(57) [Abstract] [Purpose] The present invention provides an excellent rotary furnace device that has the technical effect of reducing oxidation loss, the effective use of installation area, and the economic effects of construction cost and energy saving. [Structure] A plurality of sets of alternating combustion burners that alternately burn two sets of burners each having a heat storage body as one set are arranged on an inner wall of a rotary furnace. Since the alternating combustion burner is installed on the inner wall of the rotary furnace body, or by arranging it in front of and behind the upper part of the furnace body, or by arranging it on the left and right of the upper part of the furnace body, the overall size of the furnace body is reduced. It can be made small enough. In particular, if an alternating combustion burner is installed on the ceiling of the furnace body, a large space for combustion can be taken, so a large capacity burner can be installed, and even if a large capacity burner is installed, the installation space will be small. Does not grow.

On the inner wall 2 of the rotary furnace body 1, a plurality of burners A and B of the alternating combustion burner 3 are arranged. FIG. 2 is an enlarged explanatory view of a main part of the arranged alternating combustion burner 3. Figure 3
Shows an example in which the alternating combustion burner 3 is installed on the ceiling part 4 of the furnace body 1. In this case, the alternating combustion burner 3 is provided with an attachment part 5 in the front-rear direction of the ceiling part 4 and at that position. Each burner A and B of the alternating combustion burner 3 is installed. In FIG. 4, the attachment part 5 is provided in the left-right direction of the ceiling part 4, and each burner A, B is installed. In the case of FIGS. 3 and 4, the combustion gas can be attached so as to be ejected in the direction opposite to the rotation direction of the rotary hearth 6. In the case of FIG. 1 and FIG. 2 as well, each burner A is provided with an angle in the direction opposite to the rotating direction of the rotary hearth 6.

Is sucked, and this is alternately executed by operating the valve 8. Reference numeral 9 is an air supply fan, and 10 is an exhaust fan. The alternating combustion burner 3 has a characteristic that the temperature of the combustion gas rises in the ejection direction, and therefore the combustion gas is ejected toward the outer side of the furnace body with a large amount of heat radiation, as shown in FIGS. 1 and 2. The method of is very effective. Also in the cases of FIGS. 3 to 4, it is more effective to install the furnace body 1 toward the outer wall side.

And while repeating it alternately, the to-be-heated material 11 on the rotary hearth 6 is heated. The object to be heated is charged through the charging port 11,
It is taken out from the loading port 13. As described above, most of the heat quantity of the exhaust gas is recovered by the burner of its own, so that the temperature inside the furnace can be sufficiently raised and the rapid heating can be executed. Further, since the preheater and the heat exchanger are not necessary, the installation area of the furnace can be reduced by 20 to 40%. As a result, the construction cost can be reduced, and the rapid heating described above shortens the time for which the object to be heated is in the furnace, reduces the oxidation loss, and facilitates the change of the processing material. And as a synergistic effect, 50
Energy saving of 20% to 20% can be performed.
