Coal Ge Jin Low Temperature Dry Distillation Tester

AVGJCoal Ge Jin Low Temperature Dry Distillation TesterMainly used for coal mine laboratories, coal coking industry, related teaching and research, quality supervision, etcUnit, conduct testing and analysis on physical and chemical indicators such as tar yield, semi coke yield, and dry distillation water yield of lignite and bituminous coal.

The Gejin low-temperature dry distillation test is a comprehensive test with multiple indicators, including coking index cokeThe determination of type includes the determination of semi coke yield, tar yield, and total water yield of dry distillation products. According to GB/T1341 "Gold content of coal"The basic principle of the low-temperature dry distillation test is to place the coal sample in a glass dry distillation tube and send itEnter the pre heated dry distillation furnace to 300 ℃, isolate air heating at a heating rate of 5 ℃/min, and dry distillation at a temperature of 300-600 ℃And keep warm for 15 minutes, measure the yield of semi coke, tar, and total water, and compare the semi coke with the coke type in the standard to determineIts focal shape.

1. The furnace body is made of bronze alloy with a copper tin ratio of five to two,

2. The sequential arrangement of heating rods in Germany ensures that the temperature difference between the furnace holes is less than 1 ℃ and the temperature control error is less than 3 ℃

3. Temperature controller: intelligent LED display

4. Eight heating rods cross to generate heat and balance the temperature of the homogenizer furnace body

Heating rods I and VIII: 0.45KW
