Abstract
An incinerator comprises a pre-drying grate, a combustion grate or drum following the pre-drying grate, and a drop intermediate the pre-drying grate and the combustion grate or drum. The drop is the front wall of an air distribution box extending over the width of the pre-drying grate, this wall including air throughflow apertures whereby air passes from the box to a combustion chamber above the combustion grate or drum. The speed of the air flow from the apertures varies over the wall, with the highest speed flows being adjacent to the side walls of the chamber.
Claims39
A combustion apparatus, comprising a pre-drying grate (1, DR1), a combustion device (9, DR9) following the grate (1, DR1), a combustion chamber (100) above said device (9, DR9), and a drop (8, 8a, 8c, 8d) which is intermediate the grate (1, DR1) and the combustion device (9, DR9) and down which material to be combusted falls, wherein there is the improvement that:
- at least part of said drop (8, 8a, 8c, 8d) is constituted as a front wall (7, 7a, 7b, 7c) of an air distribution box (3, 3a, 3b, 3c, 3d) extending over substantially the whole width (b1, b2) of the grate (1, DR1) and connected to air supply means (14, 15, 30, 51, 52) for supplying air to said box (3, 3a, 3b, 3c, 3d), and
- said wall (7, 7a, 7b, 7c) is provided with air throughflow apertures (13s, 17, 17a, 23, 33a, 50a, 75, 76a) so dimensioned that air passes from said box (3,3a, 3b, 3c, 3d) to said chamber (100) in zones of different air speed, including zones of relatively higher air speed on each lateral side of said combustion chamber.
