In boilers operating in modern power plants, thick-walled elements of complex shapes, such as valves, superheater headers, T-pipes, Y-pipes, four-way pipes, and elbows, are especially prone to fatigue processes. Higher operation parameters and more f

Deposits in power boilers are formed during combustion of practically all solid fuels. The source of deposit formation in boilers is the presence of mineral substance in the fuel. A mineral substance undergoes a series of physical and chemical proces

Particulate fouling of convective heat-transfer surfaces is usually assessed by empirical correlations. Nevertheless, constant progress in numerical calculation methods allows for prediction of deposition. This paper presents results of 2D modeling o

The 1D modeling of deposits formation is not able to describe properly the gas and particles flow in the vicinity of heat transfer tubes in boilers. Especially, the recirculation zones in the down-stream side of tubes are not possible to reproduce by
