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.
Boiler has been currently designed to allow one or the combination of three forms of heat exchange; namely heat conduction, heat convection and heat radiation. Among which, heat radiation is normally capable of exchanging heat at a proportion of 60% which is considered to be most effective when compared to other methods. The heat radiation is similar to the transfer of heat caused by the sun's radiation through air, space the earth's atmosphere and eventually to materials in solid or liquid form.
However, for the boiler adapted for industrial use, it is still necessary to further develop the boiler to the extent that the performance in heat exchanger is improved and the level of the required fuel is decreased. With the development, the pollution caused by use of boiler should also be decreased. There are industrial needs and demands for improvement of boiler currently designed to allow heat exchange in terms of effectiveness in exchanging heat for water and reducing fuel for combustion, as well as minimizing pollution from combustion taken place in the boiler.
It is therefore the objective of the invention to provide an apparatus for storing and releasing heat for boilers, which consists of heat sustaining materials, the frames for covering at least a certain part of the boiler. The frame is preferably in cylindrical circular or polygonal shape. The surface of the frame is configured to the installment of the said heat sustaining materials. The apparatus further includes a ventilation control mechanism for improving and managing the performance of the apparatus.
The said frame may comprise a plurality of small frames connected to each other. Said small frame can be disconnected in order to adjust the size of the overall frames for accommodating the size of boiler which may be different depending on the case by case basis. This is to enhance effectiveness and provide ease of installation, and also to avoid any potential damages due to the variation in shape and size of boiler to be applied with.
The apparatus is characterized in that a plurality of heat sustaining materials preferably in the form of plate, are closely placed on the surface of the frame. The frame can be further installed with the vertical or horizontal boiler.
In one aspect, the porosity of surface of heal sustaining materials may be varied. The shape of materials can also be provided in several forms including triangular, rectangular, polygonal, curved or cylindrical plate. The said plates can then be installed with the frame which is made of heat resistant materials capable of the usage in the temperature of up to 800° C. The frame can have multiple connected layers of surface. For multilayer surface, a space is provided between each layer in order to allow installation and arrangement of heat sustaining materials, and achieve a desired level of appropriate heat exchange between each layer. It is also preferable that the porosity of the heat sustaining materials located at the layer closer to the boiler is greater than that of the other layer.
In another aspect, heat sustaining materials and frame can be altogether manufactured as a part of the frame surface in order to avoid subsequent installations of materials to the frame.
In another aspect, the frame is configured to include a plate at one end in order to control the direction of flame and the corresponding air circulation. This is to ensure that heat from the burner is circulated distributed throughout the frame. The frame can also be assembled to a base for supporting the boiler.
With the aforementioned characteristics, the apparatus for storing and releasing heat for boilers, allows efficient heat exchange and the effective, use of fuel and energy for combustion. The said apparatus also provides ease of installation in accordance with the characteristic of boiler and increases the space for the sustaining of heat before the heat is distributed into the fire tube.

FIG. 6—demonstrating the structure of the invention in the event that the frame and heat storage/release materials are produced and installed as one piece.
The preferred embodiment is shown as in
Alternately, the frame for installment of heat sustaining materials can be in triangular cylindrical or polygonal shape.
In other form of the invention, heat sustaining material can be manufactured as one part of surface of frame as shown in
The present invention can effectively reduce the use of fuel resource through a better heat exchange in form of heat radiation and the reduction of heat loss. This assists in manufacturing and stabilizing the temperature in combustion chamber stable, thereby preventing any change.
Thus, the preceding 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 may be carried out in other ways than those specifically set forth herein without departing from essential characteristics of the invention. The present embodiments are thus to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
