Abstract
The utility model provides a boiler structure with a boiler barrel and headers. By the boiler structure, normal heat transfer of a boiler can be guaranteed, and manufacturing of the boiler is little in steel consumed and low in cost. The boiler structure comprises the upper boiler barrel and convection pipes with upper ends connected with the upper boiler barrel respectively. The boiler structure with the boiler barrel and the headers is characterized in that at least two headers are arranged below the convection pipes, each header is correspondingly communicated with the convection pipe at corresponding position on an upper portion, not all positions of the headers are on a horizontal plane, positions of the convection pipes are arranged according to a curve of an boiler arch, lower ends of the convection pipes are respectively communicated with the headers right below.
Description
Technical field
The utility model relates to the technical field of structures of boiler, is specially a kind of boiler structure with drum and header.
Background technology
Existing double-drum boiler, see Fig. 1, it comprise upper drum 1 ', lower drum 2 ', every convection tube 3 ' be communicated with respectively upper drum 1 ', lower drum 2 ', because lower drum 2 ' the position fix, lower drum 2 ' need size enough could connect respectively greatly every convection tube 3 ', the extra length of convection tube 3 ' also need go to connect lower drum 2 ', so that the spent steel material of whole boiler is large, manufacturing cost is high.
Summary of the invention
For the problems referred to above, the utility model provides a kind of boiler structure with drum and header, and it is when guaranteeing the normal conveying of boiler heat, so that boiler is made spent little, the low cost of manufacture of steel material.
A kind of boiler structure with drum and header, its technical scheme is such: it comprises upper drum, convection tube, the upper end of described convection tube connects respectively described upper drum, it is characterized in that: the arranged beneath of described convection tube has header, described header has two at least, the corresponding described convection tube that is communicated with its corresponding position, top of each described header, the position of described header is not entirely on the same level face, the position of described convection tube is according to the arrangement of curves of chimney arch, and the lower end of described convection tube is communicated with respectively the described header that is positioned under it.
After adopting said structure of the present utility model, because header has two at least, the corresponding described convection tube that is communicated with its corresponding position, top of each header, the position of header is not entirely on the same level face, and the position of convection tube is according to the arrangement of curves of chimney arch, the lower end of convection tube is communicated with respectively the header that is positioned under it, itself so that according to the convection tube of the arrangement of curves of chimney arch can directly connect its lower end under header, guarantee to improve to greatest extent heating surface area, in addition, header also need not to accomplish large scale to adapt to the convection tube of side, and convection tube also need not extra length and goes to connect header; To sum up, it is when guaranteeing the normal conveying of boiler heat, so that boiler is made spent little, the low cost of manufacture of steel material.
Description of drawings
Fig. 1 is the structural representation of existing double-drum boiler;
Fig. 2 is front view structural representation of the present utility model;
Fig. 3 is left view structural representation of the present utility model.
The specific embodiment
See Fig. 2, Fig. 3, it comprises upper drum 1, convection tube 2, the upper end of convection tube 2 connects respectively upper drum 1, the arranged beneath of convection tube 2 has header 3, and header 3 has two at least, each header 3 corresponding convection tube 2 that are communicated with its corresponding position, top, the position of header 3 is not entirely on the same level face, the position of convection tube 2 is according to the chimney arch arrangement of curves of (belonging to existing mature structure, not shown in FIG.), and the lower end of convection tube 2 is communicated with respectively the header 3 that is positioned under it.
