Abstract
The utility model discloses a reinforced nozzle of a burner. The reinforced nozzle of the burner comprises a nozzle body. At least one protective layer is arranged on the inner wall of the nozzle body. A reinforced rib is fixedly connected on the inner wall of the nozzle body and arranged inside the protective layer. The protective layer can protect the inner wall of the nozzle body from being eroded by high-temperature air flow and abraded by tar in the process of delivering high temperature flames, meanwhile the reinforced rib fixedly connected on the inner wall of the nozzle body can strengthen the attachment force of the protective layer and the inner wall of the nozzle body and prevents the protective layer from peeling off from the inner wall of the nozzle body. Therefore, the service life of the reinforced nozzle of the burner is significantly prolonged and the maintenance cost of the nozzle body is reduced.
Description
Technical field
The utility model relates to a kind of combustor nozzle, particularly a kind of reinforced combustor nozzle.
Background technology
As everyone knows; Nozzle plays the channeling of the combustor thermal-flame being sent into firing equipment, and common nozzle is generally made with heat resisting steel, but washes away because of its inwall receives high temperature gas flow for a long time; Especially receive the etch of tar; Often use just distortion about 3 months, damage, need heavily renew nozzle, maintenance cost is big.
The utility model content
In order to address the above problem, the purpose of the utility model is to provide a kind of simple in structure, corrosion-resistant and nozzle that the time in service life is long.
The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of reinforced combustor nozzle; Comprise nozzle; The inwall of nozzle is provided with the protective layer that quantity is no less than one deck, and the reinforcement that is fixedly connected on the nozzle inwall is contained in protective layer inside, and above-mentioned protective layer can protect the nozzle inwall in transmitting the process of thermal-flame, not receive high temperature gas flow to wash away the abrasion with tar; Being fixedly connected on reinforcement on the nozzle inwall simultaneously can the enhance protection layer and the adherence of nozzle inwall, avoids protective layer to come off from the nozzle inwall easily.
As the improvement of technique scheme, described nozzle is made up of loose joint nozzle that is mounted on combustor crater place and the nozzle main body that is arranged on loose joint nozzle left side.
Improvement as technique scheme; The right-hand member of described nozzle main body is provided with the tangent line air inlet; The tangent line air inlet is connected with ventilation shaft on being arranged on nozzle main body outer wall surface; Above-mentioned tangent line air inlet can import the wind in the external world in the ventilation shaft, and nozzle is cooled off, the protection nozzle.
As the improvement of technique scheme, the height of described reinforcement is less than or equal to the thickness of protective layer, and the height of above-mentioned reinforcement is less than or equal to the thickness of protective layer, has made things convenient for the ramming of protective layer, helps to practice thrift labour cost.
As the improvement of technique scheme, the number of plies of described protective layer is that one deck, thickness are 25mm, and the number of plies of above-mentioned protective layer is elected one deck as, thickness is 25mm, makes the easy to make of nozzle, practices thrift cost.
Improvement as technique scheme; Described reinforcement is to be fixedly welded on the reinforcing bar on the nozzle inwall or is that the protective layer that can make that is fixedly connected on the nozzle inwall is attached to the protrusion on the nozzle inwall better; Above-mentioned reinforcement is elected reinforcing bar as; The fixedly welded and installed that had both made things convenient for reinforcement can make the adhesion of protective layer and nozzle inwall better again at the nozzle inwall, prevents that protective layer from coming off from the nozzle inwall easily easily.
The beneficial effect of the utility model is: set up the protective layer that one deck is processed with high-temperature refractory A600 aluminate high temperature resistant cement and bauxites aggregate because the utility model is employed on the inwall of nozzle; Can avoid the nozzle base metal to receive high temperature gas flow washes away with the erosion of tar and causes nozzle easy deformation, damage; Set up in the inside of protective layer simultaneously to be fixedly connected and be installed in the reinforcement on the nozzle inwall; Can the enhance protection layer and the adhesion of nozzle inwall, prevent that protective layer from coming off from the nozzle inwall easily, therefore; Can protect nozzle well, strengthen the service life of nozzle.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the right flank view of the nozzle main body of the utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2; A kind of reinforced combustor nozzle; At first process loose joint nozzle 10 and nozzle main body 11 with steel; Be installed in the installation through holes 100 of combustor burner sheet then respectively in two fixed connections of upper and lower surface processing of loose joint nozzle 10 right-hand members; Process the installation through holes of advancing jet-burner 110 that two fixed connections are installed in firing equipment in the upper and lower surface of the right-hand member of nozzle main body 11 respectively at last, above-mentioned loose joint nozzle 10 and nozzle main body 11 constitute the nozzle 1 of the utility model.
Further; Respectively on welded and installed on the inwall of loose joint nozzle 10 and nozzle main body 11 six reinforcing bars as the reinforcement 3 of the utility model; Reinforcement 3 is evenly distributed on the inwall of loose joint nozzle 10 and nozzle main body 11 and reinforcement 3 is no more than 25mm at the height of loose joint nozzle 10 and the inwall raising of nozzle main body 11; The quantity of above-mentioned reinforcing bar is no less than one; Here preferentially elect six as, described reinforcement 3 can preferentially be elected reinforcing bar here as for being fixedly welded on the protrusion on loose joint nozzle 10 and nozzle main body 11 inwalls.
Further again, A600 aluminate high temperature resistant cement and bauxites aggregate is even by weight the mixed of 1:2, cooperate special-purpose nozzle inwall ramming punching block, ramming one layer thickness is the protective layer 2 of 25mm on the inwall of loose joint nozzle 10 and nozzle main body 11 respectively.
Further; On the upper and lower surface of nozzle main body 11, process two central axis ventilation shafts 40 in the same way with the nozzle main body respectively; And on the upper and lower surface of nozzle main body 11 right-hand members, process two tangent line air inlets 4 respectively, described two tangent line air inlets 4 are connected with its ventilation shaft of going up in the horizontal direction 40 respectively.
Reinforced combustor nozzle in the course of the work; The internal channel that the thermal-flame that produces in the combustor passes reinforced combustor nozzle gets in the firing equipment, and in this process, the protective layer of ramming on reinforced nozzle inwall can be avoided reinforced nozzle base metal to receive high temperature gas flow washing away the erosion with tar; Make the nozzle life-span improve widely; And after protective layer peels off, the new protective layer of ramming again, thus maintenance cost saved widely.
The above is merely the preferential embodiment of the utility model, as long as realize that with basic identical means the technical scheme of the utility model purpose all belongs within the protection domain of the utility model.
