Also, partial streams of these two gases can be diverted and fed to purposes that are not in the field of coke production plant. In the lines for the carbon dioxide or the carbon monoxide measuring instruments for measuring the concentration of gases can be accommodated. These readings can be consulted to decide on the temporary use of these gases. This can be done manually, but also by computing devices.

It is also possible to mix the carbon monoxide to heat the coke oven fuel gases that are incurred in other processes as by-products, and still have a certain calorific value. Thus, for example, it is possible to feed blast furnace gas from a blast furnace process to the carbon monoxide before it is added to the coke oven. It is also possible in a further embodiment of the invention to supply coke oven gas to the carbon monoxide for additional heating before it is added to the coke oven.
- the carbon monoxide which is produced by the Boudouard reaction and which was provided with a heating gas as needed, can be used directly and without further treatment before being fed into the coke oven for heating. However, this can also be subjected to heat recovery before it is used for heating in a coke oven.

It can do that Carbon dioxide from the exhaust gas are washed, and the resulting carbon dioxide are added to the carbon dioxide to extinguish the coke. In this way, a balanced balance of carbon dioxide (C0 2 ) can be achieved for the entire system, since the carbon dioxide from the exhaust gas is again used to extinguish the coke and after conversion into carbon monoxide for heating the furnace. As a result, the total output of carbon dioxide is low and ideally not present.
