Indian Cement Industry today prefers petcoke as an alternate fuel for cement
manufacturing for various reasons. The important among them are as follows: (a) High calorific value > 8,000 kcal/kg
(3500-4500 kcal/kg conventional), low
ash content and low volatile matter (but
high sulphur content, up to 7%) (b)
Resource conservation thru production
of higher grade cement or utilisation of marginal and low grade raw materials (c) Saving in transport cost due to lesser fuel load (d)
Saving in the initial cost (fuel cost
constitutes about 48% of the cost of cement production)However the burning of petcoke also throws some challenges,
like: (a) Low
hard groove index: difficult to
grind (b) Low
volatile matter: difficult
to burn (c)
High sulphur: Condensation of sulpahtes and chlorides in preheater
section results in jamming of process flows, termed as volatile cycles
