So, the objective is to generate a water flow similar to a household water system (60 PSI) inside copper pipes that have 30 coil turns that are inside a stove that burns wood.
A monotube steam generator is basically a "boiler" without a pressure vessel/steam drum, generating steam pumping water through a coiled tubing above a heat source, transforming the water in steam in the process.
The idea here is to make a pumpless monotube boiler, the water will eventually evaporate and push the hydro generator, eventually emptying the copper coil, which will make the water come back into the tubing.
The Problem:
The problem is that this seems too much like the putt putt boat engine, because I'm assuming the water will only flow into the coil once the water inside it turns into steam.
And I found this PDF that affirms that the putt-putt boat only achieves 0,02% of efficiency. And the closest thing I found to this contraption was this putt putt heat engine water pump, but they didn't specify the efficiency of the pump.
There are also Water-tube Boilers, but I don't know if this system is the same or something else. Simply because the tubes in the water tube are separated and connected to a somewhat pressure vessel. And they also need a water pump.
The question:
How efficient would this system be in generating steam pressure (and thus, work)?
Here are the measurements of the stove and copper tubing:
- Height of stove: 23 cm
- Diameter of stove: 8cm
Copper pipe has the following measurements:
