Abstract

A mounting frame for a block-type parallel mounting of catalyst plates is provided. The block mounting has frame members separated by a distance substantially corresponding to the width of the catalyst plates to be mounted. The frame members are provided with a series of guide slots open on top for admission of the catalyst plates. On the bottom edges of the frame members, there are provided base supports for the bottom edges of the catalyst plates. The frame members themselves also form lateral supports for the catalyst plates to prevent movement thereof when mounted in the module. The mounting modules, once loaded with the planar elements, can be combined into a larger frame in a horizontal mode, or they can be vertically stacked, such as in the flue of a combustion furnace itself. The plates are typically pre-coated with a material that is catalytic to further the conversion of the gaseous compounds passing thereby.
