Propane-butane heating of coke batteries

Experience has been gained in propane-butane heating of the first coke batteries of a newly constructed coke plant, where no coke-oven gas or blast-furnace gas is available. Under the guidance of specialists at ZAO Ogneuporkoksservis (OKOS), five coke batteries have been successfully heated and put into operation. For the first time in global practice, a coke battery has been converted to continuous propane-butane heating. Propane-butane heating of the coke battery has been tested and confirmed as a reliable means of preparing the first batteries at a newly constructed coke plant for startup and production. In addition, experience shows that continuous propane-butane heating is possible for a battery with a limited supply of coke-oven gas for heating.
