HIGH-PRESSURE AND DENSE-PHASE PNEUMATIC CONVEYING OF PULVERIZED COAL OF DIFFERENT SIZES
Introduction High-pressure and dense-phase pneumatic conveying of pulverized coal is a key technology in the field of large-scale entrained bed coal gasification. The pneumatic conveying has been successfully used in the chemical engineering, energy, metallurgy and other industrial processes with advantages, such as reliability, flexibility of layout,ease of automation, low maintenance, hygienic and environmental friendly. In recent years, numerous studies, for instance, experiment,signal analysis and numerical simulation, have been conducted on different pneumatic conveying systems to characterize the flow behavior of the gas-solids two-phase flow in the pipes with different sizes and for different pipe bends. Many valuable achievements on the characteristics of pneumatic conveying have been obtained. Generally, the achievements are mainly about the low pressure and dilute-phase pneumatic conveying 1-8. Very few references and experiences in high-pressure and dense-phase conveying are available, especially for pulverized coal of different particle size.Both experimentation and theory in this field still need the further research.
