Q:What is the thermal stability of coal
A variety of industrial boilers and gasification furnace has different requirements on the particle size of coal, so the method of measuring the thermal stability of coal is also different:(1) 13~25 mm level determination of lump coal. The method is to put the coal sample to muffle furnace heat of 850 DEG C during the preheating 15 minutes, calculate the percentage of the total level of sieve char; to all levels of the cumulative percentage and screen level (1, 3, 6, 13 mm) to make 100 curve. S+13 scores greater than 13 mm level char as indicators of thermal stability and thermal stability, as a percentage of S-1 curve is less than 1 mm level char as auxiliary index.
Q:How to distinguish the mechanism of charcoal is good or bad?
2 volatile matter content, depending on the carbonization temperature. According to different uses, we can burn low, medium temperature carbon, also can burn high temperature carbon. In the high temperature calcination release of CO, CO2, H2, CH4 and other volatile gaseous carbohydrate, its content is generally 12 to 20%. High temperature carbon released by the above volatile less, its content is generally less than 5%.
Q:General charcoal and activated carbon what is the difference?
The production cost of different bamboo charcoal only once the carbonization process of activated carbon, and also need an activation process, its cost is much higher than that of bamboo charcoal, about 3 - 5 times. So the selling price of the product is bamboo charcoal 3-5 times.6, and not the same as raw material consumption of activated carbon as raw material consumption and high 3-5 times than the bamboo charcoal, such as 6T (tons) of bamboo can be fired 1t bamboo charcoal, but the 3-5t can process 1t bamboo charcoal activated carbon. Of course, the coconut shell activated carbon raw material costs will be higher, but the effect is better, not a.7 shape with a barrel charcoal, bamboo charcoal in different poses and with different expressions, pieces of pieces of carbon, carbon, carbon particles, carbon powder and so on and the use of a wide range, such as carbon tube can be made into all kinds of crafts, charcoal tablets can be used for water to cook, and so on; and the active carbon is generally only powder (diameter less than 0.18mm (8mm) and the particle diameter is less than or equal to two), because there is no large activated carbon, so its application is very The limitations of the.8, the adsorption of bamboo charcoal to the pores of the main hole, and activated carbon is very different
Q:Is not all activated carbon can be placed in the refrigerator
And broke into two halves. Can achieve the same effect (steamed bread do not eat!) Or use the burnt briquettes, with a plastic bag wrapped in the refrigerator for a long time can also absorb odor. I wish you good health.
Q:What industry is washed coal
(1) anthracite (WY). Anthracite has high carbon content, low volatile yield, high density, high hardness and high ignition point. 01 anthracite for the old Anthracite; anthracite coal for the typical anthracite, anthracite coal No. 03 for the young anthracite, No. 02. Such as Beijing, Jincheng, Yangquan were 01, 02, 03 anthracite.(2) lean (PM). Coal is a high degree of coalification coal, non caking or slight caking. Non coking in layered coking furnace. Short flame, burning resistant.
Q:Effect of bamboo charcoal in bulk
Bamboo charcoal and activated carbon from1, the processing of differentBamboo charcoal only after carbonization phase, and activated carbon in addition to carbonization process, but also through the activation phase.
Q:How much is a kilo of charcoal?
To the supermarket there is the mechanism of fine packaging charcoal to buy, may be more expensive! 5 pounds of a package may be a block of 20!
Q:How to classify activated carbon
Activated carbon absorption principle is that the polluting molecules through activated carbon, into its pores, can be seen as activated carbon absorption, is a passive absorption. However, due to the lack of activated carbon molecules in the pores of their ability to adhere to pollution, there is still a constant pollution from Kong Xiyi back to the air, which is likely to cause two pollution.
Q:The necessity of power coal washing
Because in the open-pit mine coal, mixed with a lot of gangue, so it can only be counted as semi-finished products, although the semi-finished products can be used, but with the development of technology for coal utilization and coal for the user requirements increase, must have corresponding to change this state, an important measure is to change the status of the development of coal preparation technology. The more perfect, more high quality of products, reduce the ash content greatly, the loss in the tailings resources. Table 6-1-2 brief list of 1978 Liaoning province coal washery, due to the different depth of washing raw coal and ash, the relationship between the two. The commodity ash washing depth choice. Although the basic characteristic depends on the raw coal and the requirements on product quality, but the total is washing depth is smaller, reducing the ash.x0d
Q:What kind of coal is needed in a thermal power plant?
Thermal coal (steam coal).Many large thermal power plants use this kind of coal.General requirements for receiving base low heat is greater than 5000 (KCal/kg), received less than 15 base ash (%), sulfur content of as low as possible.
