Q:What is the difference between the industrial analysis of coke and the industrial analysis of coal samples

Coke GB/T 1996-2003, volatile coke is the most difficult to do

Q:After the long-term use of non stick pan, oil stains can not be effectively removed, over a long period of time in the non stick coating on the formation of a layer of coke, the effect of losing non stick. As a result of this layer of coke is relatively dense and smooth, scouring cloth has been ineffective, steel ball can not be used to damage the coating, what chemical or physical methods to remove this layer of coke?

After such a toss, the coke pot was removed, but the bottom layer of the so-called "nonstick layer" are often the early damage (normally always destroyed), it is impossible to. It's like trying to get rid of terrorists.If the bottom of the layer of carbon black is not easy to erase, even if, even with good. Some people may worry about eating into the carbon poisoning, I think there is no need to worry about this. Wenchuan earthquake hero, Mr. Zhu Jianqiang, light to eat charcoal for 36 days, you can see the toxicity of carbon nothing. Moreover, after cleaning the rice cooker in the layer of carbon black has very little

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

The influence of coke moisture on blast furnace can be divided into two parts:

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

Natural coke. Coke can be obtained by high-temperature carbonization of coal:

Q:How long should it be to store coke in the open air

So, in addition to avoid rain and direct sunlight, ventilation is.Coal and coke stored in an airless environment, a large degree of risk. The temperature is too high or spontaneous combustion has been easy to stuffy.

Q:How to calculate the average particle size of coke

Broken before and after the comparison of granularity, see D50 on the line. There are many kinds of average grain size, and the calculation steps are more complicated.

Q:Distinction and distinction of cokeSoil coke, improved coke, coke machine coke do, what is the difference between

The concept of 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). By high temperature coking coke for blast furnace smelting, casting and gas generated in the process of coking. After the recovery and after the purification of coke oven gas is not only a high calorific value of fuel, and is an important raw material for organic synthesis industry. Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% were used for blast furnace ironmaking blast furnace coke, so often referred to as metallurgical coke is coke. The special cupola molten iron and coke. Coke is the main fuel cupola molten iron. It is melting charge and molten steel overheating, the support column to maintain its good permeability. Therefore, coke should be Preparation of large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough.

Q:Coke boiler belongs to coal-fired boiler

In addition, the utility model is characterized in that the utility model is used for heating and catering industry. Generally speaking, coke boiler belongs to coal fired boiler. Reason is that coke is a coal and fat coal for coke production.

Q:How to distinguish the level of coke. What is metallurgical coke

Coke type: coke is usually divided by use of metallurgical coke (including blast furnace coke, coke and iron alloy coke etc.), coke and calcium carbide with coke gasification

Q:Coke and coal is one thing

Not the same thing.Coal is often said of coal, including bituminous coal, lignite, anthracite, etc.
