The process control of a coke plant depends on a lot of particular parameters. This work describes an experimental design in a pilot oven aiming at getting the influence of the main control factors of a coke oven battery, relating these parameters with production and heat consumption for future process control automation. The result of the experiment showed statistic significance for the factors temperature and coal blend moisture and for the interactions between temperature and coal blend moisture and between moisture and coal size on the heat consumption and also for the factor temperature on the net coking time. Theses relations can be used to develop coking control at an industrial plant. In addition to the design of experiments in a pilot oven, it was also made an experiment in an industrial battery oven whose methodology showed to be appropriated to an industrial design of experiment. With the experimental data it was possible to write mathematical equations for estimation of heating and net coking time.
