In the advanced glass melter the glass batch is rapidly heated to glass melting temperature by convecting the batch in the combusting gas. Total heating time for the batch, which has particle sizes in the 10‐ to 150‐μm range, is of the order of 50 ms. A computer model has been developed to predict thermal history of the particles including temperature and other phenomena such as calcination and fusion. It also predicts particle velocity and acceleration in the gas and inertial separation of particles from the gas at the target. The model was developed to help in choosing particle sizes of different batch ingredients, defining the operating envelope and optimizing system performance. Experimental measurements of heated batch temperature show good agreement with numerical calculations.
