Non-condensible ejection system for closed cycle Rankine apparatus

Apparatus for ejecting non-condensible gases from a closed Rankine cycle motion producing system including a boiler, an engine, a condenser and means for circulating a condensible working fluid in a closed path through said boiler, engine and condenser, said apparatus comprising:

• a steam ejector having a non-condensibles inlet connected to said closed path, and outlet isolated from said closed path and a steam inlet;
• a steam generating reaction chamber connected to said steam inlet;
• and
• at least one steam producing reactant storage container selectively connectable to said reaction chamber.

An ejector system for use with a closed Rankine cycle apparatus comprising:

• a steam ejector having a steam nozzle aligned with a diffuser, said diffuser defining an outlet from said ejector system, and an inlet to the interface of said nozzle and said diffuser;
• a normally closed, non-condensibles flow control valve having an outlet connected to said ejector inlet and an inlet adapted to be connected to the working fluid flow path of a Rankine cycle apparatus;
• a motor for selectively operating said flow control valve;
• a steam generating reaction chamber in fluid communication with said steam nozzle;
• first and second pressure vessels, each adapted to contain a different reactant of a multi-reactant, steam producing, chemical reaction;
• valve means for controlling fluid communication between said pressure vessels and said reaction chamber.
