The energy of the utility model can be absorbed rapidly by circulating water, making the circulating water heating rapidly; after discharging from the flue, the insufficient burning smoke will be absorbed by circulating tube and circulating water in the median septum, and avoid effectively heat loss, and further improve thermal efficiency; furthermore, after primary circulation of smoke in the smoke circulating tube, the stay time of smoke in smoke circulating tube will be improved, and the waste heat in smoke will be made fully use with high thermal efficiency; thus, fuel can be saved and discharge amount of dust and fume is low. The utility model has the advantages of simple structure, low cost, high adaptability, rapid heating, conservation of fuel and high thermal efficiency.
Description
Technical field
The utility model relates to a kind of boiler, relates to a kind of small-sized civil energy-efficient boiler specifically.
Background technology
Along with cities and towns, rural area, pastoral area warming adopt increasing gradually of civil boiler, the kind of civil boiler is also a lot of in the market, using many is interior dress circulating water pipe or the miniature boiler that adopts furnace water jacket, because this class boiler furnace is long-pending little, cost is low, uses so relatively be suitable for family's heating.But it is low that this type of furnace mostly exists the thermal efficiency, and it is slow to conduct heat, consumption coal height, shortcomings such as contaminated environment.And the present water-jacket typ boiler rapid heat dissipation that generally uses, the thermal losses height.In order to improve the thermal efficiency, some boiler has structurally increased the heating surface of stove, but this class boiler structure relative complex often, cost is higher; Also some boiler improves the structure of boiler from environmental angle, but can not fully burn the exhaust gas temperature height owing to most of boilers exist fuel, thermal loss is bigger, and the thermal efficiency is low, and furnace heat runs off to be wasted, so waste fuel, flue gas is bigger, contaminated environment.
Summary of the invention
The purpose of this utility model is to provide a kind of thermal efficiency height, and heat loss is few, fuel saving, and flue dust is less, and is simple in structure, energy-saving efficient boiler with low cost.
The purpose of this utility model is to realize by following technical scheme:
A kind of energy-saving efficient boiler, comprise water-jacket typ body of heater, water inlet pipe and outlet pipe, it below the combustion chamber of this body of heater grate, body of heater above the said combustion chamber connects flue, its structural feature is: connect water-jacket typ flue gas recirculation tube at said flue place, this water-jacket typ flue gas recirculation tube jackshaft is to the median septum that dress recirculated water in one is installed, and said flue is connected a side of median septum, at the opposite side connection chimney of median septum.During use, the recirculated water of fuel in the direct heating water jacket's formula of the heat body of heater that the combustion chamber internal combustion produces, flue gas in the combustion chamber enters the flue gas recirculation tube by flue, because the effect of median septum, one side of flue gas median septum in the flue gas recirculation tube rises, and is forced to go out from chimney downwards from the opposite side of median septum to the top of flue gas recirculation tube again.
In said water-jacket typ body of heater boiler clothing is installed, is provided with a ventilating duct between this boiler clothing and the body of heater at least, this ventilating duct is provided with the oxygenating hole.
In said flue gas recirculation tube, be provided with ventilating water pipe.
Install in said flue gas recirculation tube and scrape hawk, this is scraped and connects the pull bar that leads to flue gas recirculation tube outside on the hawk.
Be provided with on said flue gas recirculation tube top and scrape hawk, be provided with the crank of scraping hawk in the connection in flue gas recirculation tube outside.
Said bottom of furnace body is installed ash bin, and ash tuft is installed in this ash bin, and the header board of this ash tuft is provided with air vent, and cover plate is installed at this air vent place.
Be provided with crater at said body of heater top.
Advantage of the present utility model is: the utility model adopts the water-jacket typ body of heater, is provided with the flue gas recirculation tube again at the flue place, and the heat in the combustion chamber can be absorbed by the recirculated water in the furnace water jacket rapidly, makes the recirculated water heating fast, and the heat in the combustion chamber is fully utilized; Not clean-burning flue gas contains certain heat in the combustion chamber, when flue is discharged, through the flue gas recirculation tube, the recirculated water and the interior recirculated water of median septum that are recycled in the tube fully absorb, prevent that effectively heat scatters and disappears, further improve the thermal efficiency, and the trend of the flue gas in the flue gas recirculation tube is from top to bottom, discharges from top to bottom, through once circulation, increased the holdup time of flue gas in circulating barrel, the waste heat in the flue gas is fully utilized, the thermal efficiency is very high, fuel saving, flue gas is because of fully burning, so the discharge capacity of flue dust is very low.The utility model is simple in structure, and is with low cost, and adaptability is strong, and heating is fast, fuel saving, thermal efficiency height.
The further advantage of the utility model is: the utility model is owing to further installed boiler clothing, on boiler clothing, be provided with ventilating duct and oxygenating hole, avoiding heat directly when body of heater scatters and disappears, can reach the oxygenating burning again, increased combustion efficiency, improve the thermal efficiency, and make fuel combustion abundant, environment protecting is good; The utility model is provided with ventilating water pipe in the flue gas recirculation tube, make the heat in the flue gas can in time be recycled the water absorption, and heat is fully utilized, and the thermal efficiency is very high; Since be provided with scrape hawk and on scrape hawk, the dust stratification on ventilating water pipe and the circulating barrel is in time removed, do not influence recirculated water heat absorption.
