How to configure the series connection of HTRI economizers

When setting the series configuration for the economizer in the HTRI software, ensure that the following steps are followed: 1. **Select the correct arrangement type**: When setting the arrangement, choose “Series arrangement” rather than “Parallel arrangement”. This is usually adjusted in the heat exchanger’s configuration or settings section. 2. **Verify fluid distribution**: Ensure that the fluids on the shell side and tube side are fed correctly. The shell side should be flue gas, and the tube side should be water. Check whether the inlet and outlet positions of the fluid meet the requirements for series connection. 3. **Adjusting the number of channels**: Series connection usually means that the fluid flows through multiple channels in sequence. It may be necessary to increase the number of channels on the shell side or tube side to achieve series flow. 4. **Use partitioning tools**: If the software supports it, you can try using partitioning tools (such as Zone division) to divide the heat exchanger into several operational zones, with each zone representing a sequential part of a process. 5. **View help documents and examples**: Refer to the help documents or examples provided by HTRI, as these usually offer specific guidance on how to configure particular processes.
