Description

EXCHANGED! * OF HEAT FIELD OF THE INVENTION The present invention relates to combustion system, heat storage and heat release for combustion or other processes in connection with combustion, heat storage and heat release.

BACKGROUND OF THE INVENTION The boiler is currently designed to allow one or combination of three forms of heat exchange, ie heat conduction, heat convection and heat radiation. Among which, heat radiation is normally able to exchange heat in a proportion of 60%, which is considered to be more effective when compared to other methods. The heat radiation is similar to the heat transfer caused by solar radiation through the air, the space of the Earth's atmosphere and eventually to the materials in solid or liquid form.

However, for the boiler adapted for industrial use, further development of the boiler is still necessary to the extent that the performance in the heat exchanger is improved and the level of fuel required decreases. With the development, the pollution that is provoked for the use of the boiler must also decrease. There is a need and industrial demand for the improvement of a boiler currently designed to allow the exchange of heat in terms of effectiveness by exchanging heat for water and reducing fuel for combustion, as well as minimizing the pollution of combustion that takes place in the boiler.

BRIEF DESCRIPTION OF THE INVENTION Therefore, it is the object of the present invention to provide an apparatus for storing and releasing heat for boilers, which is composed of materials that maintain heat, in the racks to cover at least certain parts of the boiler. The frame is preferably cylindrical, circular or polygonal. The surface of the frame is configured for the installation of the mentioned heat maintenance materials. The device also includes a ventilation control mechanism to improve and manage the performance of the device.

The frame can comprise a plurality of small frames connected together, The small frame can be disconnected to adjust the overall size of the frames to accommodate the size of the boiler which can be different depending on each case. This is to improve the effectiveness and provide ease of installation, and also to avoid any potential damage due to the variation in the shape and size of the boiler to which it is applied.

The apparatus is characterized in that a plurality of heat holding materials, preferably in the form of a plate, is placed closely on the surface of the frame. The frame can also be installed with the vertical or horizontal boiler.

In one case, the porosity of the surface of the heat maintenance materials may vary. The shape of the materials can also be provided in various forms including a triangular, rectangular, polygonal, curved or cylindrical plate. The plates can then be installed with the frame that is made of heat-resistant materials capable of being used at temperatures up to 800 ° C. The frame can have multiple connected layers of surface. For the multilayer surface, a space is provided between each layer to allow the installation and arrangement of materials to maintain heat, and achieve a desired level of adequate heat exchange between each layer. It is also preferable that the porosity of the materials to keep the heat located in the layer closest to the boiler is greater than that of the other layer.

In another aspect, the heat maintaining materials and the frame can be fabricated together as a part of the surface of the frame to avoid subsequent installations of materials to the frame.

In another aspect, the frame is configured to include a plate in one and to control the direction of the flame and the corresponding air circulation. This is to ensure that the heat from the burner circulates and is distributed through the frame. The frame can also be assembled to a base to support the boiler.

With the features mentioned in the foregoing, the apparatus for storing and releasing heat for boilers allows the efficient exchange of heat and the effective use of fuel and energy for combustion. The apparatus also provides ease of installation in accordance with the feature of the boiler and increases the space for heat maintenance before the heat is distributed within the radiant tube.

Figure 4 shows the characteristics of the support frame for storage / heat release plates which are divided into short series.

DETAILED DESCRIPTIONS OF THE PREFERRED MODALITY The preferred embodiment is shown as in Figure 1 in which it is installed at the outlet of the long radiant tube or combustion chamber (2) of the boiler or other apparatus that requires heat for its operation. The general characteristic is a cylindrical tube that is composed of - Structure or Frame (21) that supports the materials to keep the heat (11) manufactured from Heat-resistant materials that have the same heat tolerance. The two columns of bases are provided on one side of the frame to accommodate the support and installation with the boiler.

Materials are installed to maintain heat (11) in the form of plates on the surface of the cylinder. The materials are materials to maintain heat, capable of ventilation of air and heat for the exchange of heat in the form of convection and radiation. These plates can be provided in square, curved and cylindrical shapes.

The number of layers of heat storage / release materials can be one or multiple as shown in Figure 2 to increase the performance in the heat exchange process. The number of layers may vary depending on the size of the tube (2) and the burner (8) used in the boiler.

The materials for maintaining the heat (11) that are closest to the boiler are slightly longer than the burner (8) and are distributed along the length of the radiant tube or combustion chamber (2) of the boiler. Heat will accumulate in the first layer of the inner end (11) and the Subsequent transfer to the second layer which is the outer layer by convection and radiation. The subsequent layer will also transfer heat to the other outer layers. Therefore, the heat is distributed throughout the combustion chamber, then the heat will circulate and will be transferred to the wall of the radiant tube (2) and to the radiant tube (3) for continuous heat exchange as shown in Figure 1 and 2.

The air flows through the front of the radiant tube (2) and transfers heat to the radiant tube (3). The air can be air from the chimney or from other sources, that is, a fan (4, 5) as shown in Figure 1.

The frame can be divided into a series of short frames to avoid any damage from the expansion of materials due to heat. The small frames can be assembled until the desired length is acquired for use according to the size of the radiant tube (2) of the boiler. The materials to keep the heat can be charged as shown in Figure 4 and Figure 5.

The plate placed at one end of the cylindrical shape, (if any) is used to control the direction of the flame to the degree that the flame is directed towards the lateral surface of the cylinder, thus causing the circulation of the flame along the lateral surface and allowing the continuous exchange of heat by radiation.

Alternatively, the frame for the installation of materials to maintain heat may be triangular, cylindrical or polygonal.

In another form of the invention, the material for maintaining heat can be manufactured as a part of the surface of the frame as shown in Figure 6.

The present invention can effectively reduce the use of fuel resource through a better heat exchange in the form of heat radiation and the reduction of heat loss. This helps in the manufacture and stabilization of the temperature in the stable combustion chamber, so it avoids any change.

Thus, the above description of various embodiments of heat exchanger was given for purposes of illustration and example. Those skilled in the art will appreciate that the present invention can be carried out in other forms than those specifically set forth herein without departing from the essential features of the invention. The present modalities of this In all cases, they should be considered as illustrative and not restrictive, and all changes that fall within the scope of meaning and equivalence of the appended claims are intended to be included in them.
