While the heating liquid sprinkled by the trough is flowing down along the outer surfaces of the plurality of heat transfer tubes, the liquefied gas flowing through the plurality of heat transfer tubes does heat exchange with the heating liquid on the outer surfaces of the plurality of heat transfer tubes. Owing to the heat exchange with the heating liquid, the liquefied gas vaporizes.

  • the vaporizing apparatus described in connection with the various embodiments mainly has the following features.
  • a vaporizing apparatus is configured to vaporize liquefied gas by way of heat exchange between the liquefied gas and heating liquid having a higher temperature than the liquefied gas.
  • the vaporizing apparatus includes a heat transfer panel including a plurality of heat transfer tubes standing and horizontally lining up for guiding the liquefied gas; a trough lying at a position lower than an upper end of the heat transfer panel for supplying the heating liquid to an outer surface of each of the plurality of heat transfer tubes; and a manifold arranged on one end side of the trough in a lining-up direction of the plurality of heat transfer tubes for supplying the heating liquid into the trough.
  • the trough includes a bottom wall extending in the lining-up direction of the plurality of heat transfer tubes, a first end wall extending upward from one end of the bottom wall, the one end being closer to the manifold in the lining-up direction, and a second end wall extending upward from the other end of the bottom wall, and away from the first end wall in the lining-up direction.
  • the first end wall having an inflow port for allowing the heating liquid to flow in.
  • the manifold for supplying the heating liquid into the trough is arranged on the first end wall side of the trough, and the first end wall has the inflow port. Therefore, the flow path of the heating liquid from the manifold to the trough is shortened. In other words, the flow path of the heating liquid from the manifold to the trough is not required to reach an inflow port formed in a bottom wall beyond the first end wall, unlike a structure in which heating liquid flows from a manifold into a trough through an inflow port formed in the bottom wall.
  • the vaporizing apparatus may further include a rise suppressing portion configured to suppress a liquid surface rising of the heating liquid due to a collision of the heating liquid having flowed in the trough against the second end wall.
  • the heating liquid having flowed in through the inflow port flows toward the second end wall, and collides against the second end wall.
  • a part of the heating liquid having collided against the second end wall flows upward at a location closer to the second end wall, and causes the liquid surface of the heating liquid to rise.
  • the rise suppressing portion suppresses the liquid surface rising, and thus prevents an excessive supply of the heating liquid to the outer surfaces of heat transfer tubes closer to the second end wall. Accordingly, this configuration keeps the heat exchange from varying among the plurality of heat transfer tubes.
  • the rise suppressing portion may include a lid member lying at a position higher than the inflow port between the first end wall and the second end wall and extending in the trough in the lining-up direction.
  • the lid member may lie at a location closer to the first end wall, a location closer to the second end wall, or an intermediate location between the first end wall and the second end wall.
  • the lid member suppresses a liquid surface rising near the inflow port when disposed at a location closer to the first end wall.
  • the lid member suppresses the liquid surface rising attributed to the collision of the heating liquid against the second wall when disposed at a location closer to the second end wall.
  • the lid member suppresses the liquid surface rising at an intermediate location between the first end wall and the second end wall when disposed at the intermediate location.
  • the lid member may include a plate entirely extending in the lining-up direction from the first end wall to the second end wall, or a plurality of plates lying between the first end wall and second end wall and spaced away from one another in the lining-up direction.
  • the lid member including the plate entirely extending in the lining-up direction from the first end wall to the second end wall suppresses a liquid surface waving or rising over the entire length of the trough.
  • the lid member including the plurality of plates lying between the first end wall and the second end wall and spaced away from one another in the lining-up direction suppresses a liquid surface rising of the heating liquid over a wide range of the trough in the longitudinal direction thereof without any excessive increase in the weight of the trough.
  • the lid member may have a through hole vertically passing through the lid member.
  • a part of the heating liquid flowing upward can flow into a space above the lid member through the through hole of the lid member.
  • a resistance occurs in the heating liquid when the heating liquid passes through the through hole.
  • the liquid surface rising of the heating liquid is suppressed at a location closer to the second end wall.
  • the rise suppressing portion may include an obstructor provided between the first end wall and the second end wall.
  • the obstructor may allow the heating liquid having flowed in the trough through the inflow port to collide against the obstructor before the collision against the second end wall to thereby reduce a collisional force of the heating liquid against the second end wall.
  • the heating liquid having flowed in through the inflow port collides against the obstructor before the collision against the second end wall.
  • the flow rate of the heating liquid is reduced by the obstructor before the collision against the second end wall. Consequently, when the heating liquid collides against the second end wall, a decreased collisional force generates, which makes it unlikely to cause a heating liquid flow having greater upward velocity components. In other words, the liquid surface rising is suppressed at a location closer to the second end wall.
  • the obstructor may stand upright or tilt with respect to the bottom wall of the trough.
  • the obstructor when being kept standing upright with respect to the bottom wall of the trough, the obstructor effectively decreases the intensity of the heating liquid by allowing the heating liquid to collide against the obstructor.
  • the obstructor when being kept tilting with respect to the bottom wall of the trough, the obstructor can decreases the intensity of the heating liquid and change the flowing direction of the heating liquid.
  • the obstructor may be spaced away from the bottom wall of the trough.
