Description
Technical field
The utility model relates to a kind of assembling chain grate boiler.
Background technology
The assembling chain grate boiler divides two big part assemblings, and top is boiler body, comprises burner hearth, convection bank etc., the bottom is the traveling-grate stoker part, comprise coal bunker, traveling-grate stoker etc., after two big parts are assembled on-site, carry out to come into operation after necessary furnace wall, the pipeline installation.Big of boiler body of semi-packaged boiler and traveling-grate stoker are after the building site closes up at present, only need to build by laying bricks or stones part furnace wall and chimney arch, forward and backward chimney arch at the scene according to the requirement of design coal with refractory brick or the curved arching building of refractory concrete on fire grate top, be supported on the fire grate both sides, wall is built by laying bricks or stones on rear arch with refractory brick behind the burner hearth.And chimney arch is the key position that influences fuel fire, this furnace arch structure is not arranged heating surface because of lower furnace portion, the high temperature that coal combustion produces can not get timely absorption, and lower furnace portion high temperature damages front and back arch exit burning even caves in, and need regularly repair and overhaul.Being arranged in of arch is subjected to the constraint that arc encircles to a certain extent on the other hand, and be relatively poor to the adaptability of coal, influences the efficient of boiler.
Summary of the invention
The utility model is for the chimney arch rapid wear that the solves traditional semi-packaged boiler problem of easily collapsing, and provides a kind of thermal efficiency higher semi-packaged boiler.
For achieving the above object, the utility model adopts following technical scheme: a kind of semi-packaged boiler, its top is the boiler body that comprises that drum, convection bank and burner hearth are formed, the bottom comprises coal bunker and traveling-grate stoker, burner hearth front side bottom is provided with front header, and traveling-grate stoker afterbody top is provided with back header, is connected preceding water-cooling wall between described front header and the upper drum, be connected the back water-cooling wall between described back header and the upper drum, back water-cooling wall bottom is turned then behind stove to the burner hearth intermediate projections and is linked with back header.
Water-cooling wall and water-cooling wall bottom, back all are wrapped with the uniform refractory material of a layer thickness and form preceding chimney arch and back chimney arch respectively before described.
Water-cooling wall upper end, described back is welded in the upper drum, the last flex point place that extends downwardly into the mid point ± 300mm of upper drum center line and interface distance folds to the stokehold forward down, rolls over back header to the oblique back, following flex point place of below, composition surface 200mm～300mm to weld together.
Adopt technical scheme described in the utility model, because front header is moved down into bottom, burner hearth front side, traveling-grate stoker afterbody top is provided with back header, chimney arch is that to make skeleton with water screen tube evenly distributed, has increased the intensity of chimney arch, has increased heating surface and the easier reasonable Arrangement of chimney arch on the other hand on fire grate top, make the high temperature on siege top be absorbed, reduced the chimney arch outlet temperature, the thermal efficiency of boiler is higher, and prevents the chimney arch damage effectively and cave in.
Description of drawings
Figure 1 shows that the general assembly subdivision structural representation of traditional semi-packaged boiler;
Fig. 2 is the utility model general assembly subdivision structural representation.
The specific embodiment
As shown in Figure 1, the top of tradition semi-packaged boiler is the boiler body that comprises that upper drum 4, lower drum 11, convection bank 12 and burner hearth 8 are formed, the bottom comprises coal bunker 2 and traveling-grate stoker 1, coal bunker 2 is positioned at furnace wall traveling-grate stoker 1 top, the afterbody boiler bottom surface of traveling-grate stoker 1 has cinder notch 3, front header 16 is positioned at the bottom of composition surface 18 top burner hearths 8, be connected between the upper drum 4 before water-cooling wall 5 and preceding down-comer 6.After upper and lower two big parts close up on-site, need build back wall 7 and preceding chimney arch 9, back chimney arch 10 by laying bricks or stones, before chimney arch 9, back chimney arch 10 at the scene according to the requirement of design coal with refractory brick or the curved arching building of refractory concrete on fire grate 1 top, be supported on fire grate 1 both sides, wall 7 usefulness refractory brick are built by laying bricks or stones on the chimney arch 10 of back behind the burner hearth.Chimney arch is the key position that influences fuel fire, this furnace arch structure is not arranged heating surface because of lower furnace portion, the high temperature that coal combustion produces can not get timely absorption, and burner hearth 8 bottom high temperature damage 9, the 10 exit burning of front and back arch even cave in, and need regularly repair and overhaul.Being arranged in of arch 9,10 is subjected to the constraint that arc encircles to a certain extent on the other hand, and be relatively poor to the adaptability of coal, influences the efficient of boiler.
As shown in Figure 2, the top of the utility model semi-packaged boiler is the boiler body that comprises that upper drum 4, lower drum 11, convection bank 12 and burner hearth 8 are formed, the bottom comprises coal bunker 2 and traveling-grate stoker 1, coal bunker 2 is positioned at furnace wall traveling-grate stoker 1 top, the intermediate arrangement of traveling-grate stoker 1 has some air channels 17, the afterbody boiler bottom surface of traveling-grate stoker 1 has cinder notch 3, front header 16 is positioned at 18 belows, composition surface, bottom, burner hearth 8 front sides, traveling-grate stoker 1 afterbody top is provided with back header 14, and front header 16 and back header 14 all are fixed on the traveling-grate stoker support.Water-cooling wall 5 and preceding down-comer 6 before being connected between front header 16 and the upper drum 4, be connected back down-comer 15 between back header 14 and the lower drum 11, with be connected between the upper drum 4 back water-cooling wall 13, back water-cooling wall 13 upper ends are welded in the upper drum 4, last flex point 19 places that extend downwardly into the mid point ± 300mm of upper drum 4 center lines and composition surface 18 distances fold to the stokehold forward down, and oblique back, following flex point 20 places of 18 below 200mm～300mm folding welds together with back header 14 to the composition surface.The particular location of last flex point 19 and following flex point 20 will be according to using the different of coal to adjust.Burner hearth 8 rear walls need be built back wall 7 by laying bricks or stones, and preceding water-cooling wall 5 and water-cooling wall 13 bottoms, back all are wrapped with the uniform refractory material of a layer thickness and form preceding chimney arch 9 and back chimney arch 10 respectively.
Coal-fired coal bunker 2 by the front portion falls into fire grate 1 front end, falls into cinder notch 3 and discharged by mucking machine after burning.Air 17 enters fire grate 1 bottom subregion and enters siege from the air channel, and the coal-fired high-temperature flue gas that produces in burning back on the grate enters atmosphere by dedusting behind burner hearth 8 convection tubes 12 heating surfaces such as grade.Water carries out Natural Circulation in boiler body after entering upper drum 4 after the back-end surfaces preheating.
The chimney arch of improved the utility model semi-packaged boiler is that to make skeleton with water screen tube evenly distributed, increased the intensity of chimney arch, heating surface and the easier reasonable Arrangement of chimney arch have been increased on the other hand on fire grate 1 top, make the high temperature on siege top be absorbed, reduced the temperature of chimney arch outlet, the thermal efficiency of boiler is higher, and can prevent the chimney arch damage effectively and cave in.
