ANALYSIS OF A REHEAT GAS TURBINE CYCLE WITH CHEMICAL RECUPERATION USING ASPEN

摘要

Gains in the power output and thermal efficiency of industrial gas turbines have occurred in the past, primarily from increased firing temperatures and operating pressures. More recently, there is growing interest in investigating advanced cycle concepts that make use of one or more of the following performance enhancement modifications: compression intercooling, reheat expansion and exhaust heat recovery. Recent attention has focused, in particular, on the chemical heat recovery concept. The "waste" heat in the turbine exhaust is used to convert a methane-steam mixture into a hydrogen-rich fuel in a methane-steam reformer.
