Combustion Characteristics in High Temperature Air Combustion (II)

Temperature Equalization and NO_x Control

Abstract

High temperature air combustion that uses regenerative burner has many characteristics as follows,
(1) Self ignited combustion, (2) Unnecessary for flame holding measure, (3) The state and shape of flame has remarkable change by how to mix fuel and air, (4) Notwithstanding using highly preheated air, instantaneous maximum flame temperature is low, (5) Flame temperature fluctuation is small, (6) Diluted combustion by burned gas or low oxygen combustion generates, (7) Reaction zone thickness in low oxygen combustion becomes thick. Report (I) shows high efficient heat transfer based on temperature raising, then this report (II) shows the characteristics of temperature equalization and low NO_x.
