ABSTRACT OF THE DISCLOSURE: A method of producing energy from solid, fossil fuels high in inerts, comprising the steps of: burning the fuel to heat water for producing steam and to produce non- combustible flue gas under substantially atmospheric pres- sure with preheated burning air, expanding the thus produced steam in a steam turbine, cooling at least part of the flue gas to a first temperature by heat exchange between the flue gas and a cooling gas, dedusting the cooled flue gas, com- pressing the dedusted flue gas, using a liquid desulfurizing agent for desulfurization of the compressed flue gas, using the compressed desulfurized flue gas as the cooling gas, expanding the cooling gas heated by the heat exchange in a gas turbine, and cooling the expanded cooling gas by heat exchange between the expanding cooling gas and air wherein the heated air is used as preheated burning air for the atmospheric burning of the fuel. Thereafter, compressing the obtained cooling gas after the desulfurization for pro- viding a pressure corresponding to the operational inlet pressure of the gas turbine wherein the compressing step is prior to the cooling step. And a device to carry out this method.
