Furnace brick layout design

Generally speaking, compressible refractory fibers are available both vertically and horizontally to serve as a buffering layer; the horizontal refractory fibers have a thickness of around 20 mm between the insulation bricks and the furnace walls of the gasifier, while the vertical compressible fibers have a thickness ranging from 50 mm to 75 mm at the vault area. When constructing the additional three layers of refractory bricks, polyvinyl chloride plastic films are used as separators; during heating, these plastic films burn away, and the space thus created eliminates the forces acting between each layer of refractory bricks. At the point where the vault meets the cylindrical wall, there is also an expansion joint that serves as a buffer; there is an expansion joint of 3 to 5 mm between the bricks at the base of the cone and the cylindrical wall, and there are expansion joints of 2 to 3 mm between each layer of bricks at the base of the cone.
