dc.description.abstractThe efficiency of the coal-fired boilers can be enhanced through increasing the operating steam pressure and temperature. Though, higher steam pressure and temperature may potentially lead to increased boiler tube failure. In this work, a simple and practical procedure is proposed to estimate the remnant creep life of Alloy 617 for superheater and reheater tubing of ultra-supercritical (USC) boilers operating at a 700 �C or higher/35 MPa steam condition. Based on the estimations demonstrated here, operating 750 �C or higher with 35 MPa steam conditions for Alloy 617 required further viability studies and careful consideration, especially with regard to the increased rates of creep strength degradation. The use of Alloy 617 with considerably suitable tube geometries at 700 �C/up to 35 MPa steam conditions seemed to be allowable in service. A combination of the tube geometry and steam condition for the use in USC thermal power plants shall be carefully considered for reliable and continued services. � 2021 Elsevier Ltden_US
