Materials and heat balance in calcination
Calcination requires thermal energy. This is illustrated by solving few problems. For calculation, we need several thermo chemical values like heat of formation, specific heat, and heat content. The following thermo chemical values are used to solve the problems in this lecture:
Thermo chemical values:
CaCO3=CaO+CO2 |
|
Kcal/Kg.mol |
MgCO3=MgO+CO2 |
|
Kcal/Kg.mol |
CO+1/2 O2=CO2 |
 |
Kcal/Kg.mol |
2Al(OH)3=Al2O3+3H2O |
|
Kcal/Kg.mol |
C+O2=CO2 |
|
Kcal/Kg.mol |
H2+1/2 O2=H2O |
