Example Embodiment

[0020] Example 1: The weight of each component in the batching is: 690 kg of compressed biomass particles (accounting for 69%), 250 kg of loess (accounting for 25%), and 60 kg of water (accounting for 6%). Corn stalks (or stems, stems, branches, leaves, roots, husks, skins, and shavings of one or more mixtures of grass and woody plants) are crushed in a crusher. The diameter of the crushed material is preferably smaller than 3mm. Then the scraps are put into a pellet molding machine for extrusion molding to obtain compressed pellets of biomass. The compressed particles have a diameter of 0.15-1.5 cm and a length of 0.5-5 cm. The compactness requires 13 minutes of watering, and the particles do not expand. The production method of the present invention is to mix 650 kilograms of compressed pellets of biomass, 250 kilograms of loess, and 100 kilograms of water, stir, and form the fuel in the shape of briquettes (or spread out into blocks) by extrusion molding by a molding machine. D...

Example Embodiment

[0021] Example 2: The weight of each component in the batching is: 700 kg (70%) of compressed particles of organic matter of urban and rural household garbage, 180 kg (18%) of loess, and 120 kg (12%) of water. The organic matter of urban and rural household garbage such as waste plastics and packaging materials are crushed in a crusher, and the diameter of the scraps is preferably less than 3mm. Then the scraps are put into a pellet molding machine for extrusion molding to obtain compressed pellets of organic matter from urban and rural household garbage. The compressed particles have a diameter of 0.2-1.5 cm and a length of 0.3-5 cm. The production method of the present invention is to mix 700 kilograms of compressed particles of urban and rural household waste organic matter, 180 kilograms of loess, and 120 kilograms of water, stir, and extrude them by a molding machine to form honeycomb briquettes (or disperse them to form blocks). The fuel is dried to obtain solid fuel.

Example Embodiment

[0022] Example 3: The weight of each component during the batching is: industrial waste residue organic material (it can be one or several mixtures of furfural residue, brewing residue, oily mud, and scrap rubber). This example is Two mixtures of furfural residue and scrap rubber) 690 kg (69%), 160 kg loess (16%), and 150 kg water (15%). The production method of the present invention is to pulverize waste rubber in a pulverizer to obtain scraps of waste rubber. Mix 690 kilograms of furfural slag and scraps of waste rubber, 160 kilograms of loess, and 150 kilograms of water, stir, and extrude them by a molding machine to form a honeycomb-shaped (or spread out into a block) fuel. Dry, solid fuel is obtained.

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...
