Abstract

The invention relates to a burner, in particular to a short-flame and large-diameter diesel burner. The short-flame and large-diameter diesel burner comprises a burner shell, an ignition rod and a diesel sprayer, wherein the ignition rod and the diesel sprayer are arranged in the burner shell. The burner shell is a spiral volute, an air inlet is formed in one side of an outer ring of the volute, an air outlet is formed in an inner ring of the volute, the direction of the air inlet is coincident with the tangent direction of the volute, the position of a diesel spraying nozzle of the diesel sprayer corresponds to the position of the air outlet of the volute, and the ignition position of the ignition rod is located above the diesel spraying nozzle and the air outlet. According to the short-flame and large-diameter diesel burner, the burner shell is designed into the volute, air enters the burner in the tangent direction of the volute, the air and diesel are mixed and burnt through centrifugal force, the structure is simple and attractive, the air and the atomized diesel can be more sufficiently mixed, losses of the atomized diesel can be reduced, the diameter of a hearth can be reduced, the size of a boiler can be reduced, and the burning cost can be reduced.

Description

A kind of short flame major diameter diesel fuel burner
Technical field
The present invention relates to a kind of burner, particularly relate to a kind of short flame major diameter diesel fuel burner.
Background technology
Diesel fuel burner is used for boiler combustion, the air of diesel fuel burner and the combustion flame shape of atomized diesel fuel mixing sufficient degree and diesel fuel burner and diameter can affect the integrally-built design of boiler, at present, common diesel fuel burner air and atomized diesel fuel all will by ignition again after a few step premix, this kind of structure makes its complicated integral structure, needs the boiler that design volume is larger; And mixing route is long, easily cause atomized diesel fuel to run off, combustion flame diameter is little, needs to design larger-diameter burner hearth; Also need to configure independent stable flame pan to stabilize the flame, thus raise the cost.
Summary of the invention
The present invention is in order to solve defect and the deficiency of the existence of above-mentioned prior art, provide a kind of simple and beautiful structure, air and atomized diesel fuel can be made to mix more abundant, reduce the loss of atomized diesel fuel, reduce furnace diameter, reduce boiler volume, utilize burner hearth flue gas to stabilize the flame, reduce the short flame major diameter diesel fuel burner of burning cost.
Technical scheme of the present invention: a kind of short flame major diameter diesel fuel burner, comprise burner shell and be arranged on fire rod, the fuel injector in burner shell, described burner shell is for being circinate spiral case, side, described spiral case outer ring is provided with air inlet, spiral case inner ring is provided with air outlet, described air inlet direction is tangentially consistent with spiral case, and the atomizer position of described fuel injector is corresponding with the air outlet position of spiral case, and the ignition location of described fire rod is positioned at the top of atomizer and air outlet.
Burner shell is designed to spiral case by the present invention, air along the tangential air intake of spiral case, by centrifugal force by air and atomized diesel fuel mixed combustion; Simple and beautiful structure, can make air and atomized diesel fuel mixing more fully, reduce the loss of atomized diesel fuel, reduce furnace diameter, reduce boiler volume, reduce burning cost.
Preferably, described fuel injector is connected with spiral case by a plate, and the spray bar of described fuel injector is located in connecting plate, and described connecting plate is fixed in the middle of bottom spiral case.
This kind of structure makes the connection of fuel injector and spiral case more solid and reliable, thus it is more reliable and more stable to make atomizer spray atomized diesel fuel.
Preferably, described spiral case top is provided with cover plate, and be provided with flame export in the middle of described cover plate, cover plate both sides are provided with refractory slab.
This kind of structure facilitates spiral case top can form heart-shaped major diameter flame, the service life arranging prolonging combustion device of refractory slab.
Burner shell is designed to spiral case by the present invention, air along the tangential air intake of spiral case, by centrifugal force by air and atomized diesel fuel mixed combustion; Simple and beautiful structure, can make air and atomized diesel fuel mixing more fully, reduce the loss of atomized diesel fuel, reduce furnace diameter, reduce boiler volume, reduce burning cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further detailed explanation, but be not limiting the scope of the invention.
As illustrated in fig. 1 and 2, a kind of short flame major diameter diesel fuel burner, comprise burner shell and be arranged on fire rod 2, the fuel injector 3 in burner shell, burner shell is for being circinate spiral case 1, side, spiral case 1 outer ring is provided with air inlet 5, and spiral case 1 inner ring is provided with air outlet, and air inlet 5 direction is tangential consistent with spiral case 1, atomizer 4 position of fuel injector 3 is corresponding with the air outlet position of spiral case 1, and the ignition location of fire rod 2 is positioned at the top of atomizer 4 and air outlet.Fuel injector 3 is connected with spiral case 1 by a plate 6, and the spray bar of fuel injector 3 is located in connecting plate 6, and connecting plate 6 is fixed in the middle of bottom spiral case 1.Spiral case 1 top is provided with cover plate 7, and be provided with flame 9 in the middle of cover plate 7 and export, cover plate 7 both sides are provided with refractory slab 8.
When the present invention works, air is along the tangential air intake of spiral case, and when air arrives spiral case air outlet, ejection atomized diesel fuel in atomizer, in spiral case, flow the centrifugal force that produces by air and atomized diesel fuel mixing by air, fire rod is by blender ignition combustion.
Because air goes out spiral case, there is larger centrifugal force, air is because the effect of centrifugal force is got rid of to surrounding, burned flame can be got rid of to surrounding, spiral case center has very large negative pressure, flame again can toward spiral case central motion, realize the backflow of spiral case inside smoke, reduce ignition temperature, reduce the discharge of nitrogen oxide; Flame gets rid of to surrounding and forms heart-shaped flame simultaneously, makes its flame diameter comparatively large, thus can reduce the size of flame export (burner hearth), thus reduce the volume of boiler, reduce boiler manufacture cost.
The course of work of fuel injector of the present invention is conventional, does not describe in detail in the present invention.
Burner shell is designed to spiral case by the present invention, air along the tangential air intake of spiral case, by centrifugal force by air and atomized diesel fuel mixed combustion; Simple and beautiful structure, can make air and atomized diesel fuel mixing more fully, reduce the loss of atomized diesel fuel, reduce furnace diameter, reduce boiler volume, reduce burning cost.
