The propagation combustion device uses a combustion method in which the cycle of air supply and exhaust, ignition, combustion, and extinguishing is continuously repeated in the straight-tubular combustion chamber, and the flame front propagates in each cycle. A very small amount of unburned gas may remain at both ends of the tip ignition part A' and the proximal extinguishing part B' during ignition and extinguishing, and incomplete combustion may occur due to a drop in flame temperature. Products etc. also remain. However, in the conventional propagation combustion apparatus described above, no measures are taken to treat residual unburned gas, etc., so the combustion exhaust gas released from the exhaust pipe 7' to the outside contains toxic gases such as unburned gas.

In order to achieve the above object, the propagation combustion device according to the present invention has air supply and exhaust air in a straight pipe combustion chamber.
In a combustion type propagation combustion device in which the cycle of ignition, combustion, and extinguishing is repeated continuously and the flame front propagates, a heat-resistant wire is installed on the downstream side of the ignition source, such as a nichrome wire, provided at the tip ignition part of the straight-tubular combustion chamber. An oxidation filter made of a material such as a catalyst such as platinum supported on a carrier such as ceramic foam, which also has corrosion resistance, is provided, and when the combustion exhaust gas passes through the oxidation filter, it removes the undesirable substances contained in the combustion exhaust gas. It is designed to oxidize and remove toxic gases such as combustion gas before discharging them.

ーナが適する。 A second aspect of the present invention is to provide an afterburner in the vicinity of the oxidation filter for heating the oxidation filter to a degree necessary for its activation, so that the afterburner quickly and reliably heats the oxidation filter to the optimum temperature for its activation. This enables more efficient oxidation treatment of toxic gases such as unburned gas. Note that if the heating temperature of the oxidized filter by the afterburner is too high, it cannot be activated, and the oxidized filter is severely burned out, and even if the heating temperature is too low, it cannot be activated. Therefore, in order to obtain the optimum heating temperature for activating the oxidation filter, a surface combustion type radiation burner is suitable as the afterburner.

The propagation combustion device of the invention of claim 1 configured as described above continuously repeats the cycles of air supply and exhaust, ignition, combustion, and extinguishing, and the air supply operation in the next cycle burns the previous cycle. The exhaust gas is pushed out and released, but when this combustion exhaust gas is released, it passes through an oxidation filter installed on the downstream side of the ignition source, thereby removing toxic gases such as unburned gas contained in the combustion exhaust gas. Since the gas is completely oxidized, exhaust gas containing toxic gases such as carbon monoxide is not released outside the device, and the exhaust gas can be cleaned.

Furthermore, the oxidation treatment of toxic gases such as unburned gases contained in combustion exhaust gas can be performed more efficiently.

る。 In the embodiment of claim 1 shown in FIGS. 1 and 2, 1 is a straight tube-shaped combustion chamber, and the upstream side thereof, that is, the proximal extinguishing part B, rapidly changes the flow velocity of the flame flow during extinguishing. A constricted portion 5 is integrally formed by squeezing or the like to create a barrier and ensure fire extinguishment, and a mixing chamber 6 is continuously expanded and formed on the upstream side of the constricted portion 5.
Reference numeral 2 denotes an ignition source disposed downstream of the straight tube-shaped combustion chamber 1, that is, at the tip ignition site A, and uses, for example, a nichrome wire, an igniter, a ceramic heater, a pilot burner, or the like. Reference numeral 3 denotes an oxidation filter provided on the downstream side of the ignition source 2. When the combustion exhaust gas from the combustion chamber 1 passes through the oxidation filter 3, the oxidation filter 3 is heated by the exhaust heat, and at the same time, it is added to the combustion exhaust gas. This process oxidizes and removes the unburned gas and other toxic gases it contains.
A suitable oxidation filter 3 is one in which a catalyst is supported by any means on a carrier having heat resistance, corrosion resistance, and a certain level of air permeability (permeability). for example,
A plate of a certain thickness is made by supporting heat-resistant and corrosion-resistant cordierite (2MgO.5SiO 2 ′.2Al 2 O 3 ) with platinum (H 2 P 6 cl 6 ) as a catalyst by an impregnating method. It is preferable to use a honeycomb-shaped or foam-shaped vent hole. If the oxidation filter 3 is provided with a deodorizing property by adding perovskite or the like, it also has a deodorizing effect and is useful in practice.

