Collaborate and on the interflow path 21a (21b) that is connected to heat storage unit 12a (12b), above-mentioned nitrogen treatment portion 20a is set in path 5
When (20b), as shown in Fig. 2, the bypass of nitrogen treatment portion 20a (20b) can be provided around on above-mentioned interflow path 21a (21b)
Path 22a (22b), and combustion air and/or burning waste gas to passing through above-mentioned bypass path 22a (22b) flowing are set
The flow-regulating components 23a (23b) that is adjusted of amount.
Then, as shown in Fig. 2, being closed in the open and close valve 5a (5b) set on exhausting waste gas path 5 and supplying road set on air
In the state that the open and close valve 3a (3b) of diameter 3 is opened, using above-mentioned flow-regulating components 23a (23b), to passing through above-mentioned nitrogen treatment
Portion 20a (20b) flowing combustion air flow and across bypass path 22a (22b) flowing combustion air flow
It is adjusted, so as to suitably being carried out by the oxygen concentration in heat storage unit 12a (12b) and the combustion air that is guided
Adjust, to carry out burning appropriate, and even if the nitrogen adsorption material y in nitrogen treatment portion 20a (20b) air drag
Very big, combustion air is difficult that can also utilize flow-regulating components 23a in the case of flowing through nitrogen treatment portion 20a (20b)
(23b) is to passing through the flow of the combustion air of bypass path 22a (22b) flowings to be adjusted, so that suitable burning be used
Air is guided to heat storage unit 12a (12b) for burning.
In addition, regenerative burner device as shown in Figure 2 above is such, when the setting of above-mentioned interflow path 21a (21b) around
The bypass path 22a (22b) of nitrogen treatment portion 20a (20b) is crossed, and is arranged to passing through above-mentioned bypass path 22a (22b) to flow
Combustion air and/or burning waste gas the flow-regulating components 23a (23b) that is adjusted of amount in the case of, such as Fig. 3
It (A), can be in the nitrogen treatment portion 20a (20b) set on interflow path 21a (21b), in bypassed path shown in (B) of Fig. 3
At in the part that 22a (22b) is surrounded, the feed direction downstream side position of combustion air, setting makes from nitrogen treatment portion 20a
(20b) towards heat storage unit 12a (12b) combustion air by and not by burning waste gas from heat storage unit 12a (12b) to nitrogen
The check-valves 24a (24b) of processing unit 20a (20b) guiding.
In this way, when more being leaned at the feed direction downstream side position of combustion air than nitrogen treatment portion 20a (20b), if
Set make from nitrogen treatment portion 20a (20b) towards the combustion air of heat storage unit 12a (12b) by and stop burning waste gas
In the case of the check-valves 24a (24b) guided from heat storage unit 12a (12b) to nitrogen treatment portion 20a (20b), such as (A) institute of Fig. 3
Show, when the open and close valve 5a (5b) set on exhausting waste gas path 5 is closed and is beaten set on the open and close valve 3a (3b) of air feed path 3

In the state that the open and close valve 3a (3b) of gas feed path 3 is closed, by the burning waste gas in heating furnace 1 to heat storage unit 12a (12b)
Guiding, after so that the heat of burning waste gas is stored in the heat-storing material x for being housed in heat storage unit 12a (12b), utilizes above-mentioned exhaust apparatus
4, in the case that above-mentioned burning waste gas is pumped to exhausting waste gas path 5, burning waste gas is prevented by above-mentioned check-valves 24a (24b),
It will not be guided to nitrogen treatment portion 20a (20b), but the check-valves 25a only by being set to above-mentioned bypass path 22a (22b)
(25b) is guided to exhausting waste gas path 5.
Moreover, in this case, utilizing what is guided above by bypass path 22a (22b) and to exhausting waste gas path 5
The flowing of burning waste gas, also can be by suction in above-mentioned nitrogen treatment portion 20a (20b) at negative pressure, to make absorption using the decompression
It is detached from the nitrogen of nitrogen adsorption material y, is guided simultaneously to flue 6 by exhausting waste gas path 5 together with above-mentioned burning waste gas
Discharge.
It is the nitrogen treatment portion 20a that will contain nitrogen adsorption material y in addition, in above-mentioned each regenerative burner device
(20b) be set between air feed path 3 and exhausting waste gas path 5 and heat storage unit 12a (12b), but can with as shown in figure 5,
In the heat storage unit 12a (12b) for containing heat-storing material x, setting contains the nitrogen treatment portion 20a of nitrogen adsorption material y
(20b)。
In addition, in above-mentioned each regenerative burner device, in order to make the nitrogen for being adsorbed in nitrogen adsorption material y suitably take off
From and make burning waste gas pass through exhausting waste gas path to be discharged, using exhaust apparatus 4, burning waste gas is pumped to exhausting waste gas road
Diameter 5, but exhausting waste gas path 5 is being acted on using the suction force generated by the stack effect of flue 6, to make to be adsorbed in nitrogen
The nitrogen of sorbing material y is suitably detached from, in the case of so that burning waste gas is passed through exhausting waste gas path 5 and being suitably discharged, and
It is not necessarily intended to setting exhaust apparatus 4.
In addition, being that heat accumulating burner 10a, 10b are oppositely arranged but it is also possible to be side by side in the present embodiment
Other settings such as setting.
