Description
Technical field
This utility model relates to boiler structure technical field, particularly relate to a kind of separator outlet flue and
Multipath circulating fluidized bed hot-water boiler.
Background technology
The structure of existing multipath circulating fluidized bed hot-water boiler as it is shown in figure 1, include main combustion chamber 1,
The subsidiary combustion chamber 2 that is arranged in juxtaposition with main combustion chamber 1, secondary furnace 3, and be successively set on according to flue gas flow direction
The cyclone separator 4 of the follow-up flow process of secondary furnace 3, separator outlet flue 5 and back-end ductwork and afterbody are subject to
Hot side 6, this back-end ductwork and back-end surfaces 6 are provided with economizer.Secondary furnace 3 flue gas warp out
Cyclone separator 4 processes, and the flue-gas temperature being entered separator outlet flue 5 by central tube is higher,
Commonly reach and spend 500 more.For economy and safety, separator outlet flue 5 outermost layer is adiabatic
The hull-skin temperature of layer should be in the range of relevant criterion allows, therefore the setting of separator outlet flue 5
Meter is the link that multipath circulating fluidized bed hot-water boiler is very important.
In order to ensure that the hull-skin temperature of separator outlet flue 5 outermost layer heat insulation layer is permitted in relevant criterion
In the range of Xuing, the separator outlet flue 5 of existing Circulating Fluidized Bed Hot Water Boiler mainly uses such as
Lower three kinds of forms:
The structure of the first separator outlet flue 5 is as in figure 2 it is shown, it is by by backplate upper
The furnace wall 5-1 of castable refractory and insulated pouring material, top structure 5-2 and the domatic 5-3 of flue gas water conservancy diversion
Constitute.Furnace wall 5-1 is first to be welded into backplate by steel plate through chan frame, then pour into a mould guarantor on backplate successively
Temperature castable 502, castable refractory 501, one layer of rock cotton board 503 of paving in the channel-section steel of backplate.Top layer is tied
Structure 5-2 is followed successively by castable refractory 501, insulated pouring material 502, rock cotton board 503 from the bottom up.Cigarette
The domatic 5-3 of conductance stream is poured into a mould by castable refractory 501 and insulated pouring material 502 and forms.
The structure of the second separator outlet flue 5 is as it is shown on figure 3, its surrounding is to be formed by brick masonry
Furnace wall 5-1, top structure 5-2 formed by cast.The structure of furnace wall 5-1 is the most successively
Refractory brick 601, mechanism Rhizoma Begoniae Willsonii 602；Top structure 5-2 be followed successively by from top to bottom castable refractory 501,
Insulated pouring material 502, rock cotton board 503.
The third separator outlet flue 5 is heat resisting steel tobacco curing road, its structure as shown in Figure 4, from interior
Be followed successively by outward be welded heat-resisting steel sheet and plate 701, silicate aluminum board 702, rock cotton board 503.Heat resisting steel
Plate 701 can be high temperature resistant, but does not have heat insulation effect, in order to meet the temperature requirement of outer surface,
The silicate aluminum board that middle logical heat insulation effect is the most heat-resisting, outer layer adiabator rock cotton board.
By above three kinds of versions it can be seen that existing separator outlet flue is all adiabatic flue,
In order to ensure thermal insulation, will be by flame retardant coating, heat-insulation layer and this three-decker of heat insulation layer composition.For Zong
It, the flame retardant coating of the inside of the adiabatic flue of three of the above form substantial amounts of castable refractory, resistance to
Firebrick or heat-resisting steel sheet and plate, middle heat-insulation layer insulated pouring material or sky based on Rhizoma Begoniae Willsonii foundation
Air-casing, outside heat insulation layer rock cotton board to be used.And in order to ensure separator outlet flue 5 outermost layer
The hull-skin temperature of heat insulation layer is in the range of relevant criterion allows, and these three thermal insulation flue needs thicker
Thickness, this results in high expensive, installs loaded down with trivial details, and installation period is long.
It addition, above-mentioned three kinds of adiabatic flues of prior art all only have the merit of single flue gas circulation passage
Can, do not possess other function.
