Description
Technical field
The utility model relates to a kind of new and effective biomass burner.
Background technology
For reducing fume emission, protection of the environment, many places utilize biomass burner that small-sized (less than 10 tons) coal-fired boiler reform is become biomass combustion boiler.
Traditional biomass burner, structure as shown in Figure 1.Combustion chamber and flame jet pipe are straight cylinder shape, and in the pyrogenation and combustion of living beings, it is poor that Secondary Air mixes with combustible gas, burns insufficient, and excess air coefficient is large, and flame temperature (about 1000 DEG C) is lower, smoke evacuation nitrogen oxide 500mg/Nm
3above, exceed standard 60%, boiler efficiency is lower than 70%.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of new and effective biomass burner.
To achieve these goals, the utility model adopts following technical scheme.
New and effective biomass burner, comprises combustion chamber and jet pipe, and combustion chamber is or/and jet pipe is provided with contraction section, and Secondary Air is along combustion chamber or/and the contraction section of jet pipe tangentially sprays into.
The utility model according to Combustion, hydrodynamics and heat transfer theory, the new and effective biomass burner of research and development.
Combustion chamber and flame jet pipe are cylinder scaling type.First air feeds bottom fire grate.Biomass fuel is on fire grate after combustion and pyrolysis, and a large amount of burning limits, combustible gas limit is accelerated.In combustion chamber and spout throat (contraction section), Secondary Air tangentially sprays into flame along round tube wall, flame flow High Rotation Speed, and form whirlpool, strongly entrainment the Secondary Air of infeed, combustible gas and Secondary Air fully mix, and burning completely.Practice finds, combustion chamber throat is than nozzle throat, and Secondary Air is twice, better effects if.Meanwhile, constrictor is warm to the burning reflected radiation on fire grate, improves fire grate upper space temperature, accelerates pyrolytic gasification and the combustion process of fuel, makes it more violent, abundant, complete.Secondary Air tangentially feeds at the secondary of combustion chamber and spout throat respectively, guarantees complete combustion of fuel, improves efficiency of combustion more than 5%.The flame flow of about 1500 DEG C sprays in boiler at a high speed, enhances the radiation in stove and heat convection, improves boiler efficiency.
This new and effective biomass burner, in smoke evacuation, sulfur content extremely low (almost can't detect), containing grey 5mg/Nm
3within, amount of nitrogen oxides 150mg/Nm
3left and right, lower than fire coal by more than 40%, discharge completely up to standard.Flame temperature about 1500 DEG C, efficiency of combustion more than 98% is the special equipment that small-sized (less than 10 tons) coal-fired boiler reform becomes biomass fuel boiler.After coal-fired boiler reform, because furnace flame temperature improves, boiler thermal output improves about 5%.In flue gas, ash content and sulfide are extremely low, and boiler abrasion greatly reduces with corrosion, and service life improves more than 30%.
The beneficial effects of the utility model are, new and effective biomass burner, and the scaling type of combustion chamber and jet pipe designs, fuel mixes with Secondary Air fully, completely, flame temperature is high, and boiler efficiency is high in burning, without wearing and tearing, corrosion-free, fume emission is completely up to standard, energy-saving and emission-reduction, there is good economic benefit and social benefit, be subject to the popular welcome of user.
Certainly, implement arbitrary product of the present utility model might not need to reach above-described all advantages simultaneously.

Detailed description of the invention
Be clearly and completely described the technical solution of the utility model below in conjunction with accompanying drawing, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
In description of the present utility model, it should be noted that, orientation or the position relationship of the instruction such as term " " center ", " on ", D score, "left", "right", " vertically ", " level ", " interior ", " outward " they be based on orientation shown in the drawings or position relationship; be only the utility model and simplified characterization for convenience of description; instead of instruction or imply the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.In addition, term " first ", " second ", " the 3rd " only for describing object, and can not be interpreted as instruction or hint relative importance.
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, concrete condition the concrete meaning of above-mentioned term in the utility model can be understood.
As shown in figs 2-4, new and effective biomass burner, comprises combustion chamber 1 and jet pipe 2, and combustion chamber 1 and jet pipe 2 are provided with contraction section 3, and Secondary Air 4 tangentially sprays into along the contraction section 3 of combustion chamber 1 and jet pipe 2.
Combustion chamber 1 and flame jet pipe 2 are cylinder scaling type.First air 9 feeds bottom fire grate.Biomass fuel is on fire grate after combustion and pyrolysis, and a large amount of burning limits, combustible gas limit is accelerated.At the contraction section 3 of combustion chamber 1 and spout 2, Secondary Air 4 tangentially sprays into flame 5 along round tube wall, flame flow High Rotation Speed, and form whirlpool, strongly entrainment the Secondary Air 4 of infeed, combustible gas and Secondary Air fully mix, and burning completely.Combustion chamber throat is than nozzle throat, and Secondary Air 4 is twice, better effects if.Meanwhile, the burning reflected radiation heat 6 on contraction section 3 pairs of fire grates of combustion chamber 1, improves fire grate upper space temperature, accelerates pyrolytic gasification and the combustion process of fuel, makes it more violent, abundant, complete.Secondary Air 4 tangentially feeds at the secondary of combustion chamber and spout throat respectively, guarantees complete combustion of fuel, improves efficiency of combustion more than 5%.The flame flow of about 1500 DEG C sprays in boiler at a high speed, enhances the radiation in stove and heat convection, improves boiler efficiency.
Burner is also provided with corresponding charging 7, cooling water 8 device, it will not go into details.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
