Schematic diagram of the scale-up experimental device: (a) temperature recorder; (b) thermocouple; (c) electronic balance; (d) heater; (e) sleeve; (f) quartz tube; (g) Cambridge filter; (h) wires; (i) thermostat; (j) power supply; (k) glass rotor flow meter; (l) vacuum pump; ① measurement point on the surface of the heater; ② measurement point at a distance of 0.5R from the surface of the heater; ③ measurement point at a distance of R from the surface of the heater (on the inner wall surface of the sleeve); ④ measurement point at a distance of 0.25R from the surface of the heater; ⑤ measurement point at a distance of 0.75R from the surface of the heater; ⑥ measurement point(s) for the temperature of the aerosol. The letter “R” represents the distance between the inner surface of the sleeve and the surface of the heater, which is 15.6 mm.
