- the flange 36 between the burner trough 33 and the inner wall 25 of the inner space portion 29 in the upper region of the burner trough 33 is cross-sectionally closed, so that there is no short-circuit connection between the outer space part 31 and the inner space part 29 in the region of the annular gap 40.
- the flange connection 36 may be offset so far from the upper edge of the burner trough 33 that in addition to the annular gap 40 above the flange 36, the peripheral wall 34 of the burner trough 33 passing through inflow openings can be provided on the burner trough 33.
- the transition cross section from the burner trough 33 to the gas mixing chamber 39 is preferably constricted in the context of the invention, wherein this constriction can be realized by a retracted, not shown edge region of the burner trough 33, or by a over the burner trough 33 radially inwardly projecting part 50th the boundary of the gas mixing chamber 39.
- Ausmundend on the gas mixing chamber 39 is the upper part 2 assigned a closable Serviceo réelle 51, which is closed in the exemplary embodiment by a stopper-like closure member 52 which is set in the simplest manner, for example by screwing and is to be inserted into a hulsenIndia leadership 53 of the upper part 2.
- a fuel feed 54 in the form of at least one downpipe 55 is provided following a dosing device, not shown, which emits laterally obliquely from above onto the upper region of the burner trough 33 and the mouth side for flame shielding and / or distribution of the particular in shape associated with pellets fuel supply corresponding shielding parts 56 are assigned.
- the air is supplied via partial air feeds, of which the first partial air feeds through the bottom 35 of the burner trough 33 associated openings 57 are formed.
- partial air feeds formed by openings 58 are provided in the peripheral wall 34 of the burner trough 33, wherein the bottom-side openings 57 form first partial air feeds and the peripheral openings second partial air feeds and are respectively fed from the inner room part 29 demarcated as storage space 61.
- the representation of the openings 57, 58 as bores is symbolic, and slots, inwardly and / or outwardly directed forms or the like may be provided instead of such bores, which, based on the respective energization, form air guides, via which the air movement within the burner trough 33 is to be influenced, for example as helical or vortex-shaped, is to make upward against the gas mixing chamber 39 extending air flow.
- first partial air feeds guide plates 59 are illustrated in the exemplary embodiment, on the one hand are suitable to influence the flow direction of the air entering through the openings 57, and also to achieve a shielding of the openings 57 against bottom-mounted fuel is so that obstruction of the openings 57 are avoided.
- third partial air feeds are provided, starting from the outer room part 31, these third partial air feeds for example and preferably through the annular gap 40, but optionally also through the The upper edge region of the burner trough 33 associated openings are formed and wherein the vortex movement of the air in the sense of a spiraling upward rising air flow can be increased via these third partial air supply according to the current flow through the outer space part 31 in the burner trough 33.
- the outer space part 31 also forms a connection of fourth partial air feeds to the blower space 24, wherein the fourth partial air feeds preferably extend to the flame tube 47, which is not shown.
- the supplied via the first and second partial air intakes air proportion is preferably a total of about 30%.
- the annular gap 40 preferably about 30 to 50% of the required amount of air supplied, wherein the average value of about 40% forms a preferred value.
- a percentage between about 20 and 30% is appropriate.
- the described burner system works, also due to the long residence time of the fuel gases, very low pollutant, and is characterized, with good metering of the fuel supply, by a simple adjustability of the heating power and a low-residue combustion.
