The plant uses lowsulfur Wyoming coal between 15,000 and 30,000 tons a day. Production Process Coal that is conveyed from the yard is buffered in six bunkers prior to the burner. To ensure a continuous production process, these bunkers have to be filled to a certain level at all times. Since the level measurement is critical to maintain

Coal is one of the reserve sources of fuel for many industrial applications. For example, in a coalfired power plant, coal significantly contributes to the operating costs of the plant. The control over the fuel cost and the level of fuel management can directly affect the economic benefits of the coalfired power plant. In this study, we have developed a generalized calculation methodology ...

To assess the deformation of a coal bunker and propose effective preventative measures for such, a realtime monitoring system was designed. Moreover, methods were proposed for monitoring the coalbunker inclination, settlement, groundwater level, temperature, and material level. By using a vector autoregression model and timeseries data for the coalbunker deformation, a longterm ...

Closed coal bunkers emerged as a novel form of coal storage for coalfired power stations. Nevertheless, heat builds continually in the storage process because of the constant oxidation of coal and combined with the impact of a confined coal bunker environment, it is difficult for heat to dissipate, resulting in frequent coal bunker fires. Consequently, research on coal pile combustion ...
