Embodiment Construction
[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0013] Such as figure 1 , figure 2 As shown in , the steam drum structure in the dry-back horizontal marine oil-fired boiler includes a steam drum shell 2 arranged on the top of the drum 1 and communicated with the drum 1 . The upper end of the steam drum shell 2 is provided with a steam-water separation chamber 3, the steam-water separation chamber 3 is formed by a top plate 31, a side plate 32 and a bottom plate 34, and the bottom of the top plate 31 in the steam-water separation chamber 3 is fixedly provided with a circle of baffles 4. The side plate 32 outside the area of the baffle plate 4 is provided with a number of side steam inlet holes 321 at intervals. In this embodiment, the side plate 32 is provided with upper and lower circles of side steam inlet holes 321. The steam holes 321 are evenly spaced along the circumfere...

The invention discloses a steam drum structure in a dry-back-horizontal-type marine oil-fired boiler. The steam drum structure comprises a steam drum shell arranged at the top of a boiler barrel and communicating with the boiler barrel, wherein a steam-water separation chamber is arranged on the upper end part in the steam drum shell, the steam-water separation chamber is formed by enclosing a topplate, side plates and a bottom plate, a circle of baffles are fixedly arranged at the bottom of the top plate in the steam-water separation chamber, a plurality of side steam inlet holes are formedat intervals in the side plates outside the baffles, and a steam outlet pipe is arranged in the steam-water separation chamber; and a steam inlet end opening of the steam outlet pipe extends into thecircle of baffles, a steam passing clearance is formed between the steam outlet pipe and the baffles, and a steam outlet end opening of the steam outlet pipe penetrates through the bottom plate and extends outwards from the inner part of the steam drum shell. The steam drum structure has the advantages that the steam space of the boiler barrel of the dry-back-horizontal-type oil-fired boiler can be reduced by about 70%, the diameter of the boiler barrel can be further reduced, and the mass of the dry-back-horizontal-type oil-fired boiler can be reduced by about 20%.
Description
technical field [0001] The invention relates to the field of marine boilers, in particular to a horizontal marine oil-fired boiler. Background technique [0002] Marine oil-fired boilers mainly use high-temperature flue gas generated by diesel combustion. Due to the limited space of ships, volume and height are always the primary technical problems to be solved for marine boilers. The height of the horizontal marine boiler is reduced, but the height of steam-water separation in the boiler is very limited. In order to increase the distance of steam-water separation, the current practice is usually to leave a sufficient height of steam space in the drum. Although this approach solves the problem of the height of the separation of steam and water, the volume of the drum cannot be reduced, or even increased. Contents of the invention [0003] The object of the present invention is to provide a steam drum structure in a dry-back horizontal marine oil-fired boiler, which has a...
