PROBLEM TO BE SOLVED: To eliminate some defects found in a heating stove with firewood as its fuel that it shows a poor combustion efficiency due to heat radiation from a wall surface enclosing a combustion chamber, produces soot or smoke and the like and at the same time a location that can be used as a heat source is limited to a place near the heating stove of a heater and further energy that can be utilized as a heating operation or heat source is limited to heat radiation from the combustion chamber and a vertical flue, i.e. radiation heat, convective heat.SOLUTION: A rocket stove is constituted such that there are provided a plurality of air chambers defined in a height direction along an outer wall of an outer vertical flue, each of the air chambers is communicated to each other through fine holes, a lower air chamber is formed with an air flowing-in port and an upper air chamber is formed with an air discharging port. In addition, a water pipe is wound around an inner wall of the outer vertical flue in a coil-like manner and at the same time a water supplying port is arranged below it and a hot water discharging port is arranged above it. Further, a horizontal flue is extended into a greenhouse and connected to a vertical flue outside the greenhouse. |
