ADVANCED COMBINED CYCLE SYSTEMS AND METHODS BASED ON METHANOL INDIRECT COMBUSTION

摘要

A methanol indirect combustion combined-cycle power generation apparatus and method. A liquid methanol input stream is evaporated to provide a gaseous methanol stream which is converted to syngas that is combusted in a gas turbine assembly to drive a first electrical generator and produce an exhaust gas. Heat from the exhaust gas of the gas turbine assembly is used to produce first and second steam streams. The first steam stream drives a first steam turbine and provides the heat required for converting the gaseous methanol stream to the syngas combustion stream. The second steam stream drives a second steam turbine and provides the heat required for evaporating the liquid methanol input stream. A second electrical generator is driven using at least one of the first and second steam turbines.
