OBJECTIVES During the last decade, coal-based sponge iron plants, a highly polluted industry, have grown rapidly in Barjora, India. Understanding their workers' perception of health is essential in people-centered healthcare. The aim of the study was to assess their health-related quality-of-life (HRQoL), and to determine factors that independently predict their HRQoL. DESIGN Cross-sectional ...

OBJECTIVES During the past decade, coal-based sponge iron plants, a highly polluted industry, have grown rapidly in Barjora, India. The toxic effects of particulate matters and gaseous pollutants include various respiratory diseases. Understanding workers' perception of respiratory health is essential in people-centred healthcare. The aim of the study was to assess their respiratory health stat...

In this work, the shaft furnace reactor of the MIDREX® process is simulated. This is a counter current gas-solid reactor, which transforms iron ore pellets into sponge iron. Simultaneous mass and energy balance along the reactor leads to a set of ordinary differential equation with two points boundary conditions. The iron ore reduction kinetics was modelated with the unreacted shrinking core mo...

Investigations were conducted to evaluate the performance of a two-stroke, single cylinder, spark ignition (SI) engine, with gasohol (80% gasoline and 20% ethanol by volume) having copper coated engine [CCE, copper-(thickness, 300 μ) coated on piston crown, inner side of cylinder head] provided with catalytic converter with different catalysts of sponge iron and manganese ore and compared with ...

One of the most important methods to produce sponge iron is coal based reduction of iron ore. Direct reduction methods based on coal are being improved due to the abundance of coal sources and its lower cost in comparison with natural gas. Volatile materials in coal play an important role in the reduction of iron oxides. In this study, noncoking coal with high volatile materials from Iran and c...

Polypyrrole was deposited in situ on the macroporous open-cell melamine sponge by oxidation of pyrrole with iron(III) chloride. The oxidant used excess, and reaction mixture after th...
