1.3 Power and efficiency
One of the real advantages of the steam engine is that through the external
combustion he does not depend on high quality fuel. He works with any
kind of fuel, f. ex. coal, wood, oil, peat, any kind of waste etc. This is not
true for the steam engine model, they are fed with dry spirit tablets. Another
advantage of the steam engine is that they produce relatively little operating
noise. What one can hear is the noise of the mechanics and the exhaustion
of the steam, the engine itself runs almost silent.On the other hand we have
a very essential disadvantage. The steam engine has a very low efficiency;
only 10 to 12%, which means only 12% of the involved energy of the fuel is
transformed into kinetic energy.
1.3.1 Comparison: oscillating and
valve-controlled steam
engine
With the model Steam Box and the model D20 one can explore easily the
difference between the oscillating and the valve-controlled steam engine.
Also with the experiments of the Steam Box one can point out the
differences very clearly.
Fig.1.03 on the left side the steam engine model of the Steam Box with the
oscillating cylinder, to the right the model D20 (valve-controlled).
