I don’t know why this is B. 【Classification of steam superheaters 1. Based on the heat transfer method, steam superheaters can be divided into convective, radiant, and semi-radiant types.】 2. Based on their structural characteristics, steam superheaters can be classified into coiled-tube type, screen type, wall-type, and encircled-wall type. They are all composed of several parallel tubes and inlet and outlet manifolds. 3. The location and structure of superheaters in boilers can be classified as follows: wall-type superheaters located on the furnace wall, partition screens and rear screens at various positions above the furnace, vertical and horizontal superheaters in the convective flue, and encircling superheaters that form the horizontal flue and the tail shaft flue. 】
The last paragraph on page P42 of the textbook states that a superheater involves convective heat transfer and radiative heat transfer
