Regenerative gas generator

A system for generating reaction products having elevated temperature and pressure, comprising:

• a first chamber comprising:
• an inlet to receive hydrogen peroxide having a concentration between about 15% and about 62% by weight;
• a reactor to decompose the hydrogen peroxide having a concentration between about 15% and about 62% by weight, to generate oxygen and water vapor;
• and
• an outlet to allow the generated oxygen and water vapor to exit the first chamber;
• a second chamber comprising:
• a first inlet to receive the generated oxygen and water vapor from the first chamber;
• a second inlet to receive a fuel;
• a reactor to catalytically combust a mixture of the oxygen and fuel to generate reaction products having elevated temperature and pressure;
• and
• an outlet to allow the reaction products to exit the second chamber;
• a container having a wall, the first and second chambers are disposed within the container,
• a partition disposed within the container and between the first and second chambers, the container wall and the partition defining a passageway to receive reaction products exiting the second chamber and to channel the reaction products into contact with external surfaces of the first and second chambers;
• and
• an outlet to the container to allow the reaction products to exit the system.
