The automatic control system of 40kg experimental coke oven is a single-hole carbonization chamber simulating industrial coke oven.The lower furnace door is used to fill the sample at the bottom, and the left and right sides are heated.The three balanced load electric heating systems are controlled by microcomputer, and the temperature of the heating bodies on both sides of the furnace wall is controlled precisely, which ensures that the coking results have a good correlation with the production of the coke oven.The coke strength index is intuitionistic and the test results are reproducible.M40 and M10 can be measured, as well as M25 and M10.Application fieldIt is suitable for coal, coke, metallurgy, geology, chemical industry and other industries as well as the laboratory of scientific research institutions in colleges and universities.With a standardThe enterprise standardTechnical characteristicsThe furnace body adopts microcomputer automatic control to realize symmetrical and independent heating on both sides of the furnace wall.User-friendly control interface.Reasonable structure and accurate value.Technical parametersEffective chamber length (mm) : 450Effective chamber width (mm) : 350Effective height of the chamber (mm) : 600Effective volume of the chamber (m3) : 0.071Coking time (h) : ≥10hCoal loading (dry coal) (kg) : 40-60Loading density (Kg/m3) : 720-1050Furnace wall temperature (℃) : 1100-1200Coke cake center temperature (℃) : 900-1050Operating temperature (℃) : 1300Coking speed :(℃/min) 1-3Coking method: conventional coking, tamping cokingControl accuracy: the temperature difference between the two sides of the furnace wall is no more than ±5℃, and the set temperature value and the actual temperature value are within ±5℃
