Abstract

The utility model relates to a lamellar flue-pipe boiler, which is composed of a combustion chamber, flues, a boiler shell, etc., wherein, the arrangement of the flues are lamellar; the combustion chamber and the flues are all arranged in the medium of the boiler; medium interlayers are arranged between the flues and the combustion chamber; so that the phenomenon of dry combustion can be avoided; the heat-transfer area of the boiler can be enlarged; the exhaust gas temperature of the boiler is reduced; the heat efficiency of the boiler can be increased.

Description

Stratiform flue boiler

The utility model belongs to a kind of combustion apparatus, the combustion apparatus of the fuel of particularly can choosing any one kind of them.

Existing boiler is constructed combustion chamber and exhaust gases passes with common metal plate or nonmetal masonry, and the common metal plate and the masonry that are positioned at the high-temperature region damage easily because of long-term dry combustion method.

The purpose of this utility model is to provide a kind of heating surface area that both can enlarge boiler, is not easy the stratiform flue boiler that damages because of dry combustion method again.

The purpose of this utility model realizes by following proposal: combustion chamber and the flue of forming boiler with tabular component; Flue becomes layered arrangement, and combustion chamber and flue all place among the working medium of boiler, between flue and the flue or the working medium interlayer of heat absorption arranged between flue and combustion chamber.

Below in conjunction with drawings and Examples the utility model is described in further detail:

Accompanying drawing 1 is the stratiform flue boiler that is arranged above and below;

Accompanying drawing 2 is tandem stratiform flue boilers.

In the accompanying drawings, [1] is shell, and [2] are fuel inlets, and [3] are bases.Fuel enters burning the combustion chamber [5] from fuel inlet [2], and the high-temperature flue gas that the burning back produces enters in first flue [7] by trunnion [6], enters second flue [9] by trunnion [6] again, discharges from exhanst gas outlet [11] at last.[4] be the working medium inlet, working medium enters boiler heat absorption back from working medium inlet [4] and discharges from outlet [10].Combustion chamber [5], trunnion [6], first flue [7], second flue [9] all place among the working medium of boiler.[between 71, between first flue [7] and combustion chamber [5] working medium layer [8] is arranged all at second flue [9] and first flue.Obviously,, both enlarged the heat transfer area of boiler, avoided the generation of dry combustion method phenomenon again owing to the existence of working medium interlayer [8].First flue [7] and second flue [9] have in the accompanying drawings only drawn.In practical matter, the 3rd flue can also be arranged, the 4th flue or the like.And the working medium interlayer can a combuster [5] and first flue [7] between one or have only first flue [7] and second flue [9] between one; Also can have a plurality ofly, promptly between first flue [7] and combustion chamber [9], and working medium interlayer [81 be arranged all between each flue.Said tabular component can be parallel to each other, also can be not parallel; Can be the plane, also can be curved surface.

Embodiment one: flue is arranged in stratiform up and down, just becomes the stratiform flue boiler that is arranged above and below as shown in Figure 1.

Embodiment two: stratiform before and after flue is arranged in just becomes tandem stratiform flue boiler as shown in Figure 2.

Embodiment three: the stratiform flue and the tandem stratiform flue that are arranged above and below are combined, just become and mix the stratiform flue boiler of arranging.

The utility model is simple in structure, and is reasonable in design, enlarged the heat transfer area of boiler, reduced the exhaust gas temperature of boiler, can improve the thermal efficiency of boiler, both having can be used for water is the boiler and the home furnace of medium, and can be used for again with other fluids is the heat transmission equipment of medium.

Claims

1. a stratiform flue boiler is made up of combustion chamber, flue, shell etc., and it is characterized in that: flue becomes layered arrangement, and the working medium interlayer is being arranged between flue and the flue or between flue and combustion chamber.

2. a kind of stratiform flue boiler as claimed in claim 1 is characterized in that flue is aligned to stratiform up and down.

3. a kind of stratiform flue boiler as claimed in claim 1 is characterized in that flue is aligned to the front and back stratiform.

4. a kind of stratiform flue boiler as claimed in claim 1 is characterized in that: its flue is the stratiform of the mixing arrangement of 7 one-tenths of the stratiform flue that will be arranged above and below and the combinations of tandem stratiform flue.

5. a kind of stratiform flue boiler as claimed in claim 1 is characterized in that the working medium interlayer is all being arranged between flue and the combustion chamber and between each flue.
