The heat efficiency of the blower boiler combustor lining using the structure is greatly raised, besides, the utility model has the advantages of convenient construction, a short construction period, low investment, simple operation method, reduced labor intensity and shortened construction period.

Description

New and effective gas blowing boiler combustion chamber liner
Technical field
The new and effective gas blowing boiler of the utility model combustion chamber liner relates generally to gas combustion chamber boiler liner, especially gas blowing boiler combustion chamber, chemical industry synthetic ammonia field liner.
Background technology
Gas making discharging waste gas---the recovery key equipment gas blowing boiler combustion chamber of blowing-out gas in the present Ammonia Production flow process, its traditional inner lining structure is: interior fire-resistant outer insulation, be to adopt refractory brick or castable refractory in the combustion chamber, thickness reaches 230---350mm, the combustion chamber cylindrical shell adopts the diatomite insulation construction outward, and thickness is about 300mm, referring to shown in Figure 1, heat-insulation layer 8 is attached to the outside of furnace wall 4, the flame retardant coating 6,7 that the inside of furnace wall 4 has refractory brick to make.This inner lining structure exists following shortcoming:
1, gas enters with tangent line, and liner is washed away greatly, and fragile refractory material causes leaking out, scurrying fire;
2, use the heavy special form brick to do the ball topping material, weight is big, and the production and processing difficulty is big, is difficult to guarantee construction quality;
3, because poor insulation property needs very thick outer insulation, not only increase investment but also increased the cylindrical shell wall temperature, shortened the cylindrical shell life-span;
4, cylindrical shell wall temperature height, equipment is fragile, and maintenance capacity is big, the parking rate height;
5, the body of heater deadweight is bigger, makes troubles for civil Engineering Design, construction, has increased the design and construction difficulty.
Summary of the invention
The purpose of this invention is to provide a kind of new and effective gas blowing boiler combustion chamber liner, it has overcome the defective of above-mentioned existing gas blowing boiler combustion chamber inner lining structure, and reached the thermal efficiency and significantly improved, and the purpose that easy construction, duration are short, investment is low.
The technical solution of the utility model is a kind of gas blowing boiler combustion chamber liner, comprises top construction and chamber structure, bottom construction, it is characterized in that the furnace roof liner adopts the cast of steel fiber castable lattice; The burner hearth liner is divided into three layers, is respectively flame retardant coating, thermal insulation layer, heat-insulation layer from inside to outside.
Above-mentioned new and effective gas blowing boiler combustion chamber liner, described flame retardant coating is the heavy alumina firebrick, and thermal insulation layer is the lightweight alumina firebrick, and heat-insulation layer is the aluminosilicate refractory fiber brick.
Above-mentioned new and effective gas blowing boiler combustion chamber liner, the thickness of described furnace roof steel fiber castable is 400mm.
Above-mentioned new and effective gas blowing boiler combustion chamber liner, be that furnace bottom is back taper at the bottom of; Tapered bottom surface is the thick steel fibre castable refractory of 400mm, all the other space filling normal concretes.
Above-mentioned new and effective gas blowing boiler combustion chamber liner leaves the liner dilatation joint at furnace roof and burner hearth junction.
Adopt the gas blowing boiler combustion chamber liner thermal efficiency of said structure significantly to improve, and easy construction, the duration is short, investment is low; Its method is simple to operate, and labour intensity reduces greatly, and the duration shortens greatly.
Description of drawings
Fig. 1 is a prior art gas blowing boiler combustion chamber inner lining structure schematic diagram.
Fig. 2 is the utility model gas blowing boiler combustion chamber inner lining structure schematic diagram.
Fig. 3 is the utility model gas blowing boiler combustion chamber inner lining structure dilatation joint schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
See Fig. 2, shown in Figure 3, the technical solution of the utility model comprises top construction 1 and chamber structure 2, bottom construction 3, top construction 1 liner adopts the cast of steel fiber castable lattice, comprises steel fiber castable layer 11 and fills up the anti-or fiber brick heat-insulation layer 12 of broken alumina silicate; The cast of steel fiber castable layer 11 lattice leaves dilatation joint between the lattice dative; Further form can be that the thickness of furnace roof steel fiber castable is 400mm.Burner hearth liner 2 is divided into three layers, is respectively flame retardant coating 21, thermal insulation layer 22, heat-insulation layer 23 from inside to outside.Flame retardant coating shown in Fig. 2 embodiment 21 is the heavy alumina firebrick, and thermal insulation layer 22 is the lightweight alumina firebrick, and heat-insulation layer 23 is the aluminosilicate refractory fiber brick; These three layers all place within the furnace wall 4.Leave liner dilatation joint 5 in furnace roof 1 and burner hearth 2 junctions, see shown in Figure 3ly, be filled with alumina silicate fiber felt in this dilatation joint 5, the expansion that is beneficial to liner is shunk.At the bottom of furnace bottom 3 is back taper; Tapered bottom surface is the thick steel fibre refractory casting of the 400mm bed of material 31, all the other space filling normal concretes 32.
Adopt the gas blowing boiler combustion chamber liner thermal efficiency of said structure significantly to improve, and easy construction, the duration is short, investment is low; Its method is simple to operate, and labour intensity reduces greatly, and the duration shortens greatly.
The utility model gas blowing boiler combustion chamber liner, its preparation method is:
1., remove stove inner surface greasy dirt, rust cleaning;
2., the welding bitch, the cast normal concrete is built column by laying bricks or stones, the cast castable refractory, the template of a big arch is built brick arch by laying bricks or stones;
3., paste 150 thick aluminosilicate refractory fiber bricks with the 8101# high-temperature agglomerant;
4., the THA-1 refractory wass is built 80 thick LZ-0.7 high-alumina lightening fireproof insulation bricks by laying bricks or stones;
5., the THA-1 refractory wass is built 220 thick LZ-65 high-alumina refractory bricks by laying bricks or stones;
6., stay in the designed elevation position and establish dilatation joint;
