Description
Technical field
The utility model relates to a kind of infrared radiation heating device, particularly a kind of energy accumulating plate for infrared radiation heating.
Background technology
The heating process of industrial furnace is to rely on convection current, conduction and the heat radiation of heat to realize that heat exchange at high temperature mainly relies on heat radiation, and hot conduction can be ignored.Common heating element heater or body of heater are transferred to the heat that is heated workpiece and are: Q=α
Convection currentA (T-T
0)+λ ε
TA (T
4-T
0 4), in the formula:
α
Convection currentBe convective heat-transfer coefficient
A is a heating surface (area) (HS
λ is a radiation wavelength
ε
THeat emissivity coefficient for heating
T is heating element heater (or furnace wall) temperature, T
0Temperature for workpiece
At high temperature, a heat radiation in the formula becomes the major part of thermal energy transfer, and it is directly proportional with the difference of biquadratic of temperature between heating element heater and the workpiece, also is directly proportional with heat emissivity coefficient (thermal emissivity rate).As seen, improve the thermal efficiency and can realize, enhance productivity the purpose of energy savings thereby reach by the thermal emissivity rate that improves furnace wall reflection or heating element heater surface.Usually in the furnace wall or heating element heater surface-coated oxide coating, as ceramic composite, the general radiation rate is 83%, and requires this oxide coating to have stability at elevated temperature and high-temperature heat-resistance shock resistance, and the thermal coefficient of expansion of coating is little, is convenient to requirements such as construction.
Britain Fuijikura Euorope company has adopted common aluminium to obtain obvious energy-saving effect with steel plate is compound afterwards as the wall lining of drying oven after black anodizing, and its radiance is identical with oxide coating.
