Abstract
The invention provides a technical scheme of a horizontal boiler. The horizontal boiler comprises a boiler body, and a fire grate, a hearth, a water cooling wall and a horizontal drum in the boiler body. The horizontal drum is internally provided with a smoke tube. A front smoke box and a smoke exhaust channel are arranged outside the horizontal drum. The horizontal boiler is characterized in that the water cooling wall is formed by 1-5 water cooling wall pipes as a group and 1-5 convection tubes as a group at intervals. The convection tubes are parallel to the water cooling wall pipes on the lower part of the hearth, and are further communicated with the horizontal drum after being bended at an angle of a into the hearth on the middle and lower part of the hearth. The horizontal boiler is further characterized in that the bending angles a of each group of the convection tubes are different. The angle a is maximally 85 degrees and minimally 15 degrees.
Description
Technical field:
What the present invention relates to is a kind of boiler, especially a kind of horizontal boiler.
Background technology:
In the prior art, with the most approaching technical scheme of the application be horizontal boiler in usefulness, the water-cooling wall of conventional horizontal boiler all is made up of the water screen tube that a row is gathered, the effect of this water screen tube middle and lower part is obvious, and the effect of middle and upper part is not good enough.And conventional horizontal boiler is too high in the temperature of burner hearth rear portion and smoke pipe, and heat exchange area is not enough, causes the waste of mass energy, and this is the existing in prior technology weak point.
Summary of the invention:
Technical problem to be solved by this invention; Be exactly not enough to existing in prior technology; And provide a kind of technical scheme of horizontal boiler, this scheme to adopt and make the part water screen tube into convection tube, not only still play the effect of water-cooling wall; Also improve heat exchange area greatly, reduced the waste of the energy.
This programme is realized through following technical measures: horizontal boiler; Include fire grate, burner hearth, water-cooling wall and horizontal drum in body of heater and the body of heater; In horizontal drum, smoke pipe is arranged; Front smoke box and smokejack are arranged outside horizontal drum; The characteristics of this programme are that described water-cooling wall is that to be propped up by 1-5 be that one group water screen tube and 1-5 prop up be that one group convection tube space constitutes, and described convection tube is parallel with water screen tube in the bottom of burner hearth, and every group of convection tube in the middle and lower part of burner hearth in burner hearth behind the crooked a angle again with horizontal drum UNICOM.The concrete characteristics of this programme also have, and a angle of described every group of each canal curvature of convection tube is different.Described a angle is 85 degree angles to the maximum.Described a angle minimum is 15 degree angles.
The beneficial effect of this programme can be learnt according to the narration to such scheme; Because water-cooling wall in this scheme is that to be propped up by 1-5 be that one group water screen tube and 1-5 prop up be that one group convection tube space constitutes; Described convection tube is parallel with water screen tube in the bottom of burner hearth, and every group of convection tube in the middle and lower part of burner hearth in burner hearth behind the crooked different a angle again with horizontal drum UNICOM.This structure makes that the part water screen tube becomes convection tube in the water-cooling wall, and the effect of water screen tube is still played in the middle and lower part of these convection tubes; The middle and upper part of convection tube has then got in the burner hearth; Therefore, can absorb the heat of upper furnace, the heat exchange area of boiler is improved greatly; Also reduced simultaneously the temperature of burner hearth rear portion and smoke pipe, the thermal efficiency that has improved boiler has also reduced the consumption of the energy.This shows that the present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the part sectional structure sketch map of the specific embodiment of the invention.
Among the figure, 1 is fire grate, and 2 is burner hearth, and 3 is water screen tube, and 4 is the second backhaul smoke pipe, and 5 is the 3rd backhaul smoke pipe, and 6 is convection tube, and 7 is horizontal drum, and 8 is front smoke box, and 9 is body of heater.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme, below through a specific embodiment, and combine its accompanying drawing, this programme is set forth.
Can find out through accompanying drawing; The horizontal boiler of this programme is three return stroke horizontal boilers; Include fire grate 1, burner hearth 2, water-cooling wall and horizontal drum 7 in body of heater 9 and the body of heater 9; The second backhaul smoke pipe 4 and the 3rd backhaul smoke pipe 5 are arranged in horizontal drum 7; Outside horizontal drum 7, front smoke box 8 and smokejack are arranged, the described water-cooling wall of this programme is that to be propped up by 1-5 be that one group water screen tube 3 and 1-5 prop up be that one group convection tube 6 spaces constitute, and this specific embodiment is to adopt 4 to be one group water screen tube 3 and 3 convection tube 6 spaces formation water-cooling walls that are a group.Described convection tube 6 is parallel with water screen tube 3 in the bottom of burner hearth 2, and every group of convection tube in the middle and lower part of burner hearth 2 in burner hearth 2 behind the crooked a angle again with horizontal drum 7 UNICOMs.The a angle of described every group of convection tube 6 each canal curvature is different, and described a angle is 85 degree angles to the maximum, and minimum is 15 degree angles.In this specific embodiment every group the crooked a angles of 6, the first convection tubes of three convection tubes 6 are arranged is 85 degree angles, second convection tube 6 crooked a angle is 50 degree angles, the 3rd convection tube 6 crooked a angles are 20 degree angles.Three return stroke horizontal boilers of this structure; Make that part water screen tube 3 becomes convection tube 6 in the water-cooling wall, the effect of water screen tube 3 is still played in the bottom of these convection tubes 6, and the middle and lower part of convection tube 6 has then got in the burner hearth 2; Therefore; Can absorb the heat on burner hearth 2 tops, the heat exchange area of boiler is improved greatly, this specific embodiment can improve heat exchange area more than 40%; Also reduced simultaneously the temperature of burner hearth 2 rear portions and smoke pipe, the thermal efficiency that has improved boiler has also reduced the consumption of the energy.
The present invention is not limited in the above-mentioned specific embodiment, and the variation that those of ordinary skills make in essential scope of the present invention, remodeling, interpolation or replacement also should belong to protection scope of the present invention.
