Abstract

See full text

A cooperative emission reduction method for sintering using an energy-carrying composite gas is disclosed. A surface of a sintered material is divided into an ignition section, a heat preservation section, a middle section, a flue gas heating section, and a machine tail section from a machine head to a machine tail of a sintering machine; according to flue gas components, temperature characteristics, and heat requirements of different sections, a hot exhaust gas is introduced to the ignition section for ignition, a hot exhaust gas is introduced to the heat preservation section and a hydrogen-rich gas is cascadingly sprayed synchronously, cascaded spraying of water vapor is coupled based on spraying of a hydrogen-rich gas in the middle section, and the high-temperature flue gas in the machine tail section and the flue gas in the ignition section and/or the heat preservation section are circulated to the heating section.
