Abstract
The utility model relates to the field of the refractory material, in particular relates to an inner lining refractory material that is used for the inner wall of the heating hearth such as a boiler. The utility model provides a multi-function refractory brick that is used for the inner wall of the hearth, which comprises a brick body, and is characterized in that the interior of the brick body is provided with a plurality of transverse pore canals and vertical pore canals, which are communicated with each other, wherein, the transverse pore canals pass through both end surfaces of the brick body; the vertical pore canals pass through the upper surface and the lower surface of the brick body. The brick body consists of alumina cement, alumina aggregate and solid combustion supporter by the weight ratio of 1:5:2. The multi-function refractory brick has the advantages that the combustion is more adequate, the combustion at the main combustion zone is optimized, the stopping time of the combustible gas in the hearth is prolonged, and the heat radiation is strengthened to favor the adequate combustion.
Description
Technical field
The utility model relates to fire resisting material field, and specifically, it belongs to the liner type refractory material that is used for heating furnace inwalls such as boiler.
Background technology
The inner lining refractory block that existing conventional boiler brickwork is used is a solid brick, and ventilating hole channel is not set, and can not influence the fired state of the interior wind direction of burner hearth and pneumatic power effect and comburant, thereby can not improve the combustion efficiency of boiler.Therefore the burning of traditional burner hearth is generally insufficient, not only waste energy, and discharge burn not completely that fuel gas and particle also can cause great pollution to environment, be unfavorable for energy-saving and emission-reduction, the protection environment.
Summary of the invention
For overcoming above-mentioned deficiency of the prior art; the purpose of this utility model just provides a kind of Multifunction refractory brick that is used for inboard wall of burner hearth as liner; it can be by influencing wind direction and pneumatic power effect in the burner hearth; strengthen heat radiation; improve the burner hearth combustion efficiency, reach the purpose of energy-saving and emission-reduction, protection environment.
For achieving the above object, the technical solution adopted in the utility model provides a kind of multi-functional refractory brick that is used for inboard wall of burner hearth, described multi-functional refractory brick comprises the brick body, it is characterized in that, brick body inside is provided with horizontal duct and the vertical duct that is communicated with each other, described horizontal duct connects two end surfaces of brick body, and described vertical duct connects brick body upper surface and lower surface.
Described brick body is that 1: 5: 2 ratio is formed by alumina cement, alumina aggregate and oxidizing solids with weight ratio.
Compared with prior art, the beneficial effects of the utility model are:
1, by forming burning cavity one by one in the function brick, not clean-burning combustible is carried out second-time burning, make burning more abundant;
2, be that the primary zone replenishes a large amount of oxygen by function wind, the burning in primary zone is optimized;
3, multi-functional wind can make the wind direction of burner hearth main air duct form turbulent flow, and the time lengthening that combustion gas is stopped in furnace chamber has been strengthened heat radiation simultaneously and has been beneficial to abundant burning.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Also the utility model is described in further detail in conjunction with the accompanying drawings below by specific embodiment, and following embodiment is only used for explanation rather than restriction the utility model.
As shown in the figure, be provided with horizontal and vertical duct in the multi-functional refractory brick body 1, vertical duct 4 connects brick body upper surface 2 and lower surface, and laterally duct 5 connects two end surfaces 3 of brick body, and is communicated with each other between horizontal duct 5 and the vertical duct 4.As preferred version, be in together on the same section parallel with side 6 vertical duct 4 and laterally duct 5 in brick body 1, be communicated with each other, be between the duct on the different sections and be not communicated with, at this moment, the side 6 of brick body 1 is a confining surface, does not have the duct outlet.
The appearance and size of multi-functional refractory brick body 1 can decide according to installation site in the dissimilar boilers, and its size certainly, also can be made less size as required generally greater than traditional anophthalmia refractory brick.Its length dimension is generally the 400-1500 millimeter, and width dimensions is the 200-500 millimeter, and gauge is the 100-200 millimeter.
Duct quantity on the multi-functional refractory brick body 1, the needs setting that can ventilate according to the size and the duct of brick body, usually, laterally eyelet quantity is 3-12, and horizontally-arranged duct row's number is 1-3 row, and vertical duct quantity is 6-20, and vertical eyelet row number is 2-6 row.The size in duct also can be provided with voluntarily according to the size of brick body and the needs of ventilation, and its diameter is generally the 5-50 millimeter.
Multi-functional refractory brick body 1 is that 1: 5: 2 ratio is made by alumina cement, alumina aggregate and oxidizing solids with weight ratio.
During use, the utility model is adhered on the furnace chamber inwall, the vertical duct of brick body bottom can communicate with the air compartment that function wind can be provided, and the duct of an end surfaces of brick body is in furnace chamber; Certainly, also the brick body vertically can be adhered in the furnace chamber, at this moment, the horizontal duct of brick body bottom just communicates with the air compartment that function wind can be provided, and the vertical duct on the upper surface of brick body is in furnace chamber at this moment.When boiler in when burning, have hot blast to feed in the duct of brick body, form respiration, boiler smoke is sucked by the duct, bottom, by breathing out in the duct, top, so just form burning cavity one by one through the burning back, not clean-burning combustible is played the effect of second-time burning.The duct blows in the interior function wind of burner hearth contains a large amount of hot oxygen, for the primary zone has replenished the necessary combustion adjuvant that burns, burning is optimized is carried out.
Claims (2)
1, a kind of multi-functional refractory brick that is used for inboard wall of burner hearth, described multi-functional refractory brick comprises the brick body, it is characterized in that, brick body inside is provided with horizontal duct and the vertical duct that is communicated with each other, described horizontal duct connects two end surfaces of brick body, and described vertical duct connects brick body upper surface and lower surface.
2, a kind of multi-functional refractory brick that is used for inboard wall of burner hearth according to claim 1, it is characterized in that, described horizontal duct is being in connection each other on the same section parallel with the brick body side surface with vertical duct, is between the duct on the different sections not to be communicated with.
