Abstract
The invention provides an arrangement structure of a subcritical circulating fluidized bed boiler. A steam pocket is arranged between a hearth and a cyclone separator in stead of boiler front arrangement, and a steam pocket down-comer is downwards arranged along the rear wall of the hearth; therefore, the problems of difficult coal supply of the subcritical circulating fluidized bed boiler and difficult arrangement of the down-comer are solved, and meanwhile, the boiler increases large boiler front space on arrangement and is convenient for operation, maintenance and overhauling.
Description
Technical field
The present invention relates to a kind of arrangement of subcritical cycle fluidized-bed combustion boiler.
Background technology
The subcritical cycle fluidized-bed combustion boiler finds broad application in China, and most subcritical cycle fluid bed boiler water-cooling system adopts the mode of Natural Circulation, boiler adopts drum boiler, according to common technology, in the boiler entire arrangement, as shown in Figure 1, be that drum 5 ' is arranged in the preceding space of burner hearth 1 ', arrange burner hearth 1 ', cyclone separator 2 ', material returning device 3 ' and afterbody convection pass 4 ' then successively.The conveying preparation of boiler combustion, induction system mostly are arranged in the front of boiler, adopt the mode of front-furnace feeding.The batcher 8 ' that frequent discovery stokehold is connected with as-fired fuel storehouse 7 ' in the layout of power plant and the phenomenon of boiler down-comer 6 ' collision, want exactissima diligentia in design process, simultaneously can find that also coal supply system and drum down-comer system all are arranged in the interval, stokehold, the space of operating maintenance is very little.
Summary of the invention
The arrangement of a kind of subcritical cycle fluidized-bed combustion boiler provided by the invention, drum arranged to change into by the stokehold be arranged between burner hearth and the cyclone separator, drum down-comer wall behind the burner hearth is arranged downwards, solved the problem of subcritical cycle fluidized-bed combustion boiler coal supply and down-comer difficult arrangement, boiler makes the space, stokehold big on arranging simultaneously, is convenient to operation maintenance and maintenance.
In order to achieve the above object, the invention provides a kind of arrangement of subcritical cycle fluidized-bed combustion boiler, this boiler comprises burner hearth, and be arranged on the burner hearth back space, the material return system, cyclone separator, the afterbody convection pass that connect burner hearth successively, also comprise and be arranged on the furnace front space, connect the batcher and the as-fired fuel storehouse of burner hearth successively.
Described boiler also comprises drum and the down-comer that is connected drum and burner hearth, and described drum and down-comer are arranged between burner hearth and the cyclone separator, and the drum down-comer is arranged downwards along the space between burner hearth and the cyclone separator, supplied water to burner hearth.
The present invention has the following advantages:
1, solves the space Layout Problem of boiler-steam dome down-comer and stokehold coal supply system, for the layout of recirculating fluidized bed stokehold feeder provides maintenance and space for maintenance.
2, drum is arranged in the space that makes full use of between burner hearth and the cyclone separator, has dwindled the floor space of boiler, saves the cost of boiler steel structure.
Description of drawings
Fig. 1 is the arrangement of subcritical cycle fluidized-bed combustion boiler in the background technology.
Fig. 2 is the arrangement of a kind of subcritical cycle fluidized-bed combustion boiler provided by the invention.
The specific embodiment
Followingly specify preferred embodiment of the present invention according to Fig. 2:
As shown in Figure 2, it is a kind of arrangement of subcritical cycle fluidized-bed combustion boiler, this boiler comprises burner hearth 1, and be arranged on the burner hearth back space, the material return system 3, cyclone separator 2, the afterbody convection pass 4 that connect burner hearth 1 successively, also comprise and be arranged on the furnace front space, connect the batcher 8 and the as-fired fuel storehouse 7 of burner hearth 1 successively.
Described boiler also comprises drum 5 and is connected the down-comer 6 of drum 5 with burner hearth 1, described drum 5 and down-comer 6 are arranged between burner hearth 1 and the cyclone separator 2, drum down-comer 6 is arranged downwards along the space between burner hearth 1 and the cyclone separator 2, is supplied water to burner hearth.
Although content of the present invention has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple modification of the present invention with to substitute all will be conspicuous.Therefore, protection scope of the present invention should be limited to the appended claims.
