Pneumatic conveying is widely used in process industries to efficiently transport powders and granular materials during the production process. Although numerous studies have been performed in the past on pneumatic conveying in pipe systems, the design of the pipe network in pulverized coal fuelled power plants is still largely based on empiricism. Due to air pollution and a global warming of the atmosphere, thermal power plants are required to have a more efficient combustion and lower pollution. These requirements can only be met if the mass flow rate of air and pulverized coal is controlled appropriately. A complex conveying system has been built, using pipe diameters of between 150 mm and 200 mm. Techniques for the characterization of solid/gas two-phase flows as laser-light-sheet-techniques for investigations in model plants have been developed and improved. The results of the numerical simulation of the two-phase flow in two pilot plants have made it possible to simulate the two-phase flow behaviour in a complex conveyor line in a power plant.
