Способ обработки газообразных отходов, содержащих вредные вещества для регенеративного теплообменника и находящихся в состоянии теплообмена с другой средой, с неподвижными или циркулирующими аккумулирующими массами, состоящими по меньшей мере частично из каталитического материала, к которому подается восстановитель с горячей поверхности, помогает предотвратить попадание восстановителя в поток дымового газа, если восстановитель подается к катализатору отдельно от отходящего газа, содержащего вредные вещества, и напрямую, не соприкасаясь с прочими поверхностями нагрева. Для этих целей в обеих половинах колпака может быть расположено сопловое устройство по меньшей мере с одним отводом, проходящее, смотря по обстоятельствам, через общий радиус теплообменника. 2 с. п., 6 з. п. ф-лы, 4 ил.The method of treating waste gases containing hazardous substances for a regenerative heat exchanger and in heat exchange with another medium, with fixed or circulating storage masses consisting at least partially of a catalytic material to which the reducing agent is supplied from the hot surface helps prevent the reducing agent from entering the stream flue gas, if the reducing agent is supplied to the catalyst separately from the exhaust gas containing harmful substances, and not directly in contact with sayas with other heating surfaces. For these purposes, a nozzle device with at least one outlet may be located in both halves of the cap, passing, depending on the circumstances, through the total radius of the heat exchanger. 2 sec. Clause 6 h. the item of f-ly, 4 ill.
