Abstract

The utility model relates to a high efficiency energy-saving boiler which comprises the outer shell of the boiler. The lower part of the outer shell of the boiler is provided with a lower combustion chamber 4, a movable fire grate 1 is arranged above the combustion chamber 4, and an upper combustion chamber 3 is arranged above the fire grate 1. A plurality of rows of horizontal water tubes 5 are arranged above the upper combustion chamber 3, a vertical smoke tube 6 with threads is arranged above the water tubes 5, and the upper end of the smoke tube 6 is provided with a tower-shaped flue 8. A transversal water tube 7 for bundle current is arranged in the flue 8, and the top pf the flue 8 is provided with a chimney 9. The utility model which has the advantage of high combustion efficiency can use the residual heat of smoke fully.

Description

High-efficient energy-saving boiler

Realizing referring to a kind of industrial boiler especially with good energy-saving effect with the novel combustion apparatus field that belongs to.

At present industrial all kinds of boilers are a lot, form also is various, for improving efficiency of combustion, large-sized boiler is with main developing direction in the fluidized bed combustion at present, but miniature boiler is not also used this class technology at present, miniature boiler at present effectively energy savings and few, have a large amount of waste heats to be wasted, consider small-sized normal pressure and Micropressure boiler that the whole nation is a large amount of, the energy of waste is very considerable.

Goal of the invention in utility model is to disclose a kind of energy-saving efficient boiler that makes full use of waste heat.

The realization the technical solution of the utility model is as follows: comprise stove outer covering, its underpart is a lower combustion chamber 4, it on it moving grate 1, the top of fire grate 1 is a upper combustion chamber 3, upper combustion chamber 3 tops are that many horizontal rows are put water pipe 5, and screwed pipe 6 is put for perpendicular in water pipe 5 tops, and the upper end of smoke pipe 6 is a turriform flue 8, be provided with the horizontal water pipe 7 of line in flue 8, the top of flue 8 is a chimney 9.

General structure of the present utility model is divided into four flow processs, and its inner bag is four joints, and inside and outside courage is by the top end socket, lower raft is welded into integral body, and central dividing plate is divided into warm water chamber and following boiling water chamber, reservoir with boiler, moving grate, boiled water tank is by being connected to form a big linker communicating pipe.Moving grate 1 is divided into two combustion chambers up and down with the combustion chamber, upper combustion chamber by arc formula garden, half garden arch structure 2 directly and inner bag be welded into integral body, make and form upper combustion chamber 3 between movable burner hearth and the garden arch structure, form second lower combustion chamber 4 between the casting furnace grate of moving grate 1 and activity, garden arch structure 2 forms three and half garden shape fire tubes with the joint portion of inner bag, formed flame is finished first flow process of flue gas flow in two combustion chambers by three and half garden shape fire tubes, the flame flow that rises is finished second flow process of flame flow by horizontal aulic region, flame flow continues to rise, by the perpendicular threaded flue 6 bundle districts of putting, finish the 3rd flow process of flame, flame flow continues to go up continuous by the horizontal water pipe 7 of multilayer line in the top Cylinder of fire tube line once more, finish the 4th flow process of flame flow, the nubbin of flame flow is discharged outside the boiler by main smoke pipe 8 and chimney 9.

The utility model efficiency of combustion height makes full use of the waste heat of flue gas simultaneously, and the utilization rate of waste heat of flue gas is because of there being the line smoke pipe simultaneously, and makes full use of after being concentrated, and has good economic benefit and social benefit.

Fig. 1 is at structural representation of the present utility model.

Fig. 2 is the side-looking structural representation of Fig. 1.

Claims

1, energy-saving efficient boiler, comprise stove outer covering, it is characterized in that the stove outer covering bottom is a lower combustion chamber 4, be moving grate 1 on it, the top of fire grate 1 is a upper combustion chamber 3, and upper combustion chamber 3 tops are that many horizontal rows are put water pipe 5, water pipe 5 tops are the perpendicular threaded flue 6 of putting, the upper end of smoke pipe 6 is a turriform flue 8, is provided with the horizontal water pipe 7 of line in flue 8, and the top of flue 8 is a chimney 9.

2, by the described energy-saving efficient boiler of claim 1, it is characterized in that upper combustion chamber 3 by arc formula garden, half garden structure 2 directly and inner bag be welded into integral body.
