Abstract

PURPOSE:To prevent kerosene from being vaporized at the same time that kerosene enters a vaporizer even in the case where the amount of kerosene supplied is small by providing heat radiating fins on a fuel feed pipe, which is apt to be heated, in the vicinity of the kerosene vaporizer. CONSTITUTION:A fuel feed pipe 20 is heated by heat generated by a vaporizer 30 in the vicinity of the vaporizer during the operation of combustion. Especially, in the case where a kerosene input (the amount of kerosene supplied) by an electromagnetic oil pump 10 is small, the flow rate of kerosene passing through the fuel feed pipe 20 is small; therefore, kerosene in the fuel feed pipe 20 is heated up to a considerably high temperature just before entering the vaporizer 30. Accordingly, heat radiating fins 70 are provided on the fuel feed pipe 20 in the vicinity of the vaporizer 30 and, by cooling the heat radiating fins 70 with cooling air introduced through an air inlet port 80 provided on the side wall of a combustion chamber 3, heat of the fuel feed pipe 20 is rapidly radiated via the heat radiating fins 70, and a temperature rise at the fuel feed pipe 20 can be prevented. Therefore, kerosene that has entered the vaporizer 30 is not instantly vaporized.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an oil vaporization combustor equipped with an oil vaporizer.

<Prior art and its issues> Conventionally, in oil vaporization combustors used in oil hot air heaters, etc., in order to reduce the power consumption of the heater for heating oil vaporization, a heat receiving part is provided in the vaporizer. , a part of the combustion heat is used to heat the vaporizer.

However, if the oil input (oil supply, amount) to the vaporizer decreases while the vaporizer is being heated by the combustion heat, the oil will be heated to a high temperature in the oil pipe that sends the oil to the vaporizer, causing it to vaporize. When it enters the vessel, it is instantly vaporized, and as a result,
The drawback was that the combustion was pulsating, matching the frequency of the oil pump.

Therefore, the present invention solves the above-mentioned drawbacks of the prior art, and even when the oil input to the carburetor is small, the oil that enters the carburetor is not instantaneously vaporized, and the oil vaporization combustion that does not cause pulsating combustion. The purpose is to provide equipment.

Means for Solving the Problems> In order to achieve the above object, the oil vaporization combustor of the present invention has the following features:
In addition to the heating heater, the oil vaporizer is equipped with a heat receiving part that receives combustion heat, and the oil sent through the oil pipe is gasified in the vaporization chamber of the oil vaporizer and sent to the combustion pipe, where it is combusted. An oil vaporization combustor for combustion in a chamber,
The present invention is characterized in that a heat radiation fin is provided on the oil feed pipe near the oil vaporizer, and an air intake port is provided on the combustion chamber wall near the heat radiator fin.

<Function> Since heat radiation fins are provided on the oil pipe near the oil vaporizer, which is easily heated, heat from the oil vaporizer side is released through the heat radiation fins. Moreover, the air entering from the air intake port provided on the wall of the combustion chamber near the heat radiation fins cools the heat radiation fins, and as a result, the temperature rise in the oil pipe is suppressed. Therefore, even if the amount of supplied oil is small, it is prevented from being heated to a high temperature in the oil pipe before entering the vaporizer. Therefore, it is not instantaneously vaporized upon entry into the vaporizer (and pulsating combustion is also eliminated).

<Example> Figure 1 is a configuration diagram of an oil hot air heater which is an embodiment of the oil vaporization combustor of the present invention, seen from the side, Figure 2 is the same (configuration diagram seen from the front, and Figure 3 is an oil vaporization combustor). It is a block diagram of a container.

Reference numeral 1 denotes a case of an oil hot air heater, and a blower fan 2 is provided on the back side of the case 1, and a combustion chamber 3 is provided within the case 1. A combustion pipe 4 is disposed in the combustion chamber 3, and the gas combusted on the upper surface of the combustion pipe 4 is guided forward and downward from the ceiling of the combustion chamber 3, and becomes warm air from the outlet 5 on the front of the heater. It is blown out.

An oil vaporizer 30 vaporizes the oil sent from the oil pipe 20 and sends it to the combustion pipe 4. The carburetor 30 is provided with a heat receiving section 33 that receives combustion heat from the combustion chamber 3 . Furthermore, a heat radiation fin 70 is provided near the connection portion of the oil pipe 20 to the oil vaporizer 30. An air intake port 80 is provided in the side wall 3a of the combustion chamber 3 located near the heat radiation fins 70.

Due to the rotation of the blower fan 2, air flows into the combustion chamber through the air intake port 80, and the "radiating fins 70" flow into the combustion chamber.
promotes heat dissipation.

As shown in FIG. 3, the oil vaporizer 30 is connected to an oil feed pipe 20 from a tank (not shown) by an electromagnetic oil pump lO.
The oil sent through is introduced into the vaporization chamber 31 and vaporized. A mesh body 60 in the form of a wire mesh is installed inside the vaporization chamber 31. 50 is a heater for heating. The vaporized petroleum is blown into the combustion tube 4 from the nozzle 32 together with air. 34 is a needle valve of the nozzle 32; 35 is a solenoid that moves the needle valve 34 forward and backward;
36 is a return vibe, and 37 is a temperature sensor.

During combustion operation, the oil pipe 20 tends to be heated by heat from the carburetor 30 in the vicinity of the carburetor. Therefore, especially when the oil input (oil supply amount) by the electromagnetic oil pump 10 is small, the flow rate of oil passing through the oil pipe 20 is small, and unless some measure is taken, the oil will not be sent before entering the vaporizer 30. There is a possibility that the temperature inside the oil pipe 20 is already quite high. In the present invention, the heat radiation fins 70 are provided in the oil pipe 20 near the carburetor 30,
In addition, since the heat radiation fins 70 are cooled by cold air from the air intake port 80 provided on the side wall of the combustion chamber 3, the heat of the oil pipe 20 is transferred to the heat radiation fins 70.
Heat is quickly radiated through the oil pipe 20, and a rise in temperature of the oil pipe 20 is prevented. This also prevents the oil sent through it from being heated to high temperatures.

Effect> The present invention has the above configuration, and according to the oil vaporization combustor according to claim 1, a heat radiation fin is provided in the oil pipe, and an air intake port is provided in the combustion chamber wall near the heat radiation fin. Therefore, the temperature of the oil pipe can be sufficiently lowered by the cold air entering from the air intake port effectively removing heat from the heat radiation fins. Therefore, even when the oil supply flow rate is small, high-temperature preheating of the oil is prevented, and the oil that has entered the vaporizer is prevented from being instantaneously vaporized. Therefore, pulsating vaporization of petroleum in accordance with the supply frequency of the oil pump and thereby pulsating combustion are prevented, and stable combustion can be achieved even at low capacity operation.
