Abstract

Abstract: The structure characteristics of waste heat boiler exchange module in S109FA gas turbine combined cycle units were introduced. Based on the mechanism of damage, design of pipe bundle, influence of operation conditions, quality of welding, the damage reasons of the middle header outlet tube in the left of the high-pressure superheater 2 were analyzed. The purpose of protecting the pipe bundle from leakage was reached by improving the structure, welding process and optimum operation.

Key words: waste heat boiler, spiral finned tube, leakage, improvement, T91/P91 material
