A new recuperator is now being introduced for small and micro-turbine applications. These applications are characterized by low pressure ratios, exhaust gas temperatures that are suitable for use with stainless steel, and a limited allowance for leakage that does not impair the performance. However high reliability is required, because microturbines typically experience 4000 start/stop cycles during their life, and have to be totally reliable when supplying electricity for applications that are independent of the grid. Recuperated gas turbines have a history of expensive installations, prone to cracking under thermal shocks. The ACTE recuperator has been specifically designed for reliablity, compactness and low cost. This paper shows how these seemingly conflicting requirements are met in the ACTE design.
