Description

Eco-Friendly Cosmetic Incinerator {Enviroment-Frendly Type Cremator}

The present invention relates to an environment-friendly cosmetic incinerator for supplying ashes by incineration of fluid at a high temperature by using an incinerator burner device used to incinerate an incinerator.

More specifically, the combustion air flow path of the burner apparatus has a multi-stage structure to control (lower) the temperature of the flame, and in particular, the exhaust gas discharged from the main combustion chamber or the reburn chamber of the cremation incinerator is supplied to the combustion air supplied to the burner apparatus. By using a mixed recycle, it ultimately relates to an eco-friendly cosmetic incinerator which suppresses the generation of nitrogen oxides (hereinafter referred to as 'NOx') generated during combustion incineration of the cosmetic incinerator, and thus is used more environmentally.

As the social environment changes rapidly through the urban concentration and industrialization of the population, the funeral culture, which has been dependent on the burial culture in accordance with conventional Confucian customs, has also changed its perception, and recently it is gradually changing into a cremation culture.

In addition, the development of the technology has been made in the incinerator which can cremate a human body (or the corpse of an animal), and most of them are being developed in an environmentally friendly direction with energy saving.

On the other hand, the known shape of the cremation incinerator is a bogie-type cremation incinerator mainly distributed in the Orient, which emphasizes the dignity of the body in the cremation process in terms of equipment characteristics. There is a form (western form), and some other loss stall method is adopted.

     Such a cremation incinerator facility includes a main combustion chamber in which cremation is performed by directly using a gas or a diesel gas burner for the body and a pipe, a reburn chamber for reburning unburned dust contained in the exhaust gas generated during cremation prior to external discharge, and It consists of an exhaust gas treatment facility that removes pollutants contained before releasing boil exhaust gas into the stack.

In the case of a conventional bogie-type cremation incinerator, the body and pipes are mounted on the trolley and moved to the main combustion chamber of the cremation incinerator to burn incineration by operation of the combustion burner. After cooling the main combustion chamber temperature to a certain temperature, take out the trolley out of the body to supply the bones and collect the bones.

For example, as shown in FIG. 1, the conventional bogie-type cremation incinerator 200 has a main combustion chamber 210 having a burner 212 at a lower part of a furnace, and a reburn chamber having a burner 222 at an upper side thereof. 220 is disposed, and the exhaust gas G discharged from the reburn chamber 220 is recovered as sensible heat and used for preheating combustion air, and is discharged to the outside through a dust collector and an environmental pollution source treatment facility and a stack.

In addition, in the case of the conventional bogie type, the main combustion chamber 110 is provided with doors (unsigned) that enable the entry and exit of the bore 250 to which the incinerator, that is, the tube 240, is placed.

On the other hand, the cremation incinerator 200 of the balance method usually arranges the reburn chamber 220 in the upper portion of the main combustion chamber 210, because it is difficult to arrange the reburn chamber in the lower portion of the main combustion chamber.

However, in the case of the conventional trolley-type cremation incinerator 200, the time for which the high-temperature exhaust gas stays in the main combustion chamber 210 and the reburn chamber 220 is short, and the incinerators such as the initial pipe and the accessory are burned. In the process of instantaneous rapid combustion, there was a problem that the carbon monoxide (hereinafter referred to as 'CO') is rapidly increased as the main combustion chamber suddenly rises in temperature, and out of the processing capacity in the reburn chamber.

On the other hand, the cosmetic incinerator of the cabinet or rostol method different from the cosmetic incinerator 200 of the balance method such as pushing the tube into the interior of the cremation furnace without a separate support (bogie), and the finished ashes are tools for work. There is a difference from the balance method of FIG. 1 in that it does not use the balance as a method of collecting and processing.

For example, FIG. 2 illustrates a conventional cabinet type cremation incinerator 300. In the case of such a cabinet type, since a loan facility is not required, the reburn chamber 320 is provided under the main combustion chamber 310. The exhaust gas generated during combustion incineration is transferred from the main combustion chamber 310 to the reburn chamber 320 through the connection passage 330 to increase the residence time of the exhaust gas and discharge the same.

Therefore, in the case of the conventional cabinet-type cremation incinerator 300 as shown in FIG. 2, when the cremation of the pipe in which the body is settled by the burner 312 is performed in the main combustion chamber 310, the generated exhaust gas is lowered. Since it is discharged to the outside through the stack through the reburn chamber 320, the lower body temperature of the lower body of the main combustion chamber 310 is maintained well by the sensible heat of the exhaust gas, if necessary, a separate burner (not shown) in the reburn chamber 320 ), And the environmental pollution source is removed more efficiently than the trolley-type cremation incinerator of FIG.

