Description
Technical field
The present invention relates to ethanol combustors, and in particular to a kind of improvement of the structure of ethanol combustor.
Background technology
Methanol fuel is set to clean energy resource by country and encourages to promote in automobile and burning industry, first on existing market
Alcohol cooking range table application behind restaurant, hotel as fuel also has and is applied on boiler.Methanol application technology in burning industry has
Two kinds, one is spray burning, another kind is vaporization combustion.Spray burning is exactly that methanol is constantly allowed methanol stream with a conduit
A very long reddish yellow flame is blown out with wind turbine after being lighted at bocca, belongs to particle burning.Vaporization combustion is exactly first handle
Methanol becomes gas reburning burning, and it is methanol is flowed into burner point to use wind turbine to blow to have a kind of burner in the market, there is one on burner
A bocca is cylinder iron to cast, centre be it is empty allow methanol to be flowed through from this, bocca cast iron just will produce high temperature for a moment for burning
Burning again after the methanol gasifying flowed through from this（64 ° of methanol can vaporize）, the length of flame that vaporization combustion sprays is than atomization
It is short, flame temperature is also higher than atomization, therefore is also saved with fuel.Either atomization or vaporization combustion, due to first
Alcohol easily occurs wash rice carbon at 400-600 °, so often there is blocking sprayer phenomenon；In addition, atomization and vaporization combustion all be unable to do without wind
Machine aided fires, and blowing fan delivery increases when needing firepower, and wind speed raising can cause part methanol to have little time burning to be discharged in air,
Here it is the peppery eyes of always love that cooks often say, and calorific value is relatively low.
The steam of first alcohol and water is in 2.2mpa and by dedicated catalyst conversion to occur under the conditions of higher than 260 DEG C anti-
It answers, generates the hydrogen and carbon dioxide of chemical ratios, chemical equation CH4O+H20 → CO2+H2.Due to combustion of hydrogen calorific value
High and abundant, if methanol decomposition can be allowed to go out hydrogen and applied in reality, that will be significantly energy saving and very environmentally friendly.It can be due to
Price, use condition and the service life of catalyst for preparing hydrogen determine that it can only can be applied in a large amount of purifying hydrogen of hydrogen, so restricting
It and is applied on automobile and burning industry.
But it is exactly that can equally be cracked into hydrogen and carbon dioxide in 800 DEG C of high temperature or more that methanol, which also has another property,
That is methanol gas, which is placed on the place more than 800 DEG C, can crack out the gaseous mixture of a large amount of hydrogen, such gaseous mixture
Blazing up can increase substantially than the combustion heat value of methanol gas, and what is be discharged is vapor and carbon dioxide, super ring
It protects.
Based on this, Patent No. 201320685066.X discloses a kind of Pintsch process burner, mainly include bottom plate,
Pipe sleeve, cracking tube, heater, ignition electrode, temperature sensor, nozzle and controller, bottom plate constitute combustion barrel, feature with pipe sleeve
It is：Combustion barrel inner circumferential is equipped with two layers of spiral pipes, and internal layer is cracking tube, and outer layer is generating tube, is equipped with and adds between two layers of spiral pipes
The outlet of hot device, helix tube is connected by connecting tube with the nozzle in combustion barrel, and nozzle is nearby equipped with ignition electrode；Its it is opposite with
Atomization on existing market is compared with gasified methanol burner, and advantage is that methanol decomposition is gone out hydrogen partial modifying combustion to improve
Calorific value, it is energy saving, and exhaust gas component only has carbon dioxide and vapor, clean environment firendly.But defect is：Since heater is placed in two layers
Between helix tube, therefore processing program is cumbersome, and production efficiency is relatively low, and production cost is relatively high.
Invention content
The present invention aiming at above-mentioned technical problem, provide it is a kind of it is easy to process, cost is relatively low and lytic effect is more abundant
The Pintsch process burner with external cracking tube.
To achieve the above object, the present invention adopts the following technical scheme that, the invention mainly comprises combustion barrel, ignition electrode and sprays
Head, combustion barrel are made of bottom plate, pipe sleeve, the expects pipe that is located in pipe sleeve, and nozzle is located at the intermediate position of combustion barrel by bottom plate, spray
Head is nearby equipped with ignition electrode, and structural feature is that expects pipe is divided into inner tube and outer tube, outer tube peripheral hardware having heaters, internal layer
The outlet of pipe is connected with extension cracking tube, and extension cracking tube is located at the outside of combustion barrel inner wall, and the outlet of extension cracking tube passes through
Connecting tube is connect with the nozzle in combustion barrel.
It is further improved, outer tube is cast together with heater molten metal, preferably uses molten aluminum or copper liquid or aluminium alloy casting
Together.
It is further improved, expects pipe is divided into internal layer helix tube and outer layer helix tube, and the outlet of internal layer helix tube is connected with extension
Cracking tube.
It is further improved, expects pipe is divided into internal layer corrugated pipes and outer layer corrugated pipes, and the outlet of internal layer corrugated pipes is connected with extension
Cracking tube.
It is further improved, expects pipe is to be bent pipe in the arc-shaped by an expects pipe, and the outlet of expects pipe is connected with extension cracking tube.
It is further improved, expects pipe is to be bent waviness pipe by an expects pipe, and the outlet of expects pipe is connected with extension cracking tube.
Preferably, the cross sectional shape of extension cracking tube is that spiral gradient plane or cone gradual change plane or spiral tubbiness are flat
Face.
Preferably, extension cracking tube is entwined by corrugated pipes.
It is further improved, extension cracking tube is located at the outside of combustion barrel inner wall and the upper area of combustion barrel simultaneously.
Beneficial effects of the present invention：
1, easy to process：Since heating tube is located at outside outer tube, rather than among inner tube and outer tube, so processing hand
Continuous simplicity, production efficiency can also improve, and cost can also reduce；
2, energy saving and efficient：Due to being additionally arranged extension cracking tube, that is, it being additionally arranged cracking zone, outer tube is preheated for vaporizing,
Inner tube is Pintsch process area for vaporization and fraction cracked gas, extension cracking tube, keeps the reaction of its internal cleavage more abundant,
Calorific value is greatly improved, temperature can reach 1550 DEG C, so energy saving and efficient；
3, emission reduction environmental protection：There are most of hydrogen components when burning, so burning is more abundant, the ingredient after burning is single to be exactly
Water and carbon dioxide, super environmental protection, uncontaminated gases discharge.
