Boiler bed material is a key component used in fluidized bed combustion (FBC) boilers, which are employed in thermal power plants. It typically consists of granular materials like sand or ash. These particles create a "fluidized bed" when air is blown through them, allowing for efficient mixing of fuel, air, and heat. This enhances combustion efficiency and reduces emissions. The bed material also retains heat, ensuring better temperature control during combustion. It is chosen for its thermal stability, resistance to abrasion, and ability to withstand high temperatures.
ire bricks, also known as refractory bricks, are specially designed bricks made to withstand extremely high temperatures. They are primarily used in high-heat environments like fireplaces, furnaces, kilns, and pizza ovens. These bricks are made from fire clay, alumina, and silica, which give them heat-resistant properties. Fire bricks can retain heat, resist thermal shock, and prevent structural damage from the intense heat. They come in different shapes and sizes, tailored for specific uses, and help improve energy efficiency in high-temperature applications.
Fireclay powder is a heat-resistant material made from finely ground fireclay, a type of clay that can withstand high temperatures. It is commonly used in the construction of furnaces, kilns, fireplaces, and fire bricks due to its ability to endure extreme heat without cracking or breaking down. Fireclay powder is mixed with other materials like sand or cement to create fire-resistant linings and structures, making it a vital component in industries requiring thermal insulation and heat resistance.
"Castable" generally refers to materials, often refractory, that can be shaped or molded by casting into desired forms. Refractory castables are a type of heat-resistant material made of a mixture of cement, aggregates, and binders. These are used in high-temperature applications like furnaces, kilns, and boilers due to their ability to withstand extreme heat without breaking down or deforming.
High alumina castable is a type of refractory material made from high alumina cement and aggregates. It has excellent thermal resistance, high strength, and is designed to withstand extreme temperatures, making it ideal for applications in furnaces, kilns, and incinerators. Its composition typically includes more than 70% alumina, which provides durability and resistance to corrosion and wear. Additionally, it is easy to install by casting or gunning, and it can be used to create monolithic linings or repairs in high-temperature environments.
Mortar is a mixture used in construction to bind building materials like bricks, stones, and concrete blocks. It typically consists of cement, lime, sand, and water. Mortar helps fill gaps between bricks or stones, providing strength, stability, and protection against weather. There are different types of mortar, such as Portland cement mortar and lime mortar, each used for specific construction purposes. It hardens after being applied, forming a durable adhesive that supports the structure.
