Method for performing mechanical work, arrangement for performing mechanical work, and method for converting mechanical energy into electrical energy

Abstract

A method for performing mechanical work. A fuel is combusted in at least one reactor using an oxidizing agent, and mechanical work is performed by expanding in an expander a reaction product resulting from the combustion. Fuel or fuel and oxidizing agent are supplied to the expander to counteract a drop in temperature in the expander during combustion of the fuel in the expander. Furthermore, an arrangement for performing mechanical work via the method and a method for converting mechanical energy into electrical energy, are also provided.
