Vertical steam boiler experimental device suitable for offshore platform

The utility model relates to a vertical steam boiler experimental device suitable for an offshore platform. The vertical steam boiler experimental device comprises a steam boiler; the oil tank is connected with a liquid inlet of the steam boiler through an oil conveying pipeline; the air distributor is arranged in the steam boiler and used for feeding air conveyed by the air blower into the steam boiler at a preset angle; an air outlet of the air blower is connected with an air inlet of the air distributor through an air conveying pipeline. The optimal combustion parameters of crude oil can be obtained by adjusting the viscosity of the crude oil, the air inlet amount of the boiler, the air inlet angle and the like, and therefore the problem that the boiler is coked and scaled due to insufficient combustion of the crude oil is solved; in addition, the crude oil viscosity can be reduced through the heater, the crude oil viscosity can be improved through the cooler, and therefore the combustion conditions of cru
