Abstract

Abstract:

Waste heat boiler is one of the critical equipment in ethylene plant. Its leakage failure will lead to the emergency shutdown of cracking furnace and affect the stable operation of ethylene plant. There are multiple mechanisms contributing to the leakage failure of waste heat boiler. This paper analyzes the causes of the failure of waste heat boiler through methods such as metallographic testing and phase analysis, and discusses the solutions to the leakage failure of waste heat boiler in ethylene plant, so as to extend the service life of waste heat boiler, enhance its operation reliability and ensure the long-term stable operation of ethylene plant.

Key words: cracking furnace, waste heat boiler, leakage, failure
