Description
Technical field：The present invention relates to a kind of improved electric preheating, voluntarily gasification liquid fuel burner, particularly one kind are pre-
The electric preheating of mixing burning voluntarily gasification liquid fuel burner.
Background technology：I is preceding applying for Patent No.：201420457033.4, patent name is：Electric preheating gasifies
Liquid fuel burner, this kind of burner preferably resolves the gasification problem of fuel, realizes and is automatically brought into operation, relative to other stoves
Head, its larger thermal efficiency for improving burning.But through using after a while, it has been found that its Shortcomings：1st, gasification result
Difference, the reason is that the bore of the stainless steel tube for making fuel gasification pipe is below 8 millimeters, wall thickness also 0.5 millimeter with
On, result in the need for gasification liquid fuel receive heat transfer time it is relatively long so that gasification result is poor.2nd, gas sprays
Being carbonized and blocking easily occur in mouth, adversely affecting its combustion effect, because every kind of liquid fuel gasification has an optimal gasification temperature
Point is spent, once more than the temperature spot, being then easily carbonized, and does not have temperature control device in the burner, temperature often rises very
Height, the liquid fuel that liquid fuel enters after high-temperature fuel vapor lamp close to gasification tunnel inwall is gasificated into rapidly gas, hinders
The heat of fuel gasification inside pipe wall effectively conducts to gasification tunnel intermediate fuel, so as to cause not exclusively gasification, fuel gas
Change the liquid fuel in pipe as gaseous fuel sprays together；Meanwhile, contact high-temperature fuel gasification inside pipe wall gaseous fuel by
It is carbonized to high temperature, while the air nozzle aperture of burner is small, and is placed on burning office work, the high temperature of combustion chamber during work
The fuel gas in gas nozzle can be made to be carbonized and block fumarole.Air nozzle is aoxidized in itself during high temperature and also accelerated.3rd, noise
Greatly：Fuel gas mixing air-fuel is sprayed due to burner in combustion chamber built with hexagonal nozzle, during work by nozzle to burn, high pressure draught
Very big noise can be produced.4th, the thermal efficiency is relatively low, and this is that gasification result and combustion efficiency are not very good, so that the thermal efficiency
It is relatively low.
The content of the invention：It is an object of the invention to what is existed in use for above-mentioned electric preheating liquid fuel gasification furnace end
The deficiency that easily plug nozzle, gasification result are poor, burner fuel is easily carbonized, noise is big, the thermal efficiency is relatively low, and propose a kind of pre-
The electric preheating of mixing burning voluntarily gasification liquid fuel burner, it have be not easily blocked, gasification result is good, noise is small, the thermal efficiency
Higher advantage.
The purpose of the present invention can be realized by following technical proposals：A kind of electric preheating of premix combustion voluntarily gasified liquid
Fuel burner, including overall cast iron furnace head frame, fuel gasification pipe, electrothermal tube, combustion chamber, liquid fuel conduit, gaseous fuel are led
Pipe, ignitor, controller, it is characterised in that also including cooling tube, premixed device, gas diversion device, gas nozzle；Premixed device
The lower section of overall cast iron furnace head frame is fixed on, the lower end of premixed device is connected with gas nozzle, upper end and the flame water conservancy diversion of premixed device
Device is connected, and the lower part wall of premixed device is provided with the equally distributed passage of ring-type, and fuel gasification pipe horizontal endless is located at combustion chamber
Periphery, electrothermal tube be located at fuel gasification pipe periphery, cooling tube be located at electrothermal tube periphery, cooling tube, electrothermal tube, fuel gas
Change pipe to be fixed in the cavity of overall cast iron furnace head frame by pouring cast aluminium, gas nozzle passes through gaseous fuel conduit and fuel gasification
Pipe is connected, and liquid fuel conduit one end is connected with fuel gasification pipe, and the other end is connected with external fuel supply arrangement；Cooling tube one
End is connected with cooling medium, and another port is located at free surrounding space, and electrothermal tube, ignitor are electrically connected with the controller, combustion chamber bottom
The overall cast iron furnace head frame in portion is provided with passage.
To make combustion even, in premixed device upper end provided with the equally distributed vertical slot mouthful of ring-type.
To improve combustion efficiency and reduction noise, flame air deflector is inversed-cone shape, and it is cavity that it is internal.
To reach preferable gasification result, the temperature control of furnace end body is at 120-160 DEG C.
The diameter and wall thickness of fuel gasification pipe and cooling tube are 12-18mm, 0.2-0.3mm.
Effect of the invention is that：1st, gasification result is good, the reason is that being carried out for the parameter for making fuel gasification pipe
Change, i.e., be changed to diameter 12-18mm, wall thickness 0.2-0.3mm with more than wall thickness 0.5mm below original 8 millimeters of diameter, this
So that liquid fuel heating surface area is big, the heat time is short, so that gasification result is good；2nd, gas nozzle is not in carbonization and blocking
Phenomenon, combustion efficiency is good, because being provided with cooling tube in the present apparatus, cooling tube can be by the temperature control of furnace end body in fuel gas
Change optimum temperature required during pipe gasification liquid fuel, from without asking for occurring in the prior art in gasification link
Topic, in addition, the burning point of the present apparatus erects slit space greatly, entirely eliminated blocking existing at the vertical slot mouth of premixed device upper end
The appearance of elephant.4th, noise is small, reduces the pollution to environment, and this is in the present apparatus to be provided with flame air deflector, and it not only has
Effect of combustion efficiency is improved, and possesses preferable silencing function.4th, the thermal efficiency is greatly improved, and this is that the present apparatus not only exists
Gasification link and it is compared with the prior art and all significantly increases in the technique effect of burning link, so as to also just makes the thermal efficiency greatly
Improve.
