Boiler pipes include heat-exchanging tubes (tubes such as superheaters, reheaters, water wall tubes, economizers, etc.) and steam pipes (main steam pipes, reheated steam pipes, steam conduits, headers, connection pipes, etc.).
Water wall, superheater, reheater, economizer, air preheater
#Water wall, superheater, reheater, economizer, air preheater. The heated surface refers to the metal surface area of components such as steam boilers and additional heated surfaces that are in contact with flue gas; in other words, it is the surface area where heat exchange occurs between flue gas and water (or steam). It is denoted by H, and its unit is m2. In engineering, the size of the heated surface is generally determined based on the side where flue gas releases heat. #
The heated surface tubes include tubes in the superheater, reheater, water wall, economizer, etc； Steam pipes include main steam pipes, reheat steam pipes, steam conduits, headers, connection pipes, and other such pipes.
Water wall tubes, convection tube bundle tubes, flame tubes
