    Abstract: A heat recovery steam generator that includes a first steam drum (118a) for receiving a flow of water and steam from an evaporator. The first steam drum is adapted to provide the flow of water and steam to a second steam drum. The second steam drum (118b) is in fluid communication with the first steam drum and receives the flow of water and steam from the first steam drum and separates steam from the flow of water and steam to form a separated steam. There is a steam flow outlet (156) positioned in the second steam drum, the steam flow outlet adapted to release the separated steam from the second steam drum.

    Abstract: A method of controlling stress in a boiler pressure vessel comprises limiting the diameter of a drum (10) of the boiler pressure vessel and preheating at least a portion of the wall (12) of the drum (10). Limiting the diameter of the drum (10) allows pressure in the drum (10) to be increased for a given mechanical stress. Furthermore, preheating the wall (12) of the drum (10) reduces peak thermally induced stresses in a material from which the drum (10) is fabricated.

    Abstract translation: 控制锅炉压力容器中的应力的方法包括限制锅炉压力容器的鼓（10）的直径并预热至所述滚筒（10）的壁（12）的至少一部分。 限制鼓（10）的直径允许鼓（10）中的压力在给定的机械应力下增加。 此外，预热滚筒（10）的壁（12）减少制造滚筒（10）的材料中的热诱导应力峰值。
