Abstract
The flyash briquette is produced by using the raw material including coal, flyash and clay and the material composition by weight is coal 35-50%, flyash 35-50% and clay 10-15%. After the above materials are mixed thoroughly, water in the amount of 10-20% material weight is added, and through mixing and pressing formation, the flyash briquette is produced. The method is simple and practical and the briquette product has strong fire and long burning period.
Description
The present invention relates to a kind of production method of moulded coal, particularly relate to a kind of production method of briquet from powder coal ash.
Often use the moulded coal burning in industry and daily life, common moulded coal is to be main raw material with the high-quality anthracite, adds a certain amount of clay and lime again and makes, and needs to consume a large amount of fat coals; And a large amount of flyash that produce in combustion processes cause environmental pollution, have a small amount of flyash to be used to produce cement, refractory materials, brickmaking etc. at present.Chinese patent CN1055949A has introduced a kind of method with flyash preparation smokeless fuel, it is characterized in that 3～5 parts of flyash, and 3～4 parts of slags or coal gangue add 15～25% water of above raw material weight summation again, after stirring, grind the type of making.Though flyash has certain calorific value, can make fuel, but calorific value is low, and slag and coal gangue are low heat value too, therefore, cooperate the moulded coal firepower of producing little with these two kinds of raw materials, and thermo-efficiency is low, can't trouble-free burning, so can not be used for industrial and daily life.
The object of the present invention is to provide a kind of production method of making the briquet from powder coal ash of raw material with flyash instead of part fire coal.
The production method of briquet from powder coal ash of the present invention is, coal dust with 35～50% (weight), 35～50% (weight) flyash, 10～15% (weight) clay is after mixing, more by weight, raw material: the ratio of water=1: 0.1～0.2 adds entry, after stirring,, make briquet from powder coal ash through briquette shaper compression moulding.Wherein coal dust can be the mixture of bituminous coal or hard coal or various coals, and the granularity of coal dust, clay is controlled at 30～70 orders, more helps raw material and mixes, and improves the efficiency of combustion of moulded coal.
The advantage 1 of the production method of briquet from powder coal ash of the present invention) be that production technique is simple, easy to utilize.2) the products obtained therefrom moulded coal is long combustion time, and combusting firepower is strong, and cost is low, and under equal conditions than long 1～1.5 times of common moulded coal, combusting firepower is strong 0.5～1 times, and cost is per ton to reduce by 35～50%.3) save energy, the protection environment reduces and pollutes.
Describe the embodiment of the invention below in detail.
Embodiment 1: with 50 kilograms in granularity 40 purpose bituminous coal, after 38 kilograms in flyash, 12 kilograms of granularity 50 purpose clays mix, add 15 kg of water, stir, use the briquette shaper moulding, make briquet from powder coal ash.
Embodiment 2: with 40 kilograms in granularity 60 purpose hard coals, after 45 kilograms in flyash, 15 kilograms of granularity 60 purpose clays mix, add 17 kg of water, stir, use the briquette shaper moulding, make briquet from powder coal ash.
Claims (2)
1, a kind of production method of briquet from powder coal ash, raw material comprises coal and flyash, the weight proportion that it is characterized in that each component is a coal 35～50%, flyash 35～50%, clay 10～15%, after mixing, raw material by weight again: the ratio of water=1: 0.1～0.2 adds entry, after stirring, compression moulding.
2, the production method of briquet from powder coal ash as claimed in claim 1, the granularity that it is characterized in that coal and clay is 30～70 orders.
