GPCA - a new and advanced in-situ method for characterization of solid fuels

摘要

The Gas-Potentiomelric Combustion Analysis (GPCA) as a new and advanced in-situ method for characterization of solid fuels is introduced. It bases on the investigation of the burn-up behaviour of a fuel sample in a lab scale lluidized bed reactor by measuring the oxygen concentration continuously and in-situ. Therefore a special designed solid electrolyte oxygen sensor is applied. As result several fuel specific parameters are obtained, useful for evaluation of the burn-up behaviour of the fuel (fuel characterization) and for optimization of the reactor design and the combustion procedure as well.
