Thermogravimetric analysis in the study of solid fuels

Abstract

Depletion of fossil energy is the reason for the exploration of the possibility of the use of renewable energy resources. In the article describes a method of thermo-gravimetric analysis and concept, design and execution of the instrument to thermogravimetric measurements placed in the Laboratory of Fuel and Energy Conversion of Institute of Electrical Power Engineering of Poznan University of Technology. The further part of the paper contains the results of the tests carried out on two types of solid fuels (pellets from sawdust and energy willow wood chips ) in the form of a thermogravimetric curves. This analysis is to determine the level of the pyrolysis process temperature and degree of conversion of solid fuels into fuel gas. These studies are conducted by looking at opportunities to improve the energy efficiency of the gasification process of biomass.
