What is Supercritical Steam? Technology-Articles.com
What is supercritical steam? While a supercritical fluid is any substance at a temperature and pressure above its critical point, where distinct liquid and gas phases do not exist. So, supercritical steam is water at a temperature and pressure above its critical point (>647.096 K, >22.064 MPa), where distinct liquid water and steam phases do…

A small supercritical once-through steam generator (OTSG) includes a radiant section with a furnace coil, and a convection section downstream of the radiant section that includes a superheater which is fluidically connected to the furnace coil. Optionally, the OTSG is devoid of a steam separator. An economizer can also be included downstream of the superheater.

Tube Failures in High Pressure Boilers - Bright Hub
2020-5-27 · There are twenty-two primary reasons for tube failures in a boiler, which can be classified under six major groups. They can be analyzed and corrective and preventive action can taken. Good operating and maintenance practice reduces tube failures. Tube failures during the initial operation period, the normal operation period, and after ten to fifteen years operation show different trends.
