Abstract
The utility model provides a technical proposal of a low-pressure steam boiler. The utility model mainly comprises a boiler base, a boiler body, a combustion chamber, a grate, an air supply hole, a coal-feeding pipe, a smoke pipe, a pressure gauge, an air outlet, a safety valve, a water-feeding pipe, and a water level gauge. The utility model is characterized in that a closed annular flue is arranged between the inner wall of the boiler body and the combustion chamber, the coal-feeding pipe is provided with a flue hole which is communicated with the annular flue, and the annular flue is provided with a plurality of vertical water pipes which are penetrated through the annular flue. The middle part of the inner cavity of the annular flue is provided with a partition board which is used for separating the annular flue into an upper and a lower two portions, the partition board is provided with a partition board orifice, and the smoke pipe is connected with the top of the annular flue.
Description
The utility model relates to a kind of boiler, especially a kind of low pressure steam boiler.
Existing steam boiler except that high pressure steam boiler, general in, low pressure steam boiler is eliminated mostly, its reason is exactly that efficient is too low, coal consumption is big and exert oneself little.
The purpose of this utility model is exactly at the existing in prior technology deficiency, and the low pressure steam boiler technical scheme of a kind of efficient height and province's coal is provided.
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
Description of drawings:
Fig. 1 is the part sectional structure schematic diagram of the utility model embodiment;
Fig. 2 is that the A-A of Fig. 1 is to cross-sectional schematic;
Fig. 3 is that the B-B of Fig. 1 is to cross-sectional schematic;
Fig. 4 is that the C-C of Fig. 1 is to cross-sectional schematic.
By accompanying drawing as can be seen, the low pressure steam boiler of this programme mainly includes Pressure gauge 8, gas outlet 9, safety valve 10, filler pipe 11, water level meter 12 on stove seat 1, body of heater 6, combustion chamber 5, fire grate 17, wind pushing hole 18, coal feeding pipe 3, smoke pipe 7 and the body of heater 6.The characteristics of this programme are the annular flues 15 that a closure is arranged between the inwall of described body of heater 6 and combustion chamber 5, and by hanger 16 supports, have floss hole 2 in the two side of described coal feeding pipe 3 at annular flue 15 places and communicate, on annular flue 15, also have a plurality of vertical water pipes 13 parallel to pass annular flue 15 with annular flue 15 axis with annular flue 15.Have the dividing plate 19 of a sealing that annular flue 15 is divided into two parts up and down at the middle part of annular flue 15 inner chambers, and have a dividing plate hole 14 on dividing plate 19, the position in described dividing plate hole 14 is the corresponding sides at coal feeding pipe 3.And in described combustion chamber 5, also have horizontal water tube 4 to pass combustion chamber 5.In addition, described smoke pipe 7 is to be connected with the top of annular flue 15, and its link position is the side at coal feeding pipe 3.
According to as can be known to the narration of such scheme, because there is the existence of annular flue the inside of body of heater in this scheme, flame in the combustion chamber is discharged by smoke pipe through behind the annular flue again, because annular flue is divided into upper and lower two parts by dividing plate, the length of this flue that just extended, the time lengthening that the heat of burning is retained in stove.And annular flue around and all being in the heated water on every side of combustion chamber, in addition, in the annular flue vertical water pipe is arranged again, and horizontal water tube is arranged in the combustion chamber, this has increased the heating surface area that is heated water greatly and has been heated water circulation quickly in body of heater with impelling, this can more help heat exchange, thereby has improved the efficient of boiler, has saved fire coal again.This shows that the utility model compared with prior art has substantive distinguishing features and progress, its implementation result also is conspicuous.
