PURPOSE:To improve the performance and facilitate the cleaning work by providing a detachable buffle plate in a hot water inlet that is much smaller than the container and a tapered nozzle tip having a plug for cleaning so that an even amount of flow is distributed among respective heat transmission pipes and a uniform water film may be formed. CONSTITUTION:Hot water 7 flows from the bottom through a secondary pipe 5 and a pump 6 to hit a buffle plate 10 in the upper part of the vaporizer shell 1, and then enters into the vaporizer shell 1. The hot water flows into heat transmission pipes 3 from the opening 11a. By equalizing the submerging level of nozzle tips 11, and by preventing leaving on the attaching surface due to the tolerance of the inner diameter of the heat transmission pipes 3, the inflow to the heat transmission pipes 3 is made uniform. By providing a small diameter buffle plate 10 and a cleaning plug 12, the cleaning inside the pipe plate 2 and heat transmission pipes 3 is facilitated. |
