摘要:
An aeration mechanism of a combustion chamber in a pellet burner concerns a burner comprising a steel body (1) with an inlet hole (2) for pellets and a rotary combustion chamber (3), surrounded by a cylindrical, fixed cover (4) permanently connected with the body , in addition, a space between the combustion chamber and the cover is a ring-shaped duct (conduit) (5) supplying air to the combustion chamber throughout the inlet holes (6) and/or inflating nozzles placed on its circumference. In a solution according to the invention the rotary combustion chamber has several longitudinal diaphragms (7) arranged in a form of shutters swingably mounted on the outer surface of the combustion chamber and obscuring the inlet holes of air, working together with a fixed control ring (8) situated perpendicularly to the longitudinal axis of the chamber around its rear part, in addition, an inner surface (9) of the control ring has a shape of arcs of two radius (R, r) connected with each other by short, straight segments and functions as a cam pressing the diaphragms to the combustion chamber surface or releasing them in accordance with a sequence of the preset phases. The combustion chamber has a form of a prism or a truncated pyramid a base of which is a regular polygon. The diaphragms are arranged in twos on either side wall (10) of the combustion chamber .

The subject of the invention is a cover of the combustion chamber in the pellets burner, having a housing (1) with an inlet whole (2) for pellets and rotary combustion chamber (3) surrounded with a cylindrical cover (4), connected with the housing, in addition, a space between the combustion chamber (3) and the cover (4) is a ring-shaped duct supplying air into the combustion chamber circumferentially placed on it. The ring-shaped duct (5) supplying air into the combustion chamber is closed in front of the cover (4) with its flange ring (6) directed towards inside of the chamber and a sealing ring operating together with it, connected permanently with the outer surface of the combustion chamber. According to the invention, a rear part (8) of the cover (4) is permanently connected with a compensatory plate (9), a surface of which is perpendicular to the longitudinal axis of the cover (4) whereas, the compensatory plate (9) is elastically connected with the burner housing (1).

The object of the present invention is a segmented burner furnace chamber grate whose entire surface is formed by a series of movable grate bars connected using any known method, with inlet ventilation holes, loosely fitted by means of a mounting assembly, positioned one next to another to form sections (sectors), at least two of which are mechanically driven and repeatedly move in a reciprocating fashion. According to the invention, the grate bars forming the grate (1) are in the form of plates (2a, 2b, 2c ... 2n), each in the shape of a prism or a truncated pyramid with a rectangular base, while one edge of each plate is fitted with a coupling protrusion (tongue) (5), and its parallel edge is fitted with a groove (6) whose shape matches that of the coupling protrusion (tongue) (5) of a neighboring plate (2), thus enabling joining the plates (2a, 2b, 2c ... 2n) in a jigsaw-puzzle fashion, to form rows (R1, R2, R3, R4, .... Rn), and while the other two parallel edges of each plate are smooth and loosely fitted to form longitudinal expansion gaps (7) between plate surfaces.

The pellet burner afterburner according to the present invention is installed in the burner at the border of a combustion chamber ( 2 ) and a fuel inlet ( 3 ) being the terminal section of an internal feeding pipe ( 4 ), seated on the feeding pipe ( 4 ). Furthermore, the afterburner according to the present invention is characterized in that it contains a guiding pull rod ( 5 ), which makes a reciprocating movement and is connected by means of an articulated joint ( 6 ) and guides ( 7 ) to a movable ring ( 8 ), which has cut-outs ( 9 ) on its perimeter, adapted to both the number and the shape of the profiled guiding vanes ( 10 ), which are fitted at equal intervals to the mounting plate ( 11 ), whereby the ring ( 8 ) is slide-mounted on to the guiding vanes ( 10 ).

A drive unit of a worm feeder supplying the combustion chamber of a pellet burner, being the subject of the invention, relates to a burner comprising a steel body, which is a fixed housing with an inlet hole for pellets and a rotary combustion chamber, equipped with a multipoint blow-in of air throughout holes and/or nozzles, to which pellets are being dosed by the worm feeder. According to the invention the drive unit has a centrifugal fan with an internal motor and a mounting plate (6) of the housing, whereas the centrifugal fan (1) and its motor (2) are connected throughout a centring sleeve to a/the reduction gear (7).
