Abstract


This paper presents the results of a thermodynamic and economic analysis concerning the use of gas from gasification
of biomass in a cogeneration system with an internal combustion piston engine, working for the needs of a district
heating network, with power of 1.5 MW in biomass supplied. The data on the gas generation and purification process
were taken from real experiments conducted on a research installation with a fixed bed gasifier at the Institute for
Chemical Processing of Coal in Zabrze. Electricity and heat generation eciency and electric and thermal power of
the system were primarily used as indicators of the thermodynamic evaluation. The economic analysis was carried out
using 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.

Keywords


Biomass gasification, CHP units with piston engine, Thermodynamic analysis, Economic efficiency
