The utility model discloses a combined stove frame with a movable energy gathering ring. The combined stove frame is characterized by being composed of a stove frame body and the energy gathering ring detachably installed on the stove frame body. Due to the fact that the structure that the energy gathering ring is movably or detachably arranged on the stove frame body is adopted, when the combined stove frame is used, the energy gathering ring is arranged, a large amount of heat irradiating outward through flames can be reflected to a pot bottom to carry out heating, the loss of the heat generated after fuel combustion is effectively reduced, the thermal effect utilization rate is increased, meanwhile, the heat irradiating outwards is effectively isolated from heating a switching piece, and the switching piece is convenient to use. The energy gathering ring can be moved away or taken out from the stove frame body under the situation that the energy gathering ring is not needed.