However, in the cremation incinerators 200 and 300 of the conventional bogie or cabinet method of FIGS. 1 and 2, the problem that environmentally harmful substances such as CO or NOx are discharged is not solved.

For example, in the case of burners used in the known conventional cremation incinerators 200 and 300, a pre-mixed burner which normally mixes and burns fuel (LNG or LPG) and combustion air is Mostly.

Therefore, since the supply of heat through combustion is performed by constantly adjusting the mixing ratio (air-fuel ratio) of the air-to-fuel of the burner, most of the combustion air is supplied at an air-fuel ratio based on complete combustion, and exhibits relatively high combustion efficiency. It has a high flame temperature, and accordingly there was a problem that a large amount of NOx occurs.

In particular, in the case of the bogie-type cremation incinerator 200 of FIG. 1, since the residence time of the exhaust gas is short because there is no reburn chamber at the bottom, it is difficult to remove environmentally harmful substances through secondary combustion in the reburn chamber. Therefore, in the case of the bogie, the exhaust gas contained excessive NOx, which easily exceeded the environmental regulations.

In addition, in the cabinet-type makeup incinerator 300 as shown in FIG. 2, since the operating temperatures of the main combustion chamber and the reburn chamber must be maintained at 850 ° C. or higher, a large amount of NOx and unburned gas in the exhaust gas are similar to those of the combustion-type cosmetic incinerator. Minutes occurred.

Therefore, recently, lime is injected into the exhaust gas by using a dry sorbent injection system (76 in FIG. 7) installed in an exhaust gas discharge line (see 60 in FIG. 7) of a cosmetic incinerator. Sox, HCl) and NOx may be treated using activated carbon. However, there is no effective method for effectively reducing NOx, which is an environmental pollutant emitted from a cosmetic incinerator.

The present invention has been proposed in order to solve the above-mentioned conventional problems, and an object of the present invention is to control (lower) the temperature of the flame by using the combustion air flow path of the burner device in a multi-stage structure, and in particular, the main combustion chamber or replay of the incinerator By mixing and using the exhaust gas discharged from the combustion chamber to the combustion air supplied to the burner device, it ultimately suppresses the generation of NOx generated during combustion incineration of the cremation incinerator, thereby providing a more environmentally friendly eco-friendly cremation incinerator. There is.

As a technical aspect for achieving the above object, the present invention, the main combustion chamber in which the incinerator is incinerated; And an incinerator burner device provided in any one or both of the main combustion chamber and the reburn chamber.
The reburn chamber is arranged in communication with the lower part of the main combustion chamber, and an exhaust gas passage having an opening and closing means is installed between the main combustion chamber and the reburn chamber, and an exhaust gas outlet is provided at an upper side of the main combustion chamber and one side of the reburn chamber. To provide an eco-friendly cosmetic incinerator.

According to the present invention, the combustion air flow path of the burner device has a multi-stage structure to control (lower) the temperature of the flame, and in particular, the combustion gas supplied to the burner device to exhaust gas discharged from the main combustion chamber or the reburn chamber of the incinerator. By using the mixture in the air, it is ultimately to provide the effect of suppressing the generation of NOx generated during the combustion incineration of the cremation incinerator, thereby providing a more environmentally friendly cremation incinerator.

Hereinafter, a preferred embodiment of the present invention according to the accompanying drawings in detail as follows.

However, in the following the incinerator burner device-related configuration according to the present invention will be described with reference numerals of 100 units, eco-friendly cosmetic incinerator including the incinerator burner described by the reference numerals of 10 units, but the burner device ' 100 ', eco-friendly cosmetic incinerator is indicated by the reference numeral' 1 '.

First, in Figures 4 to 6, the eco-friendly cosmetic incinerator 1 according to the present invention is shown in side, front and part planar structure, respectively.

For example, the eco-friendly cosmetic incinerator 1 of the present invention is configured as a bogie type, but unlike the existing, the combustion chamber 30 of the main combustion chamber 20 has a combustion chamber 30 of FIG. In comparison, the residence time of the exhaust gas is increased in the reburn chamber, thereby enabling suppression of soot, CO, or NOx through furnace heating, combustion incineration, and exhaust gas reburn.

