<p>The coating has layers (5-7) placed on an inner surface (3) with a layer thickness, where the layers are made of synthetic resin with glass fiber or synthetic fiber and particle reinforcements. A refractory layer having another layer thickness of 50-60 mm is arranged on the layers, where the refractory layer is formed by a refractory mass (8) based on fire clay or perlite. Expansion bolts (4) are fastened to the surface and protruded into a channel with a height. A thickness of the expansion bolts exceeds the former layer thickness and is smaller than a sum of the layer thicknesses. An independent claim is also included for a method for cleansing of an inner side of waste gas channels.</p> |
