A process for installing a refractory burner block in a glass furnace crown, wherein the glass furnace crown comprises a second refractory material different than the burner block refractory, includes installing a refractory crown block in the furnace crown, wherein the crown block refractory is compatible with the burner block refractory and the second refractory material, wherein the crown block is provided with a hole for accepting the burner block; and disposing the burner block into the crown block hole in sealing engagement therewith. A process for installing a refractory burner block in a hot glass furnace crown, wherein the glass furnace crown comprises a second refractory material different than the burner block refractory, includes removing crown insulation from the exterior of the furnace crown; inserting a patch of refractory material compatible with the furnace crown second refractory material into the crown in the vicinity of the removed insulation; drilling a hole into the crown through the refractory patch, optionally with a water cooled diamond drill; and, inserting the refractory burner block into the hole in the furnace crown through the refractory patch. A process for installing a refractory burner block in a glass furnace crown, wherein the glass furnace crown comprises a highly thermally conductive fused cast refractory material, includes installing an insulating barrier mounting block on the upper surface of the furnace crown, wherein the mounting block is compatible with the burner block refractory and the fused cast refractory material, wherein the mounting block is provided with a hole for accepting the burner block, and wherein the insulating barrier mounting block is prepared when the furnace crown is not hot; and disposing the burner block into the mounting block hole in sealing engagement therewith.
