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, steam cleaning, hot water heating, process heat generation, and other adaptations
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
- Interchangeable water pumps for steam engine, hot water, or space heating application
Materials calculations:
- Heavy-walled tubing, 100 feet, not to exceed 50 pounds in weight
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
- Long lifetime under continuous use (10 years)
- Compatible with Babington burner or wood gasifier flame inputs
- 1 hp per lb power to weight ratio possible
Ecology:
- Easily connectability of coils for scaling purposes
- Easy connectabilty for various uses
