Abstract
The present invention relates to an oxygen-rich steam power generating system which takes metallic solution as a heat exchange medium used for rising temperature, which is provided with an oxidizing furnace, a heat exchanger, the other heat exchanger and an oxygen-rich steam generator, wherein the oxidizing furnace can melt metals, the heat exchanger is arranged between a chimney and the oxidizing furnace, and the other heat exchanger is arranged between the oxidizing furnace and a steam turbine. The present invention has the technical effects that large-capacity steam generated by the heat exchanger and the oxidizing furnace and condensed water from a condensator are all input to the oxygen-rich steam generator, and then are change into oxygen-rich steam to be input to the oxidizing furnace once more under the function of addition of reactants of the oxygen-rich steam generator, so that the metallic solution of the oxygen-rich steam generator quickly acquires high heat and then conducts the high heat to the large-capacity steam in the oxidizing furnace; the large-capacity steam passes through the other heat exchanger which takes circulating molten metal as heat exchange medium to circularly heat the large capacity steam, and finally overheated steam which can drive the steam turbine is output. The present invention has the advantages of novel method of generating overheated steam, higher efficiency of energy conversion, no consumption of fuels and low electricity generating cost and the present invention meets environmental protection requirements.

Description of drawings
Accompanying drawing is a composition structural representation of the present invention.
The specific embodiment
12.5 ten thousand kilowatts is the oxygen-rich steam power-generating system of heat-exchanging medium to heat with the molten steel
This is the oxygen-rich steam power-generating system of heat-exchanging medium to heat with the molten steel, comprise steam turbine 6, generator 7, condenser 8, it is characterized in that being provided with the fusing molten steel oxidation furnace 3, be arranged on a heat exchanger 2 between chimney 1 and the oxidation furnace 3, be arranged on another heat exchanger 5 and oxygen-rich steam generator 12 between oxidation furnace 3 and the steam turbine 6.In fact oxidation furnace 3 is composed in series by a warm oxidation furnace in one and a high-temperature oxydation stove, 300 tons of molten steel total amounts, and about 1700 ℃ of mean temperatures are not less than 1500 ℃ through the temperature after the heat exchange, to reach the requirement that oxygen-rich steam is fully generated heat.In fact oxygen-rich steam generator 12 is made up of the connection in series-parallel of three grade of six cover oxygen-rich steam generator, to reach the needed oxygen-rich steam parameter request of generating.Heat exchanger 2, oxidation furnace 3 waters are supplied with by pre-priming apparatus 11, and the condensed water in the condenser 8 is imported pre-priming apparatus 11 and utilized.Condenser 8 usefulness cooling water Z, pre-priming apparatus 11 usefulness supplementing water W are provided by the water source.The reactant X that oxygen-rich steam generator 12 adds is that the concentrated sulfuric acid, reactant Y are that main component is the fluorite powder of calcirm-fluoride.
Oxidation furnace 3 is under the effect of stand-by electric energy, in advance the steel material in the stove is melted, the high-temperature metal ionized gas input heat exchanger 2 that produces, heat exchanger 2 is actually the metal ion Drechsel system, water is provided by pre-priming apparatus 11, the output of heat exchanger 2 is discharged from chimney 1 with air-introduced machine (not drawing in the accompanying drawing), heat exchanger 2, the flow that produces in the oxidation furnace 3 is 100 tons/hour a steam, all through flow control valve 9 input oxygen-rich steam generators 12, condensed water in the condenser 8 is also imported oxygen-rich steam generator 12 through 18500 tons/hour flow control valve 10, at reactant X, under the effect of Y, oxygen-rich steam generator 12 is automatic heat-exchanger 2 in the future, the steam of oxidation furnace 3 becomes oxygen content and reaches 35～50% oxygen-rich steam, through 13 neutralizations of lime slurry case, after the filtration, re-enter oxidation furnace 3 by the big capacity air compressor 15 of 220 kg/cm high pressures again, make the molten steel in the oxidation furnace 3 obtain high heat fast as thermal source, again high heat is conducted to the big capacity vapor in the oxidation furnace 3, and through the circulation of over-heat-exchanger 5 heating, output at last can drive the superheated vapor of steam turbine 6 works done, and the temperature of this superheated vapor is 500 ℃, flow is 400 tons/hour, pressure is 150 kg/cm.Adopt electromagnetic pump 4 to realize circulating between heat exchanger 5 and oxidation furnace 3 as the molten steel of heat exchange medium, to the big capacity vapor circulation heating in the oxidation furnace 3, the molten steel internal circulating load is 160 tons.Sewage in the oxygen-rich steam generator 12 is discharged in the lump with the condensed water in the condenser 8 after sewage-treatment plant 14 is handled.
Through 10 hours that settings, this operation of electric power system enters stable state to melting molten steel circulation heating, the stand-by electric energy that is used for oxidation furnace 3 molten steel material can be substituted by the output electric energy of this electricity generation system, provides 6000 cubic metres of/hour oxygenerators 16 of oxygen also to stop using by what stand-by electric energy drove to oxidation furnace 3 initial steel liquations.Normal in service electricity generation system account for 10～15% of gross generation from power consumption, the peak accounts for about 20 of gross generation from power consumption in short-term.
