This utility model discloses a heating stove, belonging to the field of heating equipment, including a main combustion chamber and a secondary combustion chamber. A second air inlet structure is provided in the upper part of the main combustion chamber, which provides oxygen for the combustion of fuel within the main combustion chamber. A flue is provided between the main and secondary combustion chambers, and a third air inlet structure is provided at the flue, which provides oxygen for the flue gas produced by fuel combustion. The second air inlet structure of this utility model can provide oxygen for the combustion of fuel within the main combustion chamber, reducing the amount of flue gas produced in the main combustion chamber. The third air inlet structure also allows for more complete combustion of the flue gas, making full use of the flue gas produced in the main combustion chamber and further reducing emissions, enabling the heating stove to achieve smokeless heating.

The utility model relates to the technical field of heating furnaces, in particular to a combined tent heating furnace which comprises a heightening seat, a main frame is fixedly connected to the top of the heightening seat, an auxiliary frame is slidably connected to the interior of the main frame, a fixing sleeve is fixedly connected to the bottom end of the inner side of the main frame, and a lifting plate is slidably connected to the interior of the fixing sleeve. A through groove is formed in the inner side wall of the auxiliary frame, the size of the inner structure of the through groove is larger than that of the outer structure of the fixing sleeve, a straight groove is formed in the outer portion of the fixing sleeve, an inclined groove is formed in the straight groove, limiting grooves are formed in the two ends of the straight groove respectively, and bevel edges are arranged on one sides of the two limiting grooves. Compared with an existing combined type tent heating furnace, the combined type tent heating furnace has the advantages that due to the design of the limiting columns and the inclined grooves, multi-stage adjustment of the overall height can be rapidly completed, and the overall practicability is greatly improved.
