Description
Technical field
The utility model relates to the large-scale hot-water boiler of a kind of forced circulation membrane wall structure waterpipe type.
Background technology
The large-scale hot-water boiler of forced circulation membrane wall structure waterpipe type is the used large-scale hot-water boiler product of a kind of public utilities central heating.
The combustion problem that utilizes the grate firing mode to solve boiler is the simplest mode of the large-scale hot-water boiler of operation and maintenance.Because China does not break through the technical bottleneck of big heating load all the time on the grate firing type coal combustion technology, cause the maximization of grate firing boiler to be restricted.
Summary of the invention
The utility model technical issues that need to address just are to overcome the defective of prior art, provide a kind of forced circulation membrane wall structure waterpipe type large-scale hot-water boiler, the utility model adopts the forced circulation film water cold wall structure, reduced every input of central heating equipment, efficient, safety, environmental protection, energy-conservation.
For addressing the above problem, the utility model adopts following technical scheme:
The large-scale hot-water boiler of a kind of forced circulation membrane wall structure of the utility model waterpipe type comprises boiler furnace and burner hearth; Be provided with the fin panel casing of sealing around the described burner hearth, be provided with four road water-cooled screens in the burner hearth, the burner hearth rear portion is provided with coiled pipe convection heating surface and air preheater.
Described burner hearth bottom is provided with crossbeam type chain-grate.
Described furnace outlet place is furnished with finned tube and carries out flue dust separation in the stove.
The utility model has been arranged four road water-cooled screens in proportion in the burner hearth that fin panel casing surrounds, the burner hearth rear portion is coiled pipe convection heating surface and air preheater.Backwater is introduced from the convection heating surface upper collecting chamber, arrive its next part case through coiled pipe, arrive rear arch next part case through tube connector, to the upper drum cold water area, divide two-way through down-comer through rear arched tube, the one tunnel shields its upper collecting chamber through water-cooled, another road two side walls are to its upper collecting chamber, compile after preceding down-comer to face arch collection case, to the drum hydrothermal area, infeeds outer net through gas collecting apparatus through preceding arch tube through mixing header.The water circulation is forced circulation in the stove.
The utility model has solved the maximization problem of big capacity forced circulation film water cold wall structure watertube boiler, has reduced every input of central heating equipment.
Advantage of the present utility model has:
1. heating surface has adopted fin panel casing around the burner hearth, is furnished with four film-type water-cooling screens in the burner hearth, and heat transfer efficiency height, burner hearth good airproof performance are convenient to adopt light boiler setting in the burner hearth.
2. adopted the forced circulation mode, water speed is high in the heating surface tube, stable and reliable operation.Water speed is high in the pipe in the zone that thermic load is high when structural configuration, and the interior water speed of zone pipe that thermic load is low is low, thereby has guaranteed that water is subjected to thermal balance in the pipe, and the leaving water temperature deviation is little.
3. the convection heating surface pipe adopts coiled pipe to arrange along row.No dust stratification heat-transfer effect is good.
4. employing crossbeam type chain-grate, cloth wind evenly, the fire grate good seal performance, the fire grate stable and reliable operation.
5. the furnace outlet place arranges that finned tube carries out flue dust separation in the stove, is provided with the dedusting in stove device, and the initial dust-density emission of boiler is low.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the large-scale hot-water boiler of a kind of forced circulation membrane wall structure of the utility model waterpipe type comprises boiler furnace 1 and burner hearth 2; Be provided with the fin panel casing 3 of sealing around the described burner hearth, be provided with four road water-cooled screens 4 in the burner hearth, the burner hearth rear portion is provided with coiled pipe convection heating surface 5 and air preheater 6.
Described burner hearth bottom is provided with crossbeam type chain-grate 7.
Described furnace outlet place is furnished with finned tube 8 and carries out flue dust separation in the stove.
The utility model has been arranged four road water-cooled screens in proportion in the burner hearth that fin panel casing surrounds, the burner hearth rear portion is coiled pipe convection heating surface and air preheater.Backwater is introduced from the convection heating surface upper collecting chamber, arrive its next part case through coiled pipe, arrive rear arch next part case through tube connector, to the upper drum cold water area, divide two-way through down-comer through rear arched tube, the one tunnel shields its upper collecting chamber through water-cooled, another road two side walls are to its upper collecting chamber, compile after preceding down-comer to face arch collection case, to the drum hydrothermal area, infeeds outer net through gas collecting apparatus through preceding arch tube through mixing header.The water circulation is forced circulation in the stove.
The utility model has solved the maximization problem of big capacity forced circulation film water cold wall structure watertube boiler, has reduced every input of central heating equipment.
The utility model:
1. heating surface has adopted fin panel casing around the burner hearth, is furnished with four film-type water-cooling screens in the burner hearth, and heat transfer efficiency height, burner hearth good airproof performance are convenient to adopt light boiler setting in the burner hearth.
2. adopted the forced circulation mode, water speed is high in the heating surface tube, stable and reliable operation.Water speed is high in the pipe in the zone that thermic load is high when structural configuration, and the interior water speed of zone pipe that thermic load is low is low, thereby has guaranteed that water is subjected to thermal balance in the pipe, and the leaving water temperature deviation is little.
3. the convection heating surface pipe adopts coiled pipe to arrange along row.No dust stratification heat-transfer effect is good.
4. employing crossbeam type chain-grate, cloth wind evenly, the fire grate good seal performance, the fire grate stable and reliable operation.
5. the furnace outlet place arranges that finned tube carries out flue dust separation in the stove, is provided with the dedusting in stove device, and the initial dust-density emission of boiler is low.
It should be noted that at last: obviously, the foregoing description only is for the utility model example clearly is described, and is not the qualification to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being extended out thus or change still are among the protection domain of the present utility model.
