Annealing is a heat treatment method that alters the microstructure of a material to alter its mechanical or electrical properties. Typically, in steels, annealing is employed to reduce hardness, increase plasticity and help eliminate internal stresses. Annealing may be a generic term and should refer to subcritical, intermediate or full annealing in a very type …

Typically, powder-drying operations involve the application of heat to a solution, wet powder or slurry. Bulking and packaging of the dried powder usually follows. Common dryer types include tray, fluidized bed, and spray, rotary and vacuum dryers. In any type of dryer, the dry powder can build up as a bulk or layer in various …
Wood drying (also seasoning lumber or wood seasoning) reduces the moisture content of wood before its use. When the drying is done in a kiln, the product is known as kiln-dried timber or lumber, whereas air drying is the more traditional method. There are two main reasons for drying wood: Woodworking: When wood is used …
A heat exchanger is a system used to transfer heat between two or more fluids. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power …
