Reactor for the catalytic removal of NOx with preheating

摘要

Reactor for the catalytic removal of nitrogen oxides from flue gases and exhaust gases, composed of a housing furnished in each case with an inlet orifice and an outlet orifice and one or more successively arranged catalyst beds having an apparatus located on the inlet side for uniform distribution of the gas stream to be treated over the flow cross-section, a steam/gas heat exchanger for the reactor preheating being arranged within the reactor housing between the inlet orifice and the apparatus for the uniform distribution of the gas stream to be treated. <IMAGE>
