Drying of Municipal Sewage Sludge: from a Laboratory Scale Batch Indirect Dryer to the Paddle Dryer

Among available technologies, disk and paddle dryers are often encountered in France to process municipal sewage sludge but their thermal design is still a question of know how rather than scientific knowledge. From experiments performed on an industrial Naratherm paddle dryer and the literature, a simple model has been developed. The dryer is divided into two parts depending on the sludge cons...

Development and Improvement of a Washer - Dryer with Kansei Ergonomics

Recently, washer-dryer machines with slanted drums have become popular in Japan. We measured and analyzed posture while using such machines with three-dimensional motion capture measuring devices. Subjective Kansei and usability questionnaires were also used. After the measurements, working postures were analyzed with a human kinematic model (3D SSPP). Three types of machines were used for the ...

CFD Simulation and Optimization of Factors Affecting the Performance of a Fluidized Bed Dryer

Computational Fluid Dynamics (CFD) is a computational technology that enables researchers to study the dynamics of things that flow. By using CFD, it is possible to build a computational model that represents a system under study. It not only predicts fluid flow behavior, but also the transfer of heat, mass, phase change, chemical reaction, mechanical movement, and stress or deformation of ...

Experimental Study of Chemical Absorption of CO2 in a Bench-Scale Spray Dryer Absorber

The removal of CO2 through chemical absorption in a bench-scale spray dryer absorber was investigated experimentally using the lime slurry as absorbent. The effect of important operating parameters on CO2 removal efficiency has been investigated; in selected ranges of operating parameters, increasing gas inlet temperature and absorbent concentration lead to permanent efficiency decline, increas...
