Description
One, technical field
The present invention relates to a kind of preparation method of high-quality circle bar formula dimerization fuel moulded coal, specifically a kind of method of manufacture that low-grade fuels such as dimerization fuel, conny, coal slime, breeze, brown coal, coal gangue, biomass is modulated into the high-quality circle bar formula dimerization fuel moulded coal of industry, living needs.
Two, background technology
Clearly propose in country's " 12 " development program " outline " to accelerate the resources circulation industry development, strengthen mineral resources comprehensive utilization, encourage the industry cyclic utilization of waste, promote the recycling economy typical module.
So-called dimerization fuel is meant through multi mineral is mixed, and under external high temperature, causes it solid state reaction takes place each other, and discharge the material of huge energy.
Dimerization fuel is that a kind of to utilize industrial residues such as red mud, iron (gold) mine tailing, desulfurated plaster be the New-type fuel that raw material is composited, and relates to solid state reaction energy conversion technique field.
So-called high-quality garden bar shaped dimerization fuel moulded coal is the method for manufacture that powder low-grade fuels such as dimerization fuel, conny, coal slime, breeze, brown coal, coal gangue, biomass is modulated into the high-quality circle bar formula dimerization fuel moulded coal of industry, living needs.
China is that a few energy is one of main country with the coal in the world, also is maximum in the world consumption of coal state.Compare with countries in the world, the Energy resources of China are more nervous; China is populous nation and is about to become world-class economic giant; But not corresponding Energy resources big countries; Imbalance between supply and demand is very big, and the shortage of fuel is just very serious now, for this reason; From now on just should active research and exploitation make low-grade fuel become high-grade fuel, give full play to the effect of fuel.
Surplus the Industrial Boiler more than 100 ten thousand of the whole nation, surplus the Industrial Stoves more than 50 ten thousand, and a large amount of resident living uses stove, and wherein major part belongs to grate furnace and fluidized-bed combustion boiler, all only is suitable for using block coal.Because of the lump coal productive rate descends, price is constantly soaring, can't satisfy the needs of industrial lump coal.Outside the coal carbon removal soon, also have rudimentary fuel such as a large amount of connys, coal slime, breeze, brown coal, coal gangue, biomass to await development to utilize to make it to become the useful quality block moulded coal fuel of industry, widen energy sources; Reduce and pollute; Reduce the industrial production cost, increase economic benefit and social benefit, utilize tackiness agent and molding device that above-mentioned rudimentary fuel is processed block moulded coal fuel moulded coal; These low-grade fuels are fully utilized, for energy-saving and emission-reduction are contributed.
Three,
