Description

{HEATING AND HOT WATER HEAT MEDIUM OIL BOILER}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a heating medium oil boiler for both heating and hot water, and more particularly, to a heating medium oil boiler for heating hot water combined with hot water by means of heat medium oil rising and circulating from a heating medium oil tank to a plurality of cylindrical tubes.

Generally, an electric boiler uses hot water heated by an electric heater to heat cold water introduced through a water supply pipe. The hot water thus heated is used as heating or domestic water. Depending on the method of heating hot water, It is widely used because it is divided into boiler, and the risk of explosion or leakage of toxic gas is small, and it is small.

In recent years, interest in electric boilers has been rising as the advantages of low heating costs due to high oil prices are highlighted.

The heating device of the electric boiler according to the related art is provided with a coil heater or a direct heating heater in a heating furnace, heating the furnace by supplying cold water to the heating furnace, or a plurality of inner tubes arranged in layers, And a plurality of heating heaters are provided in the inner cylinder to heat the water while passing the cold water.

However, in the conventional electric boiler, when the heating cylinder is used as one unit, the volume of the heating cylinder is large and it takes a long time to heat the cold water injected into the heating cylinder. When the heating cylinder is formed in several layers, There is a problem that the production cost is increased due to the increase in the volume and the complexity of the structure.

In addition, since the internal flow rate of the heating cylinder is slowed by the natural flow rate, oil or limestone is formed around the heating heater at a high temperature to lower the thermal conductivity, shorten the life of the heating heater, and increase the electric consumption.

In addition, in order to supply a sufficient amount of circulating water to a hot water user in a short time, a lot of electric power is consumed. Therefore, in order to hot water hot water, a fossil fuel boiler is generally used. In order to compensate the existing shortcomings, As the tank is attached to the boiler itself, it becomes bulky and has drawbacks that greatly affect the life of the heater.

Induction heaters are composed of electromagnets through which high frequency alternating currents can pass. Eddy currents generated inside the metal by electromagnetic induction generate joule heat, and heat the magnetic (Heat).

The induction heater is composed of an electromagnet with a coil wound around a conductor. When an alternating current is passed through the coil, an alternating magnetic field is formed in the coil. At this time, an AC magnetic force is applied to the conductor, and an eddy current is generated by the electromagnetic induction phenomenon in the conductor, and the object bearing the magnetic body is heated by the generated heat of the current.

The induction heater has a characteristic of instantly generating a strong heat. In the past, it was mainly used in the industrial field, but recently it has been used in the household appliance. In order to generate heat by the induction heater, there is a limitation that a magnetic material including an iron (Fe) component must be included.

The conventional heater includes a first heating pipe, a second heating pipe, a floor space, a tertiary heating pipe, and magnesium as disclosed in Japanese Laid-Open Patent Publication No. 2011-043313 (published on Mar. 03, 2011) Depending on the electromagnetic induction, the exothermic agent moves the electron induction heating element capable of generating heat at a desired temperature at a high temperature of 500 ° C or higher, preferably 600 to 900 ° C, so that the metal particles and the glass, It has been proposed to solidify a solid material such as a film or cement and a kneaded material.

In addition, Patent Publication No. 0815719 (published on Mar. 20, 2008) discloses a structure for increasing a heat transfer efficiency by showing a second inner passage first inner cylinder, a passage and a case.

However, since the known technology requires a single electric boiler to provide a desired efficiency, it requires a lot of energy in order to heat the heating space to a desired temperature quickly and easily. Therefore, the drawback is that the efficiency is low and the cost is high Lt; / RTI >

A heating medium is a fluid used when heating or cooling a device to maintain a constant operating temperature, such as a heating medium oil, water, or mercury.

In industries where heat or cooling is required as heat, both heat mediums are used. The heating medium is usually circulated through a heat exchanger and must be liquid or gas at the temperature of use.

The materials used as the heat medium are the inorganics (oil) and inorganic salts that you know well. It depends on the purpose of use or the temperature of use.

Most homes or indoor heating use water and do not use oil. When the operating temperature is 400 ° C or higher, heat medium such as inorganic salt is used.

For industrial use -30 ~ 350 ℃ When using temperature, organic heat medium is used. It is called "heat medium oil" and it is called "Heat Transfer Fluids" in English.

In the present invention, the heating medium used in the combined heating and heating boilers is an organic compound as a "heating medium oil".

The characteristic feature of the above-mentioned heat oil is that it has a wide range of temperature at low pressure compared with water (each product is floating though it has a temperature range of about -30 ° C to 350 ° C), high heat conduction efficiency, energy saving and environmentally friendly, (The steam is expanded by about 10% when the temperature is raised by 100 ° C.), and the effluent is discharged at a temperature higher than 200 ° C. It is a fire hazard and should be kept out of contact with oxygen during use.

The type of heat medium oil is divided into several kinds according to the chemical structure of the product, the manufacturing method, the use state, etc. However, as for the user, the general mineral heat medium oil is mainly paraffin type organic material, While it is easy to use, it is easy to pyrolyze and can not be regenerated. It can be used economically when the temperature is 150 ~ 180 ℃.

Aromatic hydrothermal oil (also referred to as general synthetic hydrothermal oil) is a mixture of aromatic compounds, which is slightly expensive compared to general mineral thermal oil, but has good thermal stability.

Advanced synthetic thermal oils are a mixture of a single aromatic compound or a proportion of several aromatic compounds, mainly produced through a synthesis reaction. For example, products such as Therminal-66, vp-1, or Marlo therm-S of the United States. These products have good thermal stability, long service life and reproducibility, but they are expensive.

The synthetic oil system is composed of petroleum and synthetic oil. Synthetic oil systems include phenyl ether, polyphenyl, allylalkane, and alkbenzene. The synthetic oil system is widely used because it has excellent thermal oxidation stability, low vapor pressure, have.

Generally, petroleum is applied in a temperature range of -15 ~ 200 ℃, synthetic flow is applied in a wide range of -40 ~ 350 ℃.

Accordingly, the thermal oil of the present invention is a synthetic oil selected from phenyl ether, polyphenyl, allylalkane, and alkbenzene.

Next, the operation and effects of the heat and oil heating oil boiler of the present invention constructed as described above will be described.
