The ECA Elemental Crossbelt Analyzer is the first on-the-belt, full-stream analyzer to use Prompt Gamma Neutron Activation Analysis (PGNAA) technology, a technique pioneered and commercialized by Thermo Fisher Scientific™ in 1984 that has been widely employed for online elemental coal analysis of sample streams.
A 61 cm diameter, down-flow, axial-flame combustion system utilizing various ratios of oxygen to CO 2 for combustion of various types of coal has been studied. In companion work flame stability and the standoff distance between the burner and the point of flame ignition has been determined using low-speed video analysis of the flame.
In this work, a fully software-controlled laser-induced breakdown spectroscopy (LIBS) based coal quality analyzer comprising a LIBS apparatus, a sampling equipment, and a control module, has been designed for possible application to power plants for offering rapid and precise coal quality analysis results.
From here the coal is conveyed to a 500 tone bunker located over the coke ovens. Carbonisation: Carbonisation is the thermal process for the conversion of coal into coke, involving heating coal at high temperature for many hours in the absence of air
