Micro gas turbines have become an increasingly popular form of small-scale power generation due to their high efficiencies and low emissions. Microturbines are versatile being able to operate on fuels ranging from diesel to natural gas and hydrogen. Microturbines also have potential to utilise solar thermal energy as a heat source in hybrid and cogeneration power plants. A solar dish can be used to assist or replace the heat added by the fuel to further reduce emissions of a microturbine. In this work, a commercial microturbine was experimentally tested before being incorporated with a solar dish and receiver setup at the University of Pretoria. The microturbine produced 1480 W electrical power when operating at a turbine inlet temperature of 1088 K. The microturbine had an efficiency of 3.55% and showed potential for use in combination with a solar dish, especially in industries like smelters or bakeries who require large amounts of heat energy and could benefit from also having electrical power.

摘要

Micro gas turbines have become an increasingly popular form of small-scale power generation due to their high efficiencies and low emissions. Microturbines are versatile being able to operate on fuels ranging from diesel to natural gas and hydrogen. Microturbines also have potential to utilise solar thermal energy as a heat source in hybrid and cogeneration power plants. A solar dish can be used to assist or replace the heat added by the fuel to further reduce emissions of a microturbine. In this work, a commercial microturbine was experimentally tested before being incorporated with a solar dish and receiver setup at the University of Pretoria. The microturbine produced 1480 W electrical power when operating at a turbine inlet temperature of 1088 K. The microturbine had an efficiency of 3.55% and showed potential for use in combination with a solar dish, especially in industries like smelters or bakeries who require large amounts of heat energy and could benefit from also having electrical power.
