Abstract

The utility model relates to a highly-efficient and energy-saving combine structure of a heating boiler which is round at the upper side and is square at the lower side. The combine structure adopts the advantages (heating and heat exchange)of a round boiler to manufacture a boiler flue, thereby saving the manufacture material, and having concentrated heating and heat exchange and long service life; the combine structure adopts the advantages of a square boiler to manufacture a hearth, enlarges and adjusts the hearth to have reasonable enough burning space under the condition that the boiler flue is not enlarged; and through the combine of the advantages of the round upside and the square underside, the purpose for eliminating smoke and dust, reducing burning loss and enhancing the thermal efficiency is achieved.

Description

A kind of energy-efficient combining structure of circular upper part and square lower part heating boiler

One, affiliated technical field

The utility model relates to a kind of heating boiler.Current general boiler is square, rectangle, positive square, round.

Two, background technology

General in the market heating boiler is square, round two big classes.Square and round, aspect the manufacturing consumptive material, by identical consumption coal, the identical thermal efficiency, the consumptive material of square is more, and the consumption coal is more.Because square has four right angles, position, right angle effective radius is far away, and by contrast, not as round stove contact flame impingement, heat radiation is concentrated.Round stove has lacked four right angles, and diameter has only one, and centre-to-centre spacing boiler ectosome periphery is equal to.So round boiler is in onesize heating surface area, onesize burner hearth, the fuel of same quantity, the thermal efficiency all is higher than box furnace.

Also there is defective in but round stove, and when promptly needing to enlarge boiler furnace, flue (heat exchange) part also is forced to enlarge thereupon, and promptly whole boiler enlarges thereupon, causes unnecessary waste of material.

Three, summary of the invention

In order to realize that the unnecessary expansion flue of boiler (heat exchange of being heated) part only enlarges burner hearth and can improve the thermal efficiency; Many in order to overcome square boiler furnace flue (heat exchange of being heated) position manufacturing consumptive material, and the defective of the round difference of thermal efficiency ratio, the utility model relates to a kind of energy-efficient combining structure of circular upper part and square lower part heating hot water boiler, be that the boiler combustion partial hearth is designed to square, flue (heat exchange of being heated) partial design is round, having realized that square boiler and round boiler are required when burner hearth part and flue (heat exchange of being heated) part do not need to increase synchronously or dwindle manufactures and designs requirement, promptly only enlarge and dwindle burner hearth, do not enlarge when dwindling flue (heat exchanging part of being heated), realize that higher heat is imitated to order.

The utility model solves the technical scheme that its technical problem can take: boiler furnace lower part (burner hearth part) is designed to square: 1, square body four sides greater than 10 centimetres-100 centimetres 2 of upper cylinder, can reach reasonable burning according to adjusting the burner hearth combustion space; 3, can design multiple hearth, many fire doors, the split of realization multiple hearth is rotated high temperature and is burnt, and reduces combustible loss, for condition has been created in multiple hearth energy-conserving and environment-protective design; 4, overcome round boiler furnace and flue (heat exchange of being heated) position and enlarged the consubstantiality limitation of dwindling simultaneously simultaneously, realized only transforming the effect that burner hearth can realize that just the whole house of correction of round boiler produces, and saved manufactured materials; 5, want to guarantee sufficient combustion, must guarantee the burner hearth space, if furnace cavity is little, mobile fast flue gas will have little time the combustible of after-flame and take burner hearth out of, just can't guarantee the time of staying of combustible in burner hearth, and the square burner hearth has solved the problem that furnace cavity enlarges and adjusts.

Four, description of drawings

Below in conjunction with drawings and Examples this utility model is further specified: Fig. 1 front elevation; Fig. 2 side elevational view; The square burner hearth of the preceding fire door of Fig. 3 cut away view (1) flue (2) burner hearth (3) (4) chimney (5) fire grate (6) back fire door (7) is greater than circular furnace courage part.

Five, specific embodiments;

This boiler lower part burner hearth partly manufacture square (2) flue manufacture (3) 4 at (1) 4 preceding fire door of cylinder after fire door (6) also can be designed to a plurality of fire doors, look the boiler size and adjust.The square burner hearth is greater than the outer skin portion (7) of column type flue.

Claims (2)

1, a kind of energy-efficient combining structure of circular upper part and square lower part heating boiler is characterized in that: this upper boiler divides flue partly to be column type, and the lower part burner hearth is a square.

2, according to claim 1, it is characterized in that four limits, plane of this boiler lower part square burner hearth, every limit is all greater than 10 centimetres-100 centimetres of round flue maximum gauge crusts.
