Abstract

The utility model relates to a small energy-saving boiler for heating. Compared with the existing various boilers, the difference of the utility model is that the utility model is provided with a large and high flue water jacket (8). The height of the flue water jacket (8) is more than three times compared with the height and the width of a boiler body (1), and the flue water jacket (8) has enough width. A plurality of water tubes (4) communicated with the water jacket of the boiler body are arranged in a hearth in a transversal way. The upper end of the flue water jacket (8) is provided with a water outlet (9). Because the boiler body is small, the coal consumption is low, a flue and the flue water jacket are high and large to enable fuel to combust fully, and the water outlet is high to accelerate the speed of heat circulation. The utility model which does not need a water pump has the advantage of simple structure. The utility model is suitable for small factories and residents whose household house areas are large.

Description

The miniature energy-saving heating boiler

The utility model relates to a kind of miniature energy-saving heating boiler.

Improvement to boiler in existing technology is varied.General purpose is energy-efficient.A lot of structures are set about from body of heater, but total trend is big body of heater, bottom flue.Mode is provided with the multilayer water jacket, anti-burning, secondary air, and adding water-gas is combustion-supporting etc.Structure becomes increasingly complex.Effect is unsatisfactory, all haves much room for improvement.

The purpose of this utility model is to break the intrinsic form of present miniature boiler, designs a kind of new energy-efficient heating boiler.

Scheme of the present utility model is as follows: it is big to change existing heating stove body of heater, and the intrinsic shape that flue is little is increased increasing with flue and flue water jacket, and the height that makes the flue water jacket is more than three times of body of heater height and width.The height of flue water jacket is more than two times of length of body of heater.And water jacket is set on body of heater, burner hearth is provided with the traverse cycle water pipe.The extremely special heating stove of this shape from the surface, because flue and water jacket are increased increasing, body of heater makes the coal that enters in the body of heater few and can fully burn for a short time, furnace water jacket, laterally the setting of water pipe makes full use of energy, adds hot water effectively.Be positioned at the delivery port potential energy height of flue water jacket top simultaneously, the flow velocity of recirculated water is accelerated,, reach desirable effect even heating plant is heated rapidly without pump.

Below in conjunction with drawings and Examples the utility model is illustrated.

Fig. 1-Fig. 3 is an embodiment of the present utility model.Wherein Fig. 1 is the utility model sectional view, and Fig. 2 is a front view, and Fig. 3 is that A-A of Fig. 2 is to view.

With the present embodiment is example: the length of body of heater (1) is about 1100cm, 1/2 (flue water jacket height can be 2500cm) of not enough flue water jacket (8).The about 600cm of height of body of heater (1), the height of flue water jacket (8) are more than 3 times of body of heater height.The width (being about 600cm) of body of heater (1), 1/4 of the height of not enough flue water jacket (8).The diameter phi 350cm of flue water jacket (8) is slightly larger than 1/2 of body of heater width.Flue water jacket (8) Gao Erkuan.The developed width of flue is φ 200cm.This is the most tangible characteristics of the present utility model.

It is that air door, (5) are for advancing fire door that body of heater (1) is gone up (2).Form furnace water jacket between outer courage (6) and the inner bag (7).Horizontal water pipe (4) and furnace water jacket that the latter half of transverse row of burner hearth (11) is shown more than one communicate.These traverse cycle water pipes (4) have utilized the interior fuel of burner hearth (11) fully, make Energy Efficient improve using value.Delivery port (9) is above the flue water jacket, because flue water jacket (8) is very high, the height of adding body of heater (1) makes the actual height of delivery port (9) about about 3 meters.Hot water joins from such height and cooling system, has accelerated the speed of recirculated water, and without water pump, small-sized like this boiler can make 300M rapidly ²The indoor temperature that is heated to application.The below of fire grate (13) is ash bucket (3).

Claims

1, a kind of miniature energy-saving heating stove, comprise body of heater (1), burner hearth (11), air door (2), coal feed point (5), the furnace water jacket that stove outer covering (6) and inner bag (7) form, flue (10), flue water jacket (8), be positioned at the delivery port (9) of flue water jacket (8) upper end, it is characterized in that the utility model has the flue water jacket (8) of enough Gao Erda, the height of flue water jacket (8) (counting from the furnace roof end) is the height of body of heater (1) and more than 3 times of width, more than 2 times of the length of body of heater (1), the width of flue water jacket (8) is more than or equal to 1/2 of body of heater width.

2, a kind of miniature energy-saving heating boiler according to claim 1 is characterized in that being provided with in the above-mentioned burner hearth (11) the horizontal water pipe (4) more than, two ends and communicated by the furnace water jacket that forms between stove outer covering (6) inner bag (7).
