PHE-based hot water system
Process hot water raised indirectly from plant steam, with the duty set by flow, required delivery temperature and the available steam pressure.
The application
A process needing a steady hot water supply at a controlled temperature, where the water cannot be allowed steam contact and the draw-off is intermittent rather than constant.
What was engineered
A packaged system built around a plate heat exchanger, with storage and recirculation sized to the draw-off pattern, a steam control valve, RTD sensing and panel-based control, delivered as a single skid with piping, valves and instrumentation in place.
Result on the plant
Delivery temperature held across the load range instead of drifting with demand, and the steam side sized to the real duty rather than to a rule of thumb. Measured duty and heat-load data for this configuration are available on request.
