in deciding the blend for non-recovery type of ovens. Low VM coals generate less gas and hence, the total thermal energy on its combustion may be insufÞcient for attaining the coking temperatures in the oven. On the other hand, a high VM coal results in coke with high porosity and hence, poor CRI and CSR characteristics.

150,000 Nm3/hr of coke oven gas having total energy 625 Gcal/hr. 250 Gcal/hr would be required internally in the coke oven plant for battery heating & ammonia cracking. This internal heating would be carried out by supplying a mix of coke oven gas, coal gas from Gassifier and purge gas from coke oven gas to SNG conversion plant.
One of such technologies is a stamp charge coke oven. Depending on a coal charging method, coke ovens are roughly classified into a top charge type configured to charge coal from above and a stamp charge type configured to charge coal from a side of an oven and put the coal into the oven while pressing the coal. In a stamp charge oven,

Automation Division, Tata Steel Limited, has successfully implemented COSMOS, a Level-II automation system for Coke Ovens Scheduling and Heat Monitoring. Introduction Machine co-ordinator keeps track of machine operations such as charging, pushing, coal intake and its movement and interface with scheduling system.
Firstly, the productivity is expected to increase. In a slot-type coke oven, heat is supplied from both heating walls and transferred to the coal in the middle of the oven mostly by heat conduction. Therefore the carbonization speed depends on the heat conductivity of coal and coke, which results in a long coking time of 20–24 h.
