The temperature field calculation of water wall of supercritical and ultra-supercritical boilers, especially those located at the burner region, is of significant importance for boiler safe operation.
A supercritical steam generator is a type of boiler that operates at supercritical pressure, frequently used in the production of electric power. In contrast to a subcritical boiler in which bubbles can form, a supercritical steam generator operates at pressures above the critical pressure – 3,200 psi or 22 MPa.
2014-3-4 · PERFORMANCE ANALYSIS OF SUPERCRITICAL BOILER In this case, a drum-type boiler is used because the steam needs to be separated from water in the drum of the boiler before it is superheated and led into the turbine. Above an INTERNATIONAL JOURNAL OF MECHANICAL ENGINEERING AND
2017-5-9 · considered, a tower boiler has the greatest length of the steam piping, and the horizontal boiler has the lowest one. The main drawback of the latter layout is a significant complication of the ash and slag removal due to the fact that the bottom wall of the boiler gas duct must have a slope of 50-60° to efficiently remove ash.
This means, that there is a non-homogeneous mixture of water and steam in the evaporator part of the boiler. In this case a drum-type boiler is used because the steam needs to be separated from
