Description
Technical field
The present invention relates to steam boiler, particularly relate to a kind of efficient energy-saving steam boiler.
Background technology
Boiler is a kind of energy conversion, and it is mainly by energy transform into heat energies such as the chemical energy in fuel, electric energy, and through steam or the organic heat carrier of boiler output high temperature, high pressure, the boiler that wherein produces steam is called as steam boiler.How to improve boiler structure with reach fuel combustion more fully, increase the heat exchange amount, promote boiler thermal output, reduce the purposes such as customer using cost, be that the boiler design technical staff is devoted to the problem solved always.
Summary of the invention
The purpose of this invention is to provide a kind of efficient energy-saving steam boiler, to solve the problem that boiler thermal output of the prior art is low and the heat conversion is insufficient, heat utilization efficiency is lower.
The technical scheme of a kind of efficient energy-saving steam boiler of the present invention is as follows: include furnace body, be positioned at the pot body of furnace body top and be located at the chimney of pot bodies top; Be provided with combustion chamber in described furnace body; Its special feature is:
(1) be provided with drum in the pot body, in drum, lateral arrangement has top smoke pipe, middle part smoke pipe and bottom smoke pipe from top to bottom; Be provided with the second smoke box in the pot body outside, be provided with the first smoke box in the pot body outside on the second smoke box opposite and be positioned at the 3rd smoke box above the first smoke box; Described combustion chamber is communicated with the first smoke box; described the first smoke box is communicated with the second smoke box by the bottom smoke pipe; described the second smoke box is communicated with the 3rd smoke box by the middle part smoke pipe, and described the 3rd smoke box is communicated to outlet flue by the top smoke pipe, and described outlet flue is communicated to chimney; This programme, owing to having adopted many backhauls structure of turning back, has increased the heating surface area, obviously can greatly improve the thermal conversion efficiency of boiler;
(2) also include drum in the pot body, the impurity produced for ease of combustion process is easy to discharge boiler, and the bottom of described drum is provided with the down-comer be connected on drum;
(3) the combustion chamber cross section in furnace body is for elliptical configuration; Although be generally with the burner hearth of boiler in prior art that burner hearth square, this structure is practical and convenient but heat insulation effect is poor and square burner hearth easily produces the burning dead angle and cause the insufficient and then structure that make edge easily produce slagging scorification, more difficult cleaning of fuel combustion herein to be compared, adopt the combustion chamber of this structure can make combustion chamber without corner, be difficult for producing slagging scorification, pile up impurity, temperature can distribute more uniformly, reduces dangerous;
(4) also dispose outside furnace body and spray into the formula feeding screw, this discharging opening that sprays into the formula feeding screw is tilted to the fuel inlet of combustion chamber and is communicated with; Adopt this scheme, fuel is sent in combustion chamber to be tilted to upper type through spraying into the formula feeding screw, is convenient to fuel biomass fuels such as (especially) straws and, to float short side formula suspension combustion, increases the burning area of fuel, improve the utilization rate of fuel, reduce fuel consumption.
As a kind of embodiment of such scheme, described top smoke pipe, middle part smoke pipe, bottom smoke pipe can be designed to each and be comprised of the some monomer smoke pipes that are parallel to each other.This structure has adopted many backhauls structure of turning back, and has strengthened as far as possible the heating surface area, obviously more contributes to improve the thermal conversion efficiency of boiler.
For combustion gas better, as the improvement of such scheme, can between outlet flue and chimney, by installing air-introduced machine additional, be connected.
In order to make fuel more even in the indoor layout of boiler combustion, as the optimization to such scheme, fuel inlet that also can described combustion chamber is set to 2.
To sum up, the beneficial effect of a kind of efficient energy-saving steam boiler of the present invention is: in boiler body, smoke pipe adopts many backhauls structure of turning back, and has increased heating surface, has improved thermal efficiency conversion; Chamber structure ovalize structure, can make fuel be not easy to produce slagging scorification in surrounding in combustion process; The bottom of drum is communicated with some down-comers, is conducive to grey matter, waste material are discharged; Spray into formula feeding screw discharging opening for the upward spray of tilting, make fuel that burning area more fully be arranged, can improve efficiency of combustion.

The specific embodiment
Disclosed all features in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary), unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is,, unless special narration, each feature is an example in a series of equivalences or similar characteristics.
Fig. 1 to Fig. 5 is several embodiment that application has a kind of efficient energy-saving steam boiler of the present invention technical scheme.A kind of efficient energy-saving steam boiler of the present invention comprises furnace body, be positioned at the pot body of furnace body top and be located at the chimney of bodies top; Be provided with combustion chamber in described furnace body; Fig. 1 has clearly shown the main innovation part of the present invention on the pot body: be provided with drum 8 in the pot body, in drum 8, lateral arrangement has top smoke pipe 7, middle part smoke pipe 6 and bottom smoke pipe 5 from top to bottom; Be provided with the second smoke box 3 in the pot body outside, be provided with the first smoke box 2 in the pot body outside on the second smoke box 3 opposites and be positioned at the 3rd smoke box 4 above the first smoke box 2; Described combustion chamber 1 is communicated with the first smoke box 2, described the first smoke box 2 is communicated with the second smoke box 3 by bottom smoke pipe 5, described the second smoke box 3 is communicated with the 3rd smoke box 4 by middle part smoke pipe 6, and described the 3rd smoke box 4 is communicated to outlet flue 11 by top smoke pipe 7, and described outlet flue 11 is communicated to chimney.
