1. Equipment name

TT-YLD1-40KG type simulated pressure test coke oven (load test coke oven), loaded coke oven

Second, the use of equipment

Analyze the coke yield, chemical product yield, gas yield of coal blending single coal, quantitatively simulate the mechanical strength indicators (M40, M25, M10) hot strength indicators (CRI, CSR) of coke.

Experimental research on conventional tamping coking. Provide experimental research data for rational utilization of coal resources improvement of coke product quality for guidance improvement of production. It is also possible to explore suitable coal blending conditions based on the cold thermal strength indicators of the produced coke, infer the economy possibility of production, provide information for the rational utilization of coal resources.

Three, technical characteristics

This system is a test coke oven between the 200kg semi-industrial test coke oven the laboratory 7kg 20kg small coke oven. TT-YLD1-40KG test coke oven only retains the advantages of 200kg coke oven, but also overcomes the shortcomings of large coal sample volume, long coking cycle high labor intensity. It is a replacement product for 200kg coke oven. At the same time, it also overcomes the shortcomings of the narrow width small coke sample volume of the laboratory 7kg 20kg small coke ovens. It has a coal charge of ≥40kg at a time achieves coke identification industrial coke ovens with a 1/3 mcomb drum The purpose of coke identification is similar (this is difficult for 7kg 20kg coke ovens). The unique structural design the use of three balanced loads are realized by the computer PLC to achieve individual precise temperature control of the furnace wall, ensuring a good correlation between the coking results the production of coke ovens. Coke strength indicators are intuitive, can measure M40 ( M25) M10, as well as reactive CRI post-reaction strength (CSR). The test results are reproducible.
