Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming that above-mentioned old-fashioned fire tube boiler exists, and a kind of grate firing corner-tube hot-water boiler is provided.
The utility model is made up of traveling-grate stoker, face arch, furnace wall cooling, rear arch, drum, media outlet, crust block pipe, economizer, air preheater, flue outlet, safety attachment and coal bunker, and traveling-grate stoker is positioned at the bottom of body of heater, and coal bunker is positioned at traveling-grate stoker top; Body of heater inside has burner hearth, and the front portion of burner hearth is a face arch, and the rear portion is a rear arch; The sidewall of burner hearth is a furnace wall cooling, and the top of body of heater has drum and media outlet, is separated with back-end ductwork between the rear portion of burner hearth; Has the crust block pipe between the burner hearth at top and the back-end ductwork; Be provided with economizer in the back-end ductwork, be filled with medium in drum, furnace wall cooling and the economizer, furnace wall cooling and economizer are communicated with drum; Be provided with air preheater in the outside flue of body of heater, back-end ductwork is communicated with outside flue.
Described furnace wall cooling is a film water cold wall structure, and skin is backplate, interposition heat-insulation layer, and inside is water cooling tube.
Said economizer is for being flag formula heating surface.
Described traveling-grate stoker is not for leaking coal stove row.
The beneficial effect of the utility model is:
1, the foot of exerting oneself, stable, easy to adjust.
2, this boiler is cornue carriage posture structure, the film water cold wall structure of full welded closure, light-duty tubine insulation construction, forces water circulation structure, and radiation loss is little, and the thermal efficiency is high; Steel consumption is low, saves insulation material.
3, adopt the layering coal supply technology to reach and do not leak coal stove row, strengthen burning of coal, reduce ashpit losses, further improve boiler thermal output.
4, economizer adopts afterbody flag formula heating surface, configuration novel energy-conserving fire grate, sets up measure such as dedusting in stove, and environmental protection characteristic is good, floor space is little, installation period is short.
5, each parts has all adopted normal structure in the boiler design, and the generalization degree is high, has extremely strong interchangeability with other boilers.

The specific embodiment
See also illustrated in figures 1 and 2ly, be the embodiment of the utility model, it is made up of traveling-grate stoker 1, face arch 2, furnace wall cooling 3, rear arch 4, drum 6, media outlet 7, crust block pipe 8, economizer 9, air preheater 10, flue outlet 11, safety attachment 12 and coal bunker 15; Traveling-grate stoker 1 is positioned at the bottom of body of heater, and coal bunker 15 is positioned at traveling-grate stoker 1 top, and body of heater inside has burner hearth 13; The front portion of burner hearth 13 is a face arch 2, and the rear portion is a rear arch 4, and the sidewall of burner hearth 13 is a furnace wall cooling 3; The top of body of heater has drum 6 and media outlet 7; Be separated with back-end ductwork 14 between the rear portion of burner hearth 13, have crust block pipe 8 between the burner hearth 13 at top and the back-end ductwork 14, be provided with economizer 9 in the back-end ductwork 14; Be filled with medium in drum 6, furnace wall cooling 3 and the economizer 9; Furnace wall cooling 3 is communicated with drum 6 with economizer 9, is provided with air preheater 10 in the outside flue of body of heater, and back-end ductwork 14 is communicated with outside flue.
Described furnace wall cooling 3 is film water cold wall structures, and is as shown in Figure 4, and skin is backplate 31, interposition heat-insulation layer 32, and inside is water cooling tube 33.
Said economizer 9 is for being flag formula heating surface, and is as shown in Figure 5.
Described traveling-grate stoker 1 is not for leaking coal stove row.
The operation principle and the process of the utility model are:
1, flue gas flow: fuel gets into traveling-grate stoker 1 by coal bunker 15; Air gets into burner hearth 13 by the air channel, bottom through fire grate; Fuel burns on fire grate, and high-temperature flue gas upwards flow along face arch 2, rear arch 4 broken line directions in the burner hearth 13, the high-temperature flue gas of generation in burner hearth 13 radiation heat releases after crust block pipe 8 gets into back-end ductworks 14; After washing away economizer 9, air preheater 10, discharge body of heater through flue outlet 11.The flue gas that boiler is discharged purifies through deduster, arranges to atmosphere through chimney again.
