process, generate alarms and to calculate reference variables. Screens (video display units) were used for process observation and monitoring. The number of cables required for connections was reduced by using serial bus connections. Digital, distributed, busnetworked, microprocessorbased process control systems were first used in the 1980s.

as onsite fuel. Coal has a wide range of moisture (240%), sulfur (%), and ash content (540%). These can affect the value of the coal as a fuel and cause environmental problems in its use. The depth, thickness, and configuration of the coal seams determine the mode of extraction. Shallow, flat coal deposits are mined

The use of coal is negatively perceived, since the use of fossil fuels in power generation and other industry sectors contributes significantly to the CO 2 emissions worldwide. Of the main fossil fuels, coal has the lowest H:C ratio, and consequently coal has the highest CO 2 footprint per unit of combustion energy produced. Coal also contains percentage levels of heteroatoms (forming NO x and ...

Processing is where coal is converted from runofmine (ROM) coal to a product that meets the customer's requirements. Mined coal can include lumps. Crushing to a manageable size is required. Coal crushing can include a two stage process, dependent on deposit size. Coal is crushed in a feeder breaker, a chain conveyor that breaks the biggest ...
