Refractories are non – metallic materials that are suitable for the construction or lining of furnaces operated at high temperatures [1]. These are used to line kilns, incinerators and reactors and also . The failure of fire‐brick in oil fired furnaces results from (1) spalling and falling of side wall bricks, (2) disintegration of bricks in direct path of flame, (3) glazing of surface with green glaze which penetrates and weakens brick, and (4) erosion by flame. A plea is made for more research in the field. Overview of Refractory Materials A. Bhatia, B.E. COURSE CONTENT Abstract Refractories are heat resistant materials used in almost all processes involving high temperatures and/or corrosive environment. These are typically used to insulate and protect industrial furnaces and vessels due to their excellent resistance to heat, chemical attack and. Armil CFS is a custom manufacturer of high temperature process equipment, including reheat furnaces. Armil CFS alsodistributes and installs a wide range of ceramic fiber and silica fiber refractories. Armil CFS also stocks insulating firebrick, back up insulation. microporous silica, etc.

  A furnace is an equipment used to melt metals for casting or to heat materials to change their shape (e.g. rolling, forging) or properties (heat treatment). Since flue gases from the fuel comein direct contact with the materials, the type of fuel chosen is important. For example, some materials will not tolerate sulphur in the fuel. Solid fuels generate particulate matter, which will interfere.

Mineral wool is any fibrous material formed by spinning or drawing molten mineral or rock materials such as slag and ceramics. Applications of mineral wool include thermal insulation (as both structural insulation and pipe insulation, though it is not as fire-resistant as high-temperature insulation wool), filtration, soundproofing, and hydroponic growth medium.

Written in a student-friendly manner, the book begins with the introduction to fuels, furnaces and refractories. It further exposes the reader to the different types of fuels with their testing methods.
