FIGURE 5-19. Throat tile and furnace liner installation notes 83” boilers
Notes:
1) No insulation, cut bricks, or cut tiles to be installed in upper 120° section of the furnace.
2) Pack all bricks and tiles tightly with a mallet and remove excess mortar. Typical mortar joint
shall be approximately 1/16".
3) Do not apply mortar between insulation and bricks, tiles, or furnace.
4) Do not cover furnace weld seams with insulation. Cut a strip of insulation out to expose weld.
5) Du
ring installation, support upper tiles with wooden supports in a diagonal fashion until row is
complete.
6) To insure a tight fit and maximum I.D. of arch bricks, place a 3" square scrap piece of insulation
as a shim between bricking tool collar and I.D. of upper half of arch bricks (as necessary).
7) Stagger mortar joints on each row of liner tiles.
8) Fill the first two full corrugations under the liner
tiles with
Vee-Block mix refractory up to the horizontal centerline (3 o-clock to 9 o-clock position).
Do not fill the first half corrugation (30 PPM only).
