Description

High-low temperature controllable kang-through chimney heating stove

Technical Field

The utility model relates to a heating device, in particular to a high-low temperature controllable kang-passing chimney heating stove.

Background

The back-burning type heating stove can control the burning speed by controlling the air distribution during back burning, so the fuel burning is not intense during back burning, and the back-burning type heating stove is suitable for slowly heating water in the water jacket and keeping the stove temperature. The flame does not go upwards during back burning, so the device is not suitable for cooking and heating cookers. For cooking, the boiler needs to be positively burned, and the flame is upwards moved to heat the cooker. The fuel burns more intensely during normal burning, and the temperature of the formed flame and smoke dust is higher. The smoke dust generated by the normal combustion of the normal forward-reverse combustion conversion heating furnace is the same as the reverse combustion, enters the rear combustion chamber after exiting from the front combustion chamber and is discharged outside the furnace body, the temperature of the discharged smoke dust is higher than that of the reverse combustion, and the discharged smoke dust is discharged outside the furnace body without being fully absorbed by the furnace body, so that energy is wasted relatively. If the flue gas outlet of the heating furnace is connected with the kang, heat can be absorbed and utilized by the kang, and lost heat can be reduced, so that the energy conservation and environmental protection are facilitated. The common heating stove with the conversion between the forward and the reverse combustion is only provided with a smoke outlet, and is connected with a kang or a stove barrel without a choice, so that the stove is inconvenient to use.
