Destructive distillation experiment material is inserted by the feed bin according to experiment condition；The thermocouple for surveying material temperature is inserted into feed bin respectively simultaneously
On corresponding contact point；
By the air inert gas replacement in whole casing；
The heat-proof device is closed, starts the heat-insulation and heat-preservation burner hearth heating schedule；
After the heat-insulation and heat-preservation fire box temperature to assigned temperature, the heat-proof device is opened, the lower furnace body is carried into feed bin
Move up and be connected with the upper furnace body, start destructive distillation, and destructive distillation oil gas is collected from the oil and gas separating system end of destructive distillation oil gas vent；
After destructive distillation terminates, inert gas atmosphere will be set as in the inert gas cooler bin, by the lower furnace body together with described
Feed bin moves down, and is then shut off the heat-proof device；
After temperature of charge drops to desirable value, take out material and analyzed.
9. the method for destructive distillation as claimed in claim 8, it is characterised in that the inert gas is nitrogen.
10. the method for destructive distillation as claimed in claim 8, it is characterised in that the heating-up temperature during heater destructive distillation is 400
℃-1600℃。
