Options for Improving the Efficiency of Heat Recovery

Calculate the unfired steam using 25 degree pinch and 20 degree approach points. Use a heat loss factor of 0.98. Solution: Assume 10 psi pressure drop in the superheater. The drum pressure is 610 psig and the saturation temperature is 492 F. The gas temperature leaving the evaporator=492+25=517 F.

Steam Heating System Operating Temperature

However a residential steam boiler pressure is so modest (0.2 psi to 0.5 psi) that the temperature increase above 212 °F will be no more than about 220 °F. A commercial boiler system heating a high-rise building may be operating at much higher pressures, perhaps 20 to 40 psi in order to be able to force steam to 20 or 40 floors of building

Operating temperature. It is important that the water in the feedtank is kept at a high enough temperature to minimise the content of dissolved oxygen and other gases. The correlation between the water temperature and its oxygen content in a feedtank can be seen in Figure 3.11.1. If a high proportion of make-up water is used, heating the

Oct 27, 2020 · Anders Celsius was the guy that dreamt up that one. It was a long time ago (1742) and he decided to make the boiling point of water zero degrees Celsius, and the freezing point of water 100 degrees Celsius. And he could do that because he was Anders Celsius and it was his scale. So there. No one uses Celsius these days.
