Expansion joints furnaces

Furnace linings, refractory blocks , gaskets, expansion joints, very high-temperature work. 

Use High-temperature insulation of kilns and furnaces, packing expansion joints, heating elements, burner blocks rolls for roller hearth furnaces and piping fine filtration insulating electrical wire and motors insulating jet motors sound deadening. 

Use Furnace curtains, stress-relief blankets, expansion joints, insulations involving encapsulation of refractory wools, aerospace composites, seals, and gaskets. 

Assembly drawings of furnace - with details of expansion joints and types of... 

Bridge walls of brick running down the center of the furnace may be used to achieve better control of the heat distribution inside the unit as seen in Figure 4. Care must be taken during shutdowns to clean out and repack the expansion joints to accommodate the thermal expansion that will occur when the furnace is brought on-line. Figure 5 shows the effect of inadequate expansion allowance in a division wall. It is imperative that all the expansion joints be fully functional to avoid buckling of the wall. 

Other examples of cylindrical lined vessels include blast furnaces, blast furnace stoves, basic oxygen furnaces, torpedo ladles, shaft kilns, multiple hearth furnaces, and rotary kilns. Some refractory lined vessels have refractory lined conical bottoms. When heated, the conical lining will want to displace upward. Therefore, the top mortar joint of the conical lining is critical. The cylindrical lining will be critical in restraining the upward expansion of the conical lining. At the ends of rotary kilns, restraint must be provided to contain and keep the kiln lining within the kiln shell.
