Embodiment 1

[0020] Embodiment 1: The weight of each component during batching is respectively: 690 kilograms (accounting for 69%) of the compressed particle of biomass, 250 kilograms (accounting for 25%) of loess, 60 kilograms (accounting for 6%) of water. Grind corn stalks (or stems, stems, branches, leaves, roots, husks, skins, and shavings of grasses and woody plants or one or more mixtures thereof) in a grinder, and the diameter of the crushed materials is preferably less than 3mm. Then put the crushed material into the granule molding machine for extrusion molding, that is, the compressed granules of biomass are obtained. The compressed granules have a diameter of 0.15-1.5 cm and a length of 0.5-5 cm, and the compactness requires water for 13 minutes without swelling of the granules. The preparation method of the present invention is to mix the compressed particles of 650 kilograms of biomass, 250 kilograms of loess, and 100 kilograms of water, stir, extrude and form the fuel of hon...

Embodiment 2

[0021] Embodiment 2: the weight of each component during batching is respectively: 700 kilograms (accounting for 70%) of the compressed granule of urban and rural household refuse organic matter, 180 kilograms (accounting for 18%) of loess, 120 kilograms (accounting for 12%) of water. The organic waste of urban and rural residents such as waste plastics and packaging materials is crushed in the shredder, and the diameter of the shredded materials is preferably less than 3mm. Then put the crushed material into the granule molding machine for extrusion molding, that is, the compressed granules of urban and rural domestic waste organic matter are obtained. The compressed particles have a diameter of 0.2-1.5 cm and a length of 0.3-5 cm. The preparation method of the present invention is to mix 700 kilograms of compressed particles of urban and rural household garbage organic matter, 180 kilograms of loess, and 120 kilograms of water, stir, and extrude into honeycomb coal shape (or...

Embodiment 3

[0022] Embodiment 3: the weight of each component during batching is respectively: industrial waste slag organic matter scrap (can be one or more mixtures of the scrap of furfural residue, brewing residue, oily mud, waste rubber, the present embodiment is 690 kilograms of furfural slag and scraps of waste rubber) (accounting for 69%), 160 kilograms of loess (accounting for 16%), and 150 kilograms of water (accounting for 15%). The preparation method of the present invention is to crush waste rubber in a pulverizer to obtain scrap rubber. Mix 690 kg of furfural slag, scraps of waste rubber, 160 kg of loess, and 150 kg of water, stir, extrude and form a fuel in the shape of honeycomb coal (or disperse and spread it into blocks) by a molding machine, and let it dry in the air. Dry to get solid fuel.

Abstract

A fuel as the substitute of coal contains X (40-80%), yellow clay (10-40%), water (5-25%), coal gangue (0-40%) and fly ash (0-40%). Said "X" is the compressed particles of biomass, organic life garbage, organic industrial dregs, or their mixture. Its preparing process is also disclosed. Its advantages are high heat value, long burning time and low cost.

Description

technical field [0001] The present invention relates to a kind of solid fuel, especially a kind of fuel which replaces domestic and industrial coal. The invention also relates to a method for making the fuel. Background technique [0002] At present, there are many technologies related to fuels that can replace domestic or industrial coal, and there are many literature reports on this technology. For example, CN1353171A discloses a kind of environmental protection particle fuel, and its raw material includes the scrap of various plant straws, water, calcium bicarbonate, combustion improver, binding agent. Another example is CN1312351A which discloses a solid fuel made of fly ash and plastic and its preparation method. It is a solid fuel made of fly ash, polyethylene plastic and biofuel, heated, mixed and extruded. fuel. At present, the fuel to replace civilian or industrial coal needs to be equipped with a special stove. The fuel is prone to sm...
