The Open
Oscillatory Approach
Hydram Research's engineers have discovered and developed a new and more efficient way of boiling water and generating process steam for industrial applications. The elegant open oscillatory approach is a departure from the method we're all accustomed to, attacking the liquid with heat until it bubbles - how we've boiled water since we lived in caves.
The method can be described as exciting and maintaining oscillations of a warm multi-ton liquid piston so that it shoots several meters up and down a thick pipe.
The process consists of three stages:
1
Flash Evaporation
Low pressure steam forms in the wake of the falling liquid piston, which drops due to its weight and pressure conditions in the wider side tank.
↓
2
Compression with Liquid Piston
After dropping several meters the liquid piston has overshot and naturally rushes back up, rapidly squishing the steam. The trick is not to allow the steam to condense back to droplets, but to let the piston pressurize and heat it up - similar to how a diesel engine heats air.

Ejection
As the liquid piston approaches the top again, the steam's pressure forces a valve to open and the steam is ejected into the steam header to do useful work - like district heating, cooking food, or creating paper.

Q: Wait, that seems complex - why not just heat the water?
A: The main advantage of doing it this way is that most of the steam's energy is derived from a process called "evaporative cooling". That means the steam is generated using two sources of energy: (i) constant source of warmth to keep the system from cooling (called "low-grade waste heat" and is free and abundant at industrial sites) + (ii) energy to maintain the oscillation (not free). Bottom line: more steam, less costly energy.
