化学工業炉用低NO_xバーナの研究

抄録

As a result of study on the NO_x formation choracteristics of pre-mixed flames, we have succeeded in developing new low NO_x berners. These burners can be used for various kinds of chemical furnaces as gas and/or oil firing burners with a natural draft system.
According to the results of test of these burners in the semicommercialized scale test furnace, their NO_x emissions were very small, being 30 ppm in propane or naphtha firing, 45 ppm in A heavy oil firing and 90 ppm in C heavy oil firing (of the time of combustion of 5% excess O₂)
