Aiming at overcoming the defects that according to an existing heat transfer element of an industrial furnace, heat radiation quantity is not high and oriented radiation is difficult to form, the utility model provides an oriented reinforcement radiation heat transfer element of an industrial furnace. The oriented reinforcement radiation heat transfer element is cavity-type fireproofing materials, heat accumulation micropores are arranged in the fireproofing materials, and heat accumulation additives are arranged in the heat accumulation micropores. As an improvement, the fireproofing materials are cone-shaped or square-shaped, and the length-diameter ratio L /R of a cavity of the fireproofing materials is 1.3-1.7. The oriented reinforcement radiation heat transfer element of the industrial furnace has the advantages that fuel combustion in the furnace can be accelerated; emissivity can reach 0.96; and compared with comprehensive heat efficiency and fuel energy conservation of a normal heat transfer element, comprehensive heat efficiency of the heat transfer element can be improved by about 10%, and fuel energy conservation can be improved by 12%-15%.

Description

The directed radiation industrial furnace heat transfer element of strengthening
Technical field
This applicable industries stove firing equipment field is specifically related to a kind of directed radiation industrial furnace heat transfer element of strengthening that forms.
Background technology
So far, in order to improve the thermal efficiency of industry heating stove, taked to be intended to reduce the light-duty furnace building material of accumulation of heat loss and radiation loss, also or with increasing the burner hearth area come augmentation of heat transfer, or be coated with high emissivity coating, also have and in burner hearth, install the technology such as device that change heat transfer type additional at inboard wall of burner hearth.Adopt light-duty furnace building material, can strengthen thermal insulation, reduce heat loss; Be coated with high emissivity coating at inboard wall of burner hearth, can increase radiation intensity; Improve furnace wall heat radiation area, can increase total radiation.Also have to adopt to carry the method for black matrix furnace building material, though can solve emissivity and directional transmissions problem in the cavity, make it only account for the very little part of the gross area, do not make whole burner hearth interior wall all bring up to 0.96 emissivity.
Summary of the invention
The technical problems to be solved in the utility model is: for the not high deficiency with being difficult to form directed radiation of existing industrial furnace heat transfer element thermal exposure, provide a kind of and can accelerate the stove fuel combustion, emissivity can reach 0.96 orientation reinforcement radiation industrial furnace heat transfer element.
The utility model solves the problems of the technologies described above the technical scheme of taking: a kind of directed radiation industrial furnace heat transfer element of strengthening, comprise the cavity type refractory material, and the heat accumulation micropore is arranged in the described refractory material, described heat accumulation micropore includes the heat accumulation additive.
As improvement of the present utility model, described refractory material is conical or tetragonal shaped body.
As further improvement of the utility model, the draw ratio L/R of the cavity of described refractory material is 1.3~1.7.
Further improve as of the present utility model, described refractory material is located on the furnace wall, and its normal direction is over against workpiece.
The utility model increases the heat accumulation function of whole refractory material by the dual way of establishing the heat accumulation micropore and adding the heat accumulation additive in refractory material, form brand-new high thermal storage refractory, and this material makes than former refractory material that temperature improves about 100 ℃ in the stove.The present invention also utilizes the cavity heat radiation principle except making common cubic brick shaped material, refractory material is made the cavity type shaped body, and is installed on normal over against the furnace wall position of heated body, forms ultrared directional transmissions.
Its design principle is: by increasing the heat accumulation function of whole refractory material, can improve the actual temperature of the inner lining material of heating furnace, thereby the gap of having dwindled furnace wall and flame kernel temperature has improved the interior mean temperature of burner hearth.According to Ali Ni Wusi law: 10 ° of C of the every raising of the environment temperature of substance reaction, its reaction speed increases by 1 ~ 2 times.Stove fuel combustion speed is accelerated, and the total amount of heat that discharges in the unit interval increases, and that is to say that the heat that can supply with the heating body is more.And the raising of common square refractory brick Yin Wendu has strengthened thermal radiation capability, and this refractory brick is made as again shaped body, and external form is taken from the standard industry black matrix, and cavity size L:R=1.3 ~ 1.7 are owing to adopting the cavity radiation principle that emissivity is reached ε=0.96, because the increase of surface area has strengthened radiating surface---realized ultrared directional transmissions, made heated body obtain more heat.By the heat conservation law as can be known, the heat that heated body obtains is many, and its exhaust emissions temperature will inevitably correspondingly descend.So far, three parts of the thermal efficiency, efficiency of combustion, heat exchange efficiency and thermal balance efficient all obtain raising in various degree.Accelerate the burn rate of fuel in the industrial furnace by application of the present utility model, improved average furnace temperature; Strengthen thermal exposure and reached directed radiation; Shorten the heating-up time of heated body, thereby improved thermal efficiency of heating furnace, reached fuel-saving purpose.According to measuring and calculating, the more conventional heat transfer element integrated heat efficiency of the utility model can improve about 10%, and the fuel energy-saving rate can improve 12 ~ 15%.
