Description
Technical field
The present invention relates to method and the solar energy that proposes in view of the above and the chemical back heating circulatory system (SOLRGT) of fossil energy integrated complementary that a kind of middle low temperature solar thermal energy grade promotes indirectly.
Background technique
Low-temperature solar energy utilized technology and utilizes the chemical back heating power generation technology during at present technology related to the present invention mainly comprised, the state of development and the system features of technology is as follows separately for it:
1) low-temperature solar energy utilizes technology in
In view of the finiteness of fossil energy resource and utilize and produce the seriousness of polluting in the process, developing novel clean energy resources (being the non-carbon energy especially) conversion using becomes an importance of sustainable development.In recent years, solar energy obtains extensive concern with the advantages such as Economy of the spatter property of its unique reserves unlimitedness, the generality that exists, development and use and progressively lifting, becomes one of effective way that solves energy shortage, environmental pollution and greenhouse effect.
Current, the main developing direction of solar utilization technique is that solar photoelectric transforms and photo-thermal transforms, and wherein the solar thermal power generating of photo-thermal conversion is again the most attractive heliotechnics of following twenty or thirty year.But difficult and the low solar energy generation technology cost that causes that waits of energy conversion efficiency is high such as energy storage, be that puzzlement solar thermal power power generation system develops and the great bottleneck of engineering application on a large scale always.Tracing it to its cause, is that solar energy density is low, spatial and temporal distributions is discontinuous on the one hand; On the other hand and what is more important solar energy heating efficient and thermodynamic cycle hot merit conversion efficiency have the contradiction that is difficult to be in harmonious proportion always.Solar energy thermal-power-generating technology and emerging thermochemistry energy conversion technique (as the thermochemistry Conversion of energy system of gas renormalizing etc.) research at present focuses mostly on 900～1200 ℃ transformation of energy of high temperature solar heat and utilization, and mostly is the raising of component capabilities such as high-temperature heat-gathering and thermochemistry conversion and the research and development of relevant new material.High-temperature heat-gathering more than 1000 ℃ is low with equipment complexity, cost of investment height and photo-thermal conversion efficiency invariably to be cost.Comparatively speaking, current 150～350 ℃ middle low-temperature solar energy heat utilization technology obtains large-scale commercial applicationsization with its good solar collecting performance and economic simple heat-collecting devcie.The heat collector of this temperature range adopts the simple optical block of oligomeric light ratio mostly, and solar collecting performance is good, and thermal efficiency generally can reach more than 60%, and has effectively avoided the expensive cost of high temperature solar Conversion of energy system.Yet the temperature of working medium is low more as can be known by the engineering thermodynamics principle, and it is difficult more to realize that heat is changeed merit, at present in the utilization of low-temperature heat quantity still lack effective technology.Relative therewith, conventional energy resource utilizes system through the development in over one hundred year, and technology and technology become better and approaching perfection day by day, has reached more than 1400 ℃ as advanced person's gas turbine working medium temperature.If renewable energy sourcess such as imagination solar energy are able to realize transformation of energy and release in the conventional energy resource system, not only can substitute the consumption of part fossil energy, reduce corresponding pollutant emission, more will greatly improve the renewable energy sources energy and discharge grade and heat commentaries on classics effect rate, alleviate its instability, a discontinuous supply difficult problem simultaneously.The complementary cascade utilization of middle low-temperature solar energy and fossil fuel is expected to provide a brand-brand-new way for solving the clean utilization low and the realization fossil fuel of solar energy transformation efficiency simultaneously.
In the multi-energy complementation system, middle low-temperature solar energy can be mutually integrated with some physics endothermic process in the thermodynamic system (heat is integrated), as evaporation process, heat recovery process; Also can with some endothermic chemical reaction mutually integrated (thermochemistry is integrated), as pyrolytic reaction and reforming reaction etc.The former is as the steam Rankine cycle complementary system of N.Lior and K.Koai proposition, the low-temperature zone working-medium water absorbs about 100 ℃ of solar heat evaporation, the high temperature section combustion of fossil fuel provides heat to make steam superheating, form the coupling utilization of different heat sources in the different temperatures section, solar heat input share is up to 80%, and system thermal efficiency can reach 18%.A kind of middle low-temperature solar energy that the latter such as H.Hong and H.Jin propose and the combined cycle system of fossil fuel thermochemistry complementation, utilize the pyrolysis characteristics of methanol fuel under middle cryogenic conditions, with 200～300 ℃ Driven by Solar Energy methyl alcohol thermal desorption thermal response, generate with H
2With CO be the synthetic gas of main component, be high-grade synthetic gas chemical energy thereby make low-grade conversion of solar energy; Synthetic gas drives the acting of Gas combined cycle, has realized lifting and its efficient conversion in power system of middle low-temperature solar energy grade.In its analysis of cases, solar heat input ratio is 18%, solar electrical energy generation net efficiency and system
Efficient reaches 35% and 60.7% respectively, but turbine blade cooling influence has been ignored in this calculating.
2. utilize the chemical back heating power generation technology
Chemical back heating circulates in the chemical reforming reaction of having introduced fuel on the combustion gas turbine Brayton circuit basis, and when fuel was methane, reaction was mainly:
ΔH＝-41.17kJ/(mol?CO)
When fuel was methyl alcohol, reaction was mainly:
They all are heat absorption reaction, and pressure is more little, temperature is high more, steam/hydrocarbons ratio is high more, and fuel conversion is high more.After fuel is converted into synthetic gas, the calorific value of fuel is improved, compare in original exhaust heat boiler, the regenerator physics callback course to fume afterheat, the chemical back heating circulation has increased in the reformer chemical recovery process to fume afterheat, thereby makes the circulation reach higher efficient.Methane is the main component of rock gas, and is wider than the methyl alcohol application.But methane reforming reaction generally needs the high temperature more than 800 ℃ under nickel-base catalyst, and is not reacting substantially below 330 ℃.Therefore it is infeasible directly providing reaction heat to drive methane reforming reaction with middle low-temperature solar energy.Compare, methyl alcohol can be realized reforming fully at 200～300 ℃.People such as Kesser analog result in 1994 shows: the thermal efficiency that with methane is the basic chemical back heating circulation (cold continuously heat again) of fuel reaches 48.8%, is higher than the steam injection circulation under the identical notes vapour rate.Simultaneously, owing to contain a large amount of water vapors, circuit NO in the synthetic gas
xDischarge quite low, significantly improve than merit.
