Abstract

FIELD: power plants working on hydrocarbon fuels and oxygen under water. SUBSTANCE: power plant has fuel reservoir and liquid oxygen reservoir, combustion product cooler-divider for separating gaseous products and water provided with water receiver, carbon dioxide cooler with carbon dioxide and non-liquefied gaseous combustion product receiver and oxygen preheater. Oxygen reservoir is divided into at least two tanks. Plant is also provided with excess oxygen liquefier for liquefying excess oxygen contained in combustion products. Oxygen liquefier is provided with oxygen inlet branch pipe connected with delivery branch pipes of tanks by means of pipe lines through valves, oxygen outlet branch pipe connected with oxygen inlet branch pipe of carbon dioxide liquefier, liquefied excess oxygen drain branch pipe connected with intake branch pipes of tanks by means of pipe lines through valves, gaseous combustion product inlet branch pipe connected with gaseous combustion product outlet of carbon dioxide liquefier, nonliquefied combustion product outlet branch pipe connected with nonliquefied combustion product inlet branch pipe of receiver. EFFECT: isolation of power plant from surrounding medium as far as combustion products are concerned.

Claims (1)

To do this, in a well-known power plant with a Stirling engine for hydrocarbon fuel and oxygen, containing a fuel tank and a tank with liquid oxygen, a cooler, a separator of fuel combustion products into gaseous and water with a water collector, a carbon dioxide cooler with a collector of carbon dioxide and non-liquefied gaseous combustion products, a heater oxygen, the oxygen tank is divided into at least two tanks and a fluidizer of excess oxygen contained in the combustion products of the fuel is introduced. In this case, the oxygen liquefier is equipped with an oxygen inlet pipe connected by pipelines through the valves to the pressure nozzles of the tanks, an oxygen outlet pipe connected to the pipe of its entrance to the carbon dioxide liquefaction, a liquefied excess oxygen discharge pipe, connected by pipelines through the valves to the receiving pipes of the tanks, a gas inlet pipe products of combustion of fuel connected to a pipe of their exit from a carbon dioxide gas liquefier, a pipe of exit of fluidized products of combustion connected to with the pipe of their entrance to the collection.
