Steam Temperature Imbalance in Tangential Fired Boilers

Nov 05, 2009 · Steam Temperature Imbalance in Tangential Fired Boilers. In a tangential fired boiler, coal as a fuel can cause a considerable imbalance in the reheat steam temperature on the left hand and right hand sides. It is always misunderstood by many that this kind of difference is mainly due to design and needs to be corrected, even when the steam

Steam Inlet Temperature - an overview | ScienceDirect Topics

3.8 Material issues in the development of advanced steam plants. To attain a net efficiency of 50% a typical steam plant in northern Europe would require an inlet steam temperature in the 700–720 °C range at a steam pressure of 350 bar. In the USA because cooling water temperatures are high, steam conditions are even harsher at 760 °C/350 bar.

To generate steam, you have to reach at least 100C, or 212 degrees Fahrenheit. However, the more pressure that exists in the boiler, the higher the temperature can be. So you could have a boiler with a water temp of 450 degrees F. Someone who knows more about steam than I do can tell you what pressure it would be at in this condition.
