Description
Technical field
The utility model relates to industrial furnace technology field, particularly relates to a kind of accumulation of heat novel change spin crossover flame burner nozzle brick.
Background technology
Burner block is one of critical piece of various industrial heating furnace, existing burner block generally uses heavy refractory brick or the cast of heavy castable refractory to be formed, the lower burner block of part serviceability temperature adopts light fire brick and light heat-insulating material cast to form, the burner block conventionally formed have weight large, install that fixing difficulty is large, heat insulation effect is poor, radiation loss is large and the defect such as energy waste is serious; In addition on the one hand, existing burner position is higher, after furnace chargeization is flat, flame contact is less than aluminium liquid surface, and cause fusing time long, natural gas motorcar rate is low, the supply of aluminium liquid is not gone up, burner block angle design is unreasonable, the direct torch firing of flame, and the flame direction of ejection is wayward, firedoor frame, furnace wall, furnace roof (lid) are easily burnt distortion, poorly sealed, runout, smelting time is long, and smelting efficiency is low.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of accumulation of heat novel change spin crossover flame burner nozzle brick, can increase heat output, prevents structure such as damage firedoor frame, furnace wall etc., improves smelting efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of accumulation of heat novel change spin crossover flame burner nozzle brick, comprise burner block body and to be opened in the middle part of burner block body and the variable cross-section glory hole of through burner block body, described variable cross-section glory hole end is provided with cylindric through hole.
Described variable cross-section glory hole comprises cambered surface and lower camber side, described upper cambered surface and lower camber side both sides tangent, the cross section of described upper cambered surface is semicircle camber line, the cross section of described lower camber side is upper shed parabola, angle between described lower camber side bearing of trend and upper cambered surface bearing of trend is 10-20 degree, and the direction of the cylindric through-bore axis of described glory hole end is consistent with upper cambered surface bearing of trend.
The corundum indefinite form of described burner block body employing quick drying is fire-resistant prevents disclosing material mixture siliceous with corundum carbon, and the quality proportioning of bi-material is 1:1.
The beneficial effect adopting technique scheme to produce is: by arranging variable cross-section glory hole, variable cross-section glory hole end is supporting arranges one section of cylindric through hole, flame combustion rotary speed is increased, achieve flame front burning velocity to change along with burner block, define variable cross-section swirl flame, the depletion rate of variable cross-section flame laminar flow in heat storage burner brick is changed along with the change in variable cross-section glory hole cross section, increase heat output, decrease thermal energy consumption, change burning length and the direction of flame, Flame of Natural Gas equivalent increases, 1.5 are increased to from existing 0.5, do not waste flame heat of high temperature, reduce firedoor frame, furnace wall, the flame impingement of furnace roof (lid) and scaling loss, improve smelting efficiency, improve natural gas motorcar rate.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model partly cuts open structural representation;
In the accompanying drawings: 1, burner block body; 2, variable cross-section glory hole; 3, cylindric through hole.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Low in order to solve existing burner block smelting efficiency, easily to firedoor frame, furnace wall and furnace roof cause the problem of washing away with scaling loss, the utility model provides a kind of accumulation of heat as shown in Figure 1-2 novel change spin crossover flame burner nozzle brick, comprise burner block body 1 and be opened in the middle part of burner block body 1, and the variable cross-section glory hole 2 of through burner block body 1, burner block body shape can set according to smelting furnace mounting structure, it can be regular rectangular structure, also can be other polymorphic structures, set bolt can also be set in its end, its key improvements is: described variable cross-section glory hole 2 end is provided with cylindric through hole 3, described variable cross-section glory hole 2 comprises cambered surface and lower camber side, described upper cambered surface and lower camber side both sides tangent, the cross section of described upper cambered surface is semicircle camber line, the cross section of described lower camber side is upper shed parabola, angle between described lower camber side bearing of trend and upper cambered surface bearing of trend is 10-20 degree, the sectional area of the variable cross-section glory hole that upper cambered surface and lower camber side are formed from front to back (front and back position is see accompanying drawing 1 and accompanying drawing 2) reduces gradually, cylindric through hole 3 axis direction of described glory hole end is consistent with upper cambered surface bearing of trend, described burner block body 1 adopts that the corundum indefinite form of quick drying is fire-resistant anti-to be disclosed and baker 48 hours siliceous material mixtures of corundum carbon, the mixing quality proportioning of two kinds of material is 1:1, the corundum indefinite form used in the utility model fire-resistant anti-disclose adopt the applicant in application in 2013 patent of invention disclosed in material be as the criterion that (this application for a patent for invention number is: 201310502702.5), the model of the siliceous material of corundum carbon is wherein KX9998, when concrete use, to be cast in shaper after two kinds of material proportionally mixing, complete burner block cast.
The manufacturing step of burner block of the present utility model is as follows:
First shape fabricating cast outer mold is related to according to burner block, use withstand voltage foam to substitute existing timber or steel making core simultaneously, cost can be saved, and core is located in outer mold, certainly, outer mold can directly use the hole on smelting furnace furnace wall to serve as, without the need to arranging special outer mold, directly by the reserving hole inner position of core on smelting furnace furnace wall, and by closed at both ends;
Then casting mixture outside core, material to be mixed solidifies the rear demoulding can form the utility model burner block required for protection.
In a word, burner block disclosed in the utility model is by arranging variable cross-section glory hole, variable cross-section glory hole end is supporting arranges one section of cylindric through hole, flame combustion rotary speed is increased, achieve flame front burning velocity to change along with burner block, define variable cross-section swirl flame, the depletion rate of variable cross-section flame laminar flow in heat storage burner brick is changed along with the change in variable cross-section glory hole cross section, increase heat output, decrease thermal energy consumption, change burning length and the direction of flame, Flame of Natural Gas equivalent increases, 1.5 are increased to from existing 0.5, do not waste flame heat of high temperature, reduce firedoor frame, furnace wall, the flame impingement of furnace roof (lid) and scaling loss, improve smelting efficiency, improve natural gas motorcar rate.
