Thermo-mechanical life prediction for material lifetime improvement of an internal cooling system in a combustion liner

An approach for estimation of water wall degradation within pulverized-coal boilers

“…5. On this basis, appropriate averages can be obtained [14,23]. Modelling of these processes is very difficult and needs more information regarding the combustion process.…”

“…Using the approximate solutions (1) through (5) together with the algebraic closures (6) through (14), one can calculate the change of the temperature profile with time. In Fig.…”

“…Therefore, in the present paper, having at our disposal numerous operating behaviour data [7,14,39], we undertake a task of the numerical modelling of high-temperature creep and erosionecorrosion degradation of water walls (i.e., an evaporator tube pipe). Modelling our domestic conditions, we have used the steel 21HMF that corresponds to the 1% Cr steel 13CrMo-4-4 (T11) applied usually for furnace panels in the evaporators of supercritical boilers.…”

“…The best way to determine the actual root cause of ash corrosion or high-temperatures oxidation is by tube analysis and by evaluation of both the scale and deposits of the inside and outside diameters [14,15].…”

Effect of thermal stress on creep lifetime for a gas turbine combustion liner

“…Likewise, for the combustion systems, there are also numerous studies such as combustion mechanism, combustion gas flow, and heat transfer in combustors [13][14][15]. There have been some efforts to predict failure and lifetime in combustors, but only for the local part of component or segments in archival journal papers [16,17].…”
