ES2637192T3 - Burner and combustion device comprising said burner - Google Patents

Abstract

A burner (1) for producing a combustion device (100), wherein said burner (1) comprises: - a main body comprising an operating cavity (11) of substantially cylindrical shape extending along a direction axial (X) having the same diametrical dimension, said operating cavity being open on at least one first side and closed on the other side by a casing wall (12); - first feeding means for introducing a flow of a first reagent into said operating cavity (11) in an admission position for said first reagent (P1), said first feeding means (20) configuring a tangential admission of said first reagent in said operating cavity (11); - second feeding means for introducing a flow of a second reagent into said operating cavity (11) at an admission position (P2) of said second flow, said second feeding means introducing said flow of second reagent according to a direction substantially parallel to said axial direction (X) along which said operating cavity (11) extends, said second feeding means (30) comprises a lance (30) extending through said casing wall (12) of said main body, said lance (30) comprising a portion (30B) outside said main body and a portion (30A) inside said main body and coaxial with said operating cavity (11), and combustion ignition means disposed inside of said lance in which said operating cavity (11) comprises a first portion (11A) between said admission position (P1) of said first reagent and said admission position (P2) of said second reagent, defined said first portion being a chamber for stabilizing the movement of said first reagent, said operating cavity (11) comprising a second portion (11B) defining a combustion chamber downstream of said admission position (P2) of said second reagent.

previously. The tubular element 10 of the burner 1 is located at least partially inside the carcass liner 50 through the first wall 51 so that the primary combustion chamber 11B is substantially coaxial with the casing 50 of the casing or with the chamber 18 of secondary combustion As can be seen, the tubular element 10 is distanced from the second wall 52 so that the products of

5 combustion supplied from the primary combustion chamber 11A can be released into the secondary combustion chamber 18.

[0036] The first wall 51 of the housing liner 50 comprises a discharge opening 55 for discharging products derived from the second combustion. In particular, in the illustrated solution, the discharge opening 55 is coaxial with the housing liner 50 or with the tubular element 10 of the burner 1. The combustion device 5 can advantageously comprise a transport element 58 for transporting the products of The second combustion. In the illustrated case, the transport element 58 comprises a discharge outlet 59 that can be connected, through a flange element 59B, to an evacuation conduit, not shown in the figures. According to the requirements, these products can be transported to a combustion stage

15 additional combustion device 5 or within another device. Alternatively, combustion products could be released directly into the atmosphere if their temperature is sufficiently low.

[0037] Figures 10 and 11 refer to a second embodiment of a combustion device 5 according to the position that differs from the previous one by using a liquid fuel burner 1. By comparison of

20 Figures 8 and 9, it can be understood that in the two embodiments of the combustion device 5 its structure is substantially identical with advantages evident from the point of view of manufacturing costs. Naturally, the dimensions of the two devices are set according to the type of fuel to be used and the required operating conditions.

[0038] The technical solutions adopted for the burner allow the objectives and objects to be fully achieved. In particular, the burner according to the invention has a high functional versatility, which makes it suitable for use in different applications. In particular, it can be used for partial or total combustion or, alternatively, as a heating element for fluids that transport heat or solid masses. The burner structure according to the invention allows it to be used to produce combustion devices

30 multi-stage, particularly compact and efficient, with extremely limited manufacturing costs.

[0039] The burner and the combustion device thus conceived are susceptible to numerous modifications and variants, all of them within the scope of the inventive concept; In addition all the details can be replaced by other technically equivalent details.

[0040] In practice, the materials used and the contingent dimensions and shapes may be any, in accordance with the requirements and prior art.
