Interesting "external articles" about the theme woodgas
Professionals often argue that small woodgas power plants are inefficient.
Our credo says: Cogeneration woodgas power plants have to be adjusted to the demand of heat, electric power has to be a byproduct and not vice versa.

Our point of view
- biomass accrues at the forest of the owner, with short routes of transport
- heat is utilised on site
- entire or excess feed of electricity to the public grid
Also Carl Benz started small and did not build the S-class first!

Building a woodgas plant with low material costs.
The hours of work can only be regarded as leisure time.
Experimental setup with a 11KW fast running induction machine:
Has been proven to be improper, the starting torque was too low for starting up.(auxiliary engine was required for start up).
Furthermore the construction has been very noisy at 3000 rpm.
Installation of some measurement sensors:
(all temperatures, amount of water throughput, Current measurement for Power calculation(cos Phi, apparent power, reactive power and active power), revolution speed)
Programming of the analysis software for visualisation and logging of the measured data Calculation of the overall efficiency
Construction of the exhaust gas cooling system
Refinement of the visualisation
Electronics for conditioning of the sensor signals
For improving the thermal output efficiency the gas generator, the gas cooling system and the sedimentation tank have been totally coated by a 12cm fireproof thermal isolation. This increased the thermal yield about one third.
