Sensors | Free Full-Text | Potential of Dual and Multi
Dual and multi energy X-ray transmission imaging (DE-/ME-XRT) are powerful tools to acquire quantitative material characteristics of diverse samples without destruction. As those X-ray imaging techniques are based on the projection onto the imaging plane, only two-dimensional data can be obtained. To acquire three-dimensional information and a complete examination on topology and …

Combustion Efficiency - an overview | ScienceDirect Topics
Steelmaking begins by placing the solid components of the charge, the limestone, any ore requirement, and rusty scrap steel into the depression, cold. The scrap is preferably rusty to provide oxygen which will assist in impurity removal. Some iron ore (e.g., Fe 2 O 3) may also be added for the same reason. The fuel, usually natural gas, coal ...
