The intensified fluidized bed method is proposed to burn the crushed polydisperse low-grade brown coal. The principle involves the creation of a fluidized bed of coal through the use of intensive stirring and without the need for inert materials. The mode is jointly that of a fluidized bed and gushing layers with the movement of air at three levels. The primary air flow includes a proportion of recirculated flue gases to reduce the emissions of nitrogen oxides and prevent the melting of the coal ash particles. The addition of a suspension of hydrated lime or local quality clay to the layer binds the sulfur oxides, stimulating the granulation of the ashes and reducing the size of ablation. The tests were carried out in a quartz chamber and this topic continues to be the object of ongoing research.
