Abstract
A catalyst device is used for a combustion apparatus. The catalyst device is provided with multiple gas flow channels. The gas flow channels are formed by corrugated sheets and flat sheets which are alternatively laminated. One of the sheets is a paper sheet mainly composed of inorganic heat-resistant fibers carrying catalyst metal dispersed thereon, and the other sheet is provided with a thin metal plate. Therefore, the combustion apparatus provided with the catalyst device has a shortened preheating time, produces a reaction heat which is uniform over all the catalyst layers and maintains the stabilized performance for a long time.
