Colombia is a remarkable coal producer and exporter worldwide; several sectors use this resource for electricity and thermal energy production. Among them, the ceramic industry consumed 118,590 tons in 2011. Most of the pottery production companies in this country are located effects to the population nearby. Despite of the importance of these industries to the small rural economies, the govern...

A new developed and designed real-time expert intelligent control system (REICS) for industrial process control has been introduced. The global architectures of the hardware and software of the system have been proposed. A multi-level method of knowledge representation based on the combination of frame, production rules and real-time procedures has been discussed, and used to represent the cont...

JCI/UPCYCLE Associates' technological and commercial approach focuses on the utilization of dredged material as a feedstock in the manufacture of a value added building material, lightweight aggregate (LWA). Our approach, based on proven unit operations, is capable of yielding an "upcycled" product with a demonstrated market demand. Key to the success of the approach is the incorporation of exi...

A 2D axisymmetric computational fluid dynamics (CFD) model, coupled to a 1D bed has been developed capture the key processes that occur within rotary lime kilns. The model simulates calcination reaction using shrinking core and predicts start of degree at end kiln. heat transfer due radiation, convection conduction between gas, wall, chains, bed. gas models are by mass sinks simulate transfer, ...

Exposure assessment is a main component of epidemiologic studies and variability in exposure. This assessment is considered as a common approach for such phenomenon. A total of 129 dust samples were collected randomly from 197 personnel from a cement factory located in Ilam province, during 2009 in Iran. The between- and within-group components of variability were determined to assess the contr...

The thickness of the lining is reduced from 230 mm to 80 due long-term wear, resulting in low thermal efficiency rotary kiln. resistance, which positively correlated with lining, one most important factors determining kiln can be improved by introducing insulation material lower conductivity into lining. average heat flux used as evaluation index 4×60 m under no-load conditions this work. A num...
