The invention discloses a spray type alcohol gasifying device. The spray type alcohol gasifying device comprises a main body arranged in a closed manner; an atomizing nozzle is arranged in the main body, and is positioned at the upper part of the main body; a heating device is arranged in the main body, and is positioned below the atomizing nozzle; and a gas output mechanism is arranged on the main body. The spray type alcohol gasifying device has the following beneficial effects: the atomizing nozzle is arranged above the heating device, so that the gasifying speed of alcohol liquid can be accelerated, and gasified alcohol gas fuels can be continuously supplied to a combustor within shorter time; and meanwhile, the atomized alcohol liquid is heated to increase the heated area of liquid, so that the gasifying temperature can be quickly reached after contacting with a heat source, and the overall gasifying efficiency can be improved in continuous flowing of output gas.
