The invention relates to the technical field of tobacco curing equipment, in particular to a hot-gas fin tobacco curing barn making use of alcohol-base fuel, wherein the hot-gas fin tobacco curing barn making use of alcohol-base fuel comprises a tobacco curing barn which is provided with a tobacco hanging rack, and further comprises a hot-gas fin device which is arranged on a wall; the tobacco hanging rack comprises vertical rods which are vertically arranged, and transverse rods which are transversely arranged; supporting legs are arranged on the lower parts of the vertical rods; tobacco clips are arranged on the transverse rods; the hot-gas fin device is connected to a heating device; and the heating device is an alcohol-base fuel heating device. The tobacco curing barn is used for curing tobacco leaves by virtue of hot gas radiated from the hot-gas fin device, and the hot-gas fin device is relatively small in volume and is space-saving, so that the tobacco leaves are effectively roasted. Moreover, the alcohol-based fuel heating device, which uses alcohol base as fuel, is environment-friendly and is clean; and the alcohol-based fuel, which has the characteristics of being clean and sanitary, safe, cheap, easy to purchase raw materials, convenient to use and the like, is a biomass clean energy which is encouraged by the state to develop.
