Pneumatic conveyor dynamic models for a pulverized coal plant
2012 (English)In: 6th Int. Congress on the Science and Technology of Ironmaking 2012, ICSTI 2012: Including Proceedings from the 42nd Ironmaking and Raw Materials Seminar, and the 13th Brazilian Symp. on Iron Ore, 2012, Vol. 1, 91-103 p.Conference paper (Refereed)
This article describes new advanced non-linear dynamic models for pulverized coal injection (PCI) plant into blast furnaces. A complete new approach for modelling is developed for the actual state-of-art PCI injection station. These models take into account all the physical dynamic laws and pneumatic conveyor variables allied to a modern updated digital control system (DCS). The models were constructed to operate in real time for the same DCS that controls the industrial PCI plant. Process validations include pressure and modern mass flow meter specially designed to check the models. New verification variables allowed by these equipments shows the functionality of the dynamic model-based, thermal, pressure profile and the particle velocity models. The models can be used mainly to improve coal flow stability control by means of modern control strategies and to prevent clogging lance caused by low coal particle speed and high solid to gas ratio.
