Which, fly ash or coal gangue, has the better internal combustion effect in a brickyard?

Which, fly ash or coal gangue, is better for internal combustion in a brickyard?

Red bricks, right?

That it s It is fly ash or coal gangue, provided that the calorific value is not less than 800 calories, which Choose the one that is cheaper.

Additionally, using fly ash for internal combustion can improve the smoothness of bricks and give them a better appearance. Once the coal matrix has burned, a few small holes will remain on the bricks.

Which is better for making bricks, coal ash or coal gangue from fertilizer plant?

Coal gangue

How much fly ash is produced from one meal of coal gangue?

Are you talking? on the by-product of the combustion of a ton of coal gangue? Quantity of fly ash? Typically this is approx.iron 0.7 to 0.8 ton.

How to produce silicon fertilizer from coal gangue fly ash

This question is easy to ask but not easy to solve. Simply put, the silicon in coal gangue fly ash cannot be. used by crops. Absorption requires activation. This activation process is a chemical process. Generally speaking, this chemical process is relatively expensive. is activated silicon. Acidic salt can be directly used as silicon fertilizer.

Can gangue mounds from coal mines and fly ash from power plants be mixed?

According to the provisions of the “Technical safety regulations for settling basins” (AQ2006-2005): the gangue from your mine is sorted waste and must be residue. For mining or industrial residues, if the gangue field or gangue mount is made up of a damto intercept the mouth of a valley or an enclosure, the provisions of the “Technical safety regulations for tailings ponds” (AQ2006-2005) must be followed. Please refer to the definition of tailings pond in the “Regulations”:

Tailings pond

means a dam formed to intercept the mouth of a valley or an enclosure used for storing metal and non-metallic mines. Place where tailings or industrial waste is dumped after ore separation.

The above opinions are personal opinions, please consult the Coal Mine Safety Supervision Office directly.

Coal gangue, coal slag, coal ash, fly ash, water slag, what is the difference and what is its use

Coal gangue is a stone mixed with coal with a relatively low calorific value.

Coal slag is the residue somassive lides resulting from the combustion of coal.

Coal ash is the fine solid residue produced by the flue gas dust removal system after the combustion of coal.

Fly ash refers specifically to the fine-grained solid residue produced by coal-fired power plants that is soaked by water.

Water slag is the granular solid residue produced by molten slag exiting the blast furnace during iron making in the blast furnace and quenched by water. It is not certain whether the coal industry also uses the concept of water residue.

Can non-burning bricks be made with only fly ash, coal gangue, lime slag and cement? There is no river sand and gravel

No, river sand and gravel play the role of aggregates. Without it, the strength of the bricks can reach the standard, but the reBending strength is low, which means that the bricks are relatively fragile. .

In addition, there is another point here: raw materials such as coal gangue must be burned or spontaneously ignited before they can be used to make Burned bricks cannot be used otherwise.

What materials are cheap, such as fly ash, slag, coal gangue, sand and stone powder?

Not necessarily, it mainly depends on local market conditions and generally follows market conditions. I don't know your specific usage. Generally, if you are making building materials, it is recommended to use fly ash and stone powder to produce standard bricks, porous household bricks, small hollow blocks, etc.

Medium coal gangue for brick factory

Internal combustion is the residue producedby power plants. The fly ash we are talking about has nothing to do with coal and internal combustion. When the medium coal is crushed, it is used. to make it combustible and burn better. The gangue does not burn.

What is the difference between fly ash produced by coal gangue power plants and fly ash produced by ordinary thermal power plants

The ingredients are the same, but the calorific value fly ash? produced by coal gangue is relatively low. After an ordinary small power plant uses raw coal to generate electricity, the fly ash still has a calorific value of 1,300 calories. In a large power plant, the remaining fly ash only has a calorific value of about 700 after complete combustion.

The remaining calorific value after the production of electricity with the gangue ist lower and the impurity content in fly ash is higher.