By making it possible to quickly and reliably heat the filter 3 to the optimum temperature for activation, it is possible to quickly activate the oxidation filter 3 and to more efficiently remove toxic gases such as unburned gas contained in combustion exhaust gas. This allows for oxidation treatment.

る。 Propagation combustion equipment consists of air supply and exhaust, ignition, combustion,
The extinguishing cycle is repeated continuously, and each part of the combustion chamber 1 is heated evenly by the flame front propagating inside the combustion chamber 1 for each cycle, so the heat is radiated evenly to each part and uneven heating is prevented. For example, along with its extremely high thermal efficiency,
It is extremely useful when used as a heating source for various gas-burning equipment such as snow melting equipment for roads in cold regions (road heating) or commercial fryers. Therefore, the combustion mechanism is such that a certain amount of fuel gas from the gas nozzle 8 and a certain amount of primary air from the primary air intake port 9 are supplied to the mixing chamber 6 and mixed, and the mixed air-fuel mixture is transferred to the mixing chamber 6. The fuel is supplied into the straight-tubular combustion chamber 1 through the narrowed part 5, flows from the upstream side to the downstream side within the combustion chamber 1 (see dotted arrow b in the figure), and its tip reaches near the ignition site A at the tip. Then, the ignition site A
This is ignited by an ignition source 2 located nearby. When the tip of the air-fuel mixture is ignited, the air-fuel mixture starts to burn from the tip, and the flame flows from the downstream side to the upstream side in the combustion chamber 1 (see the solid line arrow a in the figure), and the flame propagates to the combustion chamber 1. Heat each part evenly.
When the end of the flame flow reaches near the narrowed part 5 of the proximal extinguishing part B, the narrowed part 5 creates a barrier to dam the flame flow and causes a sudden change in its flow velocity, ensuring that the flame is extinguished. The flame propagation combustion operation is repeated continuously, in which the combustion exhaust gas in the combustion chamber 1 is pushed downstream and released from the exhaust pipe 7 to the outside of the combustion chamber. be.

た。 In the above flame propagation combustion operation, experiments have shown that, for example, when the length of the straight tube combustion chamber 1 is 10 m, one cycle of air supply, exhaust, ignition, combustion, and extinguishing takes approximately 30 to 60 seconds. If the input is 1000Kcal/h, the temperature will be approximately 100℃ to 120℃.
A heating temperature of 100% was obtained equally from each part of the combustion chamber 1.

点火源にも併用できるものである。 In a flame propagation combustion operation in which the cycles of air supply and exhaust, ignition, combustion, and extinguishing are repeated continuously, the combustion exhaust gas from the previous cycle is used during the air supply operation to supply the mixture in the next cycle to the combustion chamber 1. The supplied air is pushed out and released from the exhaust pipe 7 to the outside of the device.In this invention, since the oxidation filter 3 is provided on the downstream side of the ignition source 2 provided at the tip ignition site A of the combustion chamber 1, the combustion As the exhaust gas passes through the oxidation filter 3, the oxidation filter 3 is heated, and at the same time, toxic gases such as unburned gas and products contained in the combustion exhaust gas are oxidized to clean the exhaust gas. Exhaust gas containing toxic gases such as carbon monoxide will not be released outside the vessel. Furthermore, if the oxidation filter 3 is heated to the optimal temperature for activation by the afterburner 4, the activation of the oxidation filter 3 becomes rapid, and the oxidation treatment of toxic gases such as unburned gas contained in the combustion exhaust gas becomes possible. This is useful in practice because it can be done more efficiently. In addition, afterburner 4
The purpose of this is to heat the oxidation filter 3 to the optimum temperature for its activation, but in actual use, due to the combustion decomposition effect of toxic gases such as unburned gas contained in the combustion exhaust gas. It also has a burnout oxidation function, and can also be used as an ignition source if the afterburner 4 is installed in front of the oxidation filter 3 and near the ignition site A.
この発明は、以上説明したように構成されてい
