    • The present document describes a boiler for heating a cold fluid with a hot fluid. The boiler comprises a lower drum, an upper drum, a plurality of right tubes for conveying the cold fluid, where each of the right tubes are fluidly connecting the lower drum and the upper drum, where the right tubes form a right wall and where each of the right tubes comprises at least one left inwardly extending portion extending toward a left wall and a plurality of left tubes for conveying the cold fluid, where each of the left tubes fluidly connect the lower drum and the upper drum, and where the left tubes form the left wall facing the right wall, where each of the left tubes comprises at least one right inwardly extending portion, each extending toward the right wall.

    • A heat exchange assembly for generating steam from a second medium to be used to drive a steam turbine for generating electricity or for other process, includes a tube having a longitudinal axis and an inner wall and an outer wall. The outer wall includes a plurality of spaced fins oriented generally perpendicular to the longitudinal axis. The inner wall defines a preheat zone and a dual phase zone. The preheat zone defines a helical rib configured to provide swirling motion and increase heat transfer surface area to liquid entering the tube increasing heat transfer from the tube to the liquid. The dual phase zone is spaced from the preheat zone and defines a helical rib configured to provide swirling motion to steam and liquid passing through the dual phase zone increasing heat transfer from the tube to the steam and liquid while preventing vapor stagnation and film boiling.
    • 用于从用于驱动用于发电或用于其它过程的蒸汽涡轮机的第二介质产生蒸汽的热交换组件包括具有纵向轴线,内壁和外壁的管。 外壁包括大致垂直于纵向轴线定向的多个隔开的翅片。 内壁限定了预热区和双相区。 预热区限定了螺旋肋,其构造成提供旋转运动,并且增加了进入管的液体的传热表面积,从而增加了从管到液体的热传递。 双相区域与预热区间隔开,并且限定了一个螺旋肋,该螺旋肋被构造成对通过双相区域的蒸汽和液体提供旋转运动,从而增加从管道到蒸汽和液体的热传递,同时防止蒸气停滞和膜沸腾。
