For extracting the electric compression heat pump waste heat recovery heating system of electric power plant circulating water waste heat.
Background technology
On September 13rd, 2016,《Renewable Energy Law》Implement in the forum of ten anniversaries National Energy Board's new energy with can be again
Raw Energy Division director Zhu Ming proposes the Renewable Energy Development target in " the 13 " period tentatively established, to the year two thousand twenty,
Strive that photovoltaic generation reaches 1.5 hundred million kilowatts, photo-thermal power generation reaches 5,000,000 kilowatts, and wind-powered electricity generation reaches 2.5 hundred million kilowatts；Regenerative resource
Power supply will be more than 20% in the generator installation ratio of the year two thousand twenty.I.e. based on " 13 " period wind-powered electricity generation and solar energy power generating
Renewable Energy Development turns into the emphasis of China's energy development.
Quick increased regenerative resource installation amount brings nearly remote two problems for the development of China's power industry,
That is abandoning wind at high proportion, abandoning optical issue and following power network is to the regulation problem of the grid-connected consumption of large scale regenerative resource at this stage.
2015, although the ratio that the wind-powered electricity generation in China and photovoltaic generation total amount account for gross generation only has 4% or so, multiple regional faces
Face very severe renewable energy power generation consumption problem, abandon wind, abandon optical issue protrusion, cause huge loss and negative shadow
Ring；According to statistics by the end of in first six months, 2016, China abandons wind rate and reaches 21%；Wind is abandoned in some areas, and to abandon light more serious, with
Exemplified by Gansu, abandon wind rate 39% within 2015, abandon light rate 31%.
China is electricity consumption big country, and electric power installed capacity, which has surmounted the U.S. in 2013, turns into global first big country (electricity then
Power installed capacity is 12.47 hundred million kilowatts；The installation scale of wind-powered electricity generation and photovoltaic generation ranks the first in the world).For power supply architecture, fire
Electricity is not only the most important power generating source in China；And in the relatively low situation of the peaking power source ratio such as water-storage, gas-fired station
Under, thermoelectricity will also undertake power peak regulation task；In addition heat supply task is also taken into account in heating period thermoelectricity.The multiple player of thermoelectricity makes
It is difficult to play Peak Load Adjustment.With structure adjustment of power source, renewable energy power generation constant increases, and necessarily causes in " three Norths "
Regional warm season peak regulation scarcity of resources, the then grid-connected consumption to extensive regenerative resource cause certain difficulty.Therefore, strengthen
The peak modulation capacity in thermal power plant, by coal group of motors from providing the entity power supply of electric power, electricity to providing firm power, peak regulation
The basic power source transition of fm capacity seems most important.
In addition, the cold end loss in thermal power plant is the maximum loss of electric power therrmodynamic system.According to statistics, the steam discharge of steam turbine
Loss can account for more than the 39% of fuel gross calorific power.Turbine discharge loss is the used heat of discharge for thermal power plant,
But for low-grade constructure heating, really huge energy loss.So if cooling circulating water taken away this
Part turbine discharge heat can depth recycle and be used for town dweller's heat supply, this will not only greatly improve the energy of power plant
Source utilization ratio, increase area of heat-supply service, additionally it is possible to huge economic benefit and social benefit are brought to power plant.
