Description

Detailed Description of the Invention The present invention provides a hot-air heater that burns rice husks as the main fuel, in which the exhaust pipe of a cyclone for charging rice husks installed inside the machine is communicated with the chimney, and the exhaust gas discharged from the cyclone is connected to the chimney. It is characterized by the fact that the combustion gas in the chimney is forcibly discharged by atmospheric pressure to achieve efficient combustion.

Hereinafter, the present invention will be explained in detail with reference to embodiment figures.

A heat exchanger 3 having a combustion chamber 2 at the lower end is installed in a closed casing 1, a chain loss stall 4 is provided in the combustion chamber 2, and a rice husk storage cylinder 5 is fixed to the front part of the casing 1. The lower end opening is brought close to the chain roost 4, and the injection cylinder 6 is communicated with the upper part of the chen ro stol 4 by penetrating the housing cylinder 5 from the central position of the front lower part of the casing 1, and communicates with the injection cylindrical 6, and the injection flame of the tahana 7 is used to spray the chen ro stol. 4. The rice husks supplied to the upper surface are combusted, the combustion gas heats the heating ventilation tube in the heat exchanger 3, and the outside air blown by the blower 8 is made to flow through the heating ventilation tube in the heat exchanger 3. Warm air is exhausted from an exhaust duct 9, and a flue 10 connected to the upper surface of the heat exchanger 3 is connected to a chimney 11 provided above the housing cylinder 5 to exhaust combustion gas. In the rice hull heater 12, a cyclone 13 connected to a blower for pressure feeding rice hulls is installed in the upper part of the rice hull storage cylinder 5, and an exhaust pipe 14 protruding from the upper surface of the cyclone 13 is communicated with the chimney 11. It consists of

Next, the effects of the present invention will be explained with reference to embodiment figures.

The rice husks in the rice husk storage cylinder 5 are transferred to the chain rostol 4 from the lower end opening, and are transferred to the back side together with the chain rostol 4 while being combusted by the injection flame of the burner 7, and the combustion gas rises inside the heat exchanger 3. At the same time, the internal heating ventilation pipe is heated, and the rice husks are discharged from the flue 10 to the chimney 11.The rice husks are forced into the rice husks storage pipe 5 by a blower and are separated from high-pressure air in the cyclone 13. The rice husks fall from the lower end and the high pressure air passes through the exhaust pipe 14 and reaches the chimney 11.
An upward ventilation force is applied to the chimney 11 while being released into the chimney 11 , and the combustion gas that has risen inside the heat exchanger 3 and has flowed into the flue 10 is forced to flow into the chimney 11 . This provides the remarkable effects described above, such as promoting efficient combustion of rice husks within the combustion chamber 2 without causing gas to stagnate within the combustion chamber 2.

Claims (1)

[Claims] 1 A chain roaster 4 is provided at the bottom of the sealed casing 1, and the rice husks are released from the lower end of the rice husk storage cylinder 5 provided at the front position of the casing 1 into the rotating chainroostor 4 to be combusted, and the combustion gas is heated. In the rice husk heater 12, the rice husk is stored in a rice husk heater 12 which is configured to exchange heat in the exchanger 3 and then discharge the rice husk from a flue 10 placed on the ceiling inside the casing 1 to a chimney 11 installed on the upper surface of the storage tube 5. A rice husk heater characterized in that a cyclone 13 connected to a blower for pressure feeding rice husks is installed at an upper position in a cylinder 5, and an exhaust pipe 14 protruding from the upper surface of the cyclone 13 is connected to a chimney 11. A forced smoke evacuation device using a cyclone for charging rice husks.
