specific Embodiment approach
[0021] Its preferred embodiment of the refuse-derived fuel of the present invention comprises the following raw materials:
[0022] Domestic garbage 70-90 parts, can be 70, 75, 80, 85, 90 parts, etc.;
[0023] 10-30 parts of coal, can be 10, 15, 20, 25, 30 parts, etc.;
[0024] Calcium-containing substances 0.1-1 part, can be 0.1, 0.3, 0.5, 0.7, 1 part, etc.
[0025] The components of the above raw materials are parts by weight.
[0026] According to needs, the garbage-derived fuel can be in the form of pellets, blocks or honeycombs.
[0027] Its preferred embodiment of the preparation method of garbage derived fuel of the present invention is,
[0028] Using MSW as raw material, it is sorted, crushed, mixed, and by adding calcium-containing substances and coal powder, uniformly mixed and formed, and finally solid RDF is obtained. The RDF prepared by the invention is suitable for use in combustion, pyrolysis and gasification, and realizes efficient and clean energy utiliza...
specific Embodiment 1
[0037] The garbage-derived fuel is composed of the following components by weight: 89.5 parts by weight of pulverized domestic garbage, 10 parts by weight of coal powder, and 0.5 parts by weight of calcium-containing substances. The above-mentioned raw materials are sent to the mixer for mixing and mixing, and then sent to the double-roll forming machine, and finally processed into egg-shaped dense RDF with a particle size of 25mm.
[0038] After testing, the calorific value Q of the prepared garbage-derived fuel net,ad It is 9716.3kJ / kg, which is 30% higher than that of MSW; the bulk density is significantly increased, which is 2360kg / m 3 , is 5.5 times that of MSW; under the molding pressure of 15MPa, the cold strength exceeds 66%, which is higher than the strength of MSW under the same pressure (59%), and the hot strength TS +6 and TS +3 5% and 20%, respectively, which are lower than the strength of MSW under the same pressure (11% and 31%); the crucible expansion number ...
specific Embodiment 2
[0040] The garbage-derived fuel is composed of the following components by weight: 79.5 parts by weight of pulverized domestic garbage, 20 parts by weight of coal powder, and 0.5 parts by weight of calcium-containing substances. The above-mentioned raw materials are sent to the mixer for mixing and mixing, and then sent to the double-roll forming machine, and finally processed into egg-shaped dense RDF with a particle size of 25mm.
[0041] After testing, the calorific value Q of the prepared garbage-derived fuel net,ad It is 11960.2kJ / kg, which is 60% higher than that of MSW; the bulk density is significantly increased, which is 2360kg / m 3 , is 5.5 times that of MSW; under the molding pressure of 15MPa, the cold strength exceeds 90%, which is much higher than the strength of MSW under the same pressure (59%), and the hot strength TS +6 and TS +3 18% and 40%, respectively, which are higher than the strength of MSW under the same pressure (11% and 31%); the crucible expansion...
