Abstract
The invention discloses a kind of production method of briquet from powder coal ash.It adds the water of the 15%-20% weight of three of the above raw material weight summation, agitated uniform rear calendering forming using 3-5 parts of flyash and 3-4 parts of colm of crushing, 3-4 parts of slag or gangue.Moulded coal production method of the present invention, can save substantial amounts of fat coal and clay, and raw materials used is twice laid, and the moulded coal after burning has certain intensity, non-breakable, non-secondary pollution, and in combustion smokelessly, cost is less than any moulded coal.Its production method is simple and easy to apply, easy to utilize.
Description
Technical field
The present invention relates to the utilization of fly ash technology that steam power plant is discharged, specifically a kind of method for producing moulded coal as primary raw material with flyash.
Background technology
For in daily life, the common moulded coal that people use or see, it is raw material usually using high-quality anthracite, a small amount of bituminous coal, clay and calcium oxide is equipped with to be made, he consumes substantial amounts of fat coal and clay, due to clay large usage quantity, is destroyed by the ecological balance at the place of fetching earth, the cost of its moulded coal is also to be growing on and on, and incomplete combustion.
Technology contents
The present invention is directed to disadvantages mentioned above, there is provided one kind can save fat coal, is not required to plus clay, the moulded coal manufacture method of low cost.
Task of the invention is done in such a way that it using 3-5 parts of flyash and 3-4 parts of colm of crushing, 3-4 parts of slag or gangue, adds the water of the 15%-20% weight of three of the above raw material weight summation, agitated uniform rear calendering forming.
Moulded coal production method of the present invention, can save substantial amounts of fat coal and clay, and raw materials used is twice laid, and the moulded coal after burning has certain intensity, non-breakable, non-secondary pollution, and in combustion smokelessly, cost is less than any moulded coal.Its production method is simple and easy to apply, easy to utilize.
Colm, slag or gangue described in the present invention are both needed to be crushed to 30-60 mesh, and colm is lignite or coal slime (coal slime is not required to crush).
Specific embodiment
Embodiment 1：
3 parts of lignite and 3 parts of gangues are size-reduced to 30 mesh, add 4 parts of flyash and be made of calendering forming after the three kinds of water of raw material gross weight than 20% stir.
Embodiment 2：
3 parts of gangues are size-reduced to 30 mesh, then 3 parts of coal slimes and 3 parts of flyash are taken, it is subsequently adding by above-mentioned water of three kinds of raw material weights than 20%, agitated uniform, calendering forming.
Claims (2)
1. a kind of production method of briquet from powder coal ash, it is characterised in that it adds the water of the 15%-20% weight of three of the above raw material weight summation using 3-5 part flyash and 3-4 part colm of crushing, 3-4 parts of slag or gangue, agitated uniformly calendering forming afterwards.
2. briquet from powder coal ash production method according to claim 1, it is characterised in that described colm is lignite or coal slime.
