Abstract:
1. A hydrogen combustion system with closed-cycle recycling of exhaust gas, comprising: a hydrogen supplier which supplies hydrogen used as a fuel, a combustion chamber which is located in an external combustion engine and connected to a hydrogen supplying pipe of the hydrogen supplier in which the hydrogen supplied from the hydrogen supplier is combusted, a condenser which converts hot exhaust gas emitted through a discharge pipe installed on an outlet of the combustion chamber into cold exhaust gas and condensed water, a secondary coolant flow control valve installed for controlling a rate of water condensation in the condenser, and a recycling pipe which is connected between the condenser and an inlet of the combustion chamber and performs recycling of a part of the cold exhaust gas from the condenser to the inlet of the combustion chamber, wherein a blower is installed at a passage of the recycling pipe for driving and controlling a flow of cold intake gas, which is a mixture gas of oxygen, dilution gas and water vapor, into the combustion chamber.
