Description

Spiral combustion device

The present invention relates to a spiral combustion device, and more specifically, to a spiral combustion device that can cause combustion by supplying fuel through a pipe inside the combustion device.

Global warming is rapidly progressing due to an increase in carbon dioxide generated from the use of fossil fuels, and interest in alternative energy that can replace fossil fuels is increasing.

Interest in alternative energy led to the creation of the term green growth, and as interest in green growth grew, efforts were made to use eco-friendly liquid animal and vegetable oils as fuel for combustion devices rather than existing fossil fuels. This is being done.

In the case of fossil fuels, carbon dioxide is emitted when burned, and the emitted carbon dioxide is causing global warming. Of course, carbon dioxide is emitted when vegetable oil is burned, but if the carbon dioxide generated when vegetable oil is burned is combined with the carbon dioxide absorbed by the plant when it grows, the amount of carbon dioxide produced through vegetable oil can be considered as zero.

Despite these advantages, liquid animal and vegetable oils could not be used as fuel for combustion devices. The reason is that in order to be used as a general fuel oil, ignition properties must be good and viscosity must be low, but liquid animal and vegetable oils have high ignition points, so ignition properties are not good and the viscosity is high, so a lot of tar is generated.

Due to these characteristics, in order to use liquid animal and vegetable oil as fuel oil, the liquid animal and vegetable oil must be processed to have a low viscosity, but processing liquid animal and vegetable oil requires a lot of cost, making it uneconomical.

In addition, a wick is placed inside the combustion device to increase ignition, but it has the disadvantage of being inconvenient to add a wick during each ignition process and the ash generated when the wick burns reduces the durability of the combustion device.

In addition, even if the wick is placed at the bottom of the combustion device and burned together with the fuel, the temperature inside the combustion device is not appropriate due to the thermal bridge phenomenon caused by the external temperature difference, and the flame attached to the wick and fuel frequently goes out.

Therefore, there is an urgent need to develop a combustion device that can use liquid animal and vegetable oils with poor ignition properties and high viscosity as fuel oil without processing them.

The object of the present invention is to provide a spiral combustion device that can ignite fuel without using a wick in a pipe.

Another object of the present invention is to provide a spiral combustion device that can create an environment in which fuel is easy to ignite by blocking the thermal bridge phenomenon caused by external temperature differences.

Another object of the present invention is to provide a spiral combustion device that can minimize tar accumulation in pipes and easily maintain cleanliness inside the combustion device.

A spiral combustion device according to one aspect of the present invention for achieving the above object includes a body provided with fuel, a combustion chamber for burning the fuel inside the body, and an igniter disposed inside the combustion chamber to ignite the fuel. It may be provided with a spiral plate formed inside the combustion chamber, ignited through the igniter, and combusting fuel at a certain distance from the body.

The spiral plate may be provided with a supply pipe connected to the body to supply fuel, and a spiral plate formed on an upper part of the supply pipe and spaced a certain distance away from the body to combust the fuel while supplying a certain amount of fuel to the igniter.

The spiral plate includes a body plate assembled at the top of the supply pipe, a supply hole through which the center of the body plate is drilled to expose one end of the supply pipe, and a protrusion in the form of a spiral protrudes from one side of the body plate based on the supply hole. A spiral guide that supplies fuel to the igniter may be provided.

The spiral guide is connected to a supply section for supplying fuel, a combustion section to which a portion of the supplied fuel is maintained and the flame ignited by the igniter is transferred, and is connected to the combustion section to supply fuel to the igniter. It may be provided with an ignition section that connects the flame to the combustion section while supplying and burning it.

The spiral plate may be provided with a guide groove that guides the fuel to fall into the hollow portion of the ignition section.

The guide groove may be provided with an ignition zone so that the fuel falling from the ignition section can easily transfer flame through the igniter.

The supply pipe may have a curved pipe that is bent in the direction in which the igniter is located to increase the temperature of the fuel provided therein.

According to the spiral combustion device according to the present invention, the fuel falling in the ignition section is combusted by the igniter, and the flame is transferred along the falling fuel to ignite the fuel provided in the combustion section.

In addition, since the spiral plate is spaced a certain distance from the body, a temperature sufficient to combust fuel within the body can be created without the flame being extinguished by external temperature differences.

In addition, the fuel spreads widely according to the guidance of the spiral guide, and the amount of fuel falling from the ignition section is reduced by the flame transferred to the combustion section, thereby maintaining cleanliness inside the body.
