LIMITING THE PRESENCE OF OXIDES OF NITROGEN IN REGENERATIVE HEATING SYSTEMS

摘要

The presence of oxides of nitrogen in the exhaust gas leaving a regenerator having a heat storage bed 11 and combustion chamber 26 is limited by injecting water or water vapour into the regenerator 1 during its firing phase and causing the water or water vapour to reach the combustion chamber 26 by way its heat storage bed 11 which has been preheated during a previous heat collecting phase.
