Description
(1) technical field
The present invention relates to power domain, a kind of specifically thermal power generation installation of solar energy that fully utilizes the electrical production mode of solar energy and two kinds of energy generatings of fuel.
(2) background technique
At present, the electrical production of China is based on hydroelectric power, thermal power generation and nuclear power, and wherein, topmost generation mode is thermal power generation, approximately will account for 80% of China's generating total amount.
Thermal power generation adopts fuel boiler that water is heated, and makes water become steam, enters high-pressure chamber, and promotes the generating of turbo machine rotation cutting magnetic line by the high pressure steam that discharges high-pressure chamber.The efficient of this generating is lower, even the non-large-scaled unit of present comparative maturity, the generating efficiency of fuel only is about 40% also, and along with the rise in price of coal equal energy source goods and materials, economic benefit also will be downward trend year by year.Because the performance of this kind equipment is limited, does not also have what mode significantly to improve the fuel generating efficiency of these equipment at present.
(3) summary of the invention
The goal of the invention of solar energy thermal power generation principle of the present invention is to provide a kind of low operating cost, general thermal power generation improved procedure, improves the thermal power generation installation of solar energy of fuel generating efficiency.
The object of the present invention is achieved like this: it comprises thermal power generation boiler 4, turbo machine 6, generator set 7, condenser 8, solar energy vacuum tube Heater group l, high temperature circulation pond 3 and low temperature circulatory pool 12, condenser 8 links to each other with low temperature circulatory pool 12 with solar energy vacuum tube Heater group 1 by pipeline, low temperature circulatory pool 12 links to each other with solar energy vacuum tube Heater group 1 by pipeline, solar energy vacuum tube Heater group 1 links to each other with high temperature circulation pond 3 by pipeline, high temperature circulation pond 3 links to each other with thermal power generation boiler 4 by pipeline, and pipeline is provided with control valve.
The present invention combines solar energy and thermal power generation, wherein, condenser reduces water temperature and forms low-pressure water, make it and enter between the high temperature and high pressure steam of turbo machine 6 and form pressure reduction, improve turbine rotor efficient, while solar energy vacuum tube Heater group 1 obtains low temperature water from low temperature circulatory pool 12 and heats, the heating back forms normal temperature and pressure boiling water, normal temperature and pressure boiling water is sent into high temperature circulation pond 3,3 introducing normal temperature and pressure boiling water further heat thermal power generation boiler 4 from the high temperature circulation pond, produce high temperature and high pressure steam, high temperature and high pressure steam promotes turbo machine 6 runnings again and drives generator set 7 generatings.In addition, condenser cools off the steam that enters condenser by extraneous cold water, forms low-temperature circulating water and enters low temperature circulatory pool 12, after the cold water performance cooling effect, generate the additional water that heats up, replenish a water part and send into low temperature circulatory pool 12, as replenishing of circulating water loss.When solar energy vacuum tube Heater group 1 once more when low temperature circulatory pool 12 is obtained low temperature water and is heated, just formed the hot machine circulation of solar energy firepower combination electricity generating principle.When needs are closed the solar energy heating function, can from condenser 8, send low-temperature circulating water to deliver to high temperature circulation pond 3 by cut-off, realize traditional thermo-mechanical power generation.Low temperature circulatory pool 12 interacts with high temperature circulation pond 3 among the present invention, when being ended, the process of solar energy heating do not influence the carrying out of the hot machine flow process of thermal power generation, the compound mode of heating that adopts solar energy to combine with the fuel mode of heating simultaneously makes water vapor, saved the fuel that consumes in the power generation process greatly, for technical field of power generation has been started new situation.
The principle of the solar energy thermal power generation that the present invention adopts is disclosed to be a kind of improved procedure of the hot machine principle of common thermal power generation.The hot machine principle of its flow process and common thermal power generation is approaching.Both differences exist: the mode of heating that makes water vapor.Common thermal power generation principle adopts the fuel mode of heating to make water vapor; The compound mode of heating that solar energy thermal power generation principle adopts solar energy to combine with the fuel mode of heating makes water vapor.Adopt this improved thermal power generation principle, the process of heating of water heats a kind of mode, a step by the fuel in past to be finished, and is improved to dual mode, two steps and finishes, for technical field of power generation has been started new situation.
The beneficial effect of thermal power generation installation of solar energy of the present invention is: the fuel consumption that can reduce thermal power generation.Present principles does not change the conversion efficiency of thermoelectric of former hot machine, and adopts the solar energy mode to preheat to circulating water, has in fact saved the fuel energy that heats up and consume in the temperature range that makes water, reaches the purpose of design of fuel saving of the present invention.In the process of tentatively heating, the temperature and pressure of water is not high, and adopt the solar energy heating mode this moment is feasible.
