In view of the above, the present invention provides a burner fire grate, a burner and a water heater, in the present application, the burner is mainly used in a gas water heater, and fig. 1 to 4 are an embodiment of the burner fire grate provided by the present invention.
Referring to fig. 1 to 2, in the present embodiment, the burner includes a burner fire row 100, the burner fire row 100 includes at least two layers of fire hole plates 1, the fire hole plates 1 are provided with a plurality of fire holes 2 arranged at intervals, in two adjacent layers of the fire hole plates 1, one fire hole plate 1 at least partially covers the other fire hole plate 1, and the fire holes 2 between two adjacent layers of the fire hole plates 1 are communicated with each other. The fixing manner of the burner fire row 100 in the burner and other structures of the burner can adopt the existing structures, so the details are not described herein.
In the technical scheme provided by the invention, the fire hole plates 1 of the burner are provided with at least two layers, and the fire holes 2 on the two adjacent layers of fire hole plates 1 are communicated, so that the tempering depth of flame can be deepened, the preheating capability of the flame on unburned mixed gas is reduced, and the prevention of tempering is facilitated.
In an embodiment of the present application, the areas covered by two adjacent layers of the fire hole plates 1 are arranged at intervals, so as to form an interval between the two layers of the fire hole plates 1, so as to form a channel for flame or mixed gas to pass through.
Further, be adjacent two-layerly that the interval set up fire hole 2 between the fire hole board 1 is the dislocation set to when taking place the tempering, from the upper strata the flame of 1 refluences of fire hole board passes through the lower floor can effectively obstruct during the fire hole board 1 to inside flame backward flow to the combustor leads to the combustor scaling loss. The fire holes 2 on the fire hole plates 1 of two adjacent layers can be completely staggered or partially staggered, so that the holes of the fire holes 2 are reduced, and tempering is effectively prevented.
In another embodiment of this application, adjacent two-layer the region that fire orifice plate 1 covered mutually is the laminating setting, one fire orifice 2 and another of fire orifice plate 1 fire orifice 2 just to setting up, is promptly two-layer when fire orifice plate 1 is equipped with the region of fire orifice 2 and is the laminating setting, each layer fire orifice 2 on the fire orifice plate 1 all is the one-to-one setting to block up fire orifice 2, and multilayer fire orifice plate 1 folds and establishes together, makes the hole of tempering increase deeply, makes the ability decline of preheating of the mixed gas of not burning of flame in to the combustor, is favorable to preventing the tempering.
Obviously, above-mentioned two kinds of embodiments also can be constructed and implement together, adjacent two-layer promptly a part of fire orifice plate 1 is the interval setting, and another part is the laminating setting, and fire hole 2 on the two-layer fire orifice plate 1 that the interval set up is the dislocation set, and fire hole 2 on the two-layer fire orifice plate 1 of the part of laminating mutually is just to setting up to rationally setting up arranging of fire hole 2 according to the inner structure of different combustors, the effect is better.
In an embodiment of this application, adjacent two-layer the shape of fire hole 2 between the fire hole board 1 is all the same, so that 2 accessible one-time stamping forming of fire hole on the fire hole board 1, the processing of being convenient for to practice thrift the cost.
In another embodiment of this application, the shape of the fire hole 2 between the fire hole plate 1 of two adjacent layers can also be set up to be the difference setting, and it means that there is a difference in size, form or structure etc. of each fire hole 2 to be the difference, every layer the fire hole 2 on the fire hole plate 1 can be partly different, also can be totally different, and the fire hole 2 between each layer can also be set up to be different, in this application the fire hole 2 shape does not make concrete restriction to the setting mode that can supply the gas to pass through all shall belong to the protection scope of this application.
In an embodiment of the present application, referring to fig. 3 and 4, in one fire hole plate 1, a central line of each fire hole 2 forms an included angle with a plane where the fire holes 2 are located, the fire holes 2 on each fire hole plate 1 are arranged to form inclined holes penetrating through the fire hole plate 1, the arrangement of the inclined holes is equivalent to extending a tempering channel, and the multiple fire hole plates 1 are stacked together, so that the tempering channel is zigzag, thereby facilitating to prevent tempering.
Specifically, in the present application, referring to fig. 2, the fire hole plate 1 includes a main body plate 11 and an installation plate 12 bent and extended from a side edge of the main body plate 11, the fire holes 2 are arranged on the main body plate 11, in two adjacent layers of the fire hole plate 1, one main body plate 11 is arranged to cover the other main body plate 11, and one installation plate 12 is arranged to cover the other installation plate 12. The specific structure of the mounting plate 12 is not specifically limited herein, so that the arrangement of the burner fire row 100 on the burner should fall within the scope of the present application. The adjacent two layers of the fire hole plates 1 can be connected through welding and can also be fixed relatively in a detachable mode, so that the multiple layers of the fire hole plates 1 form a whole, and the fire hole plates are convenient to install into the combustor for positioning.
Further, adjacent two-layer in the fire orifice plate 1, one main part board 11 is equipped with towards another the arch that main part board 11's opposite direction set up to adjacent two-layer form the interval between the main part board 11 of fire orifice plate 1, one fire orifice 2 of fire orifice plate 1 is located protruding, another fire orifice 2 of fire orifice plate 1 locate with protruding just right region, and adjacent two-layer fire orifice 2 between the main part board 11 is the dislocation set, is equipped with the arch fire orifice plate 1 and another other regions of fire orifice plate 1 all are the laminating setting, so that the structure that combustor fire was arranged 100 is more compact, just the arch can be provided with many places, in order to according to the type or the load demand of combustor set up.
The burner fire row 100 in the application is used for a burner, and can make the minimum load of the burner smaller, so that the regulation ratio of the burner is improved, and particularly when the burner fire row is applied to a water heater, the minimum load is reduced, the minimum temperature rise is smaller, and the problem of water scalding in summer can be avoided.
