  • What Is Coal Preparation? Energygov

    What Is Coal Preparation? • Coal preparation is the removal of undesirable material from the RunofMine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities Through coal preparationfrom coalfired plants can be controlled precombustion, incombustion and postcombustion Precombustion control is by coal selection and coal preparation Incombustion control is by optimising combustion and the injection of sorbents into the flame zone There are various methods of postcombustion control of PM 25 emissions, including conventional particle emission control devicesEmission standards and control of PM from coalfired power· The intelligent control system is developed in a coal preparation plant which is operating and has been equipped with an ordinary control system The ordinary control system uses the AB series PLC which were divided into 3 substations, communicating one another with control net The new system should be compatible with ordinary one, so the AB series PLC still is used as the host controlResearch on the intelligent control of the dense medium
