The invention discloses a fire tube type heating device applied to a flue-cured tobacco three-dimensional seedling raising greenhouse. The fire tube type heating device is characterized by comprising a stove (1), a radiator and a flow guide draught fan (4), wherein the radiator is arranged at the bottom of a tobacco seedling raising tray bracket (3) inside the greenhouse, and a hot air inlet of the radiator is communicated with a smoke outlet (11) of the stove through a pipeline; a hot air outlet is connected to the flow guide draught fan (4); the radiator comprises multiple radiating tubes (21) and multiple fire boxes (22); the fire boxes (22) are hollow cavities with pipeline connecting ports at two ends; and the fire boxes are connected end to end through the radiating tubes. The fire tube type heating device applied to the flue-cured tobacco three-dimensional seedling raising greenhouse has a simple structure, convenience in use, high heat efficiency of the device, a fast heating speed and low use cost. The heating device adopts the fire tubes to heat directly in the greenhouse, so that the heat efficiency can be up to 85%, and 5 DEG C can be increased per each hour for a greenhouse of 240 cubic meters.
