Abstract

The utility model relates to a high-viscosity fuel oil burner with high heat load. The oil and the steam are connected with a mixing and atomizing chamber by the tail end of a tubular oil gun through two pipelines. The utility model is characterized in that the front end of a fuel oil conveying pipe is fixedly connected with a mixer; the end surface of the mixer is uniformly distributed with oil holes and steam holes; the outer layer of the fuel oil conveying pipe is fixedly connected with an atomizing steam conveying pipe through the tail end of a connecting sleeve; the front end of the connecting sleeve is fixedly connected with a spray nozzle of a burning oil gun. The utility model not only can burn the high-viscosity oil products and burn large fuel oil quantity, but also can greatly improve the burning temperature and improve the heat efficiency. As the burning is sufficient and the temperature is uniform, the generation of CO, SO3, NOx and carbon quantity is suppressed, which is favorable for protecting the environment. The utility model obviously reduces the electric power consumption of the blower for blowing air, and has an obvious energy-saving effect.

Description

High heat load heavy oil gas turbine liquid-fuel burner

The utility model belongs to the liquid-fuel burner technical field, relates in particular to a kind of very high residual oil of the big high heat load burning of amount of fuel viscosity, liquid burner of greasy filth of being suitable for.

In burner, can make the very high residual oil of viscosity, greasy filth fuel as burning usefulness, it can fully be burnt, prerequisite is that it can fully be atomized, the atomizing olesome should be tiny as much as possible, create favorable conditions for it can well mix equably with combustion air, it is fully burnt.Up to now, many people are the refinement liquid fuel how, especially number of research projects has been done in this type of liquid fuel atomization particulate aspect of the very high residual oil of refinement viscosity, designed the liquid burner of diversified burning residual oil, but its measure of adopting is nothing but at the discharge pressure that improves fuel oil or requires to improve its oily temperature simultaneously, purpose is the viscosity for the pressure function of utilizing fuel oil and reduction residual oil, its atomizing is attenuated burns, but its combustion efficiency is all not ideal, the burner of the thermic load that has low (amount of fuel is few) also has the atomizing of employing steam, but it requires fuel flow pressure and temperature still not low, because the atomizing particle fineness is all not ideal, efficiency of combustion is high and because oil pressure is higher, brings many hidden dangers to burner operation and operator.

The Chinese patent IL97208001.5 number " multistage atomizing that announce the 6 days February in 1999 of our company, the omnipotent oil gun of storing injection internal-mixing " solved the problem of above-mentioned existence well, owing to used multistage atomizing, many stacks, the storing injection technology, successfully solved under the not high situation of fuel pressure, make the high fuel residual oil of viscosity, the peaceful average diameter of greasy filth atomizing oil droplet is about 30mm, reach unprecedented degree of refinement, fuel oil is burnt fully, improved efficiency of combustion, but this type of waste fuel oil gun for the high heat load requirement, because the amount of fuel of heavy fuel residual oil increases considerably, and often reaches per hour several tons more than according to the needs amount of fuel.The sectional area of the single nozzle opening of blender by former burner oil gun will increase with corresponding multiple like this, certainly will form one swiftly flowing big oil column, will be atomized into big so single oil column trickle mist of oil in such cases drips and brings very big difficulty, cause the bad consequence of atomizing, thereby directly influence the combustion position improvement and reduce efficiency of combustion, easily form harmful substances such as CO, SO3, NOx and generate, pollute environment.

The purpose of this utility model is in order to remedy above-mentioned technical deficiency part at big oil mass combustion of high viscosity oil product, a kind of reliable combustion of high viscosity residual oil or greasy filth and the operation of energy high heat load are provided, simultaneously can obtain sufficient combustion, thermal efficiency height, pollutant CO, SO3 in the flue gas, the novel burner that NOx is few.

The technical scheme that realizes the utility model purpose is such, at tubulose oil gun tail end, divide two pipelines that oil, vapour are connected to the mixed aerosol chamber, it is characterized in that the front end uniform oilhole of an affixed end face of fuel feed pipe and the blender of steam vent, the skin of fuel feed pipe is by the affixed atomizing steam carrier pipe in rear end of adapter sleeve, the affixed burning oil gun of front end nozzle.

The utility model not only can burn with big amount of fuel by the combustion of high viscosity oil product; and can increase substantially ignition temperature; improve the thermal efficiency; because sufficient combustion; temperature is even, so suppressed the generation of CO, SO3, NOx and carbon black, helps environmental protection; reduce simultaneously the air blast power consumption of air-supply significantly, had remarkable energy saving effect.

Embodiment of the present utility model is provided by the following drawings:

Accompanying drawing 1 is an assembling front view

Accompanying drawing 2 is that Figure 1A is to view

Accompanying drawing 3 is blender front views

Accompanying drawing 4 is Fig. 3 side views

The concrete structure and the course of work of the utility model embodiment are described below with reference to the accompanying drawings:

By accompanying drawing 1 as can be known, by tubulose oil gun tail end, divide two pipelines that oil, vapour are connected to the mixed aerosol chamber, be characterized in the front end uniform oilhole of an affixed end face of fuel feed pipe 4 and the blender 2 of steam vent, the skin of fuel feed pipe 4 is by the affixed atomizing steam carrier pipe 5 in rear end of adapter sleeve 3, the affixed burning oil gun of front end nozzle 1.

By accompanying drawing 3,4 as can be known, an end of blender is that screw thread is connected with fuel feed pipe 4, and the other end is spill, uniform oilhole on concave bottom end face circumference, oilhole tiltedly bores with axis of spindle a β angle, and uniform steam vent on the circumference of concave bottom side, steam vent also tiltedly bore with axis of spindle a α angle.The hemisphere nose circle perimeter surface of burner oil gun nozzle 1 is evenly equipped with spray-hole, and the center line of spray-hole and oil gun center line have a α angle.

Dynamic duty process of the present utility model: the high viscosity residual oil of big flow or greasy filth in fuel oil carrier pipe 4 with certain temperature flow at high speed, a plurality of nozzle openings are divided into multiply and are sprayed into mixing chamber K (accompanying drawing 1 by speedup in its special blender 2, K in 2) oozed mixed with multiply number more strongly by high-temperature vapour atomizing steam carrier pipe 5 and that be pressurized speedup in, in fact, atomizing steam oozes mixed per share tiny fuel oil column by (reaching several strands sometimes) more than one, so, after being cut apart, fuel oil evenly obtains effective mixed aerosol, make the high viscosity oil droplet be atomized into superfine little oil droplet effectively through storing injection then from nozzle 1 ejection at a high speed, promote and very mixed combustion equably of air, thereby obtained abundant combustion efficiency, use present technique to need not a lot of superfluous combustion airs, excess air coefficient significantly descends, and often only needs about 1.08.
