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
