Abstract
The utility model provides the technical scheme of a horizontal boiler which comprises a boiler body, a fire grate, a hearth, a water cooling wall and a horizontal boiler barrel, and the fire grate, the hearth, the water cooling wall and the horizontal boiler barrel are arranged in the boiler body; and a smoke pipe is arranged in the horizontal boiler barrel, and a front smoke box and a discharge flue are arranged outside the horizontal boiler barrel. The horizontal boiler is characterized in that the water cooling wall is formed by water cooling wall pipes and convection pipes mutually at intervals, one to five water cooling wall pipes are used as one group, and one to five convection pipes are used as one group, the convection pipes are arranged on the lower portion of the hearth and parallel to the water cooling wall pipes, the convection pipes bend towards the interior of the hearth from the middle lower portion of the hearth, the bending angle is a, and then the convection pipes are communicated with the horizontal boiler barrel. The horizontal boiler is further characterized in that each pipe in each group of convection pipes is different from one another in the bending angle a, the biggest angle a is 85 degrees, and the smallest angle a is 15 degrees.
Description
Technical field:
The utility model relates to a kind of boiler, especially a kind of horizontal boiler.
Background technology:
In the prior art, the technical scheme that approaches the most with the application is the horizontal boiler in usefulness, and the water-cooling wall of conventional horizontal boiler all is comprised of the water screen tube that a row is gathered, and 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 at the excess 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 weak point of prior art.
Summary of the invention:
Technical problem to be solved in the utility model, be exactly for the existing deficiency of prior art, and provide a kind of technical scheme of horizontal boiler, this scheme adopts and makes the part water screen tube into convection tube, not only still play the effect of water-cooling wall, also greatly improve heat exchange area, reduced the waste of the energy.
This programme is achieved by the 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 consists of, 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 the burner hearth behind the crooked a angle again with horizontal drum UNICOM.The concrete characteristics of this programme also have, and a angle that each pipe of described every group of convection tube is crooked 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 consists of, 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 the burner hearth behind the crooked different a angle again with horizontal drum UNICOM.This structure, so that the part water screen tube becomes convection tube in the water-cooling wall, 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 entered 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 utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is apparent.
Description of drawings:
Fig. 1 is the part sectional structure schematic diagram of the utility model specific embodiment.
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 by a specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
Can find out by 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 consist of, and this specific embodiment is to adopt 4 to be that water screen tube 3 and 3 convection tube 6 spaces that are a group of one group consist of water-cooling walls.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 behind the burner hearth 2 interior crooked a angles again with horizontal drum 7 UNICOMs.The a angle that described every group of convection tube 6 each pipe are crooked is different, and described a angle is 85 degree angles to the maximum, and minimum is 15 degree angles.Every group of a angle that 6, the first convection tube 6 bendings of three convection tubes are arranged is 85 degree angles in this specific embodiment, and a angle of second convection tube 6 bending is 50 degree angles, and a angle of the 3rd convection tube 6 bendings is 20 degree angles.Three return stroke horizontal boilers of this structure, so 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, the middle and upper part of convection tube 6 has then entered 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.