In other words, the eco-friendly cremation incinerator (1) of the present invention is more advantageous in Korea, where the funeral form is important by the long Confucian culture, and the cabinet of FIG. It is an embodiment feature that the structure is made of a mixing method.

For example, as shown in Figure 4, the main combustion chamber 20 of the eco-friendly cosmetic incinerator 1 of the present invention, the main combustion burner, that is, the burner device 100 of the present invention is installed on the outlet side is charged The incinerator (10) is, for example, a place where the incineration of the woodwind where the body is placed.

The main combustion chamber 20 includes the doors 26a and 26b provided for the furnace charging and extraction of the incinerator 10, in particular, the pipe which is the incinerator between the charging and extraction doors. The incinerator moving rollers 24 for smoothly charging and extracting are installed.

Therefore, the main combustion chamber 20 of this invention is comprised with the bogie type which can load and extract a tube easily.

Next, as shown in Figures 4 to 6, in the eco-friendly cosmetic incinerator 1 of the present invention, the reburn chamber 30 is arranged in the lower portion of the main combustion chamber 20, but the peripheral edge through the exhaust gas passage (50) The exhaust gas of the vane flows into the reburn chamber 30.

In particular, as shown in Figure 6, in the cremation incinerator of the present invention, since the reburn chamber 30 includes multiple exhaust gas induction furnaces 32, the main combustion chamber 20-> exhaust gas passage 50 The residence time of the exhaust gas G introduced through is increased, which facilitates maintaining the furnace temperature.

Therefore, in the case of the eco-friendly cosmetic incinerator 1 according to the present invention, the main combustion chamber is made of the existing bogie system, and the reburn chamber is made of the existing cabinet method so as to take advantage of each advantage at the same time.

At this time, as shown in Figure 4 and 5, the exhaust gas passage for communicating the main combustion chamber and the reburn chamber in order to put the reburn chamber in the bogie type and the lower portion of the eco-friendly cosmetic incinerator 1 of the present invention. 50 is extended downward from both sides of the furnace body of the main combustion chamber is connected to both sides of the reburn chamber.

Therefore, in the case of the present invention, since it flows to the reburn chamber through the exhaust gas passage 50 on both sides of the furnace body of the main combustion chamber 20, the reburn chamber flows smoothly.

Meanwhile, although schematically illustrated in FIG. 5, the exhaust gas passage 50 is horizontally moved in the passage opening / closing means 40, that is, the exhaust gas passage 50, to open or block the inlet of the reburning chamber of the exhaust gas as necessary. And an opening and closing plate.

The passage opening and closing means of the opening and closing plate may be connected to a drive cylinder (not shown) provided horizontally outside the furnace body to open and close the passage opening portion.

Therefore, since the exhaust gas is continuously generated during the combustion incineration in which cremation proceeds, the opening and closing means 40 opens the exhaust gas passage 50 so that the exhaust gas G continuously flows into the reburn chamber 30, After the makeup is completed, the exhaust gas passage 50 is blocked to block the main combustion chamber reverse inflow of the exhaust gas in the reburn chamber.

6, the multiple exhaust gas induction furnaces 32 of the reburn chamber 30 may increase the exhaust gas residence time as compared with the cremation incinerator 300 of FIG. 2, and reference numeral 34 of FIG. As a result, the exhaust gas on the induction furnace is temporarily suppressed to increase the residence time of the exhaust gas.

Therefore, in the eco-friendly cosmetic incinerator 1 described above, the exhaust gas G generated in the main combustion chamber 20 at the time of combustion incineration is discharged through the exhaust gas passage 50 when the opening and closing means 40 is operated. The exhaust gas is introduced into the reburn chamber 30, and the exhaust gas is discharged through one side exhaust port 30a that meets the induction path through the multiple exhaust gas induction path 74.

On the other hand, as shown in Figure 3, the incinerator burner device 100 of the present invention described in detail in the reburn chamber 30 in the eco-friendly cosmetic incinerator 1 of the present invention is provided as a reburn burner exhaust exhaust By reburning the gas, environmental pollutants such as CO or NOx are removed.

Next, FIG. 3 illustrates the structure of the incinerator burner device 100 used in the main combustion chamber 20 and / or the reburn chamber 30 of the eco-friendly cosmetic incinerator 1 according to the present invention shown in FIG. 4. .

That is, as shown in Figure 3, the incinerator burner device 100 of the present invention is a burner that is connected to the apparatus main body 110 and the apparatus main body 110, the fuel is supplied to generate a flame (F) And a combustion fluid flow path 130 or 140 of a plurality of stages configured to surround the nozzle unit 120 and the burner nozzle unit 120 through the apparatus main body and to be opened at one side of the burner nozzle unit to supply the combustion fluid. There is an embodiment feature to the inclusion.

