Abstract
The invention relates to a method of reducing emissions of byproduct gas when charging oven chambers of a battery of coking ovens, on the proviso that the oven chamber () to be charged is opened on the machine side (MS) of the battery of coking ovens, and a block of compressed coal () is introduced into the opened oven chamber (). Byproduct gases released during introduction of the block of compressed coal () into the hot oven chamber (), are discharged through a byproduct-gas manifold () attached to the oven chamber () and are then preferably freed of dust and incinerated. Crude gases formed in the closed oven chambers during coking are discharged through a crude-gas manifold () attached to the oven chambers () and are passed on for treatment by at least one gas scrubber. According to the invention, conduits connecting the crude-gas manifold () and the byproduct-gas manifold () to the oven chambers () are alternately opened and closed such that the byproduct gases that form during the charging of the oven chambers () are admitted only into the byproduct-gas manifold (), and that the crude gases that form during coking in the closed oven chambers are fed only into the crude-gas manifold ().
