Hot water recovery

This post was last edited by “Hasty Passerby” on May 16, 2018, at 15:23. Dear colleagues, due to our manufacturing processes, our company generates around 200 tons of hot water per hour. Previously, this water was simply discharged. Now, we’d like to recycle it—whether for steam generation or cooling purposes. Are there any cost-effective and safe solutions you could recommend? Or perhaps we can exchange ideas regarding energy-saving recycling methods.
It is recommended that the original poster provide the parameters for hot water, to facilitate discussion among users. Thank you!
Hot water can be used as a source of partial heat tracing and heating; it is advisable to list the temperature and water quality details to facilitate evaluation by everyone
It can be used to heat materials by heat exchange, to generate steam in boilers, as a heating element, or to supply hot water to refrigerators.
With such a large volume, it can be used for heat tracing or preheating of feed materials; it can also be used for steam generation. It depends mainly on what your system requires, and the overall process needs to be taken into consideration in order to select the option with the best cost-performance ratio
Heating and warm air systems are already in use; this amount cannot be utilized
The system requires cooling, but there is concern that leaks from the system could contaminate the water quality; it’s better to produce gas instead
If leakage is a concern, it’s better to generate steam, as this allows for maximum utilization of heat
200 tons per hour? This amount is significant; the previous heat exchange system was used to convert low-grade heat.
