Abstract

The invention relates to the technical field of energy utilization and combustion, and particularly discloses an air magnetization combustion-supporting system which comprises an air inlet pretreatment module, a flow velocity and flow pattern regulation and control module, a magnetization treatment module, a mixed diffusion enhancement module, a combustion module and an online monitoring and closed-loop control module.

Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of energy utilization and combustion, and particularly relates to an air magnetization combustion-supporting system. BACKGROUND

[0002] In the technical field of energy utilization and combustion, improving combustion efficiency and reducing pollutant emissions has always been the core research goal. With the rapid development of industry, various types of combustion equipment are widely used in energy production, transportation, industrial manufacturing and many other industries. Energy waste and environmental pollution problems caused by the combustion process are increasingly prominent, and the demand for optimization and improvement of existing combustion technology is increasingly urgent.

[0003] Currently, traditional combustion systems mainly focus on the simple mixing of fuel and air and the ignition combustion process. For the activation process of oxygen molecules, traditional combustion technology completely relies on oxygen molecules in a natural state to participate in the reaction. Oxygen molecules in a natural state are in a triplet ground state, and their spin orientation distribution is fixed. In chemical reactions, a high pairing energy barrier needs to be overcome to dissociate into active oxygen atoms or form active states with oxidation ability. This makes the initial rate of the fuel-oxygen key reaction path slow, and the cascade reaction of the chain growth step is difficult to quickly enter the high reaction rate interval, limiting the overall rate of the combustion reaction and the energy conversion efficiency.

[0004] To this end, the air magnetization combustion-supporting system is provided to solve the above problems. SUMMARY

[0016] Preferably, the flow rate / flow pattern control module includes a mass flow meter, a precision throttle valve, and a flow pattern shaper (selected from a honeycomb flow channel, a static mixer, or an energy-saving vortex generator), which is used to adjust the gas into processed air with a target residence time t_res and a Reynolds number Re, where the engineering reference range of t_res is 5-200 ms, and the engineering reference range of Re is 500-5000, and provides a B_flow signal to the closed-loop control module.

[0017] Preferably, the magnetization treatment module includes at least one set of permanent magnet arrays or electromagnetic coils and magnetic flux guides, which is used to apply an effective working field strength (reference range of 0.02-0.5 T inside the channel) and a field gradient (reference range of 1-50 T / m) on the processed air, and outputs an MF_signal through the arranged magnetic field sensors to spin bias and micro-dynamics disturb oxygen molecules inside the channel to obtain magnetized activated air.

[0018] Preferably, the magnetization treatment module further includes a spin polarization enhancement subunit selected from a low-power radio frequency / microwave pulse coil, a local electric field modulation plate, or a mechanical shear micro-vortex unit, which is used to perform additional spin polarization or energy state disturbance on the magnetized activated air to form enhanced magnetized activated air, and the spin polarization enhancement can be switched by the closed-loop control module between the on and off working states to evaluate the performance.

[0019] Preferably, the mixing diffusion enhancement module comprises a static or swirled mixer and an atomization optimization assembly cooperatively arranged with the fuel injector; the mixing diffusion enhancement module is used to contact and atomize the magnetized activated air with the fuel, so that the droplet size distribution of the liquid fuel is in the range of 10-100 μm, to obtain a fuel-air mixture, and output a Mix_quality indication signal by an online mixing quality detector.

[0024] Compared with the prior art, the present application has the following beneficial effects:

[0025] (1) The application applies a directional high gradient magnetic field to the oxygen molecules entering the combustion zone, and if necessary, assists with coherent electromagnetic pulses, so that the spin orientation of the O2 molecules originally in the triplet ground state is locally biased and relatively redistributed. According to the coupling relationship between the electron spin and the chemical reaction barrier, the spin bias can reduce the pairing energy barrier required in the pairing / dissociation process, thereby increasing the probability of oxygen molecules dissociating into active oxygen atoms or forming short-lived active states with higher oxidation ability. The interaction of the magnetic field gradient and the local flow field also changes the collision frequency and angular momentum distribution between oxygen molecules and surrounding molecules, making oxygen molecules more likely to collide effectively rather than elastically scatter during collision and energy transfer. As a result, the activity center density of the system in the reaction precursor stage (such as the transient concentration of atomic oxygen or excited oxygen state) is significantly improved, thereby significantly accelerating the initial rate of the fuel-oxygen key reaction path and the cascade of chain growth steps, making the initial state of the combustion reaction enter the high reaction rate interval faster.

[0026] (2) In the present application, the overall improvement of combustion uniformity, ignition delay and energy conversion efficiency (macroscopic / system level); the above-mentioned microscopic activity promotion and the interaction of magnetic field-fluid together cause the "magnetized activated air" entering the combustion zone to exhibit higher effective diffusivity and better mixing uniformity in a macroscopic manner. Specifically, in the mixing section and the combustion front, the local ratio fluctuation of oxygen and fuel molecules is suppressed, the size and duration of local oxygen-poor or oil-rich regions are shortened, and the contact area of fuel particles (or droplets) and active oxygen is increased, promoting more uniform combustion front condition distribution.

