Abstract
The constant rise in electricity demand has challenge researchers around the world to reduce the costs and increase the availability of the distributed generation systems. At the same time addition, it is possible to observe a growing necessity of diversification of the energy sources used worldwide, due to the scarcity and environmental impact of the traditional energy sources. In this scenario, the second and third-generation biofuels are being viewed as a promising alternative, especially when considering the use of microturbines in distributed generation systems. Microturbines are turbo generators with capacity from 30 and 300 kW. These prime movers can operate with different kinds of fuel, such as gasoline, diesel, ethanol, natural gas and biodiesel. The behavior of microturbines when burning most of these fuels is relatively well known, but is of special interest to determine their performance when operating with biobutanol, lignocellulosic ethanol, biodiesel from sugar cane and from algae, since the production of second-generation biofuels, and in some cases of third-generation, is already reaching a commercial stage. Thus, the main objective of this paper it to evaluate the performance (efficiency, specific fuel consumption, deviation of the power generated, etc.), for different load conditions, of a 30 kW microturbine when burning these fuels, as well as to identify possible limitations and necessary modifications for its operation. The analysis will be carried out using data obtained from a mathematical model and from an experimental facility built in one of the laboratories of UNIFEI – Univ. Federal de Itajubá.