Therefore, when LNG or LPG, which is fuel, is supplied to the burner nozzle unit 120, the fuel is ignited to generate a flame, and the multi-stage combustion fluid flow paths 130 and 140 are burned for combustion through pipes 132 and 142. A fluid, for example, combustion air or exhaust gas generated in the cosmetic incinerator 1 as shown in FIG. 7 or a combustion fluid mixed with these is supplied.

At this time, the apparatus body 110, as shown in Figure 3, the cylindrical body 110b, 110c surrounding the fixed body (110a) and the lance constituting the first and second multi-stage combustion fluid flow path (130, 140) ), And a fixture 110d for fixing to a facility (for example, a cremation incinerator wall).

In addition, the pipes 132 and 142 connected to the first and second combustion fluid flow paths 130 and 140 are supplied to the combustion air supply line 66 or the exhaust gas branch of the outside air, as shown in FIG. 7. May be replaced by line 64.

In addition, the connection pipe 122 connected to the burner nozzle unit 120 in FIG. 3 may be replaced with the fuel supply pipe 69 of FIG. 7.

At this time, in the incinerator burner device 1 of the present invention, preferably the burner nozzle unit 120, the first combustion fluid flow path 130 and the second combustion fluid flow path 140 are sequentially surrounded. It is a structure.

Therefore, since the incinerator burner device 1 of the present invention surrounds the burner nozzle unit 120 but has the first and second combustion fluid flow paths 130 and 140 having the flame (F) generating portion open therein, they are formed in multiple stages. The flame may be adjusted by adjusting the amount of combustion fluid, ie, combustion air, supplied to the first and second combustion fluid flow paths 130 and 140.

For example, conventional burners used in cremation incinerators have a pre-mixed burner structure that premixes and combusts fuel and combustion air, as described above, in which case premixing is based on complete combustion. Since the flame temperature is formed at a high temperature, a large amount of NOx is inevitable.

However, in the incinerator burner device 100 according to the present invention as shown in FIG. 3, the first and second combustion air flows supplied to the first and second multi-stage combustion fluid flow paths 130 and 140 are primarily adjusted to adjust the amount of combustion air. By encouraging incomplete combustion in the burner nozzle unit, the temperature of the flame F can be lowered and complete combustion can be realized in the course of passing through the combustion chamber of the eco-friendly cosmetic incinerator of the present invention.

In particular, as shown in FIG. 7, when the exhaust gas generated in the incinerator is mixed with the combustion air and recycled, the flow rate of the entire combustion fluid is increased to increase the flame length, but includes the exhaust gas circulated in the burner device. Since the actual oxygen content of the combustion air is lowered on the contrary, the combustion temperature of the fuel is incomplete, and the temperature of the flame is lowered, which enables the burner device 1 of the present invention to reduce NOx.

For example, in the incinerator burner device 1 of the present invention, when LNG or LPG is supplied to the nubber nozzle unit 120, the first combustion fluid flow path 130 is provided through the first and second combustion fluid flow paths in the vicinity thereof. When only 40% of the theoretical combustion air is supplied and 60% is supplied to the second combustion fluid flow path 140, the flame F temperature may be lowered.

In addition, as described above, when the exhaust gas is mixed with the combustion air, the oxygen potential for determining the flame temperature in the burner device is lowered, so that the temperature of the flame can be further lowered. Approximately 60% or more of the NOx concentration contained in the exhaust gas is reduced.

That is, the incinerator burner device of the present invention supplies the combustion fluid (combustion air, exhaust gas, or a mixture thereof) of the multistage in different flow paths to the multi-stage flow path, so that the flame (F) generated in the burner nozzle unit 120 is ignited. It is possible to lower the temperature of the solution and ultimately realize the reduction of NOx.

Therefore, the environmentally friendly makeup incinerator 1 of the present invention using the incinerator burner device of the present invention as shown in FIG. 3 can also reduce NOx, which is to provide a more environmentally friendly cosmetic incinerator.

Next, Figure 7 shows the overall configuration of the eco-friendly incinerator 1 including the incinerator burner device 100 of the present invention as described above.

However, the furnace itself structure of the cremation incinerator 1 has already been described above with reference to FIGS. 4 to 6, and the description thereof is simplified here, and a combustion fluid for operating the burner device, for example, combustion air, exhaust gas or the like. The structure provided with the lines for these mixed supply is demonstrated.

