Description
Technical field
The present invention relates to boiler technology field, especially, relate to a kind of gas fired-boiler furnace wall structure.
Background technology
The various heating surfaces of boiler must be surrounded the flow channel of the flue gases such as formed burner hearth and flue by furnace wall, for
Different parts or the furnace wall of different operating condition, in performance so that the requirement in structure should also be as being different.Generally for cigarette
The furnace wall at the positions such as temperature burner hearth more than 900 DEG C and high temperature convection pass requires higher.Furnace wall is long-term and high-temperature flue gas
Contact, therefore it is required that have resistant to elevated temperatures ability and the characteristic of opposing ash attack, and to have good heat-insulating property, Yi Mianxiang
The outer amount of heat that scatters and disappears: in order to flue gas leakage, must holding furnace to outside stove in preventing outside air from leaking into burner hearth or during pressure combustion
The air-tightness of wall.Traditional gas fired-boiler furnace wall typically uses refractory brick to form with heat-barrier material, this relatively simple for structure, no
The most fire-resistant bad with air-tightness, and service life is short, need to often safeguard.
Summary of the invention
Present invention aim at providing a kind of gas fired-boiler furnace wall structure, to solve in prior art, furnace wall is fire-resistant and gas
Close property is bad, the problem that service life is short.
For achieving the above object, the present invention provides a kind of gas fired-boiler furnace wall structure, including: piled up by refractory fireclay block and
The flame retardant coating become, the thickness of described flame retardant coating is 100mm-120mm；Thickness it is disposed with from the inside to the outside on described flame retardant coating
The heat insulation layer of 60mm-65mm, the heat-insulation layer of thickness 20mm-25mm and the sealant of thickness 3mm-5mm；Described heat insulation layer is by density
Less than 1000kg/m3, heat conductivity is less than the material composition of 0.29W/ (m DEG C) when 20 DEG C, and described heat-insulation layer is asbestos board,
Described sealant is steel plate.
Further, the expansion clearance between two blocks of described refractory fireclay blocks adjacent in described flame retardant coating is not more than 3mm, institute
State filled stone cotton cord in expansion clearance.
Further, described heat insulation layer is piled up by diatomite brick and is formed, the adjacent expansion between two blocks of described diatomite bricks
Two strands or three strands of asbestos cords are filled in gap.
The method have the advantages that
This boiler furnace wall structure fire resistance is good, and during boiler operatiopn, the temperature outside furnace wall is not above 60 DEG C, logical outside furnace wall
Cross sheet metal to seal, there is good air-tightness, also greatly strengthen the service life of furnace wall simultaneously.
Accompanying drawing explanation
Below with reference to figure, the present invention is further detailed explanation.The accompanying drawing of the part constituting the application is used for
Thering is provided a further understanding of the present invention, the schematic description and description of the present invention is used for explaining the present invention, is not intended that
Inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation of gas fired-boiler furnace wall structure preferred embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail.
Referring to Fig. 1, the preferred embodiments of the present invention provide a kind of gas fired-boiler furnace wall structure, including: resistance to by clay
The flame retardant coating 1 that firebrick is piled up, the thickness of described flame retardant coating 1 is 100mm-120mm；Depend on from the inside to the outside on described flame retardant coating 1
The sealant 4 of the secondary heat-insulation layer 3 and thickness 3mm-5mm being provided with the heat insulation layer 2 of thickness 60mm-65mm, thickness 20mm-25mm；
Described heat insulation layer 2 is less than 1000kg/m by density3, heat conductivity is less than the material composition of 0.29W/ (m DEG C), institute when 20 DEG C
Stating heat-insulation layer 3 is asbestos board, and described sealant 4 is steel plate.This boiler furnace wall structure fire resistance is good, furnace wall during boiler operatiopn
The temperature in outside is not above 60 DEG C, is sealed by sheet metal outside furnace wall, has good air-tightness, is also greatly enhanced simultaneously
Service life of furnace wall.
Preferably, for improving service life and refractory heat-insulating performance, the phase in described flame retardant coating 1 of flame retardant coating 1 and heat insulation layer 2
The adjacent expansion clearance between two blocks of described refractory fireclay blocks is not more than 3mm, filled stone cotton cord in described expansion clearance；Described thermal insulation
Layer 2 is piled up by diatomite brick and to be formed, and two strands or three strands of asbestos cords are filled in the expansion clearance between two blocks of adjacent described diatomite bricks.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention；Skill for this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies
Change, equivalent, improvement etc., should be included within the scope of the present invention.
