Current Status and Prospects of Hydrodynamic Research in Coal-Fired Boiler Power Plants

doi:10.3969/j.issn.1008-0198.2024.05.001

Abstract

Abstract: A study is conducted on the dynamic characteristics of tube wall superheated water in response to the phenomenon of overheating on the heating surface of coal-fired power plant boilers.Through research, it has been found that inaccurate thermal calculations,improper selection of burners,unreasonable arrange‍ment of heating surfaces, and insufficient temperature control conditions ultimately lead to overheating of the boiler heating surface due to thermal deviation oxidation. Through hydrodynamic calcula‍tions, a wall temperature distribution model is established to reveal the fundamental cause of overheating and tube bursting on the heating surface, providing a detailed theoretical basis for analyzing wall temperature changes and developing measurement methods.

Key words: boiler, over-temperature, hydrodynamics, wall temperature prediction, numerical simulation
