Experimental design and optimization of a novel solids feeder device in energy efficient pneumatic conveying systems

Experimental Study on the Agglomeration Behavior of Elongated Biomass Particles in a Lifting Tube

“…With the realization of mankind that the use of traditional energy sources has had a serious impact on the environment and climate change, the use of clean energy has received increasing attention from countries around the world. − As a kind of green, low-carbon, and clean energy, biomass can be widely used in industry, life, transportation, and other fields. − In biomass energy, the pneumatic conveying device is an efficient gas–solid reaction and heat and mass transfer equipment, which has many advantages, such as fast gas–solid transfer speed, high contact efficiency, and high utilization of raw materials and equipment. − Therefore, pneumatic conveying devices are widely used in the conversion process of biomass energy, which makes an essential contribution to the development of the clean energy industry. − After nearly 70 years of fundamental theoretical research and technological development, pneumatic conveying devices are now widely used in many industries, such as the chemical industry, energy, food processing, material processing, environmental protection, and so on. − Some of the advantages of pneumatic conveyors are the low number of moving parts, flexible setup, and fully enclosed transportation, all of which create environmentally safe applications . It serves not only as an alternative for transporting pellet materials between locations or blending different pellet types but also facilitates the prefabrication of biomass pellets, offering functionalities such as moisture content control, sorting, feed, and mixing. − In the realm of contemporary engineering applications, there is a prevailing preference for dilute-phase conveying, which proves to be the most economical mode due to the inherent ease of cleaning and maintenance associated with the equipment compared to concentrated-phase conveying systems .…”
