A thermodynamic analysis of combined cycle Integrated with Biomass Gasification plant has been performed based on energy balances in a proposed configuration. In this work, we choose paper as a fuel, thermal performance and sizing of such plants have been analyzed at various cycle pressure ratio (rp= 2-11), turbine inlet temperature (TIT = 1300–1500 K) and the heat exchanger cold end temperature difference (CETD = 200–300 K). It is observed that the thermal efficiency of the plant increase with pressure ratio depending upon the TIT and heat exchanger CETD. For a particular pressure ratio, thermal efficiency increases either with the increase in TIT or with the increase in heat exchanger CETD. The specific air flow, which is attributed to the size of the plant components, decreases with the increase in pressure ratio. This decline is sharp at the lower pressure ratio (rp < 4) but slowing at higher pressure ratio values. An increment in the TIT reduces the specific air flow, while a variation in the heat exchanger CETD has no impact on it.
