Abstract
The utility model relates to a reinforcing device for a heating surface of a large circulating fluidized bed boiler. When the boiler is enlarged, parameters are improved, and evaporation capacity is increased, the increase of the evaporation heating surface of the boiler is not obvious, so that increasing more heating surfaces plays a key role in improving the evaporation capacity and controlling bed temperature of the large circulating fluidized bed boiler. The reinforcing device for the heating surface of the large circulating fluidized bed boiler comprises a tube panel (3) arranged in a hearth, wherein two ends of a heating surface (2) of the tube panel are respectively connected with a group of uniform flange reinforcing panels (4). The reinforcing device is used for reinforcing the heating surface in the circulating fluidized bed boiler.
Description
Technical field:
the utility model relates to a kind of field of boilers, is specifically related to a kind of stiffening device that is used for large circulating fluidized bed boiler stove internal heating surface.
Background technology:
in order to improve power plant efficiency, the parameter of boiler also improves thereupon for large circulating fluidized bed boiler.When boiler increased raising parameter increase evaporation capacity, the increase of boiler evaporating heating surface was not obvious, therefore increased more heating surface and can play key effect to improving evaporation capacity with the bed temperature of controlling large circulating fluidized bed boiler.
Since
large circulating fluidized bed boiler present domestic independent research, that have independent intellectual property right put into operation, heating surface difficult arrangement that in design process, occurs and the burner hearth central burner temperature that in actual motion, occurs were higher than design load.
Summary of the invention:
The purpose of
the utility model provides a kind of device that is used for large circulating fluidized bed boiler stove internal heating surface of indeformable in fluid bed boiler furnace, reinforced structure.
Above-mentioned purpose realizes through following technical scheme:
a kind of stiffening device that is used for large circulating fluidized bed boiler stove internal heating surface, its composition comprises: be installed in the tube panel in the burner hearth, it is characterized in that: the heating surface two ends of described tube panel connect one group of equal edge of a wing and strengthen screen; The described equal edge of a wing is strengthened screen and is membrane wall tube panel structure, and it is the membrane type pipe of one or two vertical boiler tube panel direction lateral arrangement that screen is strengthened on the described equal edge of a wing; Described membrane type pipe is that light pipe adds fin and is welded.
Beneficial effect:
Reinforced heating surface is arranged in
1. the utility model in burner hearth, prevent the heating surface temperature distortion, and can be a plurality of in the layout in a lateral direction of vertical boiler, has increased the area of burner hearth internal heating surface.
the utility model has been strengthened the intensity of tube panel, and has guaranteed that this operation is an overtemperature, indeformable not.
Description of drawings:
accompanying drawing 1 is the structural representation of this product.
accompanying drawing 2 is that this product is contained in the structural representation in the burner hearth.
accompanying drawing 3 is that water-cooled wall formula screen two ends connect the structural representation that screen is strengthened on an equal edge of a wing in the accompanying drawing 1.
The specific embodiment:
Embodiment 1:
are used for the stiffening device of large circulating fluidized bed boiler stove internal heating surface, and its composition comprises: be installed in the tube panel 3 in the burner hearth 1, heating surface 2 two ends of described tube panel connect one group of equal edge of a wing and strengthen screen 4.
Embodiment 2:
Embodiment 3:
water-cooled wall formula is shielded, all reinforcement screen in the edge of a wing is membrane wall tube panel structure, adds fin by light pipe to be welded, and the two ends of screen are connected with the mode of welding with import and export collection case respectively.
Reinforced heating surface is arranged in
in burner hearth, prevent the heating surface temperature distortion, and can be a plurality of in the layout in a lateral direction of vertical boiler.
