How much is Shaoxing coke powder per ton

Use of coke powder:
The adsorption of dedusting coke powder and the continuous extraction dephenolization process are used to reduce the oil content of residual ammonia water and other pollutant indicators, improve the operation of ammonia distillation process, and solve the problem of easy blockage of ammonia distillation tower and heat exchanger.

As anode materials for lithium batteries, coke powder can be used as raw materials to prepare anode materials for lithium batteries and other new high value-added carbon materials. The mixture of coke powder, tar and catalyst is kneaded, shaped and carbonized to make anode carbon rod for arc.

Coke powder combustion operation:
1. Control of injection system: large injection pressure, large injection volume, small pressure, small injection volume. Pay attention to the change of injection pressure, and the tank pressure and fluidized gas volume are stable; Do not adjust the fluidizing gas volume during operation. Fluidized gas volume change. The change of powder injection conditions and unstable injection amount will affect the amount of powder and cause temperature fluctuation in the furnace; Check the relevant valves of the injection system. Each valve has good performance;
2. Control of glass melting: observe the flame condition in the kiln and coke powder feeding condition through industrial television; According to the flame burning condition in the kiln. Adjust relevant parameters at any time; Grasp the function and characteristics of each regulating valve, and adjust relevant valves in a fast and good way in case of abnormal conditions such as difficult blanking of powder; Patrol the relevant parts every hour. According to coke powder blanking. Replace or adjust the coke powder injection in time. Good performance of spraying;
3. Combustion temperature control: the combustion temperature of the furnace is unstable, which is mainly related to the coke powder supply, coke powder quality, gas-solid two-phase flow transportation stability, and atomization effect. In the coke powder combustion system, the key equipment shall be standby. Use burner to ensure stable operation of coke powder combustion system. Increase coke powder flow. The kiln temperature can rise, and vice versa;
4. Control of flame length: coke powder is fed by pneumatic two-phase conveying pump, and the flame length is controlled by adjusting the frequency of the powder pump and the pressure of feeding powder. The higher the frequency of the powder pump, the longer the flame. The higher the pressure of powder feeding, the shorter the flame (the higher the pressure, the less powder). Use only after adjusting the flame length;
5. Control of flame angle: the adjustment of coke powder flame angle is consistent with the adjustment of heavy oil flame angle. The adjustment is based on the principle that no arch is burned on the flame, no glass level is hit on the lower flame, and no batch surface is hit. The coke powder can be fully burned out, which is conducive to heat transfer. In production, the angle of the burner (powder injection) is 2 °~3 ° smaller than the oil angle when burning heavy oil;
6. Control of flame stiffness: adjust the flame stiffness by combining atomizing gas and powder feeding gas. When adjusting with atomizing gas, consider the small use of residual gas. Adjust the flame stiffness in combination with the pulverized coal feeding pressure. The greater the opening of the needle valve of atomizing gas, the greater the pressure of powder feeding, and the greater the flame stiffness;
7. Control of flame black center: the black center of coke powder flame is longer than that of oil flame. The black center of the flame is mainly adjusted by adjusting the amount of atomizing gas and pressure. The greater the atomizing gas pressure, the greater the gas volume. The better the atomization effect, the shorter the black center, on the contrary, the longer;

What are the functions of coke powder
1. Coke powder acts as reducing agent, heating agent and column framework. The use of coke instead of charcoal in ironmaking blast furnace has laid the foundation for the large-scale modern blast furnace;
2. Coke powder is mainly used for blast furnace ironmaking and blast furnace smelting of copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metals;
