Abstract
A method for management of an anode furnace, from which an adjustable volume of flue gas is directed into a flue system, comprises the steps of measuring the actual flue gas temperatures in flues of each section as actual temperatures, taking related set temperatures from a set temperature schedule, calculating a time integral of deviation between actual and set temperatures, modifying the actual temperature during a baking process such that the time integral is reduced to zero at the end of the process, registering at least one of the oxygen content and the fuel load in each flue, and setting burner capacity according to the set temperature and to the available oxygen content in the flue.

A method for controlling an anode furnace, from which an adjustable volume of flue gas is directed into a flue system comprising sections of flues, the method comprising the steps of:
- measuring actual flue gas temperatures in the flues of each of the sections;
- taking related set temperatures from a set temperature schedule;
- calculating a firing index comprising the time integral of deviation between the actual and the set temperatures;
- modifying the actual temperatures during a baking process such that the time integral is reduced to zero at the end of the baking process;
- registering at least one of (i) the oxygen content and (ii) the fuel load in each flue;
- and
- setting burner capacity according to the set temperature and to the available oxygen content in the flue.
