Next, the operational effects of the present invention configured as described above are as follows.

First, as shown in FIG. 3, when the rotary atomizing combustion unit 1 turns on the main switch (not shown), the upper cap (10) is fixedly attached to the lower part of the internal burner body 51 to form a mixing space chamber ( 73) and the preheat heater 72 fixedly attached around the lower cap 71 to preheat the mixed space chamber for a few seconds, so that when using a gasoline with poor quality compared to normal condition evaporation temperature, such as kerosene, When the vaporization temperature of about 260 ° C. and the vaporization temperature of about 250 ° C. that can be vaporized when kerosene is used are selectively varied by a selection button of a control unit (not shown), the thermistor 56 may cause this normal condition vaporization. By sensing the temperature, the electronic palm 80 and the blower motor 66 are operated in response to a signal of a microcomputer (not shown).

That is, when the liquid fuel pumped by the electromagnetic pump 80 passes through the nozzle pipe 75 along the white arrow and is injected from the nozzle 75a disposed in the spray dish 78, the liquid fuel is rotated by the motor 62. By the rotation of the spray pan 78 and the spray pan 77 interlocked in accordance with the rotational force of the) is raised to the top along the surface of the spray pan 78, and the zone and the spray pan (78) supporting the spray pan 77 The atomized liquid fuel is ejected through the fine gap formed between the and the vaporized liquid in contact with the preheating heater 72 disposed on the outer circumferential surface of the lower cap 71.

At this time, another combustion air blowing fan (65) disposed outside the blower body (54) and wrapped by the blower case (60) is rotated in conjunction with driving of the blower motor (66). It is supplied to the mixed space chamber formed by combining the upper cap 73 and the lower cap 71 along the path indicated by the black arrow through the air filter 64 and the blower case 60 for inducing combustion air. The combustion air is heated by the preheating heater 72 disposed on the outer circumferential surface of the lower cap 71 and mixed with the vaporized liquid fuel to form a mixed gas. Then, the mixed gas passes through the passage hole 71a formed in the lower cap 71 by the combustion air supply pressure and the spray fan 77, and is formed between the outer burner body 50 and the inner burner body 51. As it rises through the formed space and is discharged to the outside through the plurality of flame holes 51a formed on the upper circumference of the inner burner body 51, it is ignited by the igniter 53 to form a flame.

On the other hand, as shown in FIG. 4, when the pot-type combustion unit 2 turns on the main switch (not shown), the preheating heater 6 embedded in the upper bulge portion 10c of the inner burner body 10 is turned on. If the inner burner body 10 is preheated for a few seconds and maintained at a normal condition vaporization temperature, for example, a vaporization temperature of about 250 ° C. that can vaporize kerosene, the thermistor 4 senses this normal condition vaporization temperature. In accordance with the signal of the microcomputer (not shown) to operate the electronic pump and the blowing means not shown.

That is, the combustion air and liquid fuel ejected into the inner burner main body 10 from the combustion air supply pipe 23 and the oil supply pipe 22 by the driving of the blower means and the electronic pump which are not shown in the figure of the side wall part 10a. When heated by the heat of the preheating heater 6 embedded in the bulge 10c and becomes a mixed gas, the mixed gas acts as a venturi tube formed in the flange portion 12b of the induction member 12 ( The pressure difference of 12c increases rapidly toward the rectifying plate 17, and the mixed gas passes through the discharge hole 17a of the rectifying plate 17 and at the same time the upper portion of the rectifying plate 17. The inner and intermediate metal nets 15 (14) and the salt holes 12a through the gap formed by the ceiling of the mixer 18 and the heat shield plate 19 through the outlet hole 18a of the mixer 18 disposed in the chamber. And guided to the outer metal mesh 13 is discharged.

At this time, the mixed gas discharged through the salt hole 12a of the pot-type combustion unit 2 is ignited by the igniter 53 fixedly attached to the rotary atomizing combustion unit 1 to perform combustion. The mixed gas discharged through the flame hole 51a of the rotary atomization combustion unit 1 is ignited by the igniter 53, so that the pot-type combustion unit 2 and the rotary atomization combustion unit 1 are eventually ignited. ) Is ignited by one igniter (53), of course, one frame rod 52 is located in the generally opposite direction of the igniter (53) so that the pot-type combustion section (2) and rotary atomizing combustion section Needless to say, the flame formed in the salt holes 12a and 51a of (1) is sensed.

In addition, the inner burner body 10 of the pot-type combustion unit 2 is formed in the salt hole 51a of the rotary atomizing combustion unit 1 and the salt hole 12a of the pot-type combustion unit 2. It is to receive periodic radiant heat by high temperature combustion heat, so it is possible to maintain the normal conditions of vaporization temperature which can vaporize the mixed fuel supplied from the oil feed pipe 22 and the combustion air supply pipe 23 at all times. In order to maintain the vaporization temperature, the amount of power consumed when the power is frequently applied to the preheater 6 can be reduced, and the vaporization temperature is prevented from changing due to frequent temperature changes, resulting in increased vaporization efficiency. The combustion efficiency can be improved and the generation of tar can also be reduced.

As described above, the dual-combustion structure of the heating device of the present invention has a calorific value of 15000 kW / H using a kerosene-type potable combustion unit having a calorific value of 5000 kW / H and light oil or kerosene. Since it consists of a dual combustion structure incorporating a rotary atomized combustion unit having a heating element, a calorific value of 20000 2000 / H or more, which is the sum of the calorific value of the maximum calorific value of 5000㎉ / H and the maximum calorific value of 15000㎉ / H, is obtained. It is possible to provide a mobile medium-sized heating equipment that can satisfy the needs of consumers, and also can be used together with kerosene and diesel oil, there is a fuel cost reduction effect.
