Development of a new type of thermogravimetric analyser with a mini-tapered fluidized bed. Effect of fluidization of particles on the stability of the system

摘要

A new type of thermogravimetric analyser (tapered fluidized bed thermal gravimetric (TFBTG) analyser) has been developed, consisting of a balance, tapered fluidized bed and separate gas nozzle. The relations between the gas velocity and pressure drop and between the gas velocity and weight change were studied experimentally. The effect of the fluidization of the particles on the balance is discussed on the basis of a cold model experimental system.
