The technical solution of the utility model is:A kind of high efficiency burnt gas large-tonnage water pipe steam boiler, including upper drum is with Drum, water-cooling system, energy-saving appliance, platform staircase, insulation guard board, combustion system and control system, upper drum and lower drum it is longitudinal, Water-cooling system includes fin panel casing tube bank, convection bank, and before burner hearth and both sides are provided with fin panel casing tube bank, convection bank Between upper and lower drum, convection bank upper/lower terminal is welded respectively in-line arrangement with upper and lower drum, and energy-saving appliance is arranged in boiler Body left side, is connected by flue with boiler body, and energy-saving appliance heating surface adopts horizontally disposed coiled pipe, the horizontal cloth of combustion system Front wall is placed in, boiler body is provided with peep hole, explosion proof door, is provided with built-in explosion proof door after boiler body in smoke box, burner hearth goes out Mouth and energy-saving appliance outlet set flue-gas temperature measuring point, and main steam mouth and energy-saving appliance are imported and exported and set vapor (steam) temperature, water temperature measuring point, burning system System is connected with control system.
The convection bank adopts the steel pipes of Φ 51 × 3.
The energy-saving appliance adopts the coiled pipes of Φ 32 × 3.
The beneficial effects of the utility model are:The utility model is burnt the high temperature of generation by gas burner in burner hearth Flue gas, point or so enter boiler rear portion in-line convection bank evaporating heating surface, to ensure that flue gas uniformly washes away the upper lower drum of connection The steel pipes of Φ 51 × 3, by Natural Circulation heat exchange mode, then energy-saving appliance is entered by boiler front portion flue, energy-saving appliance is adopted The horizontally disposed snake-like tube row groups of Φ 32 × 3, by 104 DEG C of feedwater heating upper drum is entered, and overall package is finished in its factory, existing Field is mounted directly, and energy-saving appliance adopts two backhaul heat exchange modes to ensure maximum heat transfer effect, and flue gas out enters cigarette by flue Chimney is discharged.The environmental-protecting performance of national standard is met and exceeded, it is energy-efficient, the steam boiler of generating set is suitable for, especially fire Burn the big specification water pipe steam boiler of the fuel such as natural gas, light diesel fuel or town gas.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
From structural representation of the present utility model shown in Fig. 1 the utility model is can be seen that by by upper drum 1 and lower drum 8th, the composition such as water-cooling system 2, energy-saving appliance 5, platform staircase 7, insulation guard board 3, combustion system 4, control system and annex, using upper Drum 1 and the longitudinal water pipe D-shaped arrangement of lower drum 8, water-cooling system 2 includes fin panel casing tube bank, convection bank, before burner hearth Face and both sides be provided with fin panel casing tube bank, convection bank in-line arrangement between upper and lower drum, convection bank upper/lower terminal Weld with upper and lower drum respectively, energy-saving appliance 5 is arranged in boiler body left side, is connected with boiler body by flue, energy-saving appliance 5 Heating surface adopts horizontally disposed coiled pipe, and combustion system 4 is horizontally disposed in front wall, and boiler body is provided with peep hole, explosion proof door, Built-in explosion proof door is provided with after boiler body in smoke box, furnace outlet and the outlet of energy-saving appliance 5 set flue-gas temperature measuring point, main steam mouth And energy-saving appliance 5 is imported and exported and sets vapor (steam) temperature, water temperature measuring point, combustion system 4 is connected with control system.Upper drum 1 and lower drum 8 are equal Rolled with Q245R/GB713 steel plates and formed.Upper drum 1 is equipped with a set of water level equalizing reservoir and electric contact water gage, double-colored water Position table is each two sets, and arranges the bases such as continuous blowdown, stove water sampling.One spring safety valve, pressure gauge are housed on upper drum 1; It is also equipped with personal steam base etc..Ordinary water level 100mm under drum center line.Baffle plate, water are disposed with inside upper drum 1 Orifice plate first separation element, and corrugated sheet, Perforated plate secondary separate component.The inside of lower drum 8 is equipped with blow-off pipe.For ease of Maintenance internal unit, upper and lower drum internal unit is mainly connected by screw bolt and nut.Water-cooling system is arranged in upper and lower drum Between, it is made up of the steel pipe in-line arrangements of Φ 51 × 3, upper/lower terminal is welded with upper and lower drum, and tubing is 20/GB3087. Energy-saving appliance 5 adopts the coiled pipes of Φ 32 × 3, and material is 20/GB3087.Combustion system 4 adopts leading brand burner, burner to match somebody with somebody Put program controlled automatic ignition installation, and flame-out protection device.This boiler is every need frequent operation, monitoring, maintenance and equipped with aperture of door, Valve, peep hole, water gage, main steam safety valve etc. are equipped with platform staircase 7.Boiler body is rested on bottom support bracket, whole The surrounding of individual boiler is coated by insulation guard board 3.
