TT-D40K Model Dual-Station 40kg Simulated Pressurized Coke Oven
I. Product Introduction
The product Dual-Station 40kg Simulated Pressurized Coke Oven, also known as "Load Test Coke Oven", is a next-generation upgrade of traditional test coke ovens. This equipment is used to analyze the coke yield and hot strength indicators (CRI, CSR) of blended coals or single coals, as well as for experimental research on conventional and stamp charging coking. It provides experimental research data for the rational utilization of coal resources and improvement of coke product quality, guiding and improving production. It can also explore suitable coal blending conditions based on the thermal strength indicators of the produced coke, infer the economic feasibility for production, and provide materials for the rational utilization of coal resources.
The company's simulated pressurized coke ovens are available in various designs, including single-station, dual-station, 40kg, 100kg, etc. The dual-station model enables continuous testing, offering advantages such as saving experiment time and electricity consumption.
II. Technical Features
This system is a test coke oven between the 200kg semi-industrial test coke oven and the laboratory 7kg and 20kg small coke ovens. The TT-D40K test coke oven retains the advantages of the 200kg coke oven while overcoming its shortcomings, such as large coal sample quantity, long coking cycle, and high labor intensity. It is a replacement product for the 200kg coke oven. It also overcomes the disadvantages of the laboratory 7kg and 20kg small coke ovens, which have narrow furnace widths and small coke sample quantities. Its single coal charge capacity is ≥40kg, and using a ¼-Micum drum achieves coke characterization similar to industrial coke oven characterization (which is difficult for 7kg and 20kg coke ovens). The unique structural design and three-phase balanced load control, with precise temperature control of the furnace walls individually by computer and PLC, ensure a good correlation between coking results and production coke ovens. The coke strength indicators have good intuitiveness and the test results have good reproducibility. The dual-furnace design improves equipment utilization efficiency and saves time for continuous testing.
This equipment features tight sealing, more uniform three-zone heating, and the ability to simulate pressurization. The CSR values are consistent with those from actual production of large industrial coke ovens.
