摘要:
Implementations described herein disclose epitaxial deposition chambers and components thereof. In one implementation, a chamber can include a substrate support positioned in a processing region, a radiant energy assembly comprising a plurality of radiant energy sources, a liner assembly having an upper liner and a lower liner, and a dome assembly positioned between the substrate support and the radiant energy assembly. The epitaxial deposition chambers described herein allow for processing of larger substrates, while maintaining throughput, reducing costs and providing a reliably uniform deposition product.

A hot blast stove dome comprises a first dome portion adapted for support on a combustion chamber wall of a hot blast stove, and a second dome portion adapted for support on a checker chamber wall of a hot blast stove, wherein a vertical expansion joint is provided between the first dome portion and the second dome portion and is adapted to allow the first dome portion and the second dome portion to independently accommodate vertical expansion of their respective supporting walls. The dome is suitably provided in a hot blast stove which comprises a combustion chamber, a checker chamber, a cylindrical housing comprising a combustion chamber wall and a checker chamber wall.

Thermal insulation for crowns and other industrial furnace parts having a surface subject to insulation. A reinforcing lattice made up of sectors is formed on such surface, such sectors are filled by refractory material. An adhesive protection layer made of material which is hardenable under the affect of the heat radiated from the furnace is then applied over the sectors of the refractory insulation material.

A furnace crown structure for furnaces used to fire ceramic materials at high temperature, which comprises silicon carbide beams.Each beam is laid crosswise to the longitudinal axis of the furnace, parallel to one another at constant pitch distances apart. The spaces between the beams one closed with satisfactory material plates.The furnace affords the possibility of forming a furnace crown from a light weight material which can provide for a rapidly achieved steady state operation and cooling down of the furnace.The furnace can reach temperatures in the 1600.degree. C. range.
