Abstract

Power generating station with an integrated coal gasification plant, with an air separation plant, a coal gasifier and a heat exchanger and dust removal plant connected to the coal gasifier, as well as with a gas turbine and steam power generating part connected to the heat exchanger and dust removal plant part. An ammonia synthesis plant is connected to the coal gasification plant with the interposition of a gas purification plant and a gas decomposition plant. Part of the exhaust gas produced in the ammonia synthesis can be fed as so-called purge gas to the combustion chamber of the gas turbine together with the gases separated in the gas purification plant and in the gas separation plant, and part of the dust-free raw gas of the coal gasifier.
