PURPOSE:To burn fuel stably in a high temperature region of 600-1,000 deg.C by mounting catalyst layers, in which an oxidizing catalyst is carried to woven fabrics or nonwoven fabrics made of heat-resistant glass fibers, in a laminating shape. CONSTITUTION:Heat-insulating layers 1 in 5-30mm. layer thickness with ventilating holes 11 of 0.3-1.5mm. hole diameters directed in the inside and outside directions and catalyst layers 2 in which an oxidizing catalyst is carried to woven fabrics or nonwoven fabrics made of heat-resistant glass fibers are mounted in a laminating shape while the heat-insulating layers are positioned on the insides. The layer thickness of the heat-insulating layer 1 is brought desirably to 15-30mm.. It is preferable that ventilating holes 11 in the heat- insulating layers 1 are set to said ones while the thickness of walls 12 among each ventilating hole 11 is brought to 0.15-1.0mm. and porosity by the ventilating holes 11 occupying in the heat-insulating layers 1 is brought to 30-80% in order to compact the whole device. |
