FIELD: energy. ^ SUBSTANCE: furnace is vertical. The front and rear walls of the furnace form a constriction. The projection of the constriction of the front wall is below the projection of the constriction of the rear wall. Stepped supply of air accompanied by heat dissipation creates low-temperature combustion conditions in the furnace. The distinctive feature of the furnace is combination of local fuel inlets through downward directed fuel supply devices located on the inclined section of the front wall, with inlet of a portion of air for combustion form the side of the front wall along the bottom of the entire width of the furnace. Air embrasures with turbulence-creating devices are fitted directly under the fuel supply devices in order to uniformly distribute fuel on the width of the furnace. ^ EFFECT: prevention of agglomeration and fusion of ash which lead to slag formation. ^ 2 cl, 2 dwg |
