A radiant tube is a type of heat exchanger used in fired heaters and other industrial heating systems. It consists of a long, hollow tube made of metal that is heated by combustion gases or electric heating elements. The tube radiates heat outward, heating the surrounding air or fluid passing through it. Radiant tubes are often used in high-temperature applications where direct contact between the heating source and the material being heated is not desirable. They are commonly used in furnaces, ovens, and other industrial heating equipment.
A convection tube is a type of heat exchanger that utilizes the principle of convection to transfer heat from one fluid to another. Convection is the process of heat transfer through the movement of fluid, either liquid or gas. In a convection tube, one fluid flows through the tube while another fluid flows around the outside of the tube. As the inner fluid is heated or cooled, it transfers heat to the outer fluid through convection.
Convection tubes are commonly used in boilers, heat exchangers, and other industrial heating and cooling systems. They are designed to efficiently transfer heat between two fluids while minimizing energy loss. Convection tubes can be made of various materials, such as metal or ceramic, depending on the specific application and temperature requirements.
