<p>Process and apparatus for ensuring greater uniformity of the burn-up characteristics and for reducing the thermal NOx emissions of a coking plant on the basis of the non-recovery process or the heat-recovery process using a multiplicity of furnaces, each having a furnace chamber delimited by doors and side walls for a bed of coal or a compacted coal cake and an empty chamber located above said furnace chamber, apparatuses for extracting the flue gas from the empty chamber, devices for supplying fresh air into the empty chamber, furthermore a system of sole flues for guiding flue gas or secondary feed air, which is integrated at least partially in the base underneath the furnace chamber, wherein some of the flue gas produced in the furnace is recirculated into the furnace chamber via openings or channels for the combustion process of the furnace.</p> |
