Abstract

PURPOSE:To make it possible to greatly shorten the time from the ignition to the stable combustion and to easily carry out fire extinguishment by using a ceramic heater as means for evaporating and igniting the fuel. CONSTITUTION:The fuel supplied by an external electromagnetic pump 15 is injected from the tip end of a nozzle 13. A part of air supplied by a blower 7 is supplied to a gap 14 formed in the periphery of the nozzle 13 through an inverted U-shaped pipe 16 or the like. The fuel which has been sprayed from the nozzle 13 is promoted its evaporation by the heat of the ceramic heater 9, and is supplied within the pot 3 together with air flowing through the gap 14. The evaporated fuel which has flowed into the pot 3 rises up while being mixed with primary air from a primary air hole 5, and burns by touching secondary air from a secondary air hole 6. Further, ignition of the fuel is performed by the ceramic heater 9.

Description

[Detailed description of the invention] The present invention relates to a Bott type combustion device.

Conventional pot-type combustion devices supply fuel such as petroleum to the inner bottom of the ITbot in a liquid state, ignite it and burn it, and after ignition, use its own combustion heat to promote the vaporization of the fuel.
This is configured to increase the amount of combustion. This P-type bot type combustion device has the advantage of a wide combustion range, but on the other hand, because the heat container in the vaporizing section is large, it takes a long time for Ymk at the bottom of the bot, which plays the role of evaporating the fuel, to stabilize. It usually takes several minutes, and it is difficult to shorten that time, so there is a disadvantage that it takes a relatively long time from ignition to the point where stable twisting and firing can be achieved.

Therefore, the applicant has already developed a device as shown in FIG. 1 in which a nozzle 16 is protruded on the inside gB of a ceramic heater 9, or since the heater 9 is arranged horizontally, fuel is dripped. In case, applicable,! , C) Receives heat and becomes small particles, which are dispersed and evaporate in the low-temperature part of the vaporized sli.

Therefore, in such a case, tar would be generated inside the ceramic heater 9, and in the worst case, an oil sump would occur, which was undesirable.

Therefore, the object of the present invention is to achieve stable combustion after ignition within σ months.
Thank you for providing a pot-type combustion device that takes less than 5 hours.

Furthermore, the present invention can shorten the time required for ignition and extinguishing, and improve vaporization efficiency.
The purpose is also to provide.

According to the present invention, a combustion chamber is provided in the upper blade of the bottomed pot, and in the combustion device, fuel and air are sent into the bottom for combustion, and the combustion chamber is arranged close to and facing the inner bottom surface of the bottomed bottom in an inclined position. a hollow cylindrical cefmic heater, and a nozzle for supplying fuel into the inside of the ceramic heater,
Inserting the nozzle into the inside of the Hiramic heater leaving a gap so that air can be introduced by following the gap,
Moreover, a vaporizing bot-type combustion coffin is provided, characterized in that the bottom bot has a transparent hole for supplying air for combustion on the side surface thereof, and the ceramic heater is used as a means for vaporizing and igniting the fuel. It will be done.

The vaporizing pot type combustion device of the present invention is configured to energize the ceramic heater, spray the fuel from the nozzle, supply it in a vaporized state into the pot, and burn it. The time required to extinguish the fire can be significantly shortened by .5 hours, and the time required to extinguish the fire can also be shortened because no fuel or liquid remains inside the bot.

In addition, since the ceramic heater, which serves as a means for vaporizing and igniting the fuel, is located away from the inner bottom surface of the bottomed bot, the inertia of the quick rise of heat of the heater alone can be reduced without considering the heat capacity of other parts of the bot. - It can be used for Shibetsu, and therefore the time for ignition can be shortened.

Moreover, since the heater is arranged in an inclined position, the fuel does not vaporize behind the nozzle tip due to its granular form, and the vaporized portion of so-called fuel A. Heat generating elements are arranged in the parts 1. By setting this part to an appropriate '1ine' level, vaporization can be carried out efficiently.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 shows a schematic configuration of an embodiment of the vaporizing Bott type combustion device '6 according to the present invention. A pot bar 2 is provided inside the device main body 1. This pot burner 2
is the same as the conventional bot-type combustion apparatus in that the flame holding device 4 is provided on all of the bottomed bots 6. The side wall of the sweet bottomed bot 6 has a through hole, that is, a primary air hole 5.
and a secondary air hole 6 are provided so that the air sent into the lower part of the device main body 1 by the blower 7 flows into the inside of the pot 6 through the primary air hole 5 and the secondary air hole 6. .

A hollow cylindrical ceramic heater 9 is inserted into the hole opened from the side of the device main body 1 and the bot B through the heater mounting plug 8 which serves as an insulator. The ceramic heater 9 is inserted into the pot 6 in an inclined manner and placed a little apart from the inner bottom surface of the pot 5. Thus, the ceramic heater 9 is thermally and electrically isolated from the device body 1 and the pot. ．They are virtually separated emotionally.

The ceramic heater 9 has a heating element 11 made of a tungsten pattern or the like on the front outer periphery near the tip of the nozzle 1. An electric cord 12 is connected to the heating element 11.
Heater power can be supplied from outside through the heater.

A nozzle 16 is inserted into the interior 12 of the cylindrical ceramic heater 9, leaving a gap 14 around it. Nozzle 1
The tip of the filter is located in the middle of the ceramic heater 9.

Fuel supplied by an external electromagnetic pump 15 is ejected from the light end of the nozzle 1.

A portion of the air from the blower 7 is supplied to the gap 14 around the sweet nozzle 13 through a reverse J-shaped pipe 16 or the like.

In this way, the fuel sprayed from the bottom of the nozzle 1 is accelerated to vaporize by the heat of the ceramic heater 9, and is supplied into the bot 6 together with the air flowing through the gap 14. The vaporized fuel that has flowed into the bot 6 rises while being mixed with the primary air from the primary air hole 5, and further comes into contact with the secondary air from the secondary air hole 6 to be combusted. Incidentally, the stone fire is also performed by the ceramic heater 9.

In this way, the liquid fuel is supplied into the fuel tank 6 as vaporized fuel F+, so the time from ignition to stable combustion 1 is greatly shortened, and extinguishing is also easy in a short period of time. φConsideration 4J-Suga-・J, -^ ・Since the device body 1 and the box +-3 are heated either electrically or thermally, the Ceraminoke Heater 9 is J1' of the heating element 11'\! At 11 volts, a rapid temperature rise will be obtained, so it is important to ignite in a short period of time.

Furthermore, since the heating element 9 is arranged in an inclined direction, the nozzle 1
The fuel emitted from the filter does not vaporize in the heater 9 behind the tip of the nozzle 1, and even within the so-called peak 9, the heat generating element 11 is placed at a high temperature f4)5.
Since it vaporizes in minutes, the vaporization can be carried out efficiently and the generation of tar can be prevented.

Since single vaporization can be performed efficiently, the amount of vaporized gas generated per unit time can be stabilized and good combustion can be performed.

Note that the shape of the ceramic heater 9 is not limited to a cylindrical shape, and may be a rectangular tube shape.
