Definitions
- the present invention relates to a method pertaining to combustion, and to a burner. More specifically, the invention relates to a method and to a burner for the combustion of oxygen gas in respect of heating furnaces.
- the present invention satisfies this desideratum.
- the present invention relates to a method pertaining to the combustion of a fuel with an oxidant in a heating furnace, where the fuel and the oxidant are delivered to a burner head, and is characterized in that in a first method step fuel and oxydant are caused to be emitted from the burner head in the close proximity of one another so that the process of combustion will take place essentially close to and at a small distance out from the burner head until there is reached in the furnace space a temperature that exceeds the spontaneous combustion temperature of the fuel and in that in a second method step the fuel and the oxidant are then caused instead to be emitted from the burner head in mutually spaced relationship so that the process of combustion will take place essentially at a distance from the burner head corresponding to at least the diameter of the burner head and out from the burner.
- the invention also relates to a burner of the kind and with the general features set forth in claim 9.
- - Fig. 1 is a straight-on front view of a burner head according to a first embodiment
- Fig. 2 is a straight-on view of a burner head according to a second embodiment
- Fig. 3 is a diagrammatic illustration of a burner head and a flame as seen from one side when the burner is operated in a first manner
- - Fig. 4 is a diagrammatic illustration of a burner head and a flame as seen from one side when the burner is operated in a second manner.
- the inventive method thus pertains to the combustion of a fuel with an oxidant in a heating furnace, in which the fuel and the oxidant are delivered to a burner head.
- the burner head is mounted in a known matter in a furnace wall, so that the flame produced in the combustion process will extend into the furnace chamber.
- the invention is characterized in that the combustion process takes place in two steps, where the second step affords advantages over the known technology.
- a first method step fuel and oxidant are emitted from the burner head in close relationship with one another, so that the process of combustion will essentially take place close to and slightly spaced from the burner head.
- This method is known per se, in which the burner is designated "Oxy-fueP'-burner.
- the burner is operated until a temperature exceeding the spontaneous combustion temperature of the fuel is reached in the furnace chamber.
- the second step of the combustion process may conveniently be initiated when the furnace temperature is above roughly 750 degrees C.
- this second method step is carried out when this temperature or a still higher temperature has been reached.
- the fuel and the oxidant are caused instead to be emitted from the burner head at a distance from each other, so that combustion will take place generally at a distance from the burner head that corresponds at least to the diameter of the burner head and out from the burner.
- the fuel is caused to be emitted from a nozzle 2 in the burner head 1 and the oxidant is caused to be emitted from outlet openings 3 placed concentrically around the nozzle 2; see figure 1. It is also preferred that in the second method step, the fuel is caused to be emitted from a nozzle 2 in a burner head 1 and that the oxidant is emitted from outlet openings 4,5 located on one side of and at a distance from said nozzle 2; see figure 1.
- the outlet openings 4, 5 are comprised of Laval nozzles or venturi-nozzles.
- the opening 6 functions to monitor the flame.
- the outlet openings 4, 5 are spaced from the fuel nozzle 2 by a distance that exceeds half the diameter of the burner head.
- the burner thus permits two different modus operandi, partly as a typical oxy-fuel burner and partly as a burner which functions to produce a flame of essentially lower maximum temperature.
- This lower flame temperature is adapted to lie beneath the temperature at which the formation of NOx is limited by the reaction kinetics, this temperature being about 1550 degrees C.
- the concept of the invention resides in lowering the oxygen content in the combustion zone, despite the oxidant having an oxygen content of more than 80%, by virtue of separation, high pressure and an optimized nozzle placement. This is achieved with a nozzle configuration that affords a high subpressure on those surfaces of the nozzle that lack medium-emitting nozzles. As a result of the subpressure, flue gases are sucked in from the furnace atmosphere and quickly mix with the out flowing media and therewith create turbulence.
- the mixing medium i.e. the furnace atmosphere, typically has an oxygen content of 0.5-10%.
- the remainder of the gas is comprised of CO 2 and H 2 O and N 2 in varying mixtures.
- the nozzles can be directed conveniently straight forward, i.e. they need not be directed away from or towards each other, although they may be angled towards or away from the longitudinal axis of the burner head.
- the oxydant is gaseous and is given an oxygen concentration of 85 % or higher.
- the oxidant is delivered to the burner at a pressure of at least 2 bar overpressure. Because the flame temperature is lower and the mixture of gas in the furnace volume is greater than in the case of oxy-fuel-combustion, the formation of NOx is minimized while the temperature differences in the furnace space are dramatically lowered at the same time.
- a burner nozzle according to the present invention is no larges than a known burner head for oxy-fuel-combustion.
- the burner nozzle has a diameter of about 70mm.
- the compact method enables the invention to be applied in equipment already possessed by the user. Moreover, the equipment can be placed in a small water-cooled protective casing for application at very high process temperatures.
- the aforesaid advantages are achieved in accordance with the invention with a selected fuel, solid fuel, gaseous fuel or liquid fuel.
- the inventive arrangement can replace existing combustion systems in principal without re-constructing the furnace equipment used for the process.
- the burner head shown in figure 1 is intended for oil as fuel.
- FIG. 2 shows a burner head 10 for natural gas as fuel.
- the nozzle 11 is intended for natural gas.
- the outlet openings 12, 13, 14 are intended for the oxidant.
- the opening 15 is intended for monitoring the flame and the opening 16 is intended for a pilot flame.
- the oxidant is injected into the combustion space via one or more nozzles in the form of Laval nozzles or venturi nozzles.
- the oxidant will preferably be under an overpressure of at least 2 bar. The higher the pressure, the better the efficacy of the invention. A preferred pressure for normal applications is 4-5 bar.
- the fuel is injected via conventional nozzles at the pressure available.
- the design of the burner head can be varied.
- the burner head may include more oxidant outlet openings than those shown.
- the placement of the fuel nozzle may be different to that shown in the drawings.
