A kind of diagrammatic cross-section of embodiment of a kind of horizontal internal combustion boiler that Fig. 2 is proposed for foundation the utility model.

Fig. 3 is a kind of section signal of the horizontal internal combustion boiler another embodiment proposed according to the utility model Figure.

In figure：Taper flue before 1-；2- corrugated flues；Taper flue after 3-；4- return combustion chambers；5- front smoke boxs；6- Smoke box afterwards；7- shells；8- is exported；9- pyrosphere smoke pipes；10- two return smoke pipes；11- water inlet pipes.

Embodiment

Specific embodiment of the present utility model and the course of work are further described below in conjunction with the accompanying drawings.

The orientation such as upper, lower, left, right, front and rear in present specification term be based on position relationship shown in the drawings and Establish.Attached drawing is different, then corresponding position relationship is also possible to change therewith, therefore cannot be interpreted as with this to protecting model The restriction enclosed.

As shown in Figure 1, a kind of horizontal internal combustion boiler, the boiler includes flue, return combustion chamber 4, be arranged on before flue before Smoke box 5, rear smoke box 6, shell 7 and the outlet 8 for being located at the top of shell 7 being arranged on after return combustion chamber 4.Flue, return combustion chamber 4, preceding cigarette Case 5 and rear smoke box 6 are arranged in shell 7, and shell 7 is usually cylinder.Smoke pipe is additionally provided with the shell 7 on flue top, The smoke pipe includes two return smoke pipe 10 and pyrosphere smoke pipe 9.Flue is combustion chamber, and flue is included before setting gradually from front to back Taper flue 1, corrugated flue 2 and rear taper flue 3；Taper flue 3 is connected between corrugated flue 2 and return combustion chamber 4 afterwards.Strile-back Room 4 is ellipse, sets one or two.Return combustion chamber 4 is the component for bearing external pressure as flue.

As shown in Fig. 2, when return combustion chamber 4 sets one, 4 height of return combustion chamber is less than its width.

As shown in figure 3, when return combustion chamber 4 sets two, return combustion chamber 4 and flue are respectively provided with two correspondingly, two stoves Courage and two return combustion chambers 4 are with the vertical axial direction of the shell 7（It is front and rear to）Median plane is symmetrically arranged same for symmetry axis Horizontal plane.Fig. 3 is stepped profile figure, shows the deployment scenarios and return combustion chamber 4 of the two return smoke pipe 10 in the front of return combustion chamber 4 The setting of back tube sheet.

Pyrosphere smoke pipe 9 is the 3rd backhaul smoke pipe, is arranged in the outside of return combustion chamber 4.Burn and strile-back and all occur in highest pyrosphere Below smoke pipe.

The horizontal internal combustion boiler can be steam boiler, or hot-water boiler.When the boiler is hot-water boiler When, water inlet is arranged on the top of shell 7, and the outlet 8 at the top of shell 7 is hot water outlet.When the boiler is steam boiler, pot Water inlet pipe 11 is additionally provided with shell 7, water inlet pipe 11 is arranged on the top of return combustion chamber 4, lateral arrangement.The top of water inlet pipe 11 is empty for steam Between.The usual vapor space is arranged on the top of pyrosphere smoke pipe 9.
