An arrangement including at least one steam turbine and one condenser is provided. Further, a method to operate such an arrangement is provided. A regenerative deheater is arranged in the steam flow between the steam turbine and the condenser, by which the steam, superheated exhaust steam, exiting the steam turbine is cooled down before entering the condenser and by which a feed-water stream is heated up.

Arrangement with a steam turbine and a condenser

The power plant combusts a hydrocarbon fuel with oxygen to produce high temperature high pressure products of combustion. These products of combustion are routed through an expander to generate power. The products of combustion are substantially free of oxides of nitrogen because the oxidizer is oxygen rather than air. To achieve fast starting, oxygen, fuel and water diluent are preferably stored in quantities sufficient to allow the power plant to operate from these stored consumables. The fuel can be a gaseous or liquid fuel. The oxygen is preferably stored as liquid and routed through a vaporizer before combustion in a gas generator along with the hydrocarbon fuel. In one embodiment, the vaporizer gasifies the oxygen by absorption of heat from air before the air is routed into a separate heat engine, such as a gas turbine. The gas turbine thus operates on cooled air and has its power output increased.
