Q:The total amount of heat released by the fully burnt 200g coke is 60% by mass of 10kg water absorption [q coke =3.0 * 107J/kg, C water =4.2 * 103J/ (kg = C)], q:(1) how much heat is absorbed by water?(2) if the initial temperature of water is 10 degrees C, then, after absorbing heat, the temperature will rise to how much?

Dry water temperatures:Delta t=Q ceilingC water m water=3.6 x 106J4.2 x 103J/ (kg * c) * 10kgC = 85.7,At the end of a water temperature t=t0+ t=20 C +85.7 =105.7 oc,

Q:I now do a good job in the coke network editor, I would like to know more about coke

Coke is mainly used in blast furnace ironmaking and smelting of non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury and so on. In the process of blast furnace smelting, there are four kinds of functions, such as heat supply, reduction, material skeleton and carbon supply.

Q:What is the effect of coke moisture on the blast furnace?

1, a large number of high coke moisture (when the rain open storage of coke in blast furnace smelting coke), if not timely load back down, will cause a relatively large impact on the furnace, coke is better then no timely adjusting load will cause heat phenomenon.

Q:Coke is how to produce, what is its purpose?

Coke is a color of deep gray to black solid, soft; internal structure of porous, and sometimes can be six square column.

Q:What is the difference between metallurgical coke and chemical coke

Metallurgical coke, bituminous coal in the absence of air is heated to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, curing and contraction of the final stage of this process is made of coke, coking high temperature (high temperature carbonization).

Q:What are the indicators of first grade coke and the two grade coke?

The mechanical strength of the mechanical strength of ash sulfur%% volatile(crush strength M40) (abrasion strength M10)

Q:the CO reduces the iron oxide, and the part of CO burns, and the whole process will release a lot of heatCheck information, combined with the knowledge of the professional knowledge, for reference purposes only!

Coke strength index is divided into cold strength index and thermal strength indexCold strength index: M40 M25 M10

Q:What is the phosphorus content in coke

After drying, pyrolysis, melting, bonding, curing, shrinkage and other stages of the final coke, this process is called high temperature coking (high temperature carbonization)

Q:What is the use of petroleum coke

Petroleum coke, petroleum coke. Solid residues produced by high temperature coking of residual oil, residual oil or bitumen from petroleum refining.

Q:Listen to a lot of people say that steel is now coke is not true?

But at present, the iron making technology without coke has not yet been relatively mature, and it is not dominant compared with the traditional ironmaking technology. Coke industry still has development prospects.
