Definitions
- the invention relates to a radiant burner for Walkerkes ⁇ sel, consisting of a support plate with a gas supply line leading to a gas inflow opening in the support plate and with a curved burner surface arranged on the other side of the support plate made of wire mesh.
- Radiation burners of this type are known, for example, from US Pat. No. 3,360,028.
- the curved burner surface made of wire mesh has an elongated, approximately semi-cylindrical shape, as a result of which the circular gas inflow opening in relation to the burner surface inevitably becomes very small and this results in poor gas distribution, on which even a small slotted diaphragm behind the gas inflow opening does not make any significant difference changes.
- such a burner is poorly suited for today's compact spatial shapes of combustion chambers or boilers, ie one would have to arrange several such semi-cylindrical burners in parallel next to one another in order to be able to approximately achieve a largely uniform radiation exposure of the combustion chamber walls involved . The same applies approximately to a burner according to US Pat. No. 3,291,187.
- a radiation burner according to FR-A-1 361 509 which is practically spherical and also has a small gas inflow opening in relation to the size of the burner surface, also shows poor gas distribution.
- the spherical shape results in considerable reflections on the burner connection side.
- the object of the invention is to improve it in such a way that the largest possible gas inflow opening is available with respect to the size of the burner surface, the shape of the burner surface is as stable as possible in terms of its shape, and between the inflow opening and the burner surface a gas distribution as uniform as possible over the entire burner surface should be achievable.
- a steel burner of the generic type according to the invention in that the burner surface is in the form of a hemisphere and is concentric with this and with a distance that is substantially smaller with respect to the hemispherical diameter of the burner surface and at least one also hemispherical and also am Support plate is attached gas distributor made of perforated sheet metal, and that the diameter of the gas inflow opening corresponds essentially to the diameter of the hemispherical gas distributor.
- FIG. 1 shows in section a special embodiment of the burner as an integral unit with a boiler lock
- Fig. 4 also in section the burner for atmospheric operation
- Fig. 5 is a plan view of the burner according to Fig. 4 and 6 shows in section the arrangement of the burner in the combustion chamber of a boiler.
- the radiant burner consists basically and in a known manner of a support plate 1 with a gas supply line 3 leading to a gas inflow opening 2 in the support plate 1 and with a curved burner surface 4 made of wire mesh arranged on the other side of the support plate 1.
- the burner surface 4 is designed in the form of a hemisphere and concentrically below it and with a distance A which is considerably smaller with respect to the hemispherical diameter D of the burner surface 4, at least one gas distributor which is also hemispherical and also fastened to the support plate 1 5 is arranged from perforated sheet metal, and that the diameter D ⁇ of the gas inflow opening 6 essentially corresponds to the diameter D2 of the hemispherical gas distributor 5 (see FIG. 4).
- the support plate 1 is provided with annular step embossments 7, to which the burner surface 4 and the at least one gas distributor 5 are connected with their peripheral edges 8.
- the peripheral edge 8 of the burner surface 4 (see FIGS. 1, 2) is fastened to the supporting plate 1 simply by folding the peripheral edge of the supporting plate.
- the support plate 1 is in relation to the gas supply side GS in the form of a formed on the burner axis 9 convexly curved gas guide funnel 10, which also forms a step embossing 7 at the outlet, which centers the inner gas distributor 5 '.
- this gas distributor 5 ' has a small edge 7' that is piled up and serves as a centering for the second gas distributor 5 (see also FIG. 3).
- FIG. 3 A special embodiment with regard to the fastening of the gas distributors 5, 5 'is illustrated in FIG. 3.
- the outer gas distributor 5 is attached to the support plate, which is relatively extends close to the actual burner surface 4 formed by the wire mesh and is therefore also exposed to relatively high and changing heat loads which can lead to the fastening being torn.
- Such cracks do not render the burner inoperable, but the gas distribution 5, 5 'required and as uniform as possible gas distribution for burning Such cracks or "leaky" locations interfere to a certain extent.
- the burner according to FIG. 3 is designed such that when two gas distributors 5, 5 'are arranged, the width B of the peripheral edge 8 of the inner gas distributor 5' is essentially the radial distance A ⁇ of both gas distributors 5, 5 'plus the Width B ⁇ of the peripheral edge 8 'of the outer gas distributor 5 is fastened to that of the inner one, the peripheral edge 8' being fastened to that of the inner gas distributor 5 'near the attachment area AB of the inner gas distributor 5' on the supporting plate 1.
- the outer gas distributor 5 is no longer in direct connection with the support plate 1, but is held by the peripheral edge of the inner gas distributor 5 ', which in turn is attached to the support plate 1 as far as possible from the burner surface.
- the freedom of movement of the peripheral edge of the outer or near the burner surface of the distributor 5 is increased to a sufficient extent, and it is no longer possible for the outer gas distributor 5 to be torn off at the peripheral edge.
- an additional carrier ring were arranged on the carrier, which would only be attached to the carrier on the inner circumference and on which the peripheral edges of the gas distributors would be fastened.
- a further insulation ring 20 is arranged under the support plate 1 in the region of its outer circumference between the latter and the heat insulation ring 15, this lying on the inside against the outer step embossment 7 of the support plate 1, and finally this is Support plate * 1 with its outer peripheral edge fixed by an externally placed tensioning and insulation ring 17 on the heat insulation ring 15.
- This training also contributes directly to the heat relief in this area, as gas can no longer escape and burn there.
- Such a ring 17 could, moreover, be easily fitted onto the atmospheric burner according to FIG. 4, which of course is to be arranged in the horizontal position, as shown, in the lower region of a boiler burner shaft.
