Abstract
The utility model relates to a boiler furnace structure of a coal vertical type boiler. The bottom of the boiler furnace consists of a semicircular grate bars and a bearing plate which are connected together, and the grate bars corresponds to a furnace arch to form longitudinal layered combustion chambers. The bearing plate is provided with a diversion fire-proof layer attached on the furnace body, and the channel between the fire-proof layer and the furnace arch forms a fire chamber, and a secondary air supply pipe is arranged in the diversion fire-proof layer. The utility model reforms the existing furnace structure with manual poking of dry distillation reverse burning and lateral distribution, thoroughly solves the lamp black phenomena during the poking process and the coaling process, obviously improves the boiler furnace temperature, and correspondingly improves the thermal efficiency of the vertical type boiler.
Description
The utility model belongs to coal-burning boiler, relates to a kind of chamber structure of vertical fire coal multipurpose boiler.
The chamber structure of vertical fire coal boiler adopts the version of the anti-burning technology of destructive distillation mostly at present, and it is that the stove baking is that the boundary is divided into destructive distillation chamber and secondary combustion chamber with burner hearth with brick baffle, and the secondary wind inleting tube of once-through boiler outside is set on secondary combustion chamber top.The coal seam of destructive distillation chamber is divided into the fire bed of bottom and the destructive distillation floor on top, and the coal seam of secondary combustion chamber grate then is the fixed carbon burning zone of being dialled in by the destructive distillation chamber after destructive distillation.The vertical boiler of the above-mentioned chamber structure form of practice explanation exists the major defect of discharging black smoke.It is caused by following reason: one, and the fixed carbon burning zone destructive distillation of dialling in secondary combustion chamber from the destructive distillation chamber at any time is insufficient and have black coal, and operation rules is strict with and is dialled in this layer should be the anthracite layer, is difficult to assurance yet be subjected to operating experience to limit its concrete operations.Therefore, enter secondary combustion chamber without the abundant black coal of destructive distillation and the black smoke phenomenon must occur.Its two, coal-fired fugitive constituent can not be fully burned and discharge with thermal current and produce black smoke in the coal operation, reflects that its fire box temperature is on the low side.
The purpose of this utility model provides a kind of a kind of chamber structure that can eliminate the vertical fire coal multipurpose boiler of black smoke phenomenon.
Comprise in the technical scheme of realization above-mentioned purpose that body of heater, fire door, grate, stove baking and secondary are to airduct, also have following structure: burner hearth bottom is provided with mutually semicircle grate and the supporting plate that is connected, and semicircle grate is corresponding with the stove baking and constitute and can hold the bottom and be surplus combustion layer, middle for fixed carbon fires layer, top is the longitudinal layered combustion chamber of destructive distillation layer.Semicircle supporting plate is provided with the water conservancy diversion flame retardant coating that depends on body of heater, and the passage that it and stove dry by the fire constitutes fiery chamber, is provided with secondary in the water conservancy diversion flame retardant coating and gives airduct, and each secondary air outlet is distributed in the top of water conservancy diversion flame retardant coating.
It is two-part dividing plate that the convergence part of said semicircle grate and supporting plate is provided with the packing of bottom of furnace body space, and the furnace body wall in space, supporting plate bottom side is provided with the blast pipe of bringing volume adjusting apparatus into.
Imbedded three times in the refractory material of said stove baking lower end and given airduct, its air outlet distributes towards fiery chamber and evenly, and air inlet is located at space, supporting plate bottom side.
Said water conservancy diversion flame retardant coating, the heat convection space of its upper port is provided with horizontal water tube, and this pipe and boiler water jacket join.
The utlity model has following outstanding advantage:
1. longitudinal layered combustion chamber is the innovation structure form of the anti-burning technology of a kind of destructive distillation, has changed existingly manually to poke fire, and the combustion system of cross direction profiles does not need manually to poke fire in combustion process, has therefore overcome the black smoke phenomenon because of improper generation on the opportunity of poking fire.
In adding the coal process its fugitive constituent kept off by the stove baking and under return the fixed carbon burning zone and in time burnt, after unburnt part enters fiery chamber, giving wind and three times to being able to abundant burning under the wind action through the secondary that gives heat, improved flame height and fire box temperature in the fiery chamber significantly, made later combustion process enter benign cycle.Not only solved the black smoke phenomenon in coal and the combustion process more up hill and dale, can also increase the heat-exchanger rig in heat convection space, the thermal efficiency of boiler is significantly improved.
3. testing its result through specialized department proves, adopting its smoke dust discharge concentration of vertical boiler of this chamber structure is 11.8mg/m
3, SO
2Concentration of emission is 173mg/m
3, be lower than 80mg/m respectively significantly
3And 500mg/m
3The provincial standard value.The result proves that also its lingemann blackness is less than one grade.The result proves through the thermal technology of specialized department index test, adopt the every index of vertical boiler thermal balance of this chamber structure all to be better than existing product, wherein thermal efficiency mean value reaches 75.35%, wherein appearance and size (φ * H unit: rice) be 0.8 * 2 tested stove its be 1111.16m for heating area
2(press 250.9KJ/m
2.h calculate) have a surplus for 1 times than existing same specification boiler increase.
Below in conjunction with drawings and Examples explanation the utility model.
Accompanying drawing 1 example structure generalized section
Embodiment as shown in the figure, the semicircle grate of burner hearth bottom is connected mutually with semicircle supporting plate 9, stove baking 2 is corresponding with semicircle grate and constitute longitudinal layered combustion chamber 4, it is highly decided on the boiler specification, and its height should satisfy each height sum of waste heat layer, fixed carbon burning zone, destructive distillation layer and combustion space, destructive distillation layer top.Supporting plate 9 is provided with the water conservancy diversion flame retardant coating 10 that depends on body of heater, and its surface has the inclined-plane of parabolic shape, and the passage between it and stove dry by the fire constitutes fiery chamber 11.Be provided with the secondary that constitutes by many vertical tubes in the water conservancy diversion flame retardant coating and give airduct 12, concentrate on water conservancy diversion flame retardant coating top respectively for a plurality of air outlets of airduct, secondary give airduct give heat through flame retardant coating for wind can obviously to improve fiery room temperature, in the heat proof material of stove baking lower end, also imbed simultaneously horizontal three times and give airduct 13, its air outlet distributes towards fiery chamber and evenly, and three times hot blast also gives heat through the stove baking.The two ends of giving airduct for three times are communicated with the space, bottom side of semicircle supporting plate 9 by vertical tube, and the furnace body wall in this space is provided with the blast pipe 8 of band windscreen 7, and windscreen can adjust two, the intake of tertiary air, and fire door 3 is located at the top side of longitudinal layered combustion chamber.
