An integrated system is presented that produces and burns syngas completely into fluegas, and then uses the latter as a thermal input in a triple-pressure cogeneration cycle after first being used in a gas turbine cycle. The study focuses on monitoring the outputs under parameters that are supposed to change frequently while the system is running in a near-real working environment. The primary variables that fluctuate are the temperature of syngas during gasification (T^syn), the moisture content of biomass (MC), the temperature of fluegas after combustion (T^flue), and the concentration of ammonia in the cogeneration cycle (x^NH₃). It has been shown that an increment in the T^syn and the MC leads to a decrease in the work output of the gas turbine cycle, while on the other hand, they increase the work and cooling outputs of the cogeneration cycle. Also, an increase in x^NH₃ benefits the cogeneration cycle's work and cooling production capacity while having no influence on the turbine cycle's work output. However, the rise in T^flue creates contradictory/conflicting conditions in the gas turbine cycle and the cogeneration cycle, causing their outputs to fluctuate when the system is in function. Based on the above results, it is seen the maximums of the outputs from both cycles occur at the same T^flue and x^NH₃, however, the maximums of their respective cycles come at different T^syn and MC. The maximum recorded output from the gas turbine cycle and the cogeneration cycle are 12699.49 kW, 1106.16 kW and 833.73 kW, respectively.
