Technical field
The utility model relates to boiler, further is meant the condensed type combustion gas uphole steam generator.
Background technology
Along with the continuous expansion of thickened oil recovery scale in the world wide, the exploitation via steam injection viscous crude more and more causes people's attention as a kind of maturation process, and along with the rise of energy prices, the power-saving technology of uphole steam generator is upgraded becomes trend of the times.Uphole steam generator commonly used now all adopts the direct current cooker form, mainly comprises combustion system, radiant section, changeover portion, convection section, water-water heat exchanger and chimney.Because uphole steam generator fuel mainly is residual oil, crude oil and natural gas, injection boiler all is designed to oil-gas two-way, for reducing the cold end corrosion of flue gas to pipe; The water that gets into convection section all is heated to more than 100 ℃ through water-water heat exchanger earlier, adds when burning residual oil, crude oil the seriously polluted and easy-clear not of heating surface pipe, causes exhaust gas temperature high (generally more than 200 ℃); When particularly being fuel with the natural gas again; Flue gas is when contaminated pipe conducts heat, and heat-transfer effect is poor, and the sensible heat of flue gas and latent heat are all wasted very serious; The injection boiler heat loss due to exhaust gas is big, and the thermal efficiency is low.
Summary of the invention
The technical problem that the utility model will solve is; Deficiency to prior art; Having proposed is the condensed type combustion gas uphole steam generator of fuel with the natural gas, through reducing the exhaust gas temperature of injection boiler, rationally reclaims sensible heat and latent heat in the flue gas; Reduce heat loss due to exhaust gas, improve the thermal efficiency of boiler.
The technical scheme that the utility model adopts does; A kind of condensed type combustion gas uphole steam generator; Comprise combustion system, be provided with the radiant section of exhaust gases passes, the convection section that is provided with exhaust gases passes, the flue gas condenser that is provided with exhaust gases passes and chimney; Radiant section one end links to each other with combustion system, it is characterized in that, said radiant section, convection section, flue gas condenser and chimney connect to form the exhaust gases passes of perforation successively; Be provided with the radiant section tube bank of ring-type in the said radiant section exhaust gases passes; Be provided with the convection section tube bank in the convection section exhaust gases passes; The condenser bundles of dress condensate liquid cooled flue gas in being provided with in the condenser exhaust gases passes; And in condenser, being provided with the condenser tank, circulation has water in said radiant section tube bank, convection section tube bank and the condenser tank, and condenser tank, convection section tube bank and radiant section tube bank series connection successively.
Below the utility model is further described.
Further, said radiant section is horizontal, and exhanst gas outlet and gas approach place radiant section main body right ends respectively.
Further, said convection section is horizontal, and exhanst gas outlet and gas approach place convection section main body right ends respectively.
Further, said radiant section tube bank is in series by light pipe.
Further, said light pipe diameter is 70mm-127mm.
Further, be provided with at least 5 row's convection section tube banks in the said convection section, and be in series for light pipe near 3 rows or 4 row's convection section tube banks of radiant section, all the other convection section tube banks are in series for finned tube.
Further, the diameter of said light pipe is 60mm-127mm.
Further, the diameter of said finned tube is 60mm-127mm.
The course of work and the principle of condensed type combustion gas uphole steam generator are; 20 ℃ of left and right sides low pressure demineralized waters get into the condenser water inlet pipe; The organ pipe bundle that is condensed is delivered to oxygen-eliminating device by the condenser outlet pipe after being heated to about 65 ℃; Deaerated water is added by plunger displacement pump and is pressed into water under high pressure and gets into the convection section water inlet pipe after the deoxygenation; By the water inlet pipe of convection section outlet pipe entering radiant section, exported by the radiant section steam (vapor) outlet through the qualified steam that the radiant section tube bank is heated under required pressure (high pressure, super-pressure or subcritical pressure boiler) and the mass dryness fraction by current after the convection section tube bank is heated to about 280 ℃ for current.High-temperature flue gas after natural gas burns through combustion system is mainly with the working medium heat exchange of radiation heat transfer mode in the radiant section tube bank; Flue gas is reduced to about 950 ℃ and is got into convection section; Flue gas is mainly with the working medium heat exchange in the convection section tube bank of heat convection mode; Flue gas is reduced to about 160 ℃ and is got into flue gas condenser, and flue gas is the heat convection working medium heat exchange in condenser bundles so that phase transformation to be arranged mainly, and flue-gas temperature is reduced to about 50 ℃ and to be got into chimney and enter atmosphere.
Known that by above the utility model is the condensed type combustion gas uphole steam generator, the beneficial effect that it is compared with prior art had is:
1, cancelled the changeover portion that traditional uphole steam generator is not arranged heating surface, radiation loss is reduced, improved the injection boiler thermal efficiency and reduced the manufactured materials consumption;
2, cancelled the water-water heat exchanger of traditional uphole steam generator, water resistance is reduced, the plunger displacement pump power consumption is reduced;
3, flue gas condenser rationally reclaims sensible heat and the latent heat in the flue gas, reduces heat loss due to exhaust gas, improves the thermal efficiency of boiler, and the injection boiler thermal efficiency is reached more than 100%, and energy-saving effect is remarkable, and has reduced the pollution to environment;
4, radiant section and convection section are the high pressure boiler circuit, and flue gas condenser is a low pressure water system, and the manufacturing cost of flue gas condenser is reduced.
