And existing fuel stick is different, and effectively control combustion speed, promote the burning Energy Efficiency Ratio.
Summary of the invention
The object of the invention is to overcome the above problem that prior art exists, a kind of combined biomass fuel stick is provided.
For realizing a kind of combined biomass fuel stick of purpose of the present invention, include the carbon-point core, wherein: described carbon-point core is wrapped with combustion-supporting layer, is provided with combustion-supporting space in described carbon-point core, is provided with combustion-aid structure between described carbon-point core and combustion-supporting layer.
Further, above-mentioned a kind of combined biomass fuel stick, wherein, described combustion-supporting space is hollow passageway.
Further, above-mentioned a kind of combined biomass fuel stick, wherein, described combustion-aid structure is the honeycomb mesh.
Further, above-mentioned a kind of combined biomass fuel stick, wherein, described carbon-point core is bar-shaped core, and the diameter of described bar-shaped core is 1-2 centimetre, and the length of described bar-shaped core is 5-10 centimetre.
Further, above-mentioned a kind of combined biomass fuel stick, wherein, the diameter of bar-shaped core is 1.5 centimetres, the length of described bar-shaped core is 6 centimetres.
Again further, above-mentioned a kind of combined biomass fuel stick, wherein, described combustion-supporting layer outside surface is attached with thermal trough.
Adopt technical solution of the present invention, owing to being bar-shaped core, be convenient to conveying, storage, transmission, the burning aspect can be controlled automatically.Simultaneously, integral body is solid particulate, and density is large, and volume is little, and flash-point is high, stores safe ready, and cleaning is clean.And the fuel volatile matter is high, and combustioncharacteristics is good, and burn-off rate is high.Moreover sulphur content is extremely low, is only 1/20 left and right of oil fuel, need not take any desulfurization measure to get final product meet the requirement of environmental protection.Nitrogen content is extremely low, need not take any denitrification to get final product meet the requirement of environmental protection during burning.Contain ash content low, conventional cleaning apparatus can satisfy environmental requirement.
Purpose of the present invention, advantage and disadvantage will be for illustration and explanation by the non-limitative illustration of following preferential embodiment, and these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
The profile construction schematic diagram of this combined biomass of Fig. 1 fuel stick.
In figure, the implication of each Reference numeral is as follows:
The 1 combustion-supporting layer of carbon-point core 2
3 combustion-supporting space 4 honeycomb mesh
5 thermal troughs
Embodiment
A kind of combined biomass fuel stick as shown in Figure 1 includes carbon-point core 1, and its unusual part is: carbon-point core 1 of the present invention is wrapped with combustion-supporting layer 2.And, in order to improve combustionproperty, be conducive to the oxygen circulation, improve whole combustionproperty when not adding external preparation, be provided with combustion-supporting space 3 in carbon-point core 1.Correspondence is with it, combustion-supporting in order better to carry out, and reaches the effect of energy-saving and emission-reduction, is provided with combustion-aid structure between carbon-point core 1 and combustion-supporting layer 2.
In conjunction with the better embodiment of the present invention one, in order to be conducive to the mobile of Air that burn, transmit more oxygen, combustion-supporting space 3 is hollow passageway.Do not rise, consider can be conducive to carry out the flame conducting between combustion-supporting layer 2 and carbon-point core 1, promote whole efficiency of combustion, the combustion-aid structure of employing is honeycomb mesh 4.Like this, both can provide an effective passage, and simultaneously can improve certain intensity, and unnecessary subsiding can not occur and affect oxygen delivery in combustion processes.
Further, for the ease of the blanking burning, guarantee can leave airspace when each fuel stick is in contact with one another, carbon-point core 1 of the present invention is bar-shaped core.Specifically, in order to adapt to common cooking stove specification, coordinate simultaneously the model of press machine, the diameter of bar-shaped core is 1-2 centimetre, and the length of bar-shaped core is 5-10 centimetre.And, consider the best proportioning of making and using, the diameter of the bar-shaped core of employing is 1.5 centimetres, corresponding bar-shaped core length is 6 centimetres.
Moreover, consider the facility of lighting, in order to be conducive to the quick distribution of flare, realize perfect combustion, combustion-supporting layer 2 outside surface are attached with thermal trough 5.
From implementation process of the present invention, the carbon-point core carbon content few (being about 45-50%) of employing, the content of fixed carbon low (being about 16%) especially, when therefore burning, carbon emission is low.Combustion-supporting layer contains hydrogen content many (being about 4-5%), volatile matter high (being about 70%), so combustioncharacteristics is good.Simultaneously, oxygen level high (approximately 35-40%).The biomass fuel oxygen level is significantly more than mineral coal, and it makes biomass fuel be easy to ignite.And for the present invention, whole sulphur: sulphur content is less than 0.18%, and environmental protection characteristic is good, during burning, flue gas desulfurization (FGD) unit needn't be set.Nitrogen content is less than 0.8%, during burning, equipment for denitrifying flue gas needn't be set.
Further, it is main as raw material that carbon-point core of the present invention adopts high-quality lignocellulosic biomass, contains grey split pole low, only has 1.5-3%.Simultaneously, density: 1～1.2, calorific value 4300～51000Kcal/Kg, approximately 2-2.5kgBMF.Like this, can effectively substitute 1Kg oil fuel or 1 cubic natural gas.In other words, integral body of the present invention is by flammable matter, inorganics and water composition, mainly contains the elements such as carbon (C), hydrogen (H), oxygen (O) and a small amount of nitrogen (N), sulphur (S), and contains ash content and moisture.In the reality preparation, the carbon-point core can from agriculture and forestry organic waste material, use and disregard energy consumption, so per Unit GDP Energy Consumption be 0.And can satisfy " 0 " discharging: the CO2 of biomass combustion discharging is identical with the CO2 that it absorbs in process of growth, and has substituted fossil energy, has reduced clean discharging, and according to Kyoto Protocol mechanism, biomass fuel CO2 is ecological " 0 " discharging.
By above-mentioned character express and can finding out by reference to the accompanying drawings, after adopting the present invention, owing to being bar-shaped core, be convenient to conveying, storage, transmission, the burning aspect can be controlled automatically.Simultaneously, integral body is solid particulate, and density is large, and volume is little, and flash-point is high, stores safe ready, and cleaning is clean.And the fuel volatile matter is high, and combustioncharacteristics is good, and burn-off rate is high.Moreover sulphur content is extremely low, is only 1/20 left and right of oil fuel, need not take any desulfurization measure to get final product meet the requirement of environmental protection.Nitrogen content is extremely low, need not take any denitrification to get final product meet the requirement of environmental protection during burning.Contain ash content low, conventional cleaning apparatus can satisfy environmental requirement.
Certainly, above is only concrete exemplary applications of the present invention, and protection scope of the present invention is not constituted any limitation.In addition to the implementation, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, within all dropping on the present invention's scope required for protection.
