Abstract
The utility model relates to a media material for an infrared burner. Alloy fiber with diameter less than 50 microns is sintered into sheet material with the weight of 3 to 4 kg/m<2> and the thickness of 2 mm, and the sheet material is taken as the base material, then the sheet material is processed into perforated sheet material with 20 to 25 percent of percentage of opening by using a mechanical processing method, and finally a fireresistant compound coating layer of titanium oxide, ferric oxide and silicon oxide is covered on the surface of the material.
Description
Affiliated technical field
Infrared burner all needs a media material, and burning and ultrared release are all carried out on the surface of this media material.The utility model is a kind of media material that is exclusively used in infrared burner.
Background technology
Because thermal efficiency height, advantage such as the CO of discharging and NOx concentration are low, infrared burner has obtained using very widely.But the media material of present infrared burner is mainly porous ceramic plate, secondly is woven wire and metallic fiber material.
Ceramic material is crisp, does not have toughness, be easy to because reasons such as machinery strike and thermal expansion are damaged, and the area thermic load is less; The easy tempering of infrared burner with the woven wire making; The burner of making of metallic fiber material (braiding or sintering) can partly overcome above defect, prevent tempering and reduce two requirements of material circulating resistance but often be difficult to take into account, can not satisfy the requirement of the low pressure nature injection of higher load especially, in addition, the decay resistance of metal material is relatively poor.
Summary of the invention
In order to overcome the deficiency of other media material, the utility model provides a kind of media material that is used to make infrared burner, this material not only resistance is little, and can effectively stop tempering, decay resistance and high temperature oxidation resistance also strengthen, and can satisfy the requirement of the low pressure nature injection of higher load fully.
The technical scheme that its technical problem that solves the utility model adopts is: sinter diameter into weight 3-4kg/m less than 50 microns alloy fiber under vacuum state
2, the about 2mm of thickness sheet material, as base material, be processed to form the porous sheet material of percent opening 20-25% then with the machining mode, at the high temperature resistant composite coating of material surface capping oxidation titanium, iron oxide and silica, the size that just can cut into corresponding specification is then as required used at last.
The beneficial effects of the utility model are that heat-resisting expansion character, resistance to elevated temperatures, decay resistance and the radiance of this material all improve, and can effectively overcome the shortcoming of ceramic media material and other metal media material.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a plane of the present utility model, and Fig. 2 is a profile.
Among the figure, 1. metallic fiber base material, 2. hole, 3. high temperature resistant composite coating.
The specific embodiment
In Fig. 1 and Fig. 2, on the metallic fiber base material (1) of sinter molding, process uniform hole (2), evenly cover high temperature resistant composite coating (3) on the surface of metallic fiber base material (1) then.
Claims (4)
1. the media material of an infrared burner is characterized in that: process uniform aperture on the metallic fiber base material of sinter molding, then at its surface coverage high-temperaure coating.
2. the media material of a kind of infrared burner according to claim 1 is characterized in that: base material is to sinter weight 3-4kg/m by diameter into less than 50 microns alloy fiber under vacuum state
2, the about 2mm of thickness sheet material.
3. the media material of a kind of infrared burner according to claim 1 is characterized in that: percent opening 20-25%.
4. the media material of a kind of infrared burner according to claim 1 is characterized in that: at the high temperature resistant composite coating of surface coverage titanium oxide, iron oxide and the silica of base material.
