Rules Governing Temperature Variations of Water Walls with Rifled Tubes in Once Through Boilers during Gliding Pressure Operation |
| |
| Abstract: | The paper reports on test results of wall temperature characteristics, of quadri rifled vertical riser tubes in the pressure range of 13.0～27.0MPa, obtained on domestic manufactured 600MW super critical boilers during gliding pressure operation. The rules that govern tube wall temperature variations with changing pressure, mass flow, heat load and medium enthalpy were studied and reliable data have been provided for the design of super critical pressure boilers intended for gliding pressure operation.
