✦ Synopsis

The paper investigates the sintering and crystallization behaviour of a LizO-AlsOs-Si02 glass powder containing TiOz and ZrOz. In-situ measuring methods of high-temperature dilatometry, high-temperature X-ray diffractometry and DTA at heating rates between 0.5 and 20 K/mm were conducted. By comparing the results of the different methods the shrinkage could be explained as an overlap of sintering and crystallization processes. As the heating rate increases, the sintering and crystallization processes are more sharply separated, so that higher final densities of the sintered samples are possible.

Gasification of the biofuel or the waste material takes place in a fluidized bed gasifier, preferably a circulating fluidized bed gasifier. The gas produced in the gasifier is introduced into a boiler equipped with fossil fuel burners, typically burners for pulverized coal. The gas is introduced at
