Present day, the production of hot metal (HM) via blast furnace route remains an integral part global steel industry. With pressure to curb greenhouse gas emissions, injection hydrogen is considered a promising solution while ironmaking transitions alternate technologies. A comprehensive heat and mass balance model calibrated operating was used assess operational limits through tuyeres, replaci...

The growth of the aquaculture sector leads to a demand for sustainable feed ingredients. Prebiotics are potential ingredients that can promote improved performance species without use antimicrobials. This study investigated Azolla pinnata as candidate prebiotic source. Prebiotic characteristics and dietary effect commercial diet (CD) with varying pulverised azolla (PA) inclusion was evaluated. ...

Computational simulation has been carried out to investigate the NO formation/depletion in pulverized coal combustion process. Newlands Bituminous is injected along with career air through a central hole of an axi-symmetric burner. A certain amount co-flow methane coaxially as reburn fuel. The effect overall equivalence ratio on formation and are mainly focused this study. Species concentration...

This study examined the morphology and microstructural evolution of resin-bonded palm kernel coconut shell grain-based abrasive grinding wheels their physico-mechanical tribological properties. Raw (PKS) (CNS) samples were obtained, sorted, sun- oven-dried, pulverised, screened into fines 250, 500 850 μm grain sizes, blended at PKS to CNS mixing ratios 1:0, 0:1, 1:2, 1:1 2:1, respectively. The ...

Pulverisation of rocks occurs through dynamic processes associated with earthquake ruptures. At the well-known pulverised rock outcrops along San Andreas Fault (SAF), intensity pulverisation was shown to be highly heterogeneous on outcrop (m–10s m) scale, although detailed documentation this heterogeneity is still lacking. Here we derive a standardized classification method for applicable field...

This report is in two sections: the first describes the flue gas and its treatment in post-combustion capture and the second covers the flue gas in oxyfuel combustion capture. The main components of the flue gas in pulverised coal combustion for postcombustion capture are CO2, N2, O2 and H2O, and air pollutants such as SOx, NOx, particulates, HCl, HF, mercury as well as other contaminants. The ...
