なくなる。 The structure of this embodiment is as described above. Therefore, in the main combustor, only gas is sent from the main nozzle 3 to the burner 1 without any air mixing.
Therefore, for gas combustion, heat shield air inlet holes 14 and 14' at the lower part of the inner flame cylinder 5 and the side surface of the heat shield cylinder 8 are required.
More secondary air enters and the small hole of the outer cylinder 7, the red-hot cylinder 6
For example, through the small holes of the inner flame cylinder 5, the gas ejected from the burner flame hole 4 mixes with the gas, and initially some of the gas is pore-combusted in the lower part of the inner flame cylinder 5 and the small holes of the outer cylinder 7, and then It mainly burns between the inner flame cylinder 5 and the red-hot cylinder 6, and the unburned part burns at the upper opening of the inner flame cylinder 5 and the red-hot cylinder 6.
Combustion also occurs in the upper holes 29 and 30 of the inner flame cylinder 5, and the combustion in the lower pores almost disappears as the red-hot cylinder 5 becomes red hot.

その働きをするのが燃焼安全装置１６である。 Now, when the combustor is continuously burned and the oxygen in the air in the room becomes insufficient due to insufficient ventilation in the room, the combustor of the present invention will be red hot at around 830 degrees Celsius, but the oxygen
Even at around 16%, hydrogen-based gas (city gas) continues to glow red, and the amount of carbon monoxide generated does not differ much from the normal value, satisfying the JIS standards for a combustor. This is because the nearby air and unburned gas mix well in the upper part and the upper hole 2 of the inner flame tube 5.
This is because the area around 9.30 is red hot and good combustion occurs even there. However, although the amount of carbon monoxide produced is low, 16% oxygen is not sanitary, so it is necessary to stop burning the appliances before that happens.
The combustion safety device 16 performs this function.
燃焼安全装置１６の働きは次の如くである。 The operation of the combustion safety device 16 is as follows.

る。 In general, the lifting and extinguishing phenomena of Bunsen burners occur when the oxygen concentration reaches approximately 13% or 11 to 12% in the case of hydrogen-based gases. However, as mentioned above, 16
It would be impossible to stop the gas before the oxygen concentration reached % with a normal Bunsen burner. Therefore, if the combustion is started in an atmosphere of 10-10% oxygen, and the above-mentioned lift and fire extinguishment occur when the oxygen in the room reaches 17% to 19.5%, the goal can be achieved. The auxiliary flame holes 22, 22' in the explanation of the structure serve to create an oxygen-deficient condition in the outer wall 25, and the air supplement to the primary flame A1 of the main flame hole 21 of the safety device main burner 23 is provided in the outer wall. However, due to the combustion in the auxiliary flame holes 22, 22', the air quickly becomes deficient in oxygen, and the external flame B 1 at the outer wall 25 changes from the primary flame A 1 →A 2 With this, the shape becomes B 1 →B 2 . The thermocouple 19, which had been heated by the primary flame A1 , changes its primary flame to A2 , and the electromotive force decreases as the heating temperature decreases, and the safety valve unit 18 operates to close the gas and release the secondary air. It can also stop the gas in the combustor body that was burning.

1. Auxiliary flame holes 22, 22', auxiliary air holes 26, 2
7. It is possible by selecting appropriate values for the size and proportion of the dimensions of the primary air hole 20, the distance between the upper end surface of the outer wall 25 and the upper end surface of the main flame hole 21, the position of the thermocouple 19, etc.

れるという効果が得られるのである。 As described above, the present invention provides a red-hot cylinder made of a wire mesh, a punched plate, a lath net, etc. on the outside of an inner flame cylinder having a plurality of small holes, and a heat-resistant, heat-transmitting material and a heat-shielding material on the outside. In a combustor equipped with a cylinder consisting of a cylinder, etc., a combustion safety device is installed in the inner flame cylinder, and this combustion safety device is equipped with a Bunsen burner with an auxiliary flame hole below the main flame hole, and this Bunsen burner. An outer wall that wraps the outer circumference higher than the main flame hole and lower than the auxiliary flame hole, an auxiliary air hole provided at the bottom of this outer wall, and a thermocouple installed above the main flame hole. Therefore, the flame in the main flame hole of the combustion safety device quickly becomes oxygen-deficient, and as a result, the gas can be stopped before it poses any danger to the human body, making it extremely safe. Since the combustion safety device is installed, firstly, indoor air is flowing into the inner flame cylinder, so oxygen deficiency conditions in the room can be detected quickly and appropriately, and secondly, the main flame hole of the combustion safety device can be detected quickly and appropriately. The flame is less likely to fluctuate due to outside wind, etc., and stable oxygen deficiency detection can be performed. Thirdly, since it is installed in an idle space within the inner flame cylinder, it can be made more compact.
