Investigation on the heat transfer coefficient and uniformity in a polygonal furnace of a 350 MW supercritical CFB boiler
2020, Applied Thermal EngineeringCitation Excerpt :It is not beneficial for the safe operation of supercritical CFB boilers. Many scholars carried out a number of experiments to investigate the effect of operating parameters, including bed temperature, particle concentration, particle diameter, superficial velocity, etc, on the bed-to-wall heat transfer coefficient in the furnace of a lab-scale or pilot-scale CFB [6–12]. The investigation results show that the heat transfer coefficient increases with the increase of particle concentration and bed temperature [7,9].

2019, Applied Thermal EngineeringCitation Excerpt :The size of the deposited metal is determined by the thermocouple diameter and the characteristic deposition thickness. Numerical simulation is a powerful approach to study the heat transfer phenomena and has been adopted by a number of tube-wall temperature field studies [15,25–28,30–37]. In the present study, once the deposited metal is applied, the tube wall temperature will increase (details to be shown in Section 4), which is not only a risk for the tube safety, but also brings systematic bias error of the measured tube temperature.
