Description

[Detailed explanation of the invention] This invention is a multi-fuel burner.
Heater assemblies using
Concerning, more particularly, burners for heaters, heat exchangers and the like, of the type in which the burner elements are maintained at and operated from the side of the heating device rather than at the bottom; Regarding a directional combustion type burner. However, this is illustrative and not limiting.

Heretofore, in the manufacture of burners for heat exchangers, heater assemblies and the like, particularly dual fuel burners, the burners have been designed to be mounted directly to the bottom of the heater assembly. This method was the least troublesome because the flame was directed upwards and the state of such dual fuel burner technology was not advanced at the time.

No. 2,851,093, dated September 9, 1958. Patents entitled "dual fuel burners" are representative of standard bottom-mounted versions of these burners. In this patent, a central nozzle 48 sprays liquid fuel conically upwardly into and through a cylindrical shroud member 41 to combust the fuel within a cylindrical chamber of refractory material 12. There is.
In this system, air is introduced around the central fuel nozzle 48 by a dispenser 43, and the nozzle 48 and gun assembly 47 move them straight down to remove or replace them from the support cylinder 46. It is becoming more and more common. Other maintenance and adjustments must also be made from below, and the heater assembly is required to be mounted above ground level so that there is space below for its operation and maintenance. The burner of the above US patent represents a significant improvement over previous technology by producing a high combustion capacity in a small space due to the specific arrangement of the nozzles with specially constructed shrouds and refractory members. . An auxiliary gas tip 51 was also mounted from below the assembly to provide an independent air introduction and dispensing device.

Furthermore, the hot environment and dripping oil make maintenance of the equipment extremely unpleasant and difficult, and provide many opportunities for injury to workers.

Therefore, based on feedback from customers,
There is a need to provide a burner and burner assembly that maintains the efficiency of traditional burners while substantially eliminating the need to secure and operate the burner from below the heater assembly. Safety requirements have increased. This presented unique problems because of the critical geometry of the shroud, refractory material, and nozzle and their interaction.

The present invention is used in heater assemblies that maintain the high efficiency of known burners and allow removal of working parts, maintenance and operation of the burner from the side rather than from the bottom of the heater assembly. Provides a side-fired burner.

In order to prevent a complete modification of the fuel gun, which is a proven issue, the nozzle of the fuel gun has an upwardly oriented hole in the shape of a sector, unlike the previously described conical shape. It has been found that it is desirable for the shape of the shroud to match the shape of the fuel. The shroud or side plate of the present invention has a rectangular cross-sectional shape that matches the fan spray shape of the fuel gun nozzle.

Since the shroud is arranged in a vertical position and the gun nozzle is inserted horizontally, it is necessary that the nozzle be accurately positioned with respect to the shroud.
Nozzle positioning means are provided proximate the shroud to properly position the nozzle on the fuel gun assembly.

An air preparation means is located below the burner and supplies air around the nozzle and the auxiliary gas tip, said preparation means being remotely controlled on the side of the heater assembly.

The heater assembly is thus equipped with a plurality of side-firing burners, each burner being positioned proximate a refractory heat radiating wall to provide the necessary heat to the heater assembly.

Further, the novel nozzle shape and cooperating shroud of the present invention provide the ability to substantially completely burn fuel, which may be a lower grade fuel oil, mixed with steam for smokeless combustion.

That is, the present invention is a side-fired heater assembly in which a plurality of fuel burners can be mounted and operated from the side with respect to the assembly, and a burner-fired gun is similarly mounted on the assembly. It can be easily and quickly removed from the side. The air introduction and dispensing means for providing combustion air to the plurality of burners is fully operable from the side of the assembly, and furthermore, the heater assembly of the present invention has an internal wall constructed of refractory material for heat radiation. and a plurality of side firing burners are positioned with respect to the refractory wall to provide continuous radiant heat.

The shoulder 38 within the aperture 34 creates a swirling effect that provides for more complete combustion of the oil and gas mixture within the aperture and the swirling effect reduces the smoke and toxins emitted. bring. A fan-shaped flame 161 is then emitted from the burner onto the refractory side wall 2 of the heating device.
6, thereby heating the side wall 26 to a temperature such that heat is radiated toward and against the heat exchange tubes 24. Furthermore, the air introduced through the air conditioning device is transferred to the space 132, the hole 46, and the opening 7.
2 and around the nozzle 76.

When it is necessary to remove or maintain the oil/steam gun 74 or gas pipes 120, 122,
may be removed and maintained or replaced in a manner opposite to that described for their installation. A peep tube 156 has aperture 34 to ensure the presence of a flame.
Visual or electronic monitoring of the interior of the device is used throughout this operation.
