The invention discloses a fuel stove which comprises a fire adjusting system, an ignition combustion system, a scale removing system and an alcohol-based fuel gasification system. The scale removing system comprises a cleaning ring. The cleaning ring is provided with a driving mechanism used for driving the cleaning ring to move back and forth. The driving mechanism comprises an elastic telescopic pipe. A plurality of pressure relief holes are formed in the elastic telescopic pipe. The elastic telescopic pipe communicates with an air inlet pipe. The air inlet pipe is provided with a draft fan, and a block piece used for controlling the communication state of the air inlet pipe is slidably arranged on the air inlet pipe. The block piece and the cleaning ring adjust the communication state of the air inlet pipe through an adjusting mechanism composed of a gear and a rack, wherein the gear is matched with the rack. The alcohol-based fuel gasification system comprises a gasification mechanism and a feeding and filtering mechanism adjustable in power. Compared with the prior art, according to the fuel stove, alcohol-based fuel is sufficiently gasified, heat in the ignition and combustion system is reasonably utilized, the utilization rate of the heat is increased, resource waste is reduced, and scale in jet nozzles can be removed conveniently.
