Abstract
A coal water slurry or peat slurry boiler with covering grate and ash bucket is characterized in that: two side walls of the anterior boiler and the ceiling of the boiler tube is wrapped by refractories, the bottom of the stable combustion chamber is a grate(that is boiler bottom) which is formed by multi-group boiler tubes wrapped by refractories, a shutter plate whose surface has refractories is provided under the grate, thus the front of the boiler forms a coal water slurry stable combustion chamber, the lower thereof is provided with the ash bucket and a mechanical slag remover; at the bottom of the later part of the boiler combustion chamber, every few boiler tubes is staggered with one or two boiler tubes to allow some space, so the ash can drop into the lower ash bucket through the space. The coal water slurry or peat slurry boiler with the above structure can meet the continuous operation needs of Industrial and mining enterprises and civil heating.
Description
Technical field:
It is industry or the civilian steam or the hot-water boiler of fuel that the utility model belongs to water-coal-slurry or mud coal slurry.
Background technology:
Water-coal-slurry is a kind of novel coal based fluid fuel, has the pipeline transportation of being easy to, be convenient to loading and unloading, store and oligosaprobic characteristics, the coal-water fluid burner that the researcher has developed multiple pattern uses water-coal-slurry, wherein be mostly large-scale be to use on the boiler of fuel with the coal dust, coal water slurry boiler in industry and civil area application, also do not have a kind ofly can satisfy continuous service requirement, what wherein mainly need solution is the problem of ash disposal and slagging-off, this coal water slurry boiler is to pass through optimization, design on the basis of improvement oil burning boiler integral layout and structure, it has solved effectively because the dust stratification of boiler, the boiler that reasons such as slagging scorification cause is forced to the stoppage in transit problem.Its primary structure is: the two side of boiler front end and the boiler tube of ceiling coat with refractory material, the stable burning room bottom is the fire grate (fire grate is furnace bottom just) that is formed by the many groups of boiler tubes that coat with refractory material, the shadow shield of a surface with refractory material is set below fire grate, thereby the front end at boiler forms water-coal-slurry stable burning room, and its below is for receiving grey slag bucket and mechanical device for dragging dregs; In the latter half of furnace bottom part of boiler furnace, every one of several boiler tube stagger arrangement or two, reserve certain interval, make that the ash through burning falls in the receipts ash bucket of below by this gap.The coal water slurry boiler of this kind structure have compact conformation, reliable, ignition trigger fast, be easy to control and characteristics that efficiency of combustion is high, can satisfy industries such as industrial and mining enterprises and the civil heating demand of operation continuously.
Summary of the invention:
The technical solution of the utility model realizes by following manner:
This type boiler be a kind of be the hot water or the steam boiler of fuel with the water-coal-slurry, it is characterized in that in the bottom of coal water slurry boiler and afterbody convection bank, being provided with and receive ash and deslagging device, the boiler that is about to the boiler first half layout of having loose bowels, two side and ceiling coat fully with refractory material, per two or three of the boiler tube of bottom is one group, each is organized and leaves certain clearance between boiler tube, also it is coated with refractory material, can the fall fire grate (fire grate is furnace bottom just) of lime-ash of formation, the shadow shield of a surface with refractory material is set, the refractory wall of both sides below fire grate, ceiling and fire grate have been formed a water-coal-slurry stable burning room; At the latter half of boiler furnace, the boiler tube normal alignment at both sides and top, in the furnace bottom part, stagger arrangement is one or two about several boiler tubes, reserves certain interval, makes to fall in the receipts ash bucket by this gap through the ash that burns; Below receipts lime-ash device, be provided with the storage slag bucket and receive ash bucket; High temperature convective region and low temperature convective region in the afterbody convection bank respectively leave ash-removing hole, in order to the deashing and the maintenance of boiler when overhauling or after stopping transport.
For further openly the technical solution of the utility model, be further elaborated in conjunction with example below by accompanying drawing 1,2.
Description of drawings:
Fig. 1 is the side view of water-coal-slurry or mud coal slurry boiler.
Fig. 2 is the elevation of water-coal-slurry or mud coal slurry boiler.
The specific embodiment:
This type boiler is mainly by chain fortune slag remover 1, grey slag bucket 2, shadow shield 3, furnace bottom fire grate 4, water coal slurry burner 5, water-coal-slurry stable burning room 6, upper drum 7, lower drum 8, afterbody convection bank 9, explosion proof door 10, go out ash bucket 11, boiler foundation 12 constitutes.Burning carries out at first entering after secondary atomizes stable burning room's fire burns that suspending with water-coal-slurry through the slurry rifle, the latter half of of burner hearth is the burnt zone of water-coal-slurry, hot flue gas after the burning carries the part soot particle and enters the afterbody convection bank and carry out heat convection, the slag that forms in the water-coal-slurry stable burning room and the ash of another part larger particles then enter receipts slag ash bucket by the fire grate and the furnace bottom gap of furnace bottom, discharge through going out ash bucket by the mechanical deslagging machine again, thereby finish the combustion process of whole water-coal-slurry.
