Shell and tube heat exchangers are widely used in chemical, pharmaceutical, and refining industries to transfer heat between two fluids with a temperature differential. Our company has developed a horizontal reboiler, also known as a kettle evaporator, with an optimized design to increase heat transfer efficiency. This innovation helps save on factory investment and improves energy utilization. The shell side of the unit features a large evaporation area in its upper section. Fluid on the shell side vaporizes, enters this larger space, and exits through the upper outlet pipe.
Building on standard reboiler designs, we can optimize several key details to enhance heat transfer efficiency while reducing manufacturing and operating costs. This is achieved by increasing the heat transfer film coefficient on one side of the equipment’s internal heat transfer position, increasing the number of tube passes, and achieving an optimal length-to-diameter ratio. Additionally, the reboiler's bottom has a unique sinking structure that maximizes the utilization of internal equipment space and minimizes leftover liquid after evaporation.
