Here we provide the overall description of Nigerian coal, also this piece of article contains the information about our Odagbo coal.
Coal samples for the research were obtained through the Nigerian Coal Corporation, Enugu, for five different deposits in Nigeria, which include Odagbo (Kogi State), Owukpa (Benue State), Ezimo (Enugu State), Amansiodo (Enugu State), and Inyi (Enugu State).
based on analysis of tests carried out, the coals have been
classified in terms of rank, grade, and type.
Odagbo coal is a
subbituminous B, medium sulphur, low ash coal rich in
huminites.
The ease of combustion of the coal samples in decreasing
order is Odagbo < Owukpa < Inyi < Ezimo < Amansiodo.
While the ignition temperatures of the coals increase with
decreasing volatile matter content, their calorific values are
strongly correlated with the fixed carbon, elemental carbon,
volatile matter, and hydrogen contents in decreasing order.
