Study on Heating Behaviour of Coal during Carbonization in One dimensional model of heat recovery non recovery coke

Abstract The coking process is based on the transformation of coal into coke at high temperature In non recovery coke oven heating is usually asymmetric this may be due to the fact that heating is provided by controlled combustion of volatile matter of charged cake at oven crown and sole flueIn the present investigation a simplified One dimensional model of heat recovery non recovery coke ovens The temperatures measured inside the coking bed have been used to adapt the coking sub model to the coal blend used After such a tuning the overall network model has predicted well the pressure and temperature distributions in the oven
