steam turbine drives a
dynamo and discharges steam to the condenser.
Condensed water flows out from the condenser and is heated up and pressurized up by a the low-pressure heater, deoxidized by the
deaerator, fed with water by a leading-out part of the
feed pump and enters the
solar heat collector field for heat absorption; after reaching a
stream drawing parameter of a certain stage high-pressure heater, the
condensed water returns and joins the drawing gas of the corresponding stage heater; the other part of feeding water enters the
coal burning boiler through the high-pressure heater and becomes steam with high temperature and
high pressure; and the steam enters the
stream turbine, applies work and flows into the condenser to complete a
thermodynamic cycle. The mixed
heat power generating
system with the
paraboloid groove type solar heat collector to assist the coal burning boiler reduces coal consumption of a coal burning unit, improves
thermal efficiency of the solar
heat power generation and reduces the investment on the simple
paraboloid groove type solar heat power generation.
