る。It is only a very small amount, and it gradually increases until it becomes a stone, not producing enough - as a heat source for the boiler, but eventually, as dry distillation progresses, the amount of gas generated gradually decreases, and there is a shortage of i calories as a heat source for the boiler. Eventually, combustion cannot be continued with the generated gas alone, the temperature of the combustion chamber decreases, and unburned gas accumulates in the equipment that follows the kiln.
There was a drawback that it could explode for some reason or be emitted as unburned black smoke.In addition, in the case of gaseous fuel, the mixture of air and tl in advance can be used in a combustion device such as a burner. However, there was a limit to the space available for a single burner, and in order to achieve large combustion and suction, it was necessary to arrange many burners in parallel and provide separate combustion chambers. The present invention aims at a combustion device and a gas safe combustion device which do not have the above-mentioned disadvantages. For ignition of gas combustion chamber? A raw gas inlet connected to a gas source is opened in a peripheral wall located perpendicular to the wall surface equipped with the burner, close to the wall surface where the burner opens, and a raw gas inlet connected to the gas source is opened in this peripheral wall. The air is carried to the blower, and a large number of air pipes equipped with valves that adjust the amount of air are opened in many rows, and furthermore, on the wall opposite to the wall where the front burner is installed, there is a pipe that connects to the heat exchanger. A gas combustion apparatus is provided with a photoelectric element for detecting light, and a device for controlling the ignition and extinguishing metal side of the burner in response to the amount of light received by the photoelectric element. The drawings showing examples will be explained in more detail: A gas combustion chamber 1 is surrounded by a fireproof insulating material such as firebrick or a water-cooled wall 2, and the outer wall is made of a metal casing 3.
An ignition burner 5 using oil or gas as fuel opens on one wall surface 4 of the combustion chamber, and the burner A fuel gas source, for example, an unburned gas introduction lower which is delayed to the dry distillation furnace (7) is provided in the vicinity of the wall surface where the burner 5 opens, and is opened in the peripheral wall surface 6 perpendicular to the wall surface 4 where the burner 5 opens.
A large number of air jet holes 8t in each row of multiple rows parallel to the wall and surface 4
Each of these is connected to a blower pipe 9 equipped with a flow rate control valve that passes through the peripheral wall 2, and the wall surface facing the wall surface 4 where the burner 5 opens is connected to a heat exchanger etc. from which the combustion high temperature gas is discharged. In response to the amount of light received by the photoelectric element 13 installed in the hole 12 through which the outlet port lO penetrates, the power source for the ignition valve 1''4 of the burner 5 and the oil solenoid valve 15 is activated. This is a gas combustion device equipped with a control value g (7#) that controls the energization to the burner operation panel 16 that operates the burner operation panel 16.

する極めて有効な発明である、When the changeover switch C081 is set to manual (indicated by the broken line), the burner can be used in the normal manner using the burner operation panel 16. Since the structure of this invention is as described above, combustion is started from the unburned gas introduction lower. The raw gas introduced into the chamber 1 is ignited by a burner before it is mixed with air, and then is ejected from an air jet hole 8 connected to a blow pipe 9 equipped with an air volume control valve (not shown). It burns when it comes into contact with the air
At this time, the air volume control valve installed on the blower pipe can be operated to blow air into the gas combustion chamber l according to the amount of gas introduced and the combustion state, so that the fuel gas can be effectively combusted. - 'If the gas introduced from the unburned gas introduction lower is gas generated in the dry distillation furnace, the rate will change depending on the progress of dry distillation, and sufficient unburned gas will enter the combustion chamber. Once introduced, even if combustion in the burner 5 is stopped, combustion can be continued using only the introduced dry distilled gas - at this time, the CO amount of the changeover switch on the gas combustion plate increases and the variable If the resistor RLf is selected appropriately, 6) will be energized, its contact rx1 will be closed, and the timer gate will be activated.
L10f is excited. Timer〇, timer〇 contact T2
closes, , the timer @ coil is energized to TI/1, and after the set number of minutes, O
Contact TI closes, energizes the coil of relay ■, and □
The contact Xl'A is closed and the contact XIB is opened, and no input is input to the operation terminal of the burner control panel, and the burner stops combustion.The amount of raw gas generated in the dry distillation furnace is unstable in the initial stage. The increase or decrease in the amount of gas causes the so-called chattering phenomenon. Timers 〇 and 〇 are provided to prevent the combustion from stopping, and the combustion of the burner is stopped only when the dry distilled gas is stably and sufficiently delivered. As the amount of unburned gas decreases and the excitation force of the temperature inside the combustion chamber is insufficient, contact x1^ is opened and contact The gas combustion device according to the present invention does not require a special burner, has a combustion chamber of a size corresponding to the amount of gas, and can blow air with a multi-air control valve I, adjusting the amount of air blown. By adjusting the amount according to the combustion stage, ideal combustion conditions can be maintained, and not only dry distilled gas but also other types of gas fuel can be used. Particularly when the amount of combustion gas introduced changes,
As soon as the amount of combustion gas introduced decreases and it becomes difficult to continue self-combustion, the ignition burner is completely combusted, the unburned gas is combusted, and the unburned gas exits the outlet and continues to follow. This is an extremely effective invention that prevents fuel from accumulating in heat exchangers, etc., exploding for some reason, or becoming unburned black smoke and being emitted from the chimney.
