    • 专利摘要:
    Solid fuel such as coal is fed into an inlet shaft 4 of the furnace through a rotary feeder 5 constructed to prevent the admission of air. Primary air channels 18 supply the major part of the air required for combustion of the fuel in a region in which the fuel bed is sufficiently thick to avoid disturbance and the formation of "holes" by this air. Further, narrower air channels 19 supply sufficient, diffused and low velocity air to complete the combustion of the fuel without substantial entrainment of grit and ash. Air is prevented from flowing in contact with the fuel upstream of the channels 18 and the metering edge 75.

    Claims (4)
    [1]
    Claim
    1. A combustion chamber for burning lumpy solid fuel, comprising a combustion chamber with a fuel supply chute having airtight walls inclined to the horizon at an angle greater than the angle of repose of the fuel and equipped with a metering valve made in the form of a rotating hollow drum with a loading hole, having a cutting. the edge and the grate, made in the form of parallel mounted movable grates, moving fuel in the direction of rotation of the drum, forming slots for the passage of primary and secondary air. connected to the respective ducts located under the grill and separated by a partition, the primary air duct connected to an air source, characterized in that, in order to prevent fuel combustion in heat, in the partition between the ducts • at a distance from the grill
    1 bypass hole.
    [2]
    2. Firebox on π. 1, which is characterized in that the partition between the boxes is made of two parts, the upper of which is fixed, and the lower one with the ability to move its upper edge, and the hole in the partition is formed by the gap between its ed parts.
    [3]
    3. Firebox popp. 1 and 2, characterized in that the valve drum is provided with a radial rebound adjacent to the cutting edge of the loading hole.
    [4]
    4. The furnace according to paragraphs. 1-3, about t l and Harn shch and I. with the fact that the slots of the grated grating for the passage of the primary.
    air are made with a width exceeding at least 2 times the width of the slots for the passage of secondary air.
