A water-cooled horizontal cylinder in which fuel is fired and heat is released at extremely high velocities. When firing coal, the crushed coal is introduced tangentially into the burner at the front end of the cyclone, the combustion air enacts a whirling motion around the coal, raising the velocity of the coal and in-turn its temperature. The products of combustion are discharged through a water-cooled reentrant throat at the rear of the cyclone into the boiler furnace. A layer of molten slag coats the burner and flows through traps at the bottom of the burners, reducing the amount of slag that would otherwise form on the boiler tubes.
