CombuSteam SOH-Gas Generator

Orbiting SOH-FlameTorch for Heating Zirconia Up To Ultrahigh Temperatures (900-4,300 deg.C) Concept - Application for Advanced CombuSteam Generator

Here is one of our earlier concepts for effective heating and full harnessing the enormous plasma energy of the SOH's flame, while heating some refractory materials up to their melting and boiling point, as for example Zirconia ( ZrO2, 2,715 deg.C Melting Point, 4,300 deg.C Boiling Point). We choose Zirconia first of all because it is the hard material with the best Oxidation Resistance on Earth. 
Alongside with it's ultrahigh temperature melting and boiling points, which can be reached while heated by SOH's's flame.

SOH flame's extreme destructive heating and oxidation power is a major problem. If we use static torch for heating a piece of Zirconia, a hole of molten and boiling material will be punched in the point of the flame's projection soon.

Our basic idea to protect the heated material was to make the torch to move in a circle or eclipse contour. Thus the hot path has some time to cool down for a while. This way we both heat the Zirconia pad, up to the possible maximum, and protect it against destruction.

Here is a tentative drawing of such a set up option.

Moving the torch slowly (10cm/sec) we've seen a thin path of molten material left by the flame. After repeating this move, following the same path, again and again, we had finally a thin path of Boiling Zirconia, with a temperature of 4,300 deg.C or even more, made by a SOH's tiny (0.015mm nozzle diam.) micro-flame.

Measuring the pad's temperature by a thermocouple, we registered over 1,200 deg.C, 1-2mm close to the molten flame-path, and 900-950 deg.C, 5 mm away.

Adjusting precisely : -- speed of the torch's circulation, -- the SOH gas flow (by adjusting the gas pressure from the electrolyser, and/or the nozzle's diameter), and -- the Zirconia Pad's thickness, we can control the safe level of melting and boiling, and the distributed heat, close to the flame's path.

Inside the eclipse, shaped by the fire path, we can put a copper-plated, steel steam pipe element, filled with water - to be heated and evaporated into hot steam :

The 0.5mm thick Copper Coating (Brazing) of the steel pipe's surface, and the water inside the tube, act as perfect thermal exchange agents, to transfer the ultra-heat produced by the HHO flame, from the Zirconia hotpad, to the Steam Turbine (or Piston Steam Engine) for Power Generation.

Zirconia hot pad is being pressed tightly or welded to the steam pipe by SOH's flame. This is an amazing property of the SOH's flame to weld firmly different materials together, like steel or glass to ceramic, etc., which no other gas or arc welder can do.

Welding Zirconia pad to the pipe can guarantee a direct and best possible heat transfer.

Due to the dissimilar level of material extension between the pipe and the Zirconia hot pad, the last one will be cut into shorter elements, allowing the pipe to extend easily, without danger of breaking the ceramic hot pad.

The element shown above will be multipled and assembled into an integrated Combustion-Steam (Combusteam) Modular Panel (or Combusteam Generator). Here is an optional construction :

SOH MMC Panel will be assembled of several modules, 120mm long each. Torches will be fixed on a 2D Common Rail Frame, driven by stepper motors, screws, or hydraulic / pneumatic Actuators, in two direction - X and Y, in order a close circulation of the torches to be shaped. Every torch will be protected by a water-cooled shield.

During our lab experiments we discovered, that when measured, the reflected flame generates even more energy than the main one. So we designed a SOH Flame Combustion Zirconia Chamber, which could harness almost the whole potential energy, hidden in the SOH's flame :

Flame chamber will be shaped as a hollow profile in the zirconia pad's body, along the flame path.

Here is another version of double-sided SOH Gas Combustion Chamber :

According to our engineers, a Combustion Panel, assembled of 200 modular elements with 200 SOH Gas torches 0.015mm tip, as shown above on Pic. 5, made of steel pipe with external diameter 22mm and internal diameter 18 mm, brazed with 0.5 mm copper thermal conductive coating, with Zirconia hot pad welded to it, will produce hot steam ( 2t/h, 10 bar, 185 deg.C ), enough to drive a 70 kW Piston Steam Engine, coupled with one 50 kW AC220V and one 20 kW DC14V Power Generator - for supplying the water electrolysis in the SOH Gas-Generator, producing 20,000 L/hr SOH gas. Outlet steam (2 bar, 2 t/h, 120 deg.C) can be used for heating or cooling (through Inverter).