[0030] Please refer to Figure 1 The air magnetization combustion-supporting system adopts the following scheme:

[0034] Flow rate / flow pattern regulation module: mass flow meter + honeycomb flow channel shaping, target residence time tres~ 100 ms (design range 5-200 ms), Re~ 2000 -> output treated air.

[0035] Magnetization treatment module: custom permanent magnet + soft magnetic guide, effective working field strength BBB = 0.08 T (i.e. 80 mT) within the channel, field gradient ~ 10 T / m; optional radio frequency unit off (passive permanent magnet used in this embodiment) -> output magnetized activated air.

[0039] Diagnosis / maintenance module: record running data, calculate energy saving and emission improvement.

[0040] II. Baseline and assumptions ("off" = reference; "on" = system enabled):

[0041] Target heat output: 5.0 MW (steady state).

[0042] Natural gas LHV (estimated, used for calculation): 35.0 MJ / m 3 .

[0043] Reference (off) boiler thermal efficiency ηbase\eta_{base}ηbase= 85.00% (0.85).

[0044] System (on) boiler thermal efficiency ηsys= 88.00% (0.88) - reasonable engineering value expected for "more complete combustion / improved thermal efficiency".

[0045] Measurement errors are within ±0.5% (flow) and gas analyzer instrument error.

[0046] III. Calculate fuel volume consumption and saving rate:

[0047] Useful heat output (W): Qout = 5.0 MW = 5.0 x 10 6 W.

[0048] Reference fuel input power (W):

[0049] Qin,base = Qout / ηbase = 5 x 10 6 / 0.85 = 5882352.941 W.

[0050] System start-up fuel input power (W):

[0051] Qin,sys = Qout / ηsys = 5 x 10 6 / 0.88 = 5681818.182 W.

[0052] Convert fuel input power to natural gas volume flow (m 3 / s):

[0053] With LHV = 35.0 MJ / m 3 = 35000000 J / m 3 .

[0054] Reference volume flow (m 3 / s) = 5882352.94117647 ÷ 35000000 = 0.168 m 3 / s.

[0055] Convert to m 3 / h: 0.168067212605035 x 3600 = 605.042 m 3 / h (approximately 605.042 m 3 / h).

[0056] System start-up volume flow (m 3 / s) = 5681818.182 ÷ 35000000 = 0.162 m 3 / s.

[0057] Convert to m 3 / h: 0.162 x 3600 = 584.41 m 3 / h.

[0058] Fuel saving rate (%) = 605.042 - 584.416 / 605.042 x 100% = 3.41%.

[0059] Conclusion (Example One): Under the condition of ensuring a 5.0 MW heat output, due to the system improving the effective thermal efficiency from 85% to 88%, the natural gas consumption is reduced from 605.042 m 3 / h to 584.416 m3 h, saving about 3.41% of fuel.

[0060] IV. Emissions, Flame and Other Measurements (all experimental results are average steady-state values):

[0061] Flame Temperature (center point): Ref. 1200°C → System activated at 1230°C (about 30°C increase, helping more complete combustion). Measurement method: K-type thermocouple with optical verification.

[0062] CO (ppm, dry gas basis): Off = 80 ppm; On = 64 ppm (20% decrease). Instrument: NDIR (accuracy ± 2 ppm).

[0063] HC (ppm): Off = 40 ppm; On = 30 ppm (25% decrease).

[0064] Smoke / Black Carbon (mg / m 3 ): Off = 50 mg / m 3 ; On = 37.5 mg / m 3 (25% decrease). Measurement: Dilution tunnel + gravimetric method.

[0065] NOx (mg / m 3 ): Off = 150 mg / m 3 ; On = 153 mg / m 3 (about 2% increase, indicating NOx gain from temperature increase, which needs to be adjusted in combination with EGR and other measures).

[0066] Data acquisition frequency 1 Hz, alarm threshold and closed-loop strategy implementation (PID control air-gas ratio and magnetization state).

[0067] Example Two:

[0068] 500 kW electric output diesel generator set - field retrofit test:

[0069] I. System Parameters:

[0070] Intake air pretreatment module: medium filtration + drying (anti-fog), output clean and temperature and humidity controllable gas.

[0071] Flow rate / flow pattern control module: rectifier and static mixer, target residence time tresabout 50 ms, output treated air.

[0076] Diagnosis / maintenance module: record fuel consumption, emission trends and maintenance recommendations.

[0077] II. Reference and assumptions ("off" = reference; "on" = system):

[0078] Electric output: 500 kW (steady load).

[0079] Diesel LHV approximate calculation: 43 MJ / kg; diesel density 0.84 kg / L → LHV ≈ 43 x 0.84 = 36.12 MJ / L.

