In a D-type boiler, which tubes would be located in the generating tube bank?

Explanation:
In a D-type boiler, the generating tube bank is the section where water is heated toward steam and where the superheater is installed. The superheater assembly requires support tubes to hold its tubes in place within that same bank, so those support tubes are located in the generating tube bank. Waterwall tubes form the furnace walls, economizer tubes lie in the economizer section after combustion, and furnace tubes are inside the furnace area but not part of the generating bank. Therefore, the tubes that belong to the generating tube bank are the superheat support tubes.
