Abstract

The utility model discloses an oil tank of self-preheating evaporating oil-stove, witch is a deice ensuring the normal proceed of the start-up preheating of the evaporating oil-stove. The utility model enlarges the fuel oil range of the evaporating oil-stove and the gasoline is avoided as the fuel of the evaporating oil-stove. The safe ordinary diesel oil of higher ignition point is the main fuel of the evaporating oil-stove. The technical character is that a small tank (namely sub-tank) is arranged in the fuel tank of the evaporating oil-stove. The sub-tank is communicated with the upper part space of the liquid level of the fuel tank. The pressure of start-up spraying burning is formed through once injection molding.

Description

Oil tank of self-preheating evaporating oil-stove

The utility model relates to a kind of self-preheating vaporization oil stove that guarantees and starts a kind of device that preheating is normally carried out.

Vaporization oil stove need start preheating before igniting is used, make the fuel oil vaporization of being heated in the economizer bank of stove, and then with air mixed combustion.The mode that startup preheating is at present generally adopted is: come pre-heating oil with external thermal source (without the fuel of stove own, but being heated by resistive device, gas and oil or alcohol).The problem that this mode exists is: (1) electrical heating power consumption big (electric heater capacity is two, three hectowatts) also makes the use of stove be had a power failure or does not have electric influence, (2) do trouble comparatively with gas and oil or alcohol heating behaviour and (contain the below that a certain amount of gas and oil or alcohol place economizer bank with a container, light the heating economizer bank) fuel of general stove is gas and oil, when the fuel of stove is kerosene or light diesel fuel, so be subjected to the very little startup of the restriction volume preheating behaviour of furnace construction to do and to repeat several times with oily container because of containing the startup preheating.(3) be to be in that to start preheating time a little less than the spontaneous firing state flame longer because of gas and oil or alcohol besides.What (4) especially be worth to propose is, the fuel oil that generally adopts the stove of this mode preheating to use all is gas and oil more than 90 percent, starts at every turn that preheating behaviour does and is to be under the exposed situation at gas and oil or alcohol to carry out, so very dangerous.

In order to address these problems, nearly one, the self-preheating vaporization oil stove appearred in 2 years, promptly the startup preheating method on the gas lamp is used on the vaporization oil stove, one atomizer (also claiming flame projector) is installed on stove, the fuel that the startup preheating is used is the fuel oil of stove itself, fuel oil in the stove fuel tank and air form vaporific spray combustion then through atomizer economizer bank are started heating under certain air pressure, because of fuel oil is an atomizing spray combustion flame than strong many of the spontaneous firing of oil, also just shortened preheating time so start, behaviour does only needs igniting breakdown atomizer just passable, so simply save trouble; The atomizer spray combustion is very high to the requirement of the kind of furnace fuel oil and quality though this startup preheating goes a step further earlier, not only requiring the oil cleaning but also requiring fuel oil is gas and oil, kerosene or height light diesel fuel, and can not form normal spray combustion to the high ordinary diesel oil atomizer of the burning-point more than No. zero, this is restricted with regard to the scope of application that makes vaporization oil stove.

The purpose of this utility model is to make the startup preheating of vaporization oil stove not be subjected to the kind and the quality influence of vaporization oil stove fuel oil, allows the fuel oil of vaporization oil stove be applicable to the widely used ordinary diesel oil of people.

The purpose of this utility model is achieved in that a little fuel tank (seed oil case) is set in the furnace fuel fuel tank, starts required high-quality oil plant (normally Qing Jie kerosene) the little fuel tank liquid level of preheating and the space on large tank liquid level top is a UNICOM in order to shove charge.

The utility model is provided with a little fuel tank (seed oil case) the startup preheating is separated with the fuel oil of oil and stove because be in the tire of large tank,, the startup preheating of little fuel tank just can realize that ordinary diesel oil just can be as the fuel oil of stove like this as long as guaranteeing with oil that atomizer normally sprays to fire to various preheating of fuel oils; From the fire safety aspect, ordinary diesel oil has been Duoed than gas and oil, light bavin safety; Factor fuel tank is in large tank again, and the output of stove fuel oil burning needs stove gas injection pressurising, so only need give large tank pressurising seed oil case liquid level with regard to pressurized, atomizer has just had oil atomization ejection pressure; So factor fuel tank is not again that not to be subjected to air pressure can be as thin as a wafer container such as iron tin can for the seed oil case of sealing in the large tank tire besides.

Accompanying drawing is the device profile according to the self-preheating oil gasification furnace seed oil box technology that the utility model proposes.

Below in conjunction with description of drawings according to the device details that the utility model proposes and the course of work of stove.

This device comprises: seed oil case 1, seed oil case fixed mount 7, startup preheating petroleum pipeline 6.

The course of work of stove: be respectively charged into fuel oil and pre-deep fat (the two ratio 1:12) and inflate then.At first breakdown atomizer 2 is lighted a fire simultaneously and is made atomizer form the spray combustion, then opening filling valve 5 makes fuel oil enter economizer bank 3, opening needle-valve 4 vaporific fuel oils when fuel oil is heated vaporization in economizer bank just just burns behind air intake duct, oil gas mixing chamber from the nozzle ejection of economizer bank, at this moment atomizer 2 finishes and starts the preheating purpose and just can cut out, also heat economizer bank in the time of with after-combustion and made fuel oil constantly be preheated gasification, so just formed the circulating combustion of stove.

Claims (1)

1, self-preheating oil gasification furnace seed oil box technology is characterized as:

A, in the fuel tank tire, be provided for the seed oil case that stove starts preheating;

B, fuel tank are communicated with seed oil case ullage space;

C, the required pressure of stove startup spray combustion preheating are once annotated to press by fuel tank and are formed.
