1. Temperature Distribution over the Height of the Heating Channels.

Uniform coke heating within coke ovens is of great importance. The temperature difference along the axis of the coke cake increases with increase in oven length and height and may reach 300°C or more, depending on the coke-battery design and technological factors. The introduction of control devices is a well-established approach to more uniform heating of the coke cake, in combination with methods of temperature calculation at the wall of the heating channel. However, this approach depends on information determined experimentally. That introduces more error in determining the temperature distribution over the channel height. Accordingly, attempts are made in the present work to describe the combustion of the heating gas on the basis of the minimum number of simply and reliably measurable factors. A three-parameter equation is obtained. Its structure is universal in terms of the set of factors. Adopting that equation as a model, the action of various factors on the temperature distribution over the height of the heating channel may be studied. [ABSTRACT FROM AUTHOR]
