Abstract

This paper presents the results of a thermodynamic and economic analysis concerning the use of gas from gasificationof biomass in a cogeneration system with an internal combustion piston engine, working for the needs of a districtheating network, with power of 1.5 MW in biomass supplied. The data on the gas generation and purification processwere taken from real experiments conducted on a research installation with a fixed bed gasifier at the Institute forChemical Processing of Coal in Zabrze. Electricity and heat generation eciency and electric and thermal power ofthe system were primarily used as indicators of the thermodynamic evaluation. The economic analysis was carried outusing discount methods, taking into account the existence of support mechanisms in the form of the colorful certificates.A sensitivity analysis of evaluation indices to the change of selected characteristics was performed.
