Abstract
The utility model discloses pulverized coal furnace arched door type heat-transfer surface, the pulverized coal furnace arched door type heat-transfer surface is door-sheet, and inside is equipped with several heat exchanger tubes, the arrangement of heat exchanger tube ecto-entad, and it is accurate to arrange between lax, internal heat exchanger tube of arranging between external heat exchanger tube；Concentrate connection upper header and lower collecting box in the both ends of the heat exchanger tube；The pulverized coal furnace arched door type heat-transfer surface is arranged at the top of chimney arch for door-sheet and side.On the one hand the utility model pulverized coal furnace arched door type heat-transfer surface plays the role of supporting chimney arch, the heat exchanger tube in one side pulverized coal furnace arched door type heat-transfer surface can avoid the excessively high danger for causing to melt collapsing of chimney arch temperature to cooling down in furnace.
Description
Technical field
The utility model relates to pulverized coal furnace arched door type heat-transfer surfaces.
Background technique
Coal-powder boiler chimney arch is the extension space of entire lower furnace portion at present, is mainly used for laying burner, it is empty to provide burning
Between, it is contemplated that burner is that Pulverized Coal is spurted into burner hearth, can't burn at chimney arch, therefore the entire space of chimney arch
Often it is that castable is built, heat-transfer surface can't be laid, and in actual moving process, the material spray distance of burner is due to furnace
The influence of thorax interior flow field and dust, material spray distance shorten dramatically, the Forward of flame combustion center, even up at chimney arch, due to
There is no heating surface arrangement at chimney arch, so that chimney arch temperature is excessively high or even melts collapsing, faces blowing out risk.
Utility model content
The purpose of this utility model is to provide pulverized coal furnace arched door type heat-transfer surfaces, it is intended to solve the above problems.
To achieve the goals above, the technical solution of the utility model is design pulverized coal furnace arched door type heat-transfer surface, described
Pulverized coal furnace arched door type heat-transfer surface is door-sheet, and inside is equipped with changing for several heat exchanger tubes, the arrangement of heat exchanger tube ecto-entad, and outside
It arranges lax, arranges between internal heat exchanger tube accurate between heat pipe；Concentrate connection upper header under in the both ends of the heat exchanger tube
Header；The pulverized coal furnace arched door type heat-transfer surface is arranged at the top of chimney arch for door-sheet and side.
Further, the pulverized coal furnace arched door type heat-transfer surface is membrane wall heat-transfer surface.
Advantages and beneficial effects of the utility model lie in that on the one hand the utility model pulverized coal furnace arched door type heat-transfer surface rises
To the effect of support chimney arch, the heat exchanger tube in one side pulverized coal furnace arched door type heat-transfer surface can be avoided to cooling down in furnace
Chimney arch temperature is excessively high to be caused to melt the danger collapsed.
Detailed description of the invention
Fig. 1 is the utility model main view.
Fig. 2 is the utility model side view.
Fig. 3 is main view partial enlarged view.
Fig. 4 is side view partial enlarged view.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and cannot be used as a limitation the protection model of limitation the utility model
It encloses.
Embodiment:
Pulverized coal furnace arched door type heat-transfer surface, the pulverized coal furnace arched door type heat-transfer surface 1 are door-sheet, and inside is equipped with several change
Heat pipe 2, the arrangement of 2 ecto-entad of heat exchanger tube, and essence of arranging between the heat exchanger tube 2 for arranging lax, internal between external heat exchanger tube 2
It is close；Concentrate connection upper header 4 and lower collecting box 3 in the both ends of the heat exchanger tube 2；The pulverized coal furnace arched door type heat-transfer surface 1 is door-plate
Shape setting is in 5 top of chimney arch and side.The region of upper header 4 and the disengaging of 3 formula coolant liquid (gas) of lower collecting box.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
