Flash Boiler Specifications

Summary:

• System consists of heat exhange coil, connections, feedwater injection, shroud, heat-source attachment, and pressure release
• Nestable, scalable, configurable long-lifetime flash steam generation coils
• Applications to vehicle steam engine power, cogeneration (combined heat and power systems), point-focus solar engine power,

Cost-Related Features:

• Lowest materials cost for a given performance
• Simplest to fabricate, therefore lowest fabrication cost
• Advanced techniques of fabrication utilized only when necessary to achieve cost
• Fabrication tooling preferrably simple, but secondary to fabrication cost
• Uses commonly available parts
• Replicable
• Cost of $10/hp output embodied in coil material

Materials calculations:

• Heavy-walled tubing

Flexibility and Performance:

• Scalable in steam power output from 1 - 100 hp by coil nesting or coil extension
• Steam power density of 1-20 hp/gallon of volume
• Pressure up to 1000 psi
• Modular
• Coil configuration for chimney/flue pipe heat recovery applications
• Nestable coils for higher power density applications
