The issues of record-keeping of the damages caused by the impact of high local gas temperatures and local temperature inhomogeneity and the reliable estimate of the remaining life of high temperature elements are topical and their solution will provide a reliable and long-term operation for power generating equipment. Using the data of numerous investigations of thermal state, stress-strain state and the remaining life of boiler pipelines we developed and substantiated the methods of calculated estimate of the effects of the local inhomogeneity of thermal flows on the damageability and remaining life of the elements to extend the operation life of power equipment. Based on the operation data of industrial power equipment and the data of physical experiments appropriate initial and boundary conditions were selected that enabled an adequate simulation of the influence of the irregular temperature fields of combustion products. Using the Solid Works bundled software we carried out computational investigations that take into account the gas dynamics of the behavior of gas flow streamlining the pipeline. Thermal and stress-strain states were defined and service life of the boiler unit pipeline was determined depending on equipment operation conditions. The obtained research data can be used for high and low power engineering, industry and gas transportation system of Ukraine and other fields of science and engineering to operate equipment elements at high temperatures and high local temperature gradients when the burners of a stabilizing type equipped with the gas temperature field shape control system are used.
