Abstract
Official abstract text for this publication.
A modular furnace, in particular for the oxidative stabilization of a carbon fiber starting material comprising a cuboidal furnace chamber, on the upper face of which first deflecting rollers are arranged in a mutually spaced and parallel manner and on the lower face of which second deflecting rollers are arranged in a mutually spaced and parallel manner such that the carbon fiber starting material runs upwards and downwards in a laterally adjacent and slightly spaced manner so as to meander vertically in the area of the furnace chamber. A carbon fiber inlet locking device and a carbon fiber outlet locking device are provided on the upper face of the furnace chamber, and an air guiding device is connected to the furnace chamber. A supply air portion of the air guiding device is connected to a vertical air inlet side of the furnace chamber, and a discharge air portion of the air guiding device is fluidically connected to a furnace chamber vertical air outlet side opposite the vertical air inlet side. The air guiding device has an air drive device between the supply air portion and the discharge air portion.

Opening claim text (preview).
The invention claimed is: 1. A modular furnace comprising a rectangular-block shaped furnace chamber, first deflection rollers being disposed so as to be mutually spaced apart and mutually parallel on the upper side of the furnace chamber, and second deflection rollers being disposed so as to be mutually spaced apart and mutually parallel on the lower side of the furnace chamber in such a manner that the carbon thread starting material in the furnace space of the furnace chamber runs side-by-side and mutually slightly spaced apart in a meandering vertical up-and-down manner, a carbon thread entry lock installation and a carbon thread exit lock installation provided on the upper side of the furnace chamber, an air guiding installation which by way of an intake air portion is connected to a vertical air entry side of the furnace chamber and by way of an exhaust air portion is connected in fluidic terms to a vertical air exit side of the furnace chamber that is opposite the vertical air entry side being connected to the furnace chamber, and the air guiding installation having an air driving installation between the intake air portion and the exhaust air portion and wherein the modular furnace comprises an air exchange installation which has a fresh air inlet and an exhausting air outlet and in that at least one gas sensor is operatively linked to the fresh air inlet and to the exhaust air outlet of the air exchange installation which is provided in the exhaust air portion and/or in the intake air portion of the air guiding installation. 2. The modular furnace as claimed in claim 1 , wherein each first and/or each second deflection roller is in each case connected to one drive installation. 3. The modular furnace as claimed in claim 1 , wherein a lid space in which the first deflection rollers are located is provided on the upper side of the furnace chamber, in that a base space in which the second deflection rollers are located is provided on the lower side of the furnace space, and in that the lid space has the carbon thread entry lock installation and the carbon thread exit lock installation. 4. The modular furnace as claimed in claim 1 , wherein a screen installation is provided between the vertical air entry side of the furnace chamber and the intake air portion of the air guiding installation, and/or between the vertical air exit side of the furnace chamber and the exhaust air portion of the air guiding installation. 5. The modular furnace as claimed in claim 4 , wherein the screen installation is provided for homogenizing the air stream in the furnace chamber and is configured as a particle retention installation. 6. The modular furnace as claimed in claim 1 , wherein the air driving installation has at least one cross-flow fan. 7. The modular furnace as claimed in claim 6 , wherein the at least one cross-flow fan is connected to a diffusor which forms a part-portion of the intake air portion of the air guiding installation. 8. The modular furnace as claimed in claim 1 , wherein the intake air portion and the exhaust air portion of the air guiding installation are in each case configured so as to be bent, and air directing elements are provided in the region of the respective bend. 9. The modular furnace as claimed in claim 1 , wherein at least one flow rate sensor is provided in the intake air portion and/or in the exhaust air portion of the air guiding installation. 10. The modular furnace as claimed in claim 1 , wherein a heating installation is provided in the intake air portion of the air guiding installation. 11. The modular furnace as claimed in claim 10 , wherein the air driving installation has at least one cross-flow fan, wherein the at least one cross-flow fan is connected to a diffusor which forms a part-portion of the intake air portion of the air guiding installation and wherein the heating installation is provided downstream of the diffusor. 12. The modular furnace as claimed in claim 10 , wherein the heating installation as a zonal heating installation has at least two heating elements which are disposed so as to be mutually spaced apart and vertically on top of one another. 13. The modular furnace as claimed in claim 12 , wherein temperature sensors which are disposed vertically on top of one another so as to correspond to the vertical positions of the heating elements are mutually spaced apart in the furnace space, wherein the respective at least one temperature sensor is connected to the associated at least one heating element of the respective temperature zone. 14. The modular furnace as claimed in claim 1 , wherein the modular furnace is surrounded by a thermal insulation.
