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.
