Abstract

Thermal power stations and process industries all over the world are facing the problem of boiler tube failure frequently. This affects the performance of the power plants leading to a huge amount of money loss. This study performs detailed efficiency testing and simulation of thermal flow inside an industrial boiler. The simulations were carried out using commercial available CFD software. The analysis of the temperature distribution for every location inside the domain is conducted by setting constant heat fluxes, and varying parameters such as mass flow rate of steam, steam inlet temperature and scale thickness. The results showed that the temperature distribution at the tube wall decreases with increase in mass flow rate of steam; decrease in steam inlet temperature; and increase in scale thickness.
