Title:
ボイラーチューブ/熱交換器保護用耐火タイル張り構造
Document Type and Number:
Japanese Patent JP2004520561
Kind Code:
A
Abstract:
A refractory tile system (60) includes a barrier layer coating (61) applied to the wall (16) of a boiler. Refractory tiles (66) are then fastened to the tu be wall (16) utilizing a floating attachment mechanism (68) to provide a relatively high degree of freedom of movement relative to the tube wall to accommodate micro-scale bowing of the tile generated by the relatively large temperature gradient and mean temperature typically experienced by such tile s. Each tile (66) is also isolated from adjacent tiles by providing a predetermined gap (70) therebetween of sufficient size to effectively preven t macro-scale bowing. Moreover, a compressible fibrous mortar is disposed in t he gap between each adjacent tile to prevent contaminants from passing therethrough.
