The W flame boiler comprises a boiler body, a plurality of longitudinal clapboards, a plurality of transverse flow guide plates, at least two rows of steam branch pipes, a plurality of ash blowing spray nozzles and a temperature measuring device, wherein the ash blowing spray nozzles are communicated with the steam branch pipes; an area between each pair of longitudinal clapboards forms an air separating chamber; the transverse flow guide plates are arranged in each air separating chamber from top to bottom in parallel; a plurality of ash removal pores are formed on each transverse flow guide plate; the temperature measuring device is a thermoelectric couple and arranged nearby a water cooled wall gap of the boiler; a steam ash blowing branch pipe is arranged outside a boiler arch slope of the boiler body and is provided with the ash blowing spray nozzle; and the ash blowing spray nozzle passes through the position of a water-cooled wall and is sealed in a welding manner. The W flame boiler has the positive effects that the problem that a large amount of ash is accumulated at the boiler arch slope of the boiler is solved, the combustion stability in the boiler is improved, and instable combustion in the boiler, even fire extinction caused by large-area cross ash at a boiler arch, is prevented.
Description
Technical field
The utility model relates to a kind of W flame boiler, particularly a kind of W flame boiler that has dusting function.
Background technology
The structure of Whostlfree spatial mode flame boiler is different with conventional coal-burning boiler; Its combustion chamber is made up of the combustion chamber of bottom and the secondary furnace on top, and the depth ratio secondary furnace of combustion chamber is big by 80～120, and the top of front ledge constitutes donor; Breeze airflow and overfire air jet are installed on the donor; Stretch downwards the breeze airflow of the following spray back that catches fire, and turning back after meeting with tertiary air in the bottom, combustion chamber makes progress, along rising on the furnace chamber axis; Thereby form W type flame, the combustion product air-flow rises and gets into secondary furnace.
But in practical engineering application, fouling phenomenon is very serious on the interior laterally deflector of separating chamber.Because the existence of dust stratification, the resistance of secondary air box will increase greatly.Simultaneously, dust stratification makes the secondary air channel between the adjacent transverse deflector become irregular, and secondary wind need be passed through the stream of turning back and unite could get into burner hearth.Turning back and system flows through in the journey, the original direct of travel of secondary wind can't be held, and tilt angled down can't be guaranteed, makes between secondary wind angle and the expection angle value of actual arrival burner hearth deviation to occur.
The utility model content
The utility model technical problem to be solved provides a kind of W flame boiler that has dusting function.
For solving the problems of the technologies described above; The utility model is realized as follows: a kind of W flame boiler that has dusting function comprises a plurality of grey nozzle and temperature measuring equipments of blowing that boiler body, a plurality of midfeather, a plurality of horizontal deflector, at least two are arranged steam branch pipes, communicated with steam branch pipe; Zone between said every pair of midfeather promptly constitutes a separating chamber, is arranged with said horizontal deflector in each said separating chamber from top to bottom in parallel, is furnished with a plurality of ash disposal holes on the said horizontal deflector; Said temperature measuring equipment is a thermocouple; Be arranged near the boiler water wall gap; Said steam soot blowing arm is arranged in the outside on said boiler body furnace arch, furnace nose slope, at said steam soot blowing arm the said grey nozzle that blows is set, and saidly blows the position that grey nozzle passes water-cooling wall and adopts the welding manner sealing.
The good effect of the utility model is: less for the nozzle area coverage that overcomes prior art, purge the defective that effect causes damage incessantly and to water screen tube; Provide that a kind of to blow grey nozzle area coverage big; It is good to purge the dust effect, and can protect the local soot blower of W flame boiler of water screen tube, and the utility model solves the problem that a large amount of dust stratifications are located on boiler furnace arch, furnace nose slope; Improve boiler combustion stability, prevent that striding ash because of furnace arch, furnace nose place large tracts of land causes the unstable even fire extinguishing of boiler combustion.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
The described a kind of W flame boiler that has dusting function of the utility model comprises a plurality of grey nozzle and temperature measuring equipments of blowing that boiler body 1, a plurality of midfeather 2, a plurality of horizontal deflector 3, at least two are arranged steam branch pipes, communicated with steam branch pipe.A plurality of midfeathers 2 are arranged on respectively on the front wall 1-1 and back wall 1-2 of boiler body 1 in couples; Zone between the every pair of midfeather 2 promptly constitutes a separating chamber 4; Following secondary air duct 6 is communicated with the burner hearth 1-3 of boiler body 1 through each separating chamber 4; Be arranged with horizontal deflector 3 in each separating chamber 4 from top to bottom in parallel, and horizontal deflector 3 is near the downward-sloping setting of an end of burner hearth 1-3; Be furnished with a plurality of ash disposal hole 3-1 on each horizontal deflector 3.
The water screen tube outer wall of one end of the midfeather 2 described in this embodiment and 7 both sides, water-cooling wall gap is affixed; Said water-cooling wall gap 7 is formed by water screen tube layback or post-tensioning, and the zone that two midfeathers 2 of each 7 both sides, water-cooling wall gap surround constitutes a separating chamber 4; In addition, the spacing between the every pair of midfeather 2 can not wait setting, forms wide separating chamber and narrow separating chamber.
Temperature measuring equipment is a thermocouple; Be arranged near the boiler water wall gap 7; The steam soot blowing arm is arranged in the outside on boiler body 1 furnace arch, furnace nose slope; A plurality of grey nozzles 8 that blow are set the zone (generally being zone) of dust stratification easily in bottom, furnace arch, furnace nose slope, blow the position employing welding manner sealing that grey nozzle 8 passes water-cooling wall near boiler body 1 center.Blowing grey nozzle 8 is connected with the steam soot blowing arm is airtight.The blowing medium pipeline supports through suspension and support.
Blow grey nozzle 8 and be provided with perforate, the high speed blowing medium carries out disturbance from the perforate ejection of blowing grey nozzle 8 to dust stratification.The perforate of blowing grey nozzle 8 is blown the outside of the blowing medium arrival end of grey nozzle 8 on the furnace arch, furnace nose slope on a plurality of horizontal deflector 3 of boiler body 1.A plurality of arranged direction of blowing grey nozzle are vertical with bottom surface, furnace arch, furnace nose slope, and the blowing medium emission direction is parallel with bottom surface, furnace arch, furnace nose slope to reduce the wearing and tearing to water screen tube.Blow grey nozzle 8 perforates and be designed to the flat shape of dispersing, make the spout air-flow that certain grey area coverage of blowing arranged
When using this device, from the steam soot blowing arm, introduce one steam and blow out by blowing in the grey nozzle 8, the dust stratification fluidisation is got up, flying dust is carried under the disturbance of flue gas, solves place, furnace arch, furnace nose slope dust stratification and piles up problem.
The hole of ash disposal described in this embodiment 3-1 is the hole of arbitrary shape.
