SYSTEM FOR PRODUCING HIGH PRESSURE STEAM FROM LOW QUALITY WATER

摘要

The present disclosure relates to a system for producing high pressure steam from low quality feedwater for a designated process. The system includes a first closed loop in fluid communication with a boiler and a heat exchanger assembly. A first fluid flows through the first closed loop, and is of acceptable quality for use in a boiler. Heat from the boiler is transferred to a second loop through the heat exchanger assembly. The second loop includes the low quality feedwater, which is converted to high pressure steam. The high pressure steam produced from the low quality water can be used in the designated process. This reduces corrosion/downtime in the boiler that might otherwise occur if the low quality water was directly heated by the boiler.

主权项

1. A system for producing high-pressure steam from low quality feedwater, comprising:
a first closed loop containing a first fluid, the first closed loop containing a boiler and a heat exchanger assembly downstream of the boiler, wherein at least a portion of the first fluid exits the boiler as a high-temperature steam having a boiler output temperature; and a second loop in fluid communication with the heat exchanger assembly, the second loop containing the low quality feedwater; wherein the heat exchanger assembly is adapted to receive the first fluid from the boiler and transfer heat from the first fluid to the low quality feedwater in the second loop so that the low quality feedwater exits the heat exchanger assembly as a high-pressure steam and the first fluid exits the heat exchanger assembly as a condensed steam having a heat exchanger discharge temperature.