[0080] Reference (off) system integrated electric efficiency (mechanical + power generation) ηbase= 38.00% (0.38).

[0081] System (on) efficiency assumption of a small increase of 5% relative value: ηsys= ηbase x 1.05 = 0.399 (39.9%); equivalent to a decrease in fuel input power.

[0082] III. Calculate fuel volume (L / h) and savings rate;

[0083] Target electric output (W): 500 kW = 500,000 W.

[0084] Reference fuel input power (W): Pin,base= 500,000 / 0.38;

[0085] Calculation: 500,000 ÷ 0.38 = 131,5789.474 W.

[0086] System-enabled fuel input power (W): Pin,sys= 500,000 / 0.399 = 125,3132.832 W.

[0087] Conversion to diesel consumption (L / s): LHV = 36120000 J / L.

[0088] Reference L / s = 1315789.474 ÷ 36120000 = 0.0364 L / s.

[0089] Conversion to L / h = 0.0364 x 3600 = 131.142 L / h.

[0090] System activation L / s = 1253132.832 ÷ 36120000 = 0.0347 L / s.

[0091] Conversion to L / h = 0.0347 x 3600 = 124.897 L / h.

[0092] Fuel saving rate (%) = (131.142 - 124.897) ÷ 131.142 x 100% = 4.76%.

[0093] Conclusion (Example Two): Under the condition of ensuring 500 kW electric output, due to system modification, the effective utilization rate is increased from 38.00% to 39.90%, and the diesel consumption is reduced from 131.142 L / h to 124.897 L / h, saving about 4.76% of fuel.

[0115]

[0116] From the above, the application makes oxygen molecules "active" before entering the combustion zone by modular magnetization treatment and flow pattern control, promotes faster and more sufficient chemical reaction, and the results are: fuel consumption is reduced (3.41% and 4.76%), CO / HC / PM is significantly reduced (15%-30%), and the flame is higher (beneficial to complete combustion). At the same time, the experiment shows that NOx may increase slightly (about 2%), which is a common side effect of more complete combustion and higher flame temperature; this can be controlled by combining EGR, slight changes in combustor geometry, or exhaust aftertreatment.

[0117] From the above, the application applies a directional high gradient magnetic field to the intake flow, and if necessary, auxiliary coherent electromagnetic pulses, to oxygen molecules entering the combustion zone, so that the spin orientation of O2 molecules in the triplet ground state is locally biased and relatively redistributed. According to the coupling relationship between electron spin and chemical reaction barrier, the spin bias can reduce the pairing energy barrier required in the pairing / dissociation process, thereby increasing the probability of oxygen molecules dissociating into active oxygen atoms or forming short-lived active states with higher oxidation ability.

[0118] At the same time, the interaction of the magnetic field gradient and the local flow field also changes the collision frequency and angular momentum distribution between oxygen molecules and surrounding molecules, so that oxygen molecules are more likely to have effective collisions rather than elastic scattering during collision recombination and energy transfer. Therefore, the activity center density of the system in the reaction precursor stage (such as the instantaneous concentration of atomic oxygen or excited oxygen state) is significantly improved, thereby significantly accelerating the initial rate of the fuel-oxygen key reaction path and the cascade of chain growth steps, so that the initial state of the combustion reaction enters the high reaction rate interval faster;

[0119] Overall improvement of combustion uniformity, ignition delay and energy conversion efficiency (macroscopic / system level); the above microscopic activity improvement and magnetic field-fluid interaction together cause the "magnetized active air" entering the combustion zone to exhibit higher effective diffusivity and better mixing uniformity on a macroscopic scale. Specifically, the local ratio of oxygen and fuel molecules in the mixing section and the combustion front is inhibited, the size and duration of local oxygen-poor or oil-rich areas are shortened, the contact area of fuel particles (or droplets) and active oxygen is increased, and more uniform combustion precursor condition distribution is promoted.

[0120] On this basis, the combustion process has two key improvements: first, the ignition delay period is significantly shortened, and the combustion precursor chain reaction enters the stable growth zone earlier; second, the flame propagation rate and the spatial density of chemical reactions on the flame surface are increased, so that the combustion completes the reaction in a shorter time and smaller convolution scale, and more chemical energy is converted into available heat energy in the combustion chamber rather than escaping in the form of unburned products or particles.

[0121] Therefore, from the system point of view, the application can improve the initial state and dynamic evolution path of the combustion field by physical means under the condition of maintaining the existing combustor configuration and intake composition, thereby improving the thermal efficiency, reducing the generation of incomplete combustion products and improving the flue gas cleanliness; at the same time, the mechanism has good modular controllability (can be adjusted through field strength, residence time, flow pattern and the like), which is convenient for cooperation with closed-loop detection and combustion control strategy to achieve stable and adjustable performance optimization effect.

[0122] Although embodiments of the application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the application, the scope of which is defined by the appended claims and their equivalents.
