The combustibility test in drop tube furnace and fluidized bed reactor showed that coal gasification fine slag can be well burned in a pulverized furnace requiring combustion temperature >900 °C . 2.2.. Thermogravimetric analysis (TGA)When investigating the characteristics of coal reaction, the devices of thermogravimetry (TG) [19], [23] and drop tube furnace (DTF) [24], [25] are commonly employed. Corresponding to the TG and DTF the heating rates are approximately in the orders of 10 K min −1 [4] and 10 4-10 5 K sec −1 [23], respectively.. . Drop-tube furnace. Drop-tube furnaces (DTF) are essentially vertical pipes heated from the outside, and solid samples pass the reactor due to gravitational acceleration. Particle and gas phase samples are typically taken at the reactor outlet or in a vertical direction along the reactor for varying residence times.

The drop tube furnace (DTF) shown in Figure 4 is a vertical tube furnace used to characterise the devolatilisation and burnout of coal samples at 1100 °C in air at a residence time of 100 ms and to prepare chars for analysis using the TGA.

When the temperature of the MSWI furnace was 850 °C, the I-TEQ value of PCDD/Fs in the flue gas collected at the MSWI furnace outlet was 0.31 ± 0.01 ng I-TEQ/Nm 3, which was much higher than those in the flue gas of the drop-tube furnace. The I-TEQ value in the flue gas sample AG-1 was the reference value for only burning pulverized coal. In this paper, an air-cooled steel probe in a drop tube furnace (DTF) was used as the simulation of heat transfer surface of biomass boilers to collect the deposits during biomass oxy-fuel combustion for analysis. .
