  • WO2016179909A1 - Burner design for pulverized coal-fired

    A system and accompanying method for burners (101,201,304) for pulverized coal-fired boiler (301) without the need to preheat the boiler (301) in order to generate a stable flame from pulverized coal is provided. Secondary air streams (2°) are introduced within the burners (101,201,304) in a significantly opposite direction to the primary air/coal streams (1°) causing a reflux effect which
