AI Technical Summary

Technical Problem

The existing reduction tube burner cannot consume the increased fly ash. Insufficient mixing of air, flue gas and coal gas leads to low combustion performance of the burner and a large amount of combustion pollutants in the flue gas.

Method used

A reduction tank burner was designed, including an air inlet pipe and a combustion mechanism. By setting up a gas pipe and an air inlet pipe, adding a coal air pipe and a filter assembly, and using an air inlet impeller and a motor to drive the blades to rotate, the air and flue gas are mixed and filtered, thereby improving combustion efficiency and impurity removal effect.

Benefits of technology

The increased fly ash mixing ratio enhanced the mixing effect of air and flue gas, reduced nitrogen oxide emissions, extended the service life of the equipment, and saved energy.

Abstract

This invention discloses a reduction tank burner, relating to the field of burner technology, including an air inlet pipe and a combustion mechanism. The two ends of the air inlet pipe are fixedly installed to the top of the combustion mechanism. This invention, by setting up gas pipes and adding multiple gas-air pipes outside the confluence pipe, increases the gas volume of the burner, effectively improving the fly ash mixing ratio and meeting the fly ash incorporation requirements after the increase in gas volume. Through the air inlet pipe, air and flue gas move spirally into the fan casing under the action of the air inlet impeller. The air and flue gas undergo initial mixing in the mixing pipe, while the rotating air inlet impeller continuously disperses the flue gas and air, resulting in secondary mixing. This allows the flue gas to mix with the air more quickly and effectively, while simultaneously recycling the discharged flue gas, improving burner combustion efficiency, saving energy, and reducing nitrogen oxide emissions.
