It is convenient to carry, and can make eating environment comfortable.
Description
Belongs to the technical field of:
the invention belongs to the field of heat transfer heating materials, and particularly relates to a solid fuel prepared from iron ore powder and metal aluminum powder.
Background art:
most of the fuels used in the catering industry at present have the problem of smoking more or less in the using process, in order to solve the problems, the invention with application number of 00130837.8 uses solid alcohol taking sodium ethanolate stearate and the like as raw materials and easy-to-ignite harmless barbecue charcoal blocks with application number of 93107513.0, has the advantages of convenient use, small residue after combustion, convenient carrying and the like, and improves the cleanness of the fuelsfor chafing dish, tourism or picnic. However, the problem of carbon dioxide released in the combustion process exists in the use process, so that the partial air supply is insufficient when the dining table is used, the burning is incomplete or bad smell is generated, in addition, the carbon dioxide generated in the combustion process and oxygen in the room are consumed when the dining table is used indoors, frequent diners feel suffocating or other discomfort, and if the fuel which does not consume or rarely consumes oxygen and does not generate gases such as carbon dioxide and the like in the heating or combustion process exists, the dining environment can be further improved.
The invention content is as follows:
the invention aims to provide a solid fuel which can be combusted or generate heat, does not consume or hardly consumes indoor oxygen, and does not generate unclean gas such as carbon dioxide in the combustion or heat generation process.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
the solid fuel block is mainly composed of 70-85 wt% of iron ore powder, 15-30 wt% of metal aluminum powder and 3-5 wt% of binder, and the volume density of the solid fuel block is more than or equal to 1.9g/cm3Preferably 1.9 to 3g/cm3。
Wherein:
the iron ore powder is at least one of hematite powder and magnetite powder, and preferably hematite powder.
The granularity of the iron ore powder is not more than 2.0 mm.
The granularity of the metal aluminum powder is not more than 1.5 mm.
The binder is one of water glass solution or water glass powder or cement, preferably the water glass solution, and most preferably the neutral water glass solution.
Compared with the prior art, the invention has the advantages that the fuel does not consume or consumes little indoor oxygen in the combustion and use process, does not generate waste gas such as carbon dioxide and the like in the combustion or heating process, improves the dining environment, and has the advantage of not easily generating dust or other dirt in the use or carrying process.
The specific implementation scheme is as follows:
example 1
Raw materials:
hematite powder, the content of iron oxide is 90-92%, the maximum particle size is not greater than 2 mm;
the metal aluminum powder has the maximum particle size of not more than 1.5mm and the purity of 90-98 percent, and is preferably regenerated metal aluminum powder processed from waste aluminum;
the adhesive is water glass solution with specific gravity of 1.3g/cm3The modulus is 2.
Preparing materials:
taking materials according to the weight percentage, wherein the hematite powder is 75 percent, the metal aluminum powder is 25 percent, and the binder is 7 percent of the total weight of the iron ore powder and the metal aluminum powder.
Mixing materials:
the materials can be mixed manually or by mechanical equipment. When mechanical equipment is adopted for mixing materials, the raw materials and the binder can be added into mixing equipment at the same time for uniform mixing, but the method of uniformly mixing the hematite powder and the binder firstly and then adding the metal aluminum powder is preferably adopted, so that the aluminum powder can be uniformly adhered around hematite powder particles, the iron ore powder and the hematite powder are prevented from being adhered together, and the use performances such as the stability and the heat efficiency of fuel combustion are improved.
And (3) pressing and forming:
the purpose of press forming is to make the hematite powder and the metal aluminum powder contact closely, improve the stability and uniformity of fuel heating, and the other function is to increase the volume weight of the fuel, improve the portability and the preservation performance. The forming can be completed by adopting the prior art, namely, the forming is carried out by pressing after a mould is arranged on forming equipment (such as a friction pressure brick machine). The fuel after molding is in the form of a column having a through hole (preferably circular) at the centerBodies, e.g. cylinders or regular polygonal bodies, preferably flat cylinders, having a bulk density of not less than 1.9g/cm3Preferably 1.9 to 3g/cm3. The central through hole is an ignition hole and has the function of fixing an ignition position, so that fuel is ignited from the center and the ignitability is increased, thereby improving the thermal efficiency of the fuel.
And (3) drying:
the drying aims to remove moisture from the fuel and increase the strength of the fuel block, so that the fuel block is easy to ignite and is not easy to crush or fall off. The drying can be natural drying, i.e. natural storage at room temperature for 5-24 hours, or drying in a drying facility at 35-80 deg.C with flowing air or flue gas for 24 hours.
Example 2
Raw materials:
hematite powder, the oxide content of iron is 94-96%, the maximum particle size is 1.5 mm;
the metal aluminum powder has the granularity of 0.1-0.5mm and the purity of 96-98 percent, and is preferably regenerated metal aluminum powder processed from waste aluminum;
the adhesive is neutral water glass with a modulus of 3.5, and the water glass dry powder is dissolved into the water glass with a specific gravity of not less than 1.3g/cm3The solution of (1).
Preparing materials:
taking materials according to the weight percentage, wherein the hematite powder is 80 percent, the metal aluminum powder is 20 percent, and the binder is 3.5 percent of the total weight of the hematite powder and the metal aluminum powder.
The preparation method is the same as example 1.
Example 3
Raw materials:
magnetite powder, the content of iron oxide is 95-97%, and the maximum granularity is 1 mm;
metal aluminum powder with the granularity of 0.5-1mm and the purity of 97-98 percent;

magnetite powder, the content of iron oxide is 95-97%, and the maximum granularity is 1 mm;
metal aluminum powder with the granularity of 0.5-1mm and the purity of 97-98 percent;
the binder is cement.
Preparing materials:
taking materials according to the weight percentage, wherein the iron ore powder accounts for 85 percent, the metal aluminum powder accounts for 15 percent, and the binder accounts for 5 percent of the total weight of the iron ore powder and the metal aluminum powder.
The preparation method is the same as that of the example 1, but water accounting for 4-7 percent of the total weight of the iron ore powder and the metal aluminum powder is added during mixing.
Use of solid fuel:
take a cylindrical fuel as an example. When the cylindrical fuel block with the diameter of 160mm, the thickness of 30mm, the diameter of the middle hole of 5mm and the weight of 1.6kg is used, the central hole is heated by a match or a lighter or other ignition devices, when the temperature of the central hole reaches dark red or above red, the ferric oxide and the aluminum in the fuel around the hole begin to react (namely, the ferric oxide and the aluminum in the fuel around the hole begin to react) ) And expands toward the surroundings while emitting heat. One such piece of fuel can boil 3000ml of water in a beaker.
