Distance between the heat exchange tube core and the furnace wall in boiler design
Thread Content
In boiler design, when arranging the heating surfaces, the distance between the center of the heat exchange tubes and the furnace wall should not be too large; otherwise, a flue gas corridor phenomenon will occur； It can’t be too small, as this will create dead zones and make installation difficult as well. What is the appropriate spacing for you?
For cylindrical tube furnaces, it is generally 1.5 times the outer diameter of the furnace tube.
