Kettle Reboiler - an overview | ScienceDirect Topics

The bottom column outlet stream is expanded in VLV valve to decrease its temperature and allow heat exchange with the top stream in the heat exchanger. When top column pressure is 21.6 bar, the temperatures and pressures of this stream is decreased from 131.5 to 29.3°C and the pressure is decreased from 22.6 to 1.5 bar.

Controlling TDS in the Boiler Water | Spirax Sarco

Using the figures from Example 3.12.5, if the boiler had been operating at 10 bar g, steaming at 5 000 kg/h and had a feedwater temperature of 80°C (hf = 335 kJ/kg), the change in energy requirement could be calculated as follows: Condition 1, manual TDS control: Blowdown rate = 11.1%. Example 3.12.7. Condition 2, automatic TDS control