First, as shown in FIGS. 7 and 8, in the eco-friendly cosmetic incinerator 1 of the present invention, the main combustion chamber 20 and the reburn chamber 30 are provided with the burner device 100 of the present invention. 3, LNG or LPG supply pipe 69 is connected to the nozzle nozzle 120 of the incinerator burner 1 so that fuel is supplied to the lance and ignited to generate flame (F).

Next, an exhaust gas branch supply branched from the incinerator exhaust gas discharge line 60 is supplied to the first and second multi-stage combustion fluid flow paths 130 and 140 of the incinerator burner device 100 provided in the cremation incinerator of the present invention. Any one or both of the line 64 and the combustion air supply line 66 for supplying the outside air are connected to each other so that the combustion air and the exhaust gas are supplied alone or in combination.

That is, the discharge lines 60a and 60b respectively connected to the main combustion chamber discharge port 20a and the reburn chamber discharge port 30a are combined with the incinerator exhaust gas discharge line 60 and discharged.

7 and 8, the exhaust gas branch supply line 64 may be connected to and supplied to the exhaust fan 62 provided in the incinerator exhaust gas discharge line 60 or downstream thereof.

In addition, such an exhaust gas branch supply line 64 passes directly through the heat exchanger 68 to the second combustion fluid flow path 140 and immediately passes through the second branch pipe 64a and the heat exchanger without first passing through the heat exchanger. It may be divided into a first branch pipe 64b connected to the combustion fluid flow path 130.

In addition, as shown in FIG. 7, combustion air of outside air is supplied to the combustion air supply line 66 through the blowing unit 66a, and the supply line 66 is connected to the exhaust gas branch supply line 64.

7 illustrates a case where the combustion air and the exhaust gas, which are outside air, are mixed and supplied to the burner device 100, and the exhaust gas branch supply line 64 and the combustion air supply line 66 are each independently. Of course, it can be connected to the burner device (100).

In addition, it is also possible that the combustion air supply line 66 is mainly used and the exhaust gas branch supply line 64 is connected to the combustion air supply line 66.

Meanwhile, as shown in FIGS. 7 and 8, a second branch pipe 64a is passed through a heat exchanger 68 of an exhaust gas branch supply line 64 in the second combustion fluid flow path 140 of the incinerator burner device 100. In this case, when the burner device is operated, a mixed fluid of combustion air and uncooled exhaust gas without passing through a heat exchanger is supplied from the first combustion fluid flow path 130, and the second combustion fluid flow path 140 is cooled through a heat exchanger. The mixed fluid in which combustion air is mixed with the exhaust gas is supplied.

Accordingly, since the second combustion fluid flow path 140 is supplied with a fluid having a lower temperature than the first combustion fluid flow path, the flame temperature is lowered, which in turn enables the reduction of NOx.

On the other hand, as shown in Figure 7, the exhaust gas branch supply line 64 and the combustion air supply line 66 may be provided with flow control valves 65, 67, respectively, such a flow control valve ( 66 and 67 are cosmetics associated with a gas meter 80 (CO or oxygen meter) connected with an exhaust gas discharge pipe 82 connected with an exhaust gas passage 50 of the cosmetic incinerator 1 as shown in FIG. 9. In conjunction with the facility control unit (C) of the incinerator, while controlling and operating in real time, the flow rate of combustion air, exhaust gas or a mixed fluid thereof supplied to the burner device 100 may be controlled.

In addition, as illustrated in FIG. 7, the blower 62 of the exhaust gas discharge line 60 and the blowing unit 66a of the combustion air supply line 66 may also be controlled to operate in conjunction with the controller C.

And, as shown in Figure 8, the flow rate control valve 69a provided in the fuel supply pipe 69 can also be controlled to operate in conjunction with the control unit (C).

8 illustrates a line connection configuration of the burner device 100 when exhaust gas is used as combustion air. However, FIG. 8 shows various related components, for example, a pressure control valve, a safety valve, a flow meter, etc., which are not indicated by separate signs, and the components related to FIG. 7 are denoted by the same reference numerals.

That is, the first connecting pipe 64a of the exhaust gas branch supply line 64 connected to the exhaust fan 62 is connected to the second combustion fluid flow path 140 of the burner device 100 through the heat exchanger 68. The second connecting pipe 64b not passing through the heat exchanger 68 is directly connected to the first combustion fluid flow path 130 at the center of the burner device and connected to the LNG or LPG tank T. Is connected to the central burner nozzle portion 120 of the burner device 100.

