Temperature Field and Velecity Field of the Eddycrust Swirler Powder Coal Burner

The machanism of whirl burning of the eddycrust swirlcr powder coal burner has been analysed. The coal burner has the advantage of the higher capture, higher carbon burnout, higher volume heat flux and lower pollution. The whirling velocity formulae of the viscosity eddy in the coal burner, the velocity distribution in the cold test under the condition of the secondary tuyere notch leaning backward, the heating power calculating are also introduced.
