Can I retrofit a gasifier to my little portable petrol or diesel generator?
Sadly, in most cases the answer to this is “No”. The reason is that the small generators are typically of the 2-pole type and operate at 3000 rpm for 50 Hz (3600 rpm for 60 Hz). This reduces the weight of both the engine and the generator, improving portability. Wood gas simply doesn’t burn fast enough to run an engine much over 1800 rpm and hence is only suitable for the larger-scale 4-pole generator systems operating at 1500 rpm for 50 Hz (1800 rpm for 60 Hz).
