In this article, an analysis of damageability and determination of dominating mechanisms through which thinning occurs to the metal of elements used in the tube system of heat recovery boilers used as part of combined-cycle plants during operation and during their outages is presented.Abstract:
We present the results from an analysis of damageability and determination of dominating mechanisms through which thinning occurs to the metal of elements used in the tube system of heat recovery boilers used as part of combined-cycle plants during operation and during their outages. Results obtained from putting in use a technology for making the tubes of such boilers more resistant to erosion-corrosion wear with the aid of film-forming amines are also presented. Measures are proposed on extending the service life of the tube system of heat recovery boilers used as part of combined-cycle plants and operating under the conditions of single- and two-phase flows.read more
