1. Structure of Metallurgical Coke of NUT COKE of 10 to 30mm Description:
Coke is made by high temperature metallurgical coke for blast furnace smelting, casting and gasification. Occurring in the process of coking after recovery and purification of coke oven gas is a high calorific value of fuel, is an important industrial raw material in organic synthesis.
The physical properties of the coke with room temperature mechanical properties and thermal strength and chemical properties are closely related.Coke's main physical properties are as follows:
The average heat capacity is 0.808 kj/(KGK) (100 ℃), 1.465 kj/(KGK) (1000 ℃)
Thermal conductivity is 2.64 kj/(MHK) (room temperature), 6.91 kj/(MHK) (900 ℃);
Ignition temperature (air) is 450-650 ℃;
Low calorific value of dry ash-free basis for 30-32 kj/g;

- Q: The difference between coal and coke
- The semi coke production tend to low temperature carbonization, distillation temperature at 600 degrees Celsius, due to a late start, at present the low temperature carbonization furnace single furnace annual output of 30 thousand tons / year in most equipment under low temperature carbonization furnace forum of more than 50 thousand tons / year scale is still at the exploratory and experimental stage, technology of the large-scale equipment is still not mature, can only achieve centralized mass production using a combination of multi furnace technology. The use of coal field is quite widespread, especially in the carbonaceous reducing agent has unique properties, economic advantages are very obvious.
- 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: Used in a restaurant?Dry or dry carbon carbon, coke or coke, and I do not know which word is a word of this sound. The use of coke for iron making. They are more than 1000 yuan price.The main problem is: dry carbon is coke?Toxic smoke, then the chimney can not do? Can I use the blower?
- Dry carbon is not coke, but the combustion will produce a lot of harmful substances, it is recommended to install a more advanced cleaning device. Thank you
- Q: Said the details can add points ah
- 50 kilograms of size greater than 60 mm coke coke samples, in meters Qom in the drum at 50 rpm speed of 100 revolutions (4 minutes), with the aperture is 40 mm (25 mm) sieve screening, measuring more than 40 mm (25 mm) and the weight percentage of the coke, the total weight of the coke drum, denoted as M40 (or M25).
- Q: Effect of coal fineness on coke
- In coking, the caking property is not good and the coke quality is reduced. Therefore, from the perspective of the uniformity of coal, coal fineness of some good. From the operation point of view, the greater the fineness of coal coal bulk density is lower, the production capacity of coke oven is low, into the coke oven, fine coal powder easily by gas is brought out, and easy blockage of ascending pipe, gas collector, affect the normal production of the coke oven, and the set of tar in the trachea increased, the effect of recovery operation. Therefore, from the production point of view, the fineness of coal should not be too large. Bulk coal in the top of the coke oven, coal crushing fineness of the general control in less than 3mm component in the range of 73~83%. Tamping coking, generally about 90%. In this range, the fineness of pulverized coal can meet the requirements of coke quality and coke oven operation. The small coal crushing will reduce the adhesion and the bulk density of coal, so as to reduce the coke quality.
- Q: How coal is turned into coke in the coking chamber
- Simply put is to let the coal in the isolated air furnace heating, volatile volatile, and the rest is cokeOf course, the volatile ingredients to be collected, are the baby
- Q: Why does Coke provide heat when it is fired, it reacts only at high temperatures and why it is needed to provide heat?Which is the exothermic reaction, carbon dioxide or carbon monoxide?
- Generate CO2;Of course, high temperature will produce CO, but not many;Please ask questions
- Q: Coke and coal is one thing
- How coal is formedCoal has been hailed as the black gold, the food industry, it is one of the main sources of energy used in the human world since eighteenth Century. Although its important position has been replaced by oil, but in the future for a long period of time, due to the exhaustion of petroleum, inevitable decline, but because of the huge reserves of coal, coupled with the rapid development of science and technology, the new technology of coal gasification is becoming more mature and widely used, coal will become one of the human production life cannot substitute energy.
- Q: How long should it be to store coke in the open air
- And the most important thing is to avoid the sun. Coal and coke, like the sun, the temperature inside the stack is very high. So try to cool down.
- Q: Natural gas can replace coke smelting pig iron
- No, it's not just the temperature. It takes the chemical reaction of carbon and iron oxide to produce iron.Chemical equation: C+Fe 3O4 - Fe+CO2
