How does an External Combustion Burner work?
The external combustion Burner produces a flame, similar to how a gas dryer, which in turn heats air blowing across coils. The closed-loop coils contain a specialized fluid which turns to vapor. The fluid enters the rotary engine and expands. As it expands, it gives up its heat.
The Heat energy is converted to rotary shaft power. The fluid goes to vapor-phase at about 90F (if using an Organic Rankine Cycle (ORC) fluid. As it exits the engine, it re-condenses and is then heated again, repeating the cycle.
Note: There are number of key design elements not being disclosed. Among other elements, this includes: how to provide excellent flow to the vapor going through the engine, yet maintain a relatively constant temperature throughout the engine housing, even as the vapor keeps expanding.
After giving up its heat inside the engine, it is re-circulated, re-heated, and passes through the Engine again, As it expands inside the Engine, it produces rotary shaft power.
But it does it in a very unique manner, which has the effect of a very long lever, with a very short fulcrum. But for now, we will leave this point for a later discussion. Suffice to say, the NET force inside the expansion chamber causes a net, simultaneous force in a clock-wise direction.
As an external-combustion rotary heat engine, there are further advantages of the FE. For example, the FE maximizes and utilizes both the reactive turbine-effect of a vapor (steam), and also the adiabatic expansive energy of the same heated vapor.
