Abstract
Pneumatic conveying of powders is a unit process extensively used in industries for the handling of particulate material of several segments. Academic studies started with empirical dilute-phase pneumatic conveying and, in order to produce better economic results in industrial settings, evolved to include energy efficiency techniques as a significant component. Much work has been done to understand and model pneumatic conveying systems; however, they are highly empirical and the conclusions are, in most cases, limited to a narrow range of experimental conditions. This paper introduces a systematic method to select the air pressure and flow necessary to operate an energy-optimized pneumatic conveying system. This method has been tested and applied to a pressure conveyor fed by a compact blow tank of 100 L in a 133 m long pipeline with a diameter of 3 inches conveying limestone. The tests demonstrated that it is possible to control this pneumatic conveying system with only two input parameters, while operating at the desired pressure and airflow and maintaining the respective conveying rate and power requirements.
期刊介绍：
The Journal of Pressure Vessel Technology is the premier publication for the highest-quality research and interpretive reports on the design, analysis, materials, fabrication, construction, inspection, operation, and failure prevention of pressure vessels, piping, pipelines, power and heating boilers, heat exchangers, reaction vessels, pumps, valves, and other pressure and temperature-bearing components, as well as the nondestructive evaluation of critical components in mechanical engineering applications. Not only does the Journal cover all topics dealing with the design and analysis of pressure vessels, piping, and components, but it also contains discussions of their related codes and standards.
Applicable pressure technology areas of interest include: Dynamic and seismic analysis; Equipment qualification; Fabrication; Welding processes and integrity; Operation of vessels and piping; Fatigue and fracture prediction; Finite and boundary element methods; Fluid-structure interaction; High pressure engineering; Elevated temperature analysis and design; Inelastic analysis; Life extension; Lifeline earthquake engineering; PVP materials and their property databases; NDE; safety and reliability; Verification and qualification of software.
