Further, above-mentioned a kind of combined biomass fuel brick, wherein, described center carbon piece is the flats core, and the diameter of described flats core is 1-3 centimetre, and the height of described flats core is 2-5 centimetre.
Further, above-mentioned a kind of combined biomass fuel brick, wherein, the diameter of flats core is 2 centimetres, the height of described flats core is 4 centimetres.
Again further, above-mentioned a kind of combined biomass fuel brick, wherein, described combustion-supporting layer outside surface offers thermal trough.
Adopt technical solution of the present invention, owing to being the flats 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
Fig. 1 is that profile is the fuel brick body configuration schematic diagram of rectangular parallelepiped;
Fig. 2 is that profile is columniform fuel brick body configuration schematic diagram;
The profile construction schematic diagram of this a kind of combined biomass fuel brick of Fig. 3.
In figure, the implication of each Reference numeral is as follows:
The 1 combustion-supporting layer of center carbon piece 2
3 combustion-supporting space 4 honeycomb mesh
5 thermal troughs
Embodiment
A kind of combined biomass fuel brick as Figure 1-3 includes center carbon piece 1, and its unusual part is: center of the present invention carbon piece 1 is wrapped with combustion-supporting layer, consists of fuel brick body 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 center carbon piece 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 center carbon piece 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 center carbon piece 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, center of the present invention carbon piece 1 is the flats core.Specifically, in order to adapt to common cooking stove specification, coordinate simultaneously the model of press machine, the diameter of flats core is 1-3 centimetre, and the height of flats core is 2-5 centimetre.And, consider the best proportioning of making and using, the diameter of the flats core of employing is 2 centimetres, corresponding flats core height is 4 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 offer thermal trough 5.
From implementation process of the present invention, the center carbon piece carbon content few (being about 45-50%) of employing, the content of fixed carbon low (being about 14%) 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 center of the present invention carbon piece adopts high-quality lignocellulosic biomass, contains grey split pole low, only has 2-3%.Simultaneously, density: 1～1.2, calorific value 4300～5100Kcal/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, center carbon piece 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 the flats 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.
