1/2/2021 · Abstract. The most severe problem in firetube boilers is fouling formation and under deposit corrosion (UDC) on the tube surfaces, leading to water or steam leakage into the fire–side and emergency shutdowns. In this work, fouling propensity and UDC mechanism on the outer surfaces of firetubes of seawater boilers are investigated.

1/2/2021 · During a one-year window time of the boiler operation, it seems that the composition of water in boiler was acceptable just in 5 weeks (5 dots located in the domain of control box). PCC is useful to control the concentration of free caustic via consumption of phosphate ions by corrosion products leading to precipitation of phosphate-rich deposits, which is known as the phosphates hideout.

15/3/2012 · Normally, the boiler performance is judged by the heat flux distribution along the different surfaces of the boiler in both sections of the furnace and the return chamber (tube bank section). Therefore, the distribution of the total heat flux (the sum of radiative and convective fluxes) and the radiative heat flux are plotted for the two cases of air–fuel and oxyfuel combustion and shown in
