Abstract
A coke oven and a method of operating the same, capable not only of achieving a uniform combustion temperature heightwise within a combustion chamber when a rich gas or a lean gas is burnt, but also of reducing NO content in the waste gas, while eliminating localized high-temperature combustion. The combustion chamber of the coke oven comprises a rich-gas port located near an oven wall bordering a carbonization chamber in the bottom of combustion chamber, and the midpoint P , connecting the center P of a lean-gas port and the center P of an air port , is on the side opposite to the rich-gas port relative to the center line CL of the combustion chamber.
