The invention discloses a dry-back-horizontal-type marine oil-fired boiler with small occupied space and good steam-water separation effect. The dry-back-horizontal-type marine oil-fired boiler comprises a boiler barrel, wherein a second smoke chamber is arranged at one end of the boiler barrel, and a first smoke chamber and a third smoke chamber are arranged at the other end of the boiler barrel;a boiler furnace, first heat exchange pipes and second heat exchange pipes are arranged in the boiler barrel, a smoke inlet in the side wall of the second smoke chamber communicates with one smoke inlet end of the boiler furnace, and the first smoke chamber communicates with one smoke discharging end of the boiler furnace; the first smoke chamber and the second smoke chamber communicate with thetwo ends of the first heat exchange pipes, the second smoke chamber and the third smoke chamber communicate with the two ends of the second heat exchange pipes correspondingly, and a smoke dischargingpipe is arranged at the top of the third smoke chamber; and a steam drum with a steam-water separation chamber is arranged at the top of the boiler barrel, a baffle is fixed to the bottom of a top plate in the steam-water separation chamber, a side steam inlet hole is formed in a side plate outside the baffle, the steam separation chamber is internally provided with a steam outlet pipe, a steam inlet end opening of the steam outlet pipe extends into a circle of the baffle, and an outlet end opening of the steam outlet pipe extends out through a bottom plate.
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 purpose of the present invention is to provide a dry-back horizontal marine oil-fired boiler with good steam-water separation effe...
