Evaluation of Coal Supplied to Soma Thermal Power Plant (Türkiye) with Statistical Process Control Techniques

Abstract

Statistical Process Control (SPC) is a method developed to ensure that production activities are carried out in
accordance with predetermined quality specifications and to minimize the production of defective products/goods by
largely preventing non-standard production. Various scientific methods are used when the calorific values of coal fed to
thermal power plants are examined in terms of quality. In this study, the calorific values and other specifications of the
coal fed to the Soma Thermal Power Plant (Manisa/Türkiye) and whether the process is under control or not are examined
by considering the two-year data for tracking and monitoring the process with the Statistical Process Control (SPC)
method, taking into account both the design conditions of the power plant and the production parameters. The adequacy
of the processes for which stability analysis was performed was evaluated in the next stage. When the two-year control
charts (
