The invention relates to an intelligent gasification furnace and a control method thereof. The intelligent gasification furnace comprises a combustion net, a fuel pipe, an ignition air control and material control valve, a gasification chamber, an ignition sensor, a fuel pump, a fuel tank, another gasification chamber, a solenoid valve, an oil nozzle, an annular air injection port, a combustion port, a preheating chamber, a pulse igniter, an intelligent controller, a sensor and an air injection groove. The intelligent gasification furnace solves the problems that an existing intelligent gasification furnace valve is low in work efficiency, firepower is not stable, fuel cannot be combusted fully, gas escapes easily, and air content of mixed gas is non-uniform. According to the intelligent gasification furnace, oil is controlled automatically, the fuel is saved, the structure is simple, the firepower is stable and safe, the gasification speed is high, gas is mixed uniformly, and operation is convenient. The operation method is the same as that of an existing cooking range commonly used. The intelligent gasification furnace protects environment and is economical, and liquefied gas can be replaced.
