The interior of a boiler hearth is provided with an inner boiler container which is communicated with the boiler body through an upper communicating pipe and a lower communicating pipe. The inner boiler container is provided with a plurality of smoke pipes which are communicated with the boiler hearth and a chimney. The boiler body is also provided with an ash cleaning door, hand holes, contamination discharge holes, etc. The utility model is convenient for repairing and improving the heat efficiency, and is suitable for supplying heat for common workers and inhabitant house buildings.

Description

The atmospheric vertical heating boiler

The utility model relates to a kind of normal pressure heating boiler.

Heating boiler in the market is of a great variety, but has the shortcoming of following several respects mostly:

1. in the radiation of burner hearth heat transfer zone, heating surface area is little, can not fully radiant heat be absorbed, and convection heating surface arranges that too much, structure is not compact, and the waste steel have reduced the thermal efficiency of boiler again.

2. the existing type of furnace is provided with horizontal water tube mostly, this horizontal water pipe water Cycle Difference, and easy scaling and blocking pipe causes the booster phenomenon, thus influence normal operation of boiler.

3. nobody's aperture apparatus, when boiler broke down, the staff can not enter in the stove and overhaul.

The purpose of this utility model provides a kind of radiant heat that can fully absorb improving the thermal efficiency, and is rational in infrastructure, save steel, be difficult for scaling, is convenient to the atmospheric vertical heating boiler of staff's maintenance.

The purpose of this utility model is achieved in that

A kind of atmospheric vertical heating boiler, comprise base, boiler body and chimney, boiler body is welded on the base, shoot door is arranged on the body, hand hole device and fire door, in the burner hearth of boiler body, inner furnace is arranged, inner furnace communicates with boiler body by several last communicating pipes and lower communicating tube, the position of hand hole in the lower communicating tube positive alignment boiler body, there are several smoke pipes to communicate in the inner furnace with burner hearth and chimney, smoke pipe is sent into the flue dust in the burner hearth in the chimney and with the water in the inner furnace and is heated, several heat pipes are evenly distributed on the inner furnace outside, and the heat pipe lower end acts on the inwall of boiler body.

Because the utility model is provided with inner furnace in burner hearth, several flues are arranged again in the inner furnace, has improved heating surface, has increased the thermal efficiency, has given up horizontal water tube, helps water circulation, and is less scaling, set up hand hole and manhole, easy access.

Provide an embodiment of the present utility model below in conjunction with accompanying drawing:

Fig. 1 is a structure cut-away view of the present utility model.

The atmospheric vertical heating boiler, comprise base 8, boiler body 4 and chimney 1, boiler body 4 is welded on the base 8, chimney 1 and atmospheric communicating pipe 2 are arranged at the top of body 4, on, there are outlet pipe 3 and water inlet pipe 9 in following two ends, blow-off pipe 7 is arranged at the bottom, also has shoot door 16 on the body 4, hand hole 11 and fire door 5, inner furnace 14 is arranged in the burner hearth 17, inner furnace 14 communicates with boiler body 4 by last communicating pipe 15 and lower communicating tube 10, the position of lower communicating tube 10 is over against hand hole 11, be provided with in several smoke pipes 12 and the burner hearth in the inner furnace 14 and chimney 1 communicates, smoke pipe 12 will the flue dust in the burner hearth 17 feeds in the chimney 1 and with the heating of the water in the inner furnace 14, several heat pipes 13 are evenly distributed on inner furnace 14 outsides, heat pipe 14 lower ends act on the inwall of boiler body 4, and shoot door 7 is arranged on the base 8.

Current enter boiler body 4 from water inlet pipe 9, inject inner furnace 14 through lower communicating tube 10, set up inner furnace 14, make high-temperature heating area increase in the burner hearth 17, several smoke pipes 8 are arranged again in the middle of the inner furnace 14, flame and flue dust in inner furnace 14 smoke pipe 8 and inner furnace 14 outside and pass through between boiler body 4 inwalls, directly increase heating surface area, improved the thermal efficiency, strengthened the heat exchange effect, reduced smoke density simultaneously, hand hole 11 is over against following runner pipe 10, and the incrustation scale that can in time remove in the inner furnace 14 is deposited slag, can make the water Natural Circulation in the inside and outside flue like this, promptly make things convenient for the staff to operate, prolonged the service life of stove again.Outer wall at inner furnace 14 has several heat pipes 13, heat pipe 13 lower ends act on the inwall of boiler body 4, promptly can conduct heat and can support the distortion that boiler body produces because of the pressurized that is heated, prevent to break, shoot door 4 is located at boiler body 4 tops, on the inner furnace 14, can remove the ash of depositing on inner furnace 14 tops so at any time, the staff also can enter the crock in the mediation smoke pipe 8 in the stove from here, check the scaling loss situation of stove, make things convenient for the maintenance at this position.

The utility model is used common sheet material more, has reduced the tubing consumption, has fallen at the end boiler cost, improves the thermal efficiency, prevents fouling, is convenient to maintenance and use, is fit to the heating of general factory and residential building and uses.
