A heating device comprising a heating piece, a fixing seat and a heater, the heating piece having an active surface and a heating surface opposite to the working surface； the fixing seat is connected behind the heating surface by two brackets, The utility model has an opening, a neck is formed around the opening, and a screw hole is arranged on the neck. The screw hole is screwed with a screw through which the screw can be screwed into the opening； the heater has a fire-breathing a tube, the flame tube is sleeved into the opening, and is fixed to the opening via a screw above the neck. When the heater is activated, a flame generated at the end of the tube can heat the heating surface to warm the heating sheet. And the active surface can conduct thermal energy to the surface of the food to be heated.一種加熱裝置，包含一加熱片、一固定座及一加熱器，該加熱片具有一作用面及相對該作用面另面之受熱面；該固定座藉由兩支架連設於受熱面之後方，具有一開口，該開口周圍形成一頸部，該頸部上設有一螺孔，該螺孔上螺設有一螺固件，該螺固件係可通過該螺孔旋入該開口；該加熱器具有一噴火管，該噴火管係套設入該開口，並經由頸部上方之螺固件固定於該開口，當加熱器啟動時，該噴火管末端產生之火焰可加熱該受熱面，使該加熱片增溫，而該作用面則可傳導熱能至欲加熱之食物表面。