Therefore, when the environmentally friendly makeup incinerator 1 of the present invention is operated through the incinerator burner apparatus 100 of the present invention as shown in FIG. 3, it is possible to reduce the temperature of the burner flame to suppress NOx generation.

At this time, the burner device supply of the exhaust gas can be adjusted according to the operation of the opening and closing valve (V) of the exhaust gas branch supply line 64 in Figure 7, the combustion air supply line 66 is connected to the front of the opening and closing valve When the on-off valve is closed, combustion air (outside air) is supplied to the burner device 100, and the operation of the heat exchanger 68 is operated when the temperature of the flame is very low to operate the second combustion fluid flow path of the burner device 100. The lower temperature combustion air may be supplied to 140.

Meanwhile, as shown in FIG. 7, the exhaust gas discharge line 60 of the eco-friendly incinerator 1 of the present invention, that is, the discharge port 20a of the main combustion chamber 20 and the discharge port 30a of the reburn chamber 30. In the exhaust gas discharge line 60, where the discharge lines 60a and 60b connected to each other are combined, the cyclone 70 collecting the exhaust gas G and the heat exchanger 72 for recovering sensible heat from the hot gas It may include a (dry) cooler 74 to cool the gas, a bag filter 78 to purify the gas, a blower 62 to which the exhaust gas branch supply line 64 is connected, and a stack 79. .

At this time, since the exhaust gas branch supply line 64 of the present invention is connected to the exhaust fan 62 (or downstream thereof) after the exhaust gas passes through the cyclone 70, the cooler 72, and the bag filter 78, The exhaust gas supplied to the actual exhaust gas branch supply line 64 is supplied while the dust is removed and cooled. This makes it possible to operate the burner unit even if it is mixed with fuel air in the burner unit.

And, between the cooler 74 and the bag filter 78, a dry Sorbent Injection System (76) for treating SOx or HCl contained in the exhaust gas is installed to process the slaked lime. It is also possible.

Therefore, in the case of the eco-friendly cosmetic incinerator of the present invention, as shown in Fig. 7, the wood pipe including the body and the auxiliary storage is put into the main combustion chamber 20 by using a trolley (feed roller 24), the lower part of the main combustion chamber The burner device 100 of the present invention in the reburn chamber is ignited to warm up to 300-400 ° C. for about 5-10 minutes to preheat the furnace.

Next, when the burner device 100 of the present invention of the main combustion chamber 20 is ignited and a flame is applied to the incinerator 10, the main combustion chamber temperature is increased to a temperature of approximately 1500 to 200 ° C. Supply minimum burner fuel volume.

At this time, the incinerator burner device 100 of the present invention, as described above, the first combustion fluid flow path 130 surrounding the burner nozzle unit 120 in FIG. 3 or the first combustion fluid flow path 130 surrounding it Burner by supplying more combustion air or exhaust gas or a mixture of these to the second combustion fluid flow path 140 than the first combustion fluid flow path 130 (about 6: 4). The temperature of flame (F) of the device is lowered to suppress the generation of NOx.

However, most preferably, during the initial incineration, only the combustion air is supplied to the incinerator burner device 100, and when the combustion is completed to some extent, the exhaust gas is mixed with the combustion air to burn the multi-stage combustion fluid flow path 130 ( 140).

In other words, when the incineration is completed, when the exhaust gas is recycled and supplied to the burner device, the exhaust gas is used, thereby saving energy and further expanding NOx removal through reliable reburning of the exhaust gas.

For example, when operating the cremation incinerator, since the NOx generation is also increased when the flame temperature of the incineration initial burner device 100 is maximized, the burner device of the present invention may appropriately lower the flame temperature to prevent this.

For example, when operating with an existing pre-mixed burner (not shown), about 120 to 160 ppm of NOx is excessively discharged, but when using the burner device 100 (see FIG. 3) of the present invention, NOx. In the case of lowering to 70 ~ 90 ppm, in particular through the exhaust gas branch supply line 64 and the combustion air supply line 66 to mix the combustion air and exhaust gas to the combustion fluid flow path (130) 140 of the burner device When fed at different rates, the NOx is lowered from 40 to 60 ppm.

While the invention has been shown and described in connection with specific embodiments so far, it will be appreciated that the invention can be varied and modified without departing from the spirit or scope of the invention as set forth in the claims below. It will be appreciated that those skilled in the art can easily know.
