Referring to fig. 1 to 3, the present disclosure provides a combustion furnace including a housing 1, a combustion chamber 2, and a heat collecting cylinder 3.

The top of the housing 1 is provided with a heat supply port 11, and the housing 1 is provided with an air vent 12 for supplying oxygen for combustion in the combustion chamber 2.

A combustion chamber 2 is provided in the housing 1, mainly for supplying heat or flame.

The heat collecting cylinder 3 is a cylindrical structure with two open ends and is positioned above the combustion chamber 2, one end of the heat collecting cylinder 3 is communicated with the heat supply port 11, and the other end of the heat collecting cylinder 3 is communicated with the combustion chamber 2.

With the combustion furnace provided by the embodiment of the present disclosure, heat or flame generated in the combustion chamber 2 can be conducted to the vent 12 by providing the heat collecting cylinder 3, and a user can cook food or boil water through the vent. In addition, the user can directly put the ignition material from the high position of the combustion furnace through the vent hole, thereby being convenient for the user to operate.

Optionally, the burner further comprises: the heat collecting cylinder 3 is provided with the first ventilation hole group 31 for providing oxygen for the heat collecting cylinder 3, so that the non-burnt flue gas and fine particles can be more fully combusted, and the emission of the flue gas is greatly reduced.

Optionally, the burner further comprises: the heat collecting cylinder 3 is spirally provided with the second vent hole group 32 from bottom to top along the cylinder wall, so that oxygen can be continuously provided for the heat collecting cylinder 3, and the unburned flue gas in the flame can be helped to be combusted.

Optionally, the burner further comprises: and an oxygen supply pipe 4 having one end communicating with the first vent hole group 31 and the other end communicating with the vent hole 12, the first vent hole group 31 being located at an upper portion of the heat collecting cylinder 3 for supplying oxygen to the upper portion of the heat collecting cylinder 3.

Optionally, the burner further comprises: the storage bin 5 is arranged in the shell 1, and the storage bin 5 is positioned above the combustion chamber 2; one end of the material conveying pipe 51 is communicated with the storage bin 5, and the other end is communicated with the combustion chamber 2. The storage bin 5 is arranged above the fuel chamber, so that fuel can be conveniently conveyed and stored.

Alternatively, the storage bin 5 is located obliquely above the combustion chamber 2, and the feed conveyor pipe 51 is arranged obliquely.

Optionally, a bin cover 52 is disposed on the feeding port of the storage bin 5, and the bin cover 52 is hinged to the feeding port, so that a user can input fuel conveniently.

Optionally, the burner further comprises: the combustion chamber 2 is provided with a grid 6, and the grid 6 is used for carrying fuel. The aperture of the grid 6 is smaller than the diameter size of the biomass particle fuel.

Optionally, the burner further comprises: and the ash collecting box 7 is positioned below the grating 6 and is used for collecting plant ash after the biomass fuel is combusted.

Optionally, the burner further comprises: cooking means for being placed above the heat supply port 11.

When the combustion furnace is used, when biomass pellet fuel is thrown into the storage bin 5, the biomass pellet fuel slides down the inclined delivery pipe 51 to the grid 6 at the bottom of the combustion chamber 2 under the action of gravity, the size of the aperture/gap of the hole in the grid 6 is smaller than the diameter of the biomass pellet fuel, and thus the biomass pellet fuel which is not combusted falls on the grid 6 but cannot fall down. The grate 6 is surrounded by the side walls of the combustion chamber 2 to form a closed space, so that the biomass particles are collected to fall into the closed space of the combustion chamber 2 to form a small heap.

When the biomass particle fuel on the grid 6 is ignited, oxygen in the combustion chamber 2 is consumed, so that the pressure of the air in the combustion chamber 2 is reduced and a pressure difference is formed between the air in the external space. External air flows into the combustion chamber 2 through the air ports 12 of the housing 1 to assist in the combustion of the fuel.

A cylindrical heat collecting cylinder 3 is fixed at the upper part of the combustion chamber 2, a second ventilation hole group 32 is distributed on the surface of the heat collecting cylinder 3 along a spiral line from bottom to top, and a circle of first ventilation hole group 31 is arranged on the surface part of the upper edge of the heat collecting cylinder 3. The heat collecting cylinder 3 is fixed with the combustion chamber 2 by a bracket. Four oxygen supply pipes 4 are distributed at four corners of the bracket, the upper ends of the oxygen supply pipes 4 are fixed on the bracket and communicated with the first vent hole group 31, and the lower ends are connected to the lower part of the combustion chamber 2 and communicated with the outside through the vent holes 12.

The shell 1 is arranged outside the combustion chamber 2, and the combustion chamber 2, the storage bin 5, the conveying pipeline 51 and the like are integrally wrapped in the shell 1. The bottom of the housing 1 is provided with a plurality of air ports 12, and the combustion chamber 2 is communicated with the outside through the air ports 12 to provide oxygen for combustion. Be provided with album ash box 7 below combustion chamber 2 bottom, grid 6, after the burning of the living beings pellet fuel on grid 6, the volume dwindles, becomes ashes, and these ashes just fall into album ash box 7 the inside through the hole on grid 6, are convenient for collect ashes like this, and the plant ash after the burning of living beings pellet fuel is fine fertilizer moreover. The inlet of the storage bin 5 is provided with a bin cover 52, and the bin cover 52 is fixed at the bin inlet through a rotating shaft and is opened and closed around the rotating shaft.

A circular hole is reserved on the shell 1 of the combustion furnace, and a small length of the heat collecting cylinder 3 extends out of the circular hole; is closed at the bottom of the combustion furnace.

When biomass pellet fuel is combusted in the combustion chamber 2, oxygen in the combustion chamber 2 is consumed, and outside air flows into the combustion chamber 2 through the ventilation opening to assist combustion. The flame and part of the smoke which is not burnt out rise along the heat collecting cylinder 3 from the combustion chamber 2, and in the rising process, the second ventilation hole group 32 which is distributed along the spiral line on the surface of the heat collecting cylinder 3 continuously provides oxygen to help the burning of the smoke which is not burnt out in the flame; the oxygen supply pipe 4 also supplies more oxygen from the outside to the upper part of the heat collecting cylinder 3 through the vent 12 to form secondary oxygen supply; when the unburned flue gas and fine particles reach the top of the heat collecting cylinder 3, the first ventilation hole group 31 arranged at the top provides oxygen again, so that the unburned flue gas and fine particles can be combusted secondarily more fully, and the emission of the flue gas is reduced to the maximum extent.

This application can conduct the heat or the flame that produce in the combustion chamber 2 to blow vent 12 through setting up heat collection tube 3, and the user can carry out the culinary art of food or use the kettle to boil water through the heat or the flame of heat supply mouth 11. In addition, the user can directly put the ignition material from the high position of the combustion furnace through the heat supply port 11, thereby being convenient for the user to operate.
