The apparatus comprises a frame which can support the installation of heat sustaining materials, manufactured from heat resistant materials. It is also preferable to have at least 2 columns of bases extended along the side of the frame for supporting the installment. Heat sustaining materials are installed on the surface of the frame, the said materials are provided in the form of square or curved plate, which forms a square, polygonal or cylindrical shaped frame. The plates must have at least one pore, and must be punched to allow passage of air for ventilation of air and heat. The size of pores is varied depending on type of fuel being used.; The heat exchange is conducted by heat conduction and radiation. The surface where heat radiation takes place may be varied by height in order to ensure the heat distribution and circulation. The plate at one end of the frame has a curved or straight profile for directing the flame toward the side surface of the frame. This will ensure circulation of flame on the side surface, and sustaining heat. The present invention improves the performance through the continuous heat radiation from heat sustaining materials.

Description

Heat exchanger

Technical field

The present invention relates to combustion system, for burn or with accumulation of heat and heat release, accumulation of heat and the heat release of relevant other process of burning.

Background technology

Boiler has been designed to allow the combination of the heat exchange of a kind of heat exchange or three kinds of forms, instant heating conduction, thermal convection current and heat radiation at present.Wherein, compare with other method, heat radiation can exchange the heat of 60% ratio conventionally, is considered to the most effective.Heat radiation is similar to the heat of passing through air being caused by solar radiation and transmits, through the space of earth atmosphere and finally arrive the material of solid or liquid form.

But, in order to make boiler be suitable for commercial Application, still need boiler to further develop the degree that the performance in heat exchanger is improved, and reduce required fuel grade.Along with development, also should reduce boiler and use the pollution causing.Exist improving the industry of the boiler of design at present needs and demand, to allow carrying out effective heat exchange aspect the heat exchange of water, reduces the fuel for burning, and minimizes the pollution that the burning that occurs in boiler causes.

Summary of the invention

Therefore, the object of the present invention is to provide a kind ofly for keeping and discharge the device of the heat of boiler, it is kept material, for covering the framework of at least some part of boiler, is formed by heat.Framework is tubular or polygonal shape preferably.The surface of framework is configured to install described heat and keeps material.This device also comprises the Ventilation Control mechanism for improvement of the performance with management devices.

Described framework can comprise a plurality of small frame connected to one another.Described small frame can disconnect, to adjust the size of whole framework, thereby adapts to the size of boiler, and the size of boiler can be as the case may be and different.This is to install in order to raise the efficiency and to provide easily, but also any potential damage that can avoid the variation due to the shape and size of boiler to be applied to cause.

This device is characterised in that, preferably the multiple heat of floor form keeps material to be placed on tightly on the surface of framework.Framework also can be installed on vertically or the boiler of level.

In one aspect, heat keeps the surperficial porosity of material to change.Also the material shape of various ways be can provide, triangle, rectangle, polygon, crooked or tubular plate comprised.Then described plate can be installed on framework, and this framework is made by the heat proof material that can use at the temperature up to 800 ℃.Framework can have a plurality of connection table surface layers.For multiple-level surface, between every layer, be provided with space, to allow heat to keep installation and the layout of material, and between every layer, reach the suitable heat exchange of required grade.Further preferably, the heat that is positioned at the layer of more close boiler keeps the porosity of material to be greater than the porosity of another layer.

On the other hand, heat keep material and framework can together with manufacture the part on framework surface, to avoid material subsequent installation on framework.

On the other hand, framework is configured at one end comprise plate, to control direction and the corresponding air circulation of flame.This be in order to ensure the heat loop distribution from burner on whole framework.Framework also can be assembled to for supporting the base of boiler.

Due to above-mentioned feature, for the device keeping and discharge the heat of boiler, allow effective heat exchange and effectively utilize fuel and the energy of burning.The installation that described device also facilitates according to the feature of boiler, and before having increased in heat is distributed to fire tube for keeping the space of heat.

The specific embodiment

Fig. 1 shows preferred embodiment, and in the figure, it is arranged on boiler or needs in the large fire tube of other device or the outlet of combustion chamber 2 that heat operates.General characteristic is tube-shaped tube, comprising:

-supporting hot keeps structure or the framework 21 of material 11, by having identical stable on heating heat proof material, manufactures.Two row bases are arranged on a side place of framework, for supporting and be installed on boiler.

The heat of-plate form keeps material 11 to be arranged on the surface of cylindrical shell.Described material is that heat keeps material, for the heat exchange of convection current and forms of radiation, can carry out air and heat ventilation.These plates can be arranged to square, crooked and tubular.

It can be one or more layers that-Re keeps the number of plies of material, as shown in Figure 2, and to increase the performance in heat exchanging process.The number of plies can change according to the size of the pipe 2 using in boiler and burner 8.

-the heat of close boiler keeps material 11 to be slightly larger than the size of burner 8, and along the fire tube of boiler or the distribution of lengths of combustion chamber 2.Heat will accumulate in the first innermost layer 11 places, arrive as the outer field second layer subsequently by convection current and radiation delivery.This succeeding layer further transfers heat to other exterior layer.Therefore, heat is distributed in whole combustion chamber, and then heat will circulate and be delivered to the wall of fire tube 2 and fire tube 3, so that Continuous Heat exchange, as depicted in figs. 1 and 2.

-air flows through the anterior of fire tube 2 and heat is transmitted towards fire tube 3.This air can be from chimney or from the air in other source, air-blaster 4,5, as shown in Figure 1.

-framework can be divided into a series of short framework, with any infringement that prevents from causing material to expand and cause due to heat.Can assemble described small frame, until obtain according to the required length of use of the size of the fire tube 2 of boiler.Heat keeps material to load as shown in Figure 4 and Figure 5.

-the plate (if any) that is arranged on tubular one end makes flame be directed into the side surface of cylindrical shell for controlling the direction of flame, causes thus flame to circulate and allow along side surface and carries out Continuous Heat exchange by radiation.

Alternatively, can tubular triangular in shape or polygonal shape for the framework of heat maintenance material is installed.

In other form of the present invention, heat maintenance material can manufacture a surperficial part of framework, as shown in Figure 6.

The present invention can reduce the use of fuels sources effectively by the better heat exchange of heat radiation form, and reduces thermal loss.This contributes to manufacture and contribute to the temperature in smooth combustion chamber, thereby prevents any variation.

It should be appreciated by those skilled in the art that and the invention is not restricted to illustrate especially and describe above.On the contrary, scope of the present invention comprises combination and sub-portfolio and modification and the modification of feature described above, and all these may occur for a person skilled in the art and not belong to prior art after reading foregoing description.
