  • Coal Processing an overview | ScienceDirect Topics

    A stateoftheart coal processing facility typically uses a programmable logic controller (PLC) as the heart of the plant control system The PLC is a computer based controller that acquires data (input) representing the status of all the units and control loops in the plant, makes decisions based on the data input and programmed instructions, and sends data (output) to the plant units reflecting the decisionsApart from conventional coking plants, processes of coaldust gasification with oxygen and steam in fluidized bed and steamoxygen gasification of coal breeze in a quasistatic bed under pressure found a wide application In the late 1970s, dozens of coal gasification processes were being developed, which were at a different stage of achievementOils and Gases from Coal | ScienceDirect
