Even.
The ash dropping hopper upper end edge flue gas flow direction direction both sides are provided with preceding brick baffle and rear brick baffle, described vertical heated
Facial canal is arranged between preceding brick baffle and rear brick baffle, is every on smoke-box, preceding brick baffle between preceding brick baffle and rear brick baffle
Upper end smoke inlet is provided between end and furnace wall ceiling, rear brick baffle lower end is provided with horizontal lower end outlet flue.
As a kind of preferred scheme, vertical heating surface pipe described in the utility model is six；Six vertical heating surface tubes
Sub in parallel, upper and lower side links together；Six vertical heating surface pipes are divided into three groups, every group of two vertical heating surface tubes, three groups
Vertical heating surface pipe is sequentially arranged along flue gas flow direction direction, and every group two vertical heating surface tubes are horizontal along vertical flue gas flow direction direction
To arrangement.
The utility model beneficial effect.
After the utility model, the flue dust for being brought to back-end surfaces is greatly reduced, and the abrasion of boiler reduces, pipe
The service life of son significantly improves, and ensures boiler safety reliability service.And because afterbody pipe dust stratification is reduced, heat-transfer effect is not
It can substantially be reduced with the increase using the time, save mass energy.
Using before this utility model, wasted time and energy because tube wear retubes, clears up tube wall dust stratification, and workload
Greatly, after using this utility model, workload greatly reduces, and has saved a large amount of maintenance costs.
The utility model can be applicable in a variety of type of furnaces, with the investment of very little, solve boiler manfacturing and fortune for a long time
Row enterprise is for the excessive puzzlement of boiler tail dust stratification.
The utility model, which is set, overhauls the maintenance deashing that deashing fire door is easy to associated components.
Laterally snakelike roof tube is provided with above the utility model ash dropping hopper Keep away from boiler upper collecting chamber side；Ash dropping hopper is remote
Top from boiler upper collecting chamber side is the high-temperature area in furnace wall, sets laterally snakelike roof tube here, is easy to horizontal snake
Liquid in shape roof tube preferably absorbs heat.
Ash dropping hopper is provided with heated coiled pipe in the furnace wall on the outside of the ash dropping hopper of boiler upper collecting chamber side, is easy to absorb warp
The heat of flue gas after vertical heating surface pipe is crossed, reduces exhaust gas temperature.
When brick baffle enters every smoke-box before flue gas flows through, the actual internal area of flue gas becomes big suddenly, and dust moves in flue gas
It can die down, the dust of larger particles is because in Action of Gravity Field meeting ash dropping hopper, a part of dust is due to the stop of outlet smokestack tube
Fall into ash dropping hopper, some flue dust is beaten on rear brick baffle, is also fallen into ash dropping hopper, and is drained into by ash tube outside boiler
Portion, most of flue dust can be stopped by installing this device, allowed flue dust to be separated in boiler internal by primary, prevented volume of smoke from flowing to tail
In portion's heating surface, the fume amount into boiler tail is reduced, to reduce the abrasion to back-end surfaces.
