The heating boiler has the advantages that the design is reasonable, the heat efficiency is high, the burning is sufficient, the fuel is saved, the coal used by the heating boiler is saved by 70% compared with the coal used by a civil boiler, and the discharge amount reaches the standard, so that the heating boiler is beneficial to environmental protection.

Description

The high-efficient energy-saving environment friendly heating boiler

Technical field the utility model relates to a kind of civil boiler, is a kind of energy-efficient heating boiler specifically.

The present general burner hearth of heating boiler of background technology is bigger, fills out more a large amount of coals, because its structure is unreasonable; Can not fully burn, it is transversely arranged mostly heat-exchange tube is, unfavorable to discharging fume; The draft of flue is little, is difficult for forming the big intensity of a fire, is unfavorable for abundant burning; Therefore the thermal efficiency is low, waste fuel, also contaminated environment.The hearth water sleeve design that has is unreasonable, and quick heating causes the high expansion of air pressure or burns out the partial hearth inwall.Horizontal, the oblique or screw arrangement of heat-exchange tube makes the circuitous discharging of pyrotechnics slow, manages outer wall hanging cigarette You, influences heat exchange, also influences boiler service life.

The purpose of summary of the invention the utility model is to provide a kind of high-efficient energy-saving environment friendly heating boiler, its sufficient combustion, and the thermal efficiency is high, energy-conserving and environment-protective.

The technical scheme of the utility model is following:

This device is by body of heater, burner hearth, grey chamber, flue; Water jacket, heat-exchange tube and return pipe, delivery port constitute, and above-mentioned body of heater has the big trapezoidal burner hearth in little top, bottom; It between body of heater and the burner hearth water jacket; Establish the bell of band water jacket on the burner hearth, the fire grate of burner hearth is grey chamber, body of heater peripheral hardware one lower water box down; Burner hearth one side connects flue, connects flue dust under the flue and falls to struggling against, and lays the heat-exchange tube of a plurality of vertical arrangements in the flue; The water jacket UNICOM of this pipe and flue, hot water outlet pipe, air bleeding valve are established in flue top, and the body of heater bottom has return pipe to connect lower water box; This water tank connects water jacket, and drain valve is established in its underpart.

Above-mentioned grey chamber area is 4-6 a times of grate area.

The volume of above-mentioned flue is 16～18 times of combustion space.

Above-mentioned flue is established inspection socket.

The water jacket of above-mentioned bell connects the flue water jacket through flexible pipe, also has return pipe to connect furnace water jacket.

The advantage of the utility model is: 1, the thermal efficiency is high, sufficient combustion, fuel savings; Economize on coal 70% than general civil boiler, since the trapezoidal burner hearth of this warming stove, following little going up greatly; The ash chamber is big, and the wind that is advanced is compressed at the fire grate place, and flow velocity is fast, help abundant burning; The vertical flue that burned flame, flue gas get into through short bend again, the vertical heat-exchange tube of this flue institute cloth is discharged favourable smoothly to cigarette, and it is combustion-supporting to form big draft.2, vertical heat-exchange tube helps the water circulation, and water is heated upwards, rises fast than laterally reaching spiral stringing hot water; Make boiler after filling out coal, produce hot water rapidly; Can comparatively fast heat radiator, make the room quick heating, in two hours, fill out 5 dants; 600～800 grams/inferior just can make 200 kg of water be heated to 80～100 degree.Hot water rises fast and produces part steam, and pressure is high, can be with three layers of Automatic Cycle of civic building.3, burner hearth inverted trapezoidal structure makes the outer bottom of burner hearth water jacket thicker, and it is overheated to be difficult for, and the steam of generation is also few, and unlikely air pressure height expands or burns out the partial hearth inwall, makes this warming stove long service life.4, set lower water box makes direct water receiving cover of return pipe, and the water temperature of return pipe is low, and is slow like the circulation of water receiving cover, adds lower water box return water temperature is increased, and gets into water jacket again.5, sufficient combustion, carbon dioxide, the sulfur dioxide arranged are up to standard, reduce the Yan You and hang heat-exchange tube, and help environmental protection.6, this warming stove is opened bell and can be heated up water, cook, and is fit to family and uses.

Description of drawings Fig. 1 is the utility model overall structure generalized section;

Fig. 2 is that A-A is to view.

The specific embodiment is described further the utility model below in conjunction with accompanying drawing.

Can see that by Fig. 1-2 this device is by body of heater 7, burner hearth 14, grey chamber 13, flue 4, water jacket; Heat-exchange tube 16 and return pipe 12, delivery port 17 constitute; Above-mentioned body of heater has the big trapezoidal burner hearth 14 in little top, bottom, is water jacket 10 between body of heater and the burner hearth, establishes the bell 6 of band water jacket on the burner hearth; The fire grate of burner hearth is for 8 times grey chamber 13, and the area of bottom, grey chamber is 6 times of fire grate; Burner hearth one side connects flue 4, connects flue dust under the flue and falls to struggling against 15, and the flue volume is 16 times of combustion space; Lay the heat-exchange tube 16 of a plurality of vertical arrangements in the flue, water jacket 2 UNICOMs of this pipe and flue, hot water outlet pipe 17, air bleeding valve 18 are established in flue top; Inspection socket 3,1st, exhaust opening are established in the flue middle part; Lower water box 9 is arranged at the body of heater bottom, its water pipe 12 that is linked back; The water jacket of above-mentioned bell connects the flue water jacket through flexible pipe 5, also has return pipe 11 to connect furnace water jacket.The 19th, the lower water box drain valve.
