Description

A kind of electricity-generating method and TRT
Technical field
The invention belongs to technical field of power generation, particularly to a kind of electricity-generating method and TRT.
Background technology
In recent years, along with the progress of society and economic greatly developing, electricity has become as in society indispensable One of necessary energy.Electricity is a kind of important strategic energy, is also the secondary energy sources of a kind of high-quality, its cleaning, convenient, utilization Rate is high, is widely used in all trades and professions such as industry, agricultural, military affairs, medical treatment, life with the people, work closely bound up, a state Family per capita household electricity consumption number indicate this country level of economic development and living standards of the people, although Chinese people All power consumption is close to world average level, but only Systems in Certain Developed Countries 1/4～1/5, gap is obvious, and the demand of electricity is potential Market is the hugest.
Although electric energy high-quality, cleaning, but it is difficult to store, and need after all primary energy (fossil energy, water energy, wind energy, Luminous energy, biomass energy) convert and just can obtain, wind energy, luminous energy etc. are good nature regenerative resource, are preferably generatings Primary energy, country subsidizes, and encourages to use, but owing to geographical constraints and timeliness limit, have extremely strong intermittence, Its power is unstable, and generating dutation is unstable, and electrical network is produced enormous impact, and can carefully generate electricity by way of merging two or more grid systems is very few, by industry Interior address is rubbish electricity, so there is large-scale " abandon wind, abandon light " phenomenon.
China the most still generates electricity based on fossil energy (firepower), and according to statistics to the end of the year 2012, the whole nation total installed capacity of electricity holds Amount breaks through 1,100,000,000 kilowatts, and wherein thermoelectricity installed capacity reaches 8.1917 hundred million kilowatts, accounts for the 71.5% of total installation of generating capacity；Water power 2.4890 hundred million kilowatts, account for the 21.7% of whole installed capacity；Nuclear power 12,570,000 kilowatts, grid connected wind power 60,830,000 kilowatts, the grid-connected sun Can generate electricity 3,280,000 kilowatts, three sums account for the 6.8% of total installation of generating capacity.As can be seen here, thermal power plant is either to national economy Development, or the raising of living standards of the people, all play significant role.
Thermal power plant drawback is exactly: contaminated air, polluted source, the coal resources of consuming preciousness.Environmental pollution is fire The a great problem matter of great urgency solved is badly in need of in power generating, from July 1st, 2014, active service coal-burning power plant is come into effect " thermal power plant Atmosphere pollutants emission standards " (GB13223-2011)；Only 2014, coal-burning power plant's pollutant emission is required just there are three changes Changing, cause a large amount of coal-burning power plants environmental protection facility to repeat transformation, marginal cost increases；Within 2014, electric power Air Pollutants Emissions is big Width declines, and electric power flue dust, sulfur dioxide, nitrogen oxide emission are down to 980,000 tons, 6,200,000 tons, about 6,200,000 tons respectively, real The such data in border or severe contamination atmospheric environment.
By analysis, having developed the renewable energy power generations such as solar energy, resolved electrical power storage, the storage of electricity is permissible In a disguised form producing hydrogen by electrolysis water to solve, when generating electricity peak, substantial amounts of electric energy is used for being electrolysed water generation hydrogen, by hydrogen Store, when there is no light (wind) or at light (wind) generation deficiency, hydrogen is carried out conversion by combustion engine and produces electric energy, enter Automatic control regulation joint reaches balance movement, it is achieved secure internet connection, external steady electricity supply, and such wind-powered electricity generation, photoelectricity are the most no longer rubbish electricity.
But, the bottleneck that real restriction hydrogen generates electricity on a large scale, not cost is high, in fact present fossil energy rapid rise of price, The cost of hydrogen is not the most to receive, and real bottleneck is storage and the safety of hydrogen, the most not yet has perfect solution Certainly scheme.Metal Hydrogen Brittleness Phenomena almost hydrogen life, had both possessed metal solubility, had possessed again nonmetal solubility, all-pervasive Hydrogen, really be difficult to long-term safety store on a large scale.This is a global difficult problem.And hydrogen is in the air of 20 degrees Celsius Explosion limit scope be terrified 4%～74.2%, for the maximum magnitude of all common fuel gas, the huge difference of safety is incomparable. This is only and dare not be the arch-criminal of the energy by large-scale use hydrogen.
