Abstract

The utility model relates to an air intake system and a chimney spot removal device of the civil vertical normal pressure heating boiler. At present, the common civil vertical normal pressure heating boiler has the defects that the combustion is incomplete; the heat efficiency is low; the smoke scale deposit can not be removed, etc. The lower part of the inner container of the boiler is provided with a blocking layer. The vicinity of the upper part of the blocking layer is provided with a secondary air inlet. The fuel is combusted through secondary air inlet functions. The fuel is fully combusted, the water of the boiler is heated in a longer stroke and the utility model realizes energy saving, high efficiency and environmental protection. As the ash removal opening is provided, the smoke scale deposit of the water boiler is removed periodically, and the stability of the performance of the boiler is ensured.

Description

A kind of civilian vertical normal-pressure boiler

The utility model relates to the air inlet system and the cigarette ash incrustation cleaning plant of civilian vertical normal-pressure boiler.

At present, the civilian vertical normal-pressure boiler that China generally uses in town and country, its essential characteristic is: form annular water storage space between boiler casing and inner bag, its relative direction is to link to each other to overflow pipe; The boiler bottom is the combustion chamber, the water after the fuel combustion in heating boiler annular water tank and the convection current water tank.The general stove of this common vertical normal pressure heating cooker exists that fuel combustion is incomplete, heat exchanger effectiveness is low, cigarette ash incrustation can't be got rid of weak points such as influencing the boiler heat absorption, and some improved boilers of the same type do not address the above problem fully.

At above-mentioned shortcoming, the purpose of this utility model provides a kind of sufficient combustion, thermal efficiency height and can clear up the civilian vertical normal pressure heating boiler of cigarette ash incrustation easily.

The purpose of this utility model is realized by following scheme: on the basis of common vertical normal pressure heating boiler, a barrier layer is set in the inside of boiler bottom, this barrier layer center has concentrates into burner, its cross-sectional area and chimney quite, offering the secondary air mouth on the boiler nearby above the separate layer; Upper boiler prolong vertically perpendicular to a side of overflow pipe or relatively both sides have cigarette ash mouth clearly.

The civilian vertical normal-pressure boiler that adopts such scheme to make, its fuel is at barrier layer bottom imperfect combustion, be mingled with more combustible, enter barrier layer top by concentrating into burner, under the air effect of secondary air mouth, the material of end burning further burns, thereby the heating annular water tank reaches the water in the overflow pipe.Because fuel is through the effect of twice air intake, thus on long stroke the water in the heating boiler, increased heat exchange area, realized higher heat exchanger effectiveness; Simultaneously, the setting of the clear cigarette ash mouth that can seal off has guaranteed that the periodic cleaning flue reaches the black dirt on the overflow pipe, thereby has realized the long-term stability of the thermal efficiency.The utility model is simple in structure, the soot emissions amount seldom, the more common vertical normal-pressure boiler of the thermal efficiency increases significantly.

Below, embodiment further specifies the utility model in conjunction with the accompanying drawings:

Fig. 1 is a front view of the present utility model;

Fig. 2 is a full sectional view of the present utility model;

As shown in Figure 1, 2, inner bag of the present utility model (1) and outer wall (2) constitute water storage space, are known to the structure of overflow pipe (3), and stone or metal plate for standing a stove on as a precaution against fire (4) is at boiler bottom, nearby, chimney (6) also can be used as the part of inside of boiler to charge door (5) above stone or metal plate for standing a stove on as a precaution against fire; Barrier layer (7) is made of under concentrating into the binding of burner (8) two parts up and down of inside of boiler as shown in Figure 2, and secondary air mouth (9) can be arranged to adjustable, and its position is above the barrier layer about 150mm; With the barrier layer is the furnace internal-lining bottom on boundary, and its height is about 1: 1.2 with the ratio of internal diameter, adds (10) three of the stay pipes of diameter 25-50mm more than the boiler internal diameter 800mm, is distributed on the barrier layer, its objective is support, fixing inside of boiler top; Clear cigarette ash mouth (11) is according to scheme manufacturing down: twice lacing wire (12) is set on inside of boiler when offering clearly the cigarette ash mouth, support member as fixing seal plate (13), between inside of boiler and outer wall with the steel plate welded closure of same thickness, when clear cigarette ash mouth length surpasses 1500mm, can offer more than two, and make it to stagger in opposite directions to arrange.

Claims (6)
