Product introduction

The performance differences of coal measure needle coke and oil content needle coke include the following points.

1. Under the same conditions, the graphite electrode made from oil series needle coke is easier to form than coal series needle coke.

2. After the graphitization products of oil series needle coke are made into graphite products, their density and strength are slightly higher than that of coal measure needle coke,Hydrogenation Project,Hydrogen Production Eguipment,Heating Furnace Equipment which is caused by the expansion of coal measure needle coke in the graphitization process.

3. In the specific use of graphite electrode, the thermal expansion coefficient of oil needle coke graphitization product is low.

4. In terms of the physical and chemical indexes of graphite electrodes, the resistivity of oil series needle coke graphitization products is slightly higher than that of coal series needle coke products.

5. The most important thing is that the amount of coal needle coke expands in the process of high temperature graphitization. When the temperature reaches 1500-2000℃, the heating rate should be strictly controlled, rather than rapid heating, and it is best not to use series graphitization process.

6. The calcined oil needle-shaped coke has a smaller content and finer particle size, while the coal measure needle-shaped coke has a smaller content and a larger particle size (35-40mm), which can meet the grain size requirements of the formula, but brings difficulties to users' crushing.

Product parameter

Name: Needle coke heating furnace

Application: petrochemical industry

Design temperature: ≤800℃

Megawatt: 5-50 MW/unit

Specification：：Cylinder diameter 2-8 meters

The square can be customized in length, width and height

Note:

1. before opening the furnace should be furnace tube, parts, ancillary equipment, process pipelines, instruments and other instruments for a comprehensive inspection, confirm the process is correct, all equipment and parts intact, equipment and pipelines without debris, instruments and instruments flexible and convenient operation, real and accurate data;

2. Steam through the process pipeline and equipment of the furnace system to ensure smooth process flow. When all checks are qualified, the fuel gas line shall be completely replaced with nitrogen and then introduced to the fuel gas line. When fuel gas is introduced, pay attention to the oxygen content of air in the pipe <1%. Before ignition, the content of combustible gas in the fuel gas pipeline is detected, and the ignition operation is carried out after the ignition conditions are met.

3. Use steam stoves in strict accordance with operating rules;

4. Heating, close the steam valve, such as furnace and pressure, must be able to wait for the pressure to zero inch after the pot (box) to take.

Compared with other companies, the advantages of our products are: good thermal insulation effect, high thermal efficiency, good energy saving effect, low smoke exhaust temperature, adjustable dilution ratio, good selectivity, less high boiling substance; Emission standards, small pollution, small footprint.

Product process: blanking, assembly, welding, testing, anti-corrosion, installation, commissioning.
