Abstract
The utility model discloses a smoke tube boiler which comprises a water sleeve furnace body, wherein a rear furnace body of a hearth is internally respectively vertically provided with a smoke tube and a chimney from front to rear, and the upper end of the smoke tube is communicated with the upper part of the hearth through an upper smoke chamber; and the lower end of the smoke tube is communicated with the bottom of the chimney through a lower smoke chamber, and the top surface of the upper smoke chamber is provided with a cleaning door. The smoke tube boiler provided by the utility model has the advantages that the structure is simple, the deashing is easy, the heat utilization efficiency of the boiler is contributed to improving, and the using cost is reduced.
Description
Technical field
The utility model relates to a kind of small-sized coal-fired hot-water boiler, particularly a kind of flue tube boiler.
Background technology
Flue tube boiler has the advantage of making easily, can make full use of the boiler space, but the knot ash of smoke pipe inwall easy to clean not influences the raising of boiler thermal output.
Summary of the invention
The purpose of the utility model is to provide a kind of flue tube boiler, and it is simple in structure, is easy to deashing, helps improving the heat energy utilization rate of boiler, reduces use cost.
The technical scheme that the utility model is taked is; A kind of flue tube boiler; Comprise water jacket furnace, by smoke pipe and chimney vertically are being set respectively after going to, the upper end of smoke pipe is connected with upper furnace through last smoke-box in the body of heater at burner hearth rear; The lower end of smoke pipe is connected with chimney bottom through following smoke-box, on the last smoke-box end face cleaning door is being set.
As a kind of improvement of the utility model, said smoke pipe is at least two that vertical spacing is uniformly distributed with.
As a kind of improvement of the utility model, the cleaning door top is being provided with a stay-warm case.
When the utility model used, the high-temperature flue gas of burner hearth burning generation passed through last smoke-box and gets into smoke pipe, drops to smoke-box through smoke pipe again, again through smoke-box entering chimney discharge down.
Owing to adopted technique scheme, the smoke pipe inwall of the utility model boiler can be cleared up through last smoke-box deashing window by tool using easily, can keep the thermal efficiency of boiler not descend.The utility model is simple in structure, is easy to deashing, helps improving the heat energy utilization rate of boiler, reduces the coal use amount, reduces use cost.
Description of drawings
To combine accompanying drawing that the utility model is done further detailed explanation below.
Fig. 1 is the main TV structure sketch map of the utility model.
The specific embodiment
A kind of flue tube boiler; As shown in Figure 1; Comprise water jacket furnace 1, by smoke pipe 7 and chimney 6 vertically are being set respectively after going to, the upper end of smoke pipe 7 is connected with upper furnace through last smoke-box 4 in the body of heater 1 at burner hearth 2 rears; The lower end of smoke pipe 7 is connected with chimney 6 bottoms through following smoke-box 8, on last smoke-box 4 end faces cleaning door 5 is being set.
As a kind of improvement of the utility model, at least two of being uniformly distributed with for vertical spacing of said smoke pipe 7.
As a kind of improvement of the utility model, cleaning door 5 tops are being provided with a stay-warm case 3.
When the utility model used, the high-temperature flue gas of burner hearth burning generation passed through last smoke-box and gets into smoke pipe, drops to smoke-box through smoke pipe again, again through smoke-box entering chimney discharge down.
