Description

Technical Field

[0001] The utility model relates to the technical field of marine boilers, and more specifically, to a boiler heated by marine fuel oil. Background Art

[0002] Ships as means of transportation have different technical performances, equipment and structural types according to different usage requirements. Among them, seafaring ships are widely used. Ships are composed of a variety of structures, among which oil-fired boilers are one of their components. As steam-powered machinery that propels ships, and boilers that supply steam, ships need to use oil-fired boilers.

[0003] The operation of the oil-fired boiler provides power for the ship's operation, but there are various types of oil-fired boilers in the prior art. For example, the utility model patent CN215001532U discloses a vertical steam boiler for ships. The utility model is provided with a shock-absorbing base, a boiler fixing frame and a plurality of shock absorbers. The plurality of shock absorbers arranged in a four-corner truss type can synchronously dampen the boiler in multiple directions. Although the boiler has a shock-absorbing and buffering effect, it solves the problem of unstable boiler placement.

[0004] However, when a fuel oil boiler is working, combustion will produce flue gas containing a lot of heat, and sometimes there will be excess steam. The excess steam with a lot of heat will be directly discharged. Both situations will cause a waste of heat resources and low utilization rate. In order to avoid this phenomenon, it is very necessary to design a boiler that recovers the remaining heat resources. Utility Model Content

The interior of the vertical boiler 1 is connected with the chimney 2, and the chimney 2 is connected with the interior of the vertical boiler 1. When the vertical boiler 1 is working, a large amount of smoke will be generated and discharged from the chimney 2.

A recovery box 4 is installed on one side of the vertical boiler 1, and the excess exhaust pipe 3 runs through the recovery box 4. An exhaust pump 5 is installed on the top of the recovery box 4. The input end of the exhaust pump 5 is connected with a smoke outlet pipe 6, and the output end of the smoke outlet pipe 6 is fixedly connected to the top of the chimney 2. The exhaust pump 5 is started and its input end is used to exhaust the excess exhaust gas. The smoke derived from the smoke outlet pipe 6 is sucked, and the output end of the air pump 5 is connected to the guide pipe 7, and the guide pipe 7 runs through the recovery box 4, and the smoke enters the guide pipe 7 from the output end of the air pump 5. The guide pipe 7 can transport the exhausted smoke and send the smoke into the interior of the recovery box 4.
