Description
Technical field
The present invention relates to a kind of solar heat power generation systems in conjunction with combustion gas, Steam Power Circulation electricity generation system, belong to
Solar energy utilization technique field.
Background technique
About tower type solar energy thermal power generation, positive displacement receiver and solar energy-gas combined cycle hair in existing technology
Electricity is summarized as follows.
1, tower-type solar thermal power generating system
Solar energy thermal-power-generating is solar radiant energy to be converted to high temperature heat in a manner of optical focus, then pass through centainly
Device converts heat energy into electric energy.Tower type solar energy thermal power generation uses point focusing technology, also known as centralized solar energy thermal-power-generating system
System.It is equipped with many large-scale reflecting mirror, i.e. heliostat on the place with large area, and every has respective tracing machine
Structure accurately focuses on solar radiation reflection on the receiver at the top of one high tower.The solar radiant energy absorbed by receiver turns
It is changed to thermal energy, thermal energy is retell and is transmitted to working medium, by accumulation of heat link, in input heat power machine, expansion work drives generator, finally
Export electric energy.Tower-type solar thermal power generating system is mainly by optically focused subsystem, collection thermal sub-system, heat accumulation subsystem and power generation subsystem
The part such as system forms.Tower-type solar thermal power generating system started to pay close attention to by common people after the 1980s, existing at present
Many exemplary power stations are in operation or construction.Compared with slot type, dish-style heat generating system, tower-type solar thermal power generating system
With highest focusing ratio, and the heat-collecting temperature of system is high, is also easy to produce high parameter steam, therefore is conducive to improve heat-actuated device effect
Rate.Currently, a main problem of Solar Energy Heat Utilization System is that solar energy has apparent unstability, in cloudy day or evening
On, just without available solar energy, and solar year amount of radiation changes with Four seasons change.Currently, being taken with the solar energy of green
Green energy resource is conveyed to power grid for fossil fuel, it is necessary to be solved the problems, such as solar energy unstability, can just be evaded it to power grid
Impact fluctuation.

According to the working method of heat-absorbing medium in solar receiver, solar receiver can be divided into direct-type and indirect type
Two major classes.Wherein, indirect type solar receiver is mainly characterized by receiver and does not occur to the diabatic process of heat transfer medium too
Positive shadow surface focuses incident solar energy when work and first heats heating surface, after heating surface heating again by wall surface by heat to another
The working medium of side is transmitted.Exposed tubular receiver, positive displacement receiver can be divided by structure type.Exposed tubular receiver
Water, fuse salt, air etc. generally can be used as a heat transfer medium, structure is simple, and it is at low cost, and can receive around tower body
The solar energy focused at any angle by the settled date through field reflection, this mode are conducive to the optimization design of heliostat field layout, mention
The utilization of high solar radiant energy.But the heat absorption round tube of exposed receiver is directly exposed in external environment, in windy weather
Thermal convection losses are larger, thus the thermal efficiency of exposed tubulose heat dump is lower.In order to reduce heat loss, optimize exposed tubulose
Receiver promotes the generation of positive displacement receiver.Positive displacement receiver with exposed tubular receiver is maximum is distinguished as pipe
Beam is arranged in the cavity, and is equipped with a window reception solar radiant energy, so radiation, convection current and reflection loss are all smaller, from
And improve the thermal efficiency.In order to be further reduced heat loss, positive displacement receiver there are also the insulating layer of insulation, reduce with environment it
Between convection losses, in addition, positive displacement receiver also has the heat flux distribution on heat-absorbent surface uniform, absorbing pipe beam pressure drop
It is small, it is small in size, it is light-weight, it is easy to the advantage built and cost is lower.But since solar radiant energy can only enter from daylighting window,
It is required that the solar energy that Jing Chang reflection focuses is by daylighting window, layout and focusing capability to heliostat field have certain limitation and
It is required that unilateral can only be laid out.
3, combined cycle generation system of fuel gas-steam
Gas turbine and its combined cycle generation technology climb up electric industrial scene since the 1950s, but due to working as
When gas turbine and its combined cycle capacity is small, low efficiency, and gas or liquid fuel can only be used, therefore long-term can not be with
Tradition combustion generation technology is mutually equal to.After the 1980s, the single-machine capacity and the thermal efficiency of gas turbine, which have, significantly to be mentioned
The integrated gas-steam combined cycle power plant technology of height, conventional fuel oil and burning natural gas reaches its maturity, in addition the energy in world wide
The structure of resource has great change, and environmental problem becomes increasingly conspicuous, and gas turbine and its combined cycle generating unit are in power train
Status in system is greatly improved, however, fossil fuel resource is non-renewable energy resources, in the present age of energy shortage,
The dependence to non-renewable energy resources is reduced, the direction pollution-free, resource consumption is few new energy is only development is developed and used.
