Abstract

The utility model discloses a fuel oil gasifying stove with a self feedback function. Liquid oil fuel gasifying pipes of the utility model are filled with hot cracking catalyst, and a feedback loop of the utility model feeds partial gasified and hot cracked oil gas back to an oil fuel storing tank for preheating the liquid oil fuel gasifying pipes in next ignition. The utility model solves the difficulty of the ignition of gasifying stoves and increases the combustion efficiency of fuels.

Description

Oil-gasifying stove with self-feed function

The utility model relates to a kind of use kerosene, diesel oil, heavy oil and other liquid fuel, has to make part of fuel cracking and part oil gas from presenting the fuel-oil gasification of function.

Gasification furnace is to make fuel oil through placing heated liquid oil plant vapor lamp on the stone or metal plate for standing a stove on as a precaution against fire, and mix with air the gasification back, burns on stone or metal plate for standing a stove on as a precaution against fire.But this gasification furnace has such problem, need use external heat source that liquid oil plant vapor lamp is heated to when igniting and can make the liquid oil plant ebullition, gasification of flowing through wherein, just can change normal operation over to, and the oil plant boiling point is high more, and is difficult more during igniting.

For making igniting become easier, the someone uses low boiling oil plant such as gasoline as fuel, but this can make the fuel cost expense improve.

The purpose of this utility model is that will to provide a kind of be the gasification furnace of fuel with kerosene, diesel oil, heavy oil and other flammable liquids, has the part of making oil plant thermal cracking and oil gas from presenting function, has both solved ignition difficulties, also improves efficiency of combustion.

The purpose of this utility model is achieved in that in liquid oil plant vapor lamp loads thermal cracking catalyst, part is a low boiling oil gas by pyrolysis when the heated liquid oil plant of oil passing vapor lamp, the hot cracked oil gas of a part returns the oil plant basin and is stored in liquid oil plant upper space, uses a part to be stored in the interior oil gas of basin during igniting.

The utility model is to fill zeolite to make thermal cracking catalyst in liquid oil plant vapor lamp, because fuel oil is cracked into low boiling oil gas through liquid oil plant vapor lamp portion of hot, has improved efficiency of combustion; Increase by one section feedback pipeline that constant pressure valve is housed, simple in structure, be pressure automatic control because constant pressure valve opens and closes, can realize automatically that the hot cracked oil gas of part feeds back to the oil plant basin; Owing to use the part oil gas combustion preheater liquid oil plant vapor lamp of storing in the oil plant basin, this gasification furnace igniting become as using cylinder for liquefied gas convenient.

Concrete structure of the present utility model is provided by following examples and accompanying drawing.

Describe in detail according to gasification furnace structure and the working condition that the utility model proposes below in conjunction with Fig. 1.

This gasification furnace comprises body of heater 1, fill zeolite in putting on it and make the liquid oil plant vapor lamp 2 of thermal cracking catalyst, the liquid oils materials flow is through vapor lamp 2 gasifications, a part is thermally cracked to low boiling oil gas, and partial gasification and low boiling oil gas that be cracked into returns oil plant basin 5 through constant pressure valve 4 at threeway 3 punishment stream; On stone or metal plate for standing a stove on as a precaution against fire, burn after needle valve 6 sprays into body of heater 1 and air mixes at threeway 3 punishment stream another part; The liquid oil plant is compressed into into liquid oil plant vapor lamp 2 certainly through valve 7.

Jockey valve door 8 before the igniting, store in oil gas in the oil plant basin along the direction shown in the arrow 9 through constant pressure valve 4, threeway 3 is opened and is made oil gas spray into body of heater behind the needle valve 6 to mix ignition with air.The liquid oil plant vapor lamp 2 that is placed in simultaneously on the stone or metal plate for standing a stove on as a precaution against fire is heated.Temperature when 2 is open valve 7 when liquid oil plant boiling point is above.Along the oil plant of direction liquid shown in the arrow 10 in basin 4 liquid oil plant 11 under the static pressure effect through valve 7, influent oil plant vapor lamp 2, the cracking of oil plant gasification portion of hot, formation has the gas stream of certain pressure, at threeway 3 punishment streams, the needle valve 6 of a part through having opened enters the body of heater burning, and another part feeds back to oil plant basin 5 through constant pressure valve.Gasification furnace promptly enters normal operating condition.

Close valve 7 when flame-out earlier, close needle valve 6 again, close valve 8 at last.

Needle valve 6 opening degrees control enters the oil and gas content of body of heater 1, and the oil mass that the control of valve 7 opening degrees enters liquid oil plant vapor lamp 2 is by valve 7 and needle valve and the control of the two opening degree and that the gasification furnace pipeline inner pressure is kept when the normal operation is constant.

It is 0.05～0.1 kilograms per centimeter that the pressure limit of constant pressure valve 4 is preferably in two ends pressure reduction ², open-minded at this pressure differential range internal feedback pipeline, keep constant automatically to keep feeding back to cracking gas 12 pressure that basin 5 is stored in liquid oil plant 11 upper spaces.

Basin 5 volumes are preferably in 30～35 liters, 10～15 liters of interior dress liquid oil plants.Oil plant adds under pressure, irritates oil for the first time and adds part low boiling oil plant such as liquefied gas simultaneously, makes liquid oil plant 11 top oil-air pressures reach 2.5 kilograms per centimeter ², must not pressure release in using continuously.Irritate internal pressure and can show that tank level is shown by liquid level meter 14 by tank deck Pressure gauge 13.Clear jar of back pours into oil plant by the mode of charging into for the first time.

Claims

1, be the gasification furnace of fuel with kerosene, diesel oil, heavy oil and other flammable liquid, particularly has part oil gas from the fuel oil gasification stove of presenting function, it is characterized in that gasification furnace has the liquid oil plant vapor lamp 2 of a filling zeolite catalyst, oil gas diversion three-way 3, and the oil gas backfeed loop of constant pressure valve 4 is housed, threeway 3 will feed back to oil plant basin 5 through constant pressure valve 4 through the oil gas shunting part of 2 gasifications of liquid oil plant vapor lamp and portion of hot cracking, and another part sprays into body of heater 1 burning through needle valve 6.

2, gasification furnace according to claim 1 is characterized in that filling zeolite catalyst in the liquid oil plant vapor lamp.

3, gasification furnace according to claim 1 is characterized in that constant pressure valve is 0.05～0.1 kilograms per centimeter in the pressure at two ends difference ²Open-minded in the scope.