  • a part of the heating liquid can flow downstream through a gap between the obstructor and the bottom wall of the trough. Since the gap is away from the liquid surface of the heating liquid, the liquid surface avoids excessively rising even due to the flow of the heating liquid passing through the gap. Further, the heating liquid can flow toward the second end wall by passing through the gap. Thus, no excessive decrease in the flow occurs at a location closer to the second end wall.
  • the obstructor may include a plurality of obstructive pieces separating from each other.
  • the obstructor including the plurality of obstructive pieces separating from each other can provide in the trough a plurality of regions at which the heating liquid collides against the obstructive pieces.
  • the resistance in the heating liquid is higher.
  • the resistance in the heating liquid is lower.
  • the obstructer may have a through hole passing through the obstructor in the lining-up direction.
  • the through hole passing through the obstructor is formed in the lining-up direction of the plurality of the heat transfer tubes. Therefore, a part of the heating liquid having flowed through the inflow port formed in the first end wall can flow from an upstream region to a downstream region of the obstructor through the through hole. A higher resistance occurs in the heating liquid when the heating liquid passes through the through hole, thus reducing the flow pressure of the heating liquid from the first end wall toward the second end wall. As a result, the liquid surface rising of the heating liquid is suppressed at a location closer to the second end wall.
  • the vaporizing apparatus may include a closing member provided in the trough for closing a part of the inflow port.
  • the closing member is removable from the trough.
  • the closing member can regulate an inflow of the heating liquid into the trough by closing a part of the inflow port and thus applying the resistance to the heating liquid at the inflow port of the trough. Moreover, the closing member is removable from the trough. Accordingly, this configuration makes it possible to lower the resistance in the heating liquid passing through the inflow port by removing the closing member.
  • the vaporizing apparatus may include: another heat transfer panel including a plurality of heat transfer tubes and disposed away from the heat transfer panel; another trough for supplying the heating liquid to an outer surface of each of the plurality of heat transfer tubes of the another heat transfer panel; and a plurality of supplying pipes respectively connected to the trough and the another trough for supplying the heating liquid from the manifold to the trough and the another trough.
  • One of the heat transfer panel and the another heat transfer panel is adapted for the heat exchange between the liquefied gas and the heating liquid having a flow rate smaller than a flow rate of the heating liquid of the other of the heat transfer panel and the another heat transfer panel.
  • the supplying pipe connected to the trough of the one heat transfer panel has a smaller flow path cross-sectional area than the supplying pipe connected to the trough of the other heat transfer panel.
  • the troughs receive the heating liquid through the plurality of supplying pipes connected with the manifold.
  • the supply amounts of the heating liquid to the troughs differ from each other depending on the flow path cross-sectional area of the corresponding supplying pipe.
  • the supplying pipe connected to the trough configured to supply the heating liquid to the heat transfer panel which requires the heating liquid having a relatively small flow for the heat exchange between the heating liquid and the liquefied gas has a relatively small flow path cross-sectional area. In this way, the supplying pipe avoids supplying too much amount of the heating liquid to the trough.
  • the vaporizing apparatus may further include: at least two heat transfer panels including the heat transfer panel, and disposed away from each other; three troughs including the trough; and a plurality of supplying pipes respectively connected to the three troughs for supplying the heating liquid from the manifold to the three troughs.
  • Specified two troughs among the at least three troughs lie in outermost positions of a row of the at least two heat transfer panels in such a way that each of the specified two troughs in the outermost positions is adjacent to one of the at least two heat transfer panels, a remaining trough is placed between the heat transfer panels adjacent to each other.
  • a pair of the supplying pipes connected to the specified two troughs have a smaller flow path cross-sectional area than the supplying pipe connected to the remaining trough.
  • each of the two outermost troughs is adjacent to one of the heat transfer panels, and the remaining trough is adjacent to two of the heat transfer panels.
  • the outermost two troughs allow the heating liquid to flow downward to the one heat transfer panel.
  • the remaining trough allows the heating liquid to flow downward to the two heat transfer panels. Since the supplying pipes connected with the two outermost troughs have the smaller flow path cross-sectional area than the supplying pipe for the remaining trough, the supply amount of the heating liquid to the two outermost trough is relatively small. Further, the troughs receive the heating liquid through the plurality of supplying pipes connected with the manifold.
  • the supply amounts of the heating liquid to the troughs differ from each other depending on the flow path cross-sectional area of the corresponding supplying pipe. In this way, a suitable flow is obtainable for the number of heat transfer panels to which the heating liquid is supplied.
  • This configuration eliminates the necessity of attaching any fluidic device, such as a valve, for reducing the supply amount of the heating liquid to the supplying pipes for the two outermost troughs.
  • the vaporizing apparatus may further include another lid member lying at a position vertically away from the lid member.
  • At least one of the lid member and the another lid member may entirely extend in the trough.
  • the vaporizing apparatus may further include a vertical lid disposed between the lid member and the another lid member.
  • the rise suppressing portion may include an obstructor between the first end wall and the second end wall.
  • the obstructor may be in contact with a bottom surface of the lid member.
  • the obstructor may suppress a collisional force of the heating liquid against the second end wall by allowing the heating liquid having flowed in the trough through the inflow port to collide against the obstructor before the collision against the second wall.
  • the obstructor may have a through hole passing through the obstructor in the lining-up direction.
  • the obstructor is attachable to the lid member by a contact with the bottom surface of the lid member.
  • the obstructor having the through hole allows the heating liquid to flow toward the second end wall through the through hole. This configuration thus avoids excessive lowering of the surface level of the heating liquid at a location closer to the second end wall.
