Carbon dioxide Boiler radiation heated surface arrangement method.
Background technology
Supercritical carbon dioxide Brayton cycle is one of the most generally acknowledged most potential advanced power cycle.Due to super
Critical carbon dioxide has that energy density is big, heat transfer efficiency high, supercritical carbon dioxide Brayton cycle efficiency power generation
System can reach the efficiency of conventional steam Rankine cycle 700 DEG C in 620 DEG C of temperature ranges, it is not necessary to novel height of redeveloping
Temperature alloy, and equipment size is less than the steam unit of same parameter, application prospect is the best.
The composition feature of China's energy reserves determines coal group of motors and remains China's power industry in coming few decades
Main force, therefore, applies supercritical carbon dioxide Brayton cycle and tallies with the national condition very much at Thermal generation unit, be me
One of technology path of great potential in state's power industry energy-saving and emission-reduction.Send out as supercritical carbon dioxide Brayton cycle fire coal
The nucleus equipment of group of motors, the security relationship of supercritical carbon dioxide boiler, to the stable operation of whole blood circulation, surpasses and faces
The construction cost of boundary's carbon dioxide boiler is also the pith of whole electricity generation system initial cost.Therefore, how by reasonably
Heating surface is arranged, can reduce boiler cost, and can ensure that again the long-term safety of boiler is run is that coal base supercritical carbon dioxide is sent out
One of difficult point of power technology.
Due to carbon dioxide and the difference of water physical property, and the difference of Brayton cycle and Rankine cycle, supercritical dioxy
Change carbon boiler and have significantly difference with traditional supercritical steam boiler.One of them marked difference the most is: dioxy
Changing regenerator heat exchange amount in carbon Brayton cycle very big, high pressure Biological process is heated to the highest temperature and just can enter by the weary gas of turbine
Enter boiler, so the temperature of supercritical carbon dioxide boiler inlet working medium is far above the steam boiler of same parameter.With 25MPa,
As a example by the systematic parameter of 600/600/32 DEG C, the boiler inlet Temperature of Working for the supercritical steam boiler of Rankine cycle is
About 300~320 DEG C, and for the boiler of supercritical carbon dioxide Brayton cycle, its boiler inlet Temperature of Working is about
It it is 500~530 DEG C.Therefore, the tube wall temperature of carbon dioxide Boiler radiation heating surface will be apparently higher than the steam boiler of same parameter.
It addition, in the region that Load Distribution coefficient is high in steam boiler burner hearth, in water-cooling wall, working medium is in large specific heat region, heat exchange system
Number is significantly higher, and in the region that Load Distribution coefficient is higher in the burner hearth of supercritical carbon dioxide boiler, radiation is heated
In face (being equivalent to steam boiler water-cooling wall), working medium works in the region away from large specific heat region, the coefficient of heat transfer only about steam kettle
The 1/2~1/5 of stove water-cooling wall, this temperature mistake being easier to cause supercritical carbon dioxide Boiler radiation heating surface metal pipe-wall
High.Therefore, for the feature of supercritical carbon dioxide boiler, arranged by rational heating surface and reduce radiation heating-surface as far as possible
Tube wall temperature the most necessary.
But the most all rarely have open achievement and patent introduction to relate to solving high parameter supercritical carbon dioxide pot
The method that stove water-cooling wall local wall temperature is too high.
Summary of the invention
The purpose of the present invention is the problem that the supercritical carbon dioxide water screen tube wall temperature solved is too high, it is provided that Yi Zhongchao

Highly, the outlet of main working medium radiation heating-surface is arranged in furnace roof.
Described reheating working medium radiation heating-surface entrance is arranged in furnace bottom, and the outlet of reheating working medium radiation heating-surface is arranged in main work
The lower section of matter radiation heating-surface entrance.
Compared with prior art, the method have the advantages that and present invention employs novel radiation heating-surface cloth
Method of putting heating surface internal to supercritical carbon dioxide boiler furnace is arranged, is arranged by main working medium radiation heating-surface especially
Region above burner region, burner and furnace roof, reheating working medium radiation heating-surface is arranged in the region below burner
And furnace hopper region.In this method for arranging, the radiation heating-surface main working medium radiation that in burner hearth, Temperature of Working is minimum is heated
The entrance in face has been disposed in the burner neighboring area that Load Distribution coefficient in burner hearth is the highest, and Temperature of Working in burner hearth
The outlet section of the highest radiation heating-surface main working medium radiation heating-surface has been disposed in burner hearth Load Distribution coefficient
Low furnace roof region.By using this new method for arranging, effectively reduce high parameter supercritical carbon dioxide boiler main
