Abstract [en]

This paper presents the main features, advantages and an evaluation of applications of an 'Ecotube' technology for combustion improvement and emission reduction. The sensitivity of the Ecotube locations in a combustion chamber and the injection angle of jets on the Ecotube have been analysed numerically. A municipal solid waste incinerator and a coal fired boiler are the focus of this work. A definition of the heat release distribution ratio is proposed to identify the heat release inside the upper furnace of boilers or incinerators. Results show that an Ecotube system allows a far more uniform heat release, lower CO and NOx emissions, and a more uniform temperature distribution, thus a longer life of the furnace chamber. Additionally, the combustion reaction zone occupies as high as 45% of the whole combustion chamber using an Ecotube system, similar to 40% higher than a conventional multijet mixing system.
