Overwater flowing fire simulation device

The invention discloses an overwater flowing fire simulation device, which comprises: a combustion tank module, wherein the combustion tank module comprises an oil tray, the oil tray is provided with a combustion cavity, and liquid-state water is injected into the combustion cavity; an oil supply module, wherein the oil supply barrel of the oil supply module is used for supplying oil into the combustion cavity through an oil supply pipeline; a dyeing module arranged between the oil supply module and the combustion tank module and used for dyeing the oil supplied into the combustion cavity; and a collecting module used for collecting the combustion state in the combustion cavity, wherein the collecting module comprises a thermocouple, a heat flow meter and shooting equipment used for shooting the dyed oil product and the combustion spreading process of the oil product. According to the overwater flowing fire simulation device, the oil product is dyed before flowing into the combustion cavity, so that the diffu
