Abstract
The invention relates to a method for moulding smokeless fuel by mixing pulverized coal ash and bituminite or brown coal or peat according to the compounding ratio. The pulverized coal ash or the bituminite or the brown coal or the peat are mixed according to the volatilization productive rate, and then an amount of additive is added in order to control the volatilization productive rate of the compounded mix material to be less than 15%. The various shapes of smokeless fuel can be moulded after adding water to uniformly mix the mix material. The smokeless fuel has the characteristics of high activity of reaction, favorable effect, strong fire power, no smoke, low cost, high economic benefit, etc.
Description
The present invention utilizes flyash and bituminous coal, brown coal or peat proportioning, manufactures the method for moulding smokeless fuel.
For solve coal firing boiler in combustion processes to atmospheric pollution, coal firing boiler all assembles dust removal installation.Pounce on the flyash (flue dust) that collects through dust removal installation, calorific value is all arranged, still can be used as fuel.Except that a spot of flyash was used to produce cement, concrete, refractory materials, glass, plastics, rubber, senior acid-proof coating and brickmaking, most of waste residue of pressing was handled at present, and contaminate environment wastes energy.
The objective of the invention is flyash is joined in bituminous coal, brown coal or the peat, add an amount of additive, manufacture the moulding smokeless fuel.Can utilize refuse, reduce environmental pollution, can develop the resource of smokeless fuel again.
Invention is achieved in that
The fugitive constituent productive rate height of bituminous coal, brown coal or peat owing to incomplete combustion, produces black smoke in combustion processes.The fugitive constituent productive rate of flyash is low, and the reactive behavior height has certain calorific value.Flyash (quality of the type of furnace, combustion system, feed coal kind and dedusting method decision flyash) and bituminous coal, brown coal or peat proportioning with different mass, add an amount of additive mixing, compound still has certain fugitive constituent and reactive behavior, and smokeless fuel is made in compression moulding.
Present method is controlled the fugitive constituent productive rate just with flyash and coal proportioning, so method is simple, and easy handling.The smokeless fuel that this method is made has high reaction activity and high, and combustionvelocity is fast, the intensity of fire height, and combustion efficacy is good, and is smokeless substantially, and lime-ash carbon residue is low, less investment, high efficiency.
The specific embodiment of invention is as follows:
Raw coal (bituminous coal, brown coal or peat) is broken less than 2 millimeters (or directly using fine coal), analyze fugitive constituent productive rate and calorific value, measure the fugitive constituent productive rate and the calorific value of flyash simultaneously, press analytical results with coal and flyash proportion, add an amount of additive (binding agent etc.), the fugitive constituent productive rate that makes compound after the proportioning is below 15%.The calorific value of compound can be determined according to the purposes of making moulded coal, needs the fuel with high heating value, the feed coal and the flyash of selection high heating value.The system domestic fuel gets final product with common feed coal and flyash.Compound after the proportioning is added an amount of water stir,, make the smokeless fuel of different shape through extrusion forming.
According to present method requirement, available single flyash proportion of planting bituminous coal, brown coal or peat and different mass, also available bituminous coal, brown coal, peat etc. mix coal and flyash proportion, and control fugitive constituent productive rate all can be made smokeless fuel below 15%.Can reduce direct fire coal to the pollution to environment of environment and flyash, variable again refuse is the energy.
Claims (1)
1, a kind of with the be mixed method of the smokeless fuel made of coal ash (fuel boiler fly-ash separator capture flue dust) and bituminous coal, brown coal, peat, it is characterized in that fugitive constituent productive rate by flyash, bituminous coal, brown coal and peat, be mixed with bituminous coal, brown coal, peat respectively with flyash, or with the preparation of the compound of bituminous coal, brown coal and peat, the fugitive constituent productive rate of control mixed ingredients, make it below 15%, add an amount of additive mixing, be pressed into anthracite briquette.
