Abstract
The crank type in two types of small-sized generators built as a trial for study must be equipped with a control device which is able to maintain the plunger thrust fluctuations of a compressed biomass feeder within a given range set up in advance. This study was done to develop the control device. The generator equipped with the control device made on an experimental basis was operated at the thermal decomposition temperatures of 700 and 900°C.
Throughout the operation, the plunger thrust fluctuations could be maintained within the desired control amount of 5.0-8.5MPa{50-87kgf/cm2}. As a result, it was confirmed that the developed control device could be put enough for practical use.
