Purbolaksono J. 26024539700 57188728682 6602271377 8621252500 Boilers; Coal; Fossil fuel power plants; High temperature operations; Steam; Steam power plants; Thermoelectric power plants; Tubes (components); Alloy 617; Condition; Creep damages; Creep life; High-temperature operation; Steam pressures; Steam temperature; Supercritical; Thermal-power plants; Ultra-supercritical power plants; Creep The 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 Ltd Final 2023-05-29T09:05:24Z 2023-05-29T09:05:24Z 2021 Article 10.1016/j.engfailanal.2021.105746 2-s2.0-85115296266 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85115296266&doi=10.1016%2fj.engfailanal.2021.105746&partnerID=40&md5=87bd887e807e5bed97b12c473eb4e523 https://irepository.uniten.edu.my/handle/123456789/25880 130 105746 Elsevier Ltd Scopus |
