Detailed description of the invention
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment Attached drawing is briefly described.Obviously, described attached drawing is a part of the embodiments of the present invention, rather than is all implemented Example, those skilled in the art without creative efforts, can also be obtained according to these attached drawings other designs Scheme and attached drawing.
Fig. 1 is the structural schematic diagram of the embodiment of the present invention.
Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to design of the invention, specific structure and generation clear Chu is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair Bright a part of the embodiment, rather than whole embodiments, based on the embodiment of the present invention, those skilled in the art are not being paid Other embodiments obtained, belong to the scope of protection of the invention under the premise of creative work.In addition, be previously mentioned in text All connection/connection relationships not singly refer to that component directly connects, and referring to can be added deduct according to specific implementation situation by adding Few couple auxiliary, to form more preferably coupling structure.Each technical characteristic in the present invention, in the premise of not conflicting conflict Under can be with combination of interactions.
Referring to Fig.1, this is the embodiment of the present invention, specifically:
A kind of efficient boiler of more burning points, including the boiler body 1 with high temperature chamber, high temperature chamber is in left and right settings, high temperature chamber Left side cavity wall be equipped with several fuel outlets, the upside of high temperature chamber is equipped with air inlet 11 and gas outlet 12, and high temperature is intracavitary to be set There is the cyclic annular water pipe layer that several are from left to right equipped at intervals with, the region where the inner hole of all water pipe layers forms combustion chamber, The water pipe layer includes several water pipe rings 2 of homocentric setting from inside to outside, and all water pipe rings 2 are interconnected to be formed logical Water assembly, the upside of boiler body 1 are additionally provided with the escape pipe 4 being connected to gas outlet 12, and the upside of boiler body 1 is equipped with and air inlet 11 The air entraining pipe 3 of connection;The top of escape pipe 4 is equipped with back cover, and the back cover includes being located at right above the outlet of escape pipe 4 Flow-stopping plate 61, the outer ledge of flow-stopping plate 61 extend to form reflux set 62 down, and the outlet of escape pipe 4 is located in reflux set 62, So that being equipped with backflow gap between the outer wall and reflux set 62 of escape pipe 4, flow-stopping plate 61 is equipped with through-flow mouth 63, and through-flow mouth 63 is set In the top of the outlet of escape pipe 4, the left side wall of combustion chamber is equipped with outflow port 64, and the outflow port 64 connects with through-flow mouth 63 Logical, several described fuel outlets are laid in the surrounding of outflow port 64 in a ring.In this way, partial exhaust gas can enter from outflow port Through-flow mouth returns in combustion chamber, allows exhaust gas to participate in burning, oxynitrides and carbon monoxide are contained in exhaust gas, these nitrogen oxidations are closed Object carries out deoxidation reaction as oxidant and fuel in combustion chamber again, ultimately generates nitrogen, carbon monoxide will be used as fuel Burning is participated in, to realize the discharge for reducing pernicious gas.And exhaust gas plays the role of dropping oxygen, can reduce the burning of fuel The central temperature of severe degree, such fuel can reduce, this is also beneficial to the production for inhibiting oxynitrides, finally realize good Good environment protecting.Moreover, the setting of back cover, can allow exhaust gas to be not easy to flow out in the case where not reducing flow area Combustion chamber improves the air pressure in combustion chamber in a disguised form in this way, and then oxygen can adequately be contacted with fuel, and burning is allowed more to fill Point.Water is injected in the water inlet of water flowing component, the outlet of water flowing component can export hot water or steam.
The fuel supply pipe 7 connecting with fuel outlet is wrapped on the outer wall of escape pipe 4, the fuel supply pipe 7 is located at In backflow gap.The waste heat that exhaust gas can be efficiently used in this way, allows the waste-heat fuel of exhaust gas, allows fuel temperature with higher Degree, enables the molecule activity of fuel stronger, is convenient for full combustion.
Air inlet 11 is located at the right side of gas outlet 12.This design and the conventional design of this field are just opposite.Because one As think, oxygen inlet, since the fuel of fuel outlet can not adequately gasify, should cause as close as possible to air inlet It is difficult to realize adequately burn, and the present embodiment is acted in a diametrically opposite way, and spouting fuel is first allowed to obtain sufficiently gasifying It burns, to improve the efficiency of burning, and the exhaust gas of reflux can be allowed to participate in burning, further function as the effect of environmental protection.
Better embodiment of the invention is illustrated above, but the present invention is not limited to the embodiment, Those skilled in the art can also make various equivalent modifications or replacement on the premise of without prejudice to spirit of the invention, this Equivalent variation or replacement are all included in the scope defined by the claims of the present application a bit.
