PART II: INSTALLATION

Refractory Tile
It is necessary that the tile be installed properly. There must be adequate room for expansion and the tile must not bear the weight of
the boiler front wall refractory. It is also important that the tile not extend into the furnace area past the inner face of the boiler front
refractory over 50 mm. Installation drawing below provides instructions for installing the tile segments. Important points to be conside-
red during installation are:

it is advisable to purchase the tile retainer ring with the burner tile. This ring should be continuously welded into place on the out-
side of the tile ring. The ring must be properly centered before welding.

before the tile is installed, it is necessary to be sure no boiler frontwall refractory weight will be supported by the tile. It is advisable
to install a refractory arch of either arch or circle brick or plastic refractory to an inside finished diameter noted on the installation
drawing as “Furnace opening I.D. This provides a good solid background for the tile and removes the boiler frontwall refractory
weight from the tile.

the space between the burner tile and the refractory throat should be filled with a plastic refractory or castable on the bottom half of
the throat to pick up the weight of the tile and should be filled with high temperature insulation on the top half to allow for tile and
frontwall refractory expansion. A good bonding mortar of high temperature and low shrink should be used to bond the tile together.
