The Gas Turbine and Biomass Gasification Laboratory of the Federal University of Itajubá has a 0.5 kW turbine for teaching purposes, T200D model, Italian made. This turbine is made up of two shafts, with gas generator and free turbine. The unit has a radial compressor, 2 radial turbines and a combustion chamber external to the main body of the gas turbine, which operates with propane as fuel.

The T200D unit allows the performance of thermal experiments such as: calculation of cycle and unit performance, compression efficiency, and combustion. It also enables the monitoring of its behavior during operation for it possesses a digital system to measure the parameters of the process.

In this laboratory, three Capstone gas turbines are installed with maximum capacity of 30 kW and 26% of efficiency.


For the analysis of combustion, the following equipment is present:

• Ecoline 6000 gas analyzer (O2, CO, NOx , SOx);
• Particle concentration in gas meter;
• Cascade impactor;
• Sampling train and measurement of tar percentage in gases;
• Digital pyrometer;
• IKA works adiabatic calorimeter for solid and liquid fuels;
• Depression Gauge;
• Thermometer Gauge;
• Sphere viscometer with thermostatic bath;
• Optical pyrometer for measuring temperatures from 160°C to 1600°C.



The Gas Turbine and Biomass Gasification Laboratory also includes a biomass fluidized bed gasifier coupled to a 30 kW gas microturbine through a gas cleaning system. It was implemented a laboratory to evaluate the quality of the gas produced by the gasifier.

Tests performed in the gasifier allowed checking the operationality of its subsystems.

It was recently installed an absorption chiller at the 30 kW capstone turbine gas outlet, forming a cogeneration system that produces electricity and cold air. This system allows the evaluation of the performance of the cogeneration thermal cycle for different thermal and electric loads.
