Improvements in 1995 and to the devices for reduce the emission of pollutants atmospheric by a combustion

摘要

A pair of conduits, coaxially arranged, provide flow paths for carrying combustible reactants to a combustion zone. The central conduit, otherwise known as a distribution tube, extends to within the combustion zone and includes a disc element at the combustion zone end thereof for deflecting an oxidizing reactant moving axially along the exterior of the distribution tube. A fuel reactant introduced into the distribution tube is carried to the combustion zone end thereof where it issues through radially aligned orifices and impinges the oxidizing reactant to produce a hollow cone flame. Additionally, a mixing element may be included within the distribution tube to impart centrifugal motion to liquid fuels which are then subject to being atomized in the region of the radial ports. Proper control and selection of both the dynamic and physical (dimensional) parameters provides for a combustion process to minimize oxides of nitrogen, and increases heat transfer rates in the combustion zone.
